RedEye, by Stratasys (Nasdaq: SSYS), one of the world’s leading additive manufacturing service bureaus, recently partnered with Lockheed Martin’s Space Systems Company (SSC) to 3D print two large fuel tank simulators for a satellite form, fit and function validation test and process development. With the biggest tank measuring 15 feet long, the project marks one of the largest 3D printed parts RedEye has ever built.
With RedEye’s Fused Deposition Modeling (FDM) technology, the team developed the fuel tanks within a highly condensed time frame and at about half the cost of machining the parts. These rapid prototyping advantages will help Lockheed Martin bring its new design to market faster in a competitive contract bid process.
“With RedEye’s machine capacity and engineering support, we were able to successfully build these tank simulators in a fraction of the time and at a fraction of the cost,” said Andrew Bushell, senior manufacturing engineer at Lockheed Martin Space Systems Company.
The larger tank was built in 10 different pieces and the smaller in 6 different pieces using polycarbonate (PC) material. Combined, the fuel tanks took nearly two weeks to print, taking roughly 150 hours per section. Based on the sheer size of the parts, customized fixtures were required to support the structures as they were bonded together and shipped to be machined to meet specifications. Once all of the pieces were machined, the final assembly required 240 hours.
“This project is unique in two ways – it marks the first aerospace fuel tank simulation produced through additive manufacturing and is one of the largest 3D printed parts ever built,” stated Joel Smith, strategic account manager for aerospace and defense at RedEye. “Our ability to accommodate such a large configuration and adapt to design challenges on the fly, demonstrates that there really is no limit to the problem-solving potential when you manufacture with 3D printing.”
Lockheed Martin first embraced the design benefits of additive manufacturing with RedEye in 2012 and has invested in in-house 3D printers from RedEye’s parent company, Stratasys. RedEye has worked with Lockheed Martin on various tooling and additive manufacturing projects that support its Space Systems Company. The organizations are expected to partner on more 3D printing projects later this year.

Stratasys, Ltd. (Nasdaq: SSYS) announced the debut of "Gemini", a two-part chaise lounge designed by Neri Oxman, Architect, Designer and Professor of Media, Arts and Science at MIT, in collaboration with Professor W. Craig Carter, Department of Materials Science and Engineering of MIT, using Stratasys' Objet500 Connex3 Color Multi-material 3D Printer and CNC milling by Le Laboratoire.
Conveying the relationship of twins in the womb through material properties and their spatial arrangement, Gemini combines both traditional and innovative manufacturing processes and was unveiled at the "Vocal Vibrations" exhibition at La Laboratoire in Paris, France.
The two piece cocoon-like structure combines subtractive and additive manufacturing and continues Oxman's exploration of the Objet500 Connex3 Color Multi-material 3D Printing technology, which enables a variety of material properties and color combinations to be printed in a single build.
"The twin chaise spans multiple scales of the human existence extending from the warmth of the womb to the stretches of the Gemini zodiac in deep space. It recapitulates a human cosmos, our body, like the constellation, drifting in quiet space. Here the duality of nature is expressed through the combination of traditional materials and state of the art 3D printing," says Oxman. "Stratasys new multi- material color 3D printing capability has allowed me to create a rich dialog between sound and light, rigid and flexible, natural and man-made materials and high and low spatial frequencies in ways that were impossible until now".
In a design commission to explore how materials interact with the human body, the twin chaise features an enclosure which cushions the body within a colored, multi-material 3D printed cocoon, replicating the tranquillity of the womb. A solid wood shell house provides the protective exterior. Lining Gemini from the inside are 44 composite PolyJet digital materials, including color. The 3D printed 'skin' uses Stratasys' unique triple jetting technology and combines three base materials: Stratasys' rubber-like TangoPlus, rigid VeroYellow and VeroMagenta, forming varying shades of transparent and opaque yellows and oranges, in different rigidities. The materials, shapes and surfaces of the 3D printed skin enable a unique vibrational acoustic effect for a quiet calming environment.
"Gemini is fundamentally about the complex and contradictory relationship between twins, which is mirrored in the geometrical forms of the two-part chaise and the dualities that drive their formation, such as the combination of natural and synthetic materials," explains Professor Oxman. "The Objet500 Connex3 Color Multi-material 3D Printer and technology enabled us to print 44 material combinations that not only target specific pressure points on the body to form a sensorial landscape, but also act as a soundproof anechoic chamber, an architecture for quieting the mind."'
Gemini features separate, independent parts that together form an enclosure: Gemini Alpha and Gemini Beta. They are inspired by the mythical relationship between the Dioskouri twins, Castor, born of man (named Gemini Beta after the star in the Northern constellation of Gemini) and Pollux born divine (named Gemini Alpha after the second brightest star in the constellation of Gemini).
In keeping with Greek mythology, the first piece, Gemini Alpha recapitulates the form of a swan, as it is believed that Leda, the twins' mother, became pregnant with Pollux after being seduced by Zeus in the disguise of a swan. Inspired by the lingual root of the word 'swan', "sound" or "to sing," Gemini Alpha includes a sound enclosure featuring a range of Stratasys 3D printed PolyJet digital materials with varying elastic and acoustical properties. Surface features that are more curved than others are assigned more elastic properties thereby increasing sound absorption around local chambers.
"I wanted to reproduce the calming and still ambience of the fetus' prenatal experience," explains Professor Oxman. "The 3D printed sound-proof skin brings the whole concept to life, transporting the visitor once seated within the chaise to ultimate serenity."
Gemini Beta, to be unveiled at the Laboratoire Cambridge exhibition in October 2014, is designed to complete its twin, creating a full enclosure, however it can also function as an independent chaise when positioned upside down.
Commenting on Gemini as a key aspect of Vocal Vibrations, David Edwards, founder and director of Le Laboratoire, Paris, says, "We are delighted to be collaborating with Neri Oxman, whose ground-breaking creations continue to wow audiences while demonstrating the dramatic potential of 3D printing within the design world. In fact, this will be the first time that Le Laboratoire has featured a 3D printed piece and we expect the Gemini chaise will prove to be an attention-grabbing aspect of Vocal Vibrations."
"Once again Professor Neri Oxman has demonstrated her ability to push the boundaries of design and manufacturing with the help of Stratasys color multi-material 3D printing," says Arita Mattsoff, Vice President Marketing for Stratasys. "This is a truly unique, functional piece of art that combines traditional manufacturing techniques with cutting edge 3D printing technology. We are seeing more and more designers embrace 3D printing as a powerful new creative tool, enabling them to bring designs they never thought possible to life in a matter of hours."

Motorcyclist Stephen Power was severely injured in an accident near Cardiff, UK. He broke both arms and his right leg was damaged so badly it required a bone graft. Stephen also suffered major injuries to his head and face. He regained consciousness after several months in the hospital.
Consultant maxillofacial surgeon Adrian Sugar explains that a specialist team at the Morriston Hospital in Swansea, UK, successfully dealt with all facial injuries, with the exception of his left cheek and eye socket. The patient’s cheekbone was too far out and his eye was sunk in and dropped. Due to the close proximity of critical and sensitive anatomical structures, the team applied a more accurate expertise approach. This strategy ensured no further damage to his eye in order to maintain his eyesight. The expertise approach entailed the latest 3D computer-aided practices applied by PDR and innovative 3D printing of the titanium implant and fixation plate by LayerWise.
LayerWise manufactured the implant and fixation plate in medical-grade titanium (Ti6Al4V ELI) in accordance with the ISO 13485 standard. “The 3D printing technology mastered by LayerWise is perfectly suited for producing this kind of ultra strong, precise and lightweight titanium implants,” says Peter Mercelis, Managing Director of LayerWise.
“The reconstructive orbital floor plate plays an essential role in the repositioning of the eye in light of the targeted facial symmetry and eye alignment,” explained Romy Ballieux from LayerWise’s Medical Business Unit. “LayerWise produced the floor plate, and polished its upper surface to minimize friction with soft tissues. The floor plate was fixated to the zygomatic bone through the plate’s dedicated slip with attachment holes. The digital 3D printing technology successfully maintained the accuracy of the precise medical imaging data, pre-operative planning and implant design. The 0.1 millimeter (4 mils) geometric accuracy of the floor plate’s freeform surfaces could not be achieved using traditional manufacturing methods.”
Accuracy is even more critical with regard to the fixation plate. This fairly long, slim, curved 3D printed plate requires precise positioning to be able to tie together many fractured bone pieces of the cheek region. A custom-fitting guide was used to fit securely around the anatomy, with slots located to guide the surgeon’s movement when positioning the plate. The fixation plate restored the correct anatomical connection between the frontal, zygomatic and temporal bone. This connection contributed to the successful reconstruction of the patient’s anatomy, providing the best possible facial symmetry.
Ballieux noted: “Dedicated medical engineering specialized in the production aspects of metal 3D printing were key in achieving the impressive facial reconstruction in such a short timespan. The digital process resulted in the 3D printed implant and fixation plate produced in a single manufacturing step in only a couple of hours.”
After his recovery, Stephan Power experiences the results of the surgery as ‘totally life changing’. Instead of using a hat and glasses to mask his injuries, he is now able to do day-to-day things, go and see people, walk in the street, and even go to any public areas. The improved facial symmetry and alignment of his eyes, achieved with the LayerWise implant and fixation plate, clearly made a big difference to the patient. “We are confident that our metal 3D printing technology is capable of improving the quality of life of many more patients,” Ballieux concluded. “The fast-turnaround digital process, from medical imaging up to the finalized 3D printed implants, delivers the required implant geometry and precision to obtain such great facial reconstructions.”
These implants were the result of a close collaboration beween LayerWise specialists and PDR design experts Sean Peel and Dr. Dominic Eggbeer. PDR has a formal collaboration with the Maxillofacial Unit at Morriston Hospital: cartis (Centre for Applied Reconstructive Technologies in Surgery).
LayerWise’s Medical Business Unit aims at providing maximum patient comfort through serial and patient-specific implant manufacturing. The metal Additive Manufacturing (AM) process mastered by LayerWise yields fully anatomic implant shapes offering increased functionality and esthetics as well as improved osseo-integration. LayerWise offers cost-effective manufacturing of orthopedic, cranio-maxillofacial, spinal and dental implants and instruments.
LayerWise also built the world’s first patient-specific lower jaw using metal 3D printing.

Renishaw has collaborated with a leading British bicycle company to create a 3D-printed metal bike frame. Empire Cycles, located in Northwest England, designed the mountain bike to be stronger and lighter, using a process called topological optimization and employing Renishaw’s AM250 additive manufacturing system. The additive process offers design, construction and performance advantages that include: blending complex shapes or hollow structures with internal strengthening features, flexibility to make design improvements right up to the start of production, and the convenience of making one-off parts as easily as batches, which allows for customization. The new titanium alloy frame, about 33% lighter than the original, was manufactured in sections and bonded together.
The two companies originally agreed to optimize and manufacture only the bike’s seat post bracket, but after the part’s successful production, improvement of the whole frame became the new goal. Empire started with a full-size 3D printed replica of its current aluminium alloy bike and the frame was sectioned into parts that could be formed in the AM250’s 12-in. (300-mm) build height. The design was updated with guidance from Renishaw’s applications team and an optimized design – one that eliminates many of the downward facing surfaces that require wasteful support structures – was created using topological optimization.
Topological optimization software programs use iterative steps and finite element analysis to determine the “logical” material placement. Material is removed from areas of low stress until a design optimized for load bearing is created, resulting in a model that is light and strong. Historical challenges in manufacturing these computer-generated shapes are overcome through the additive manufacturing process.
The AM250 uses a high-powered fiber laser to produce fully dense metal parts direct from 3D CAD data. Parts are built layer by layer, in thicknesses ranging from 20 to 100 microns, using a range of fine metal powders melted in a tightly controlled atmosphere. A fully welded vacuum chamber and ultra-low oxygen content in the build atmosphere allow processing of reactive materials, including titanium and aluminum.
The key benefit to Empire Cycles is the performance advantages derived from the additive process. The design has all of the advantages of a pressed steel “monocoque” construction used in motorbikes and cars, without the investment in tooling that would be prohibitive for a small manufacturer. “As no tooling is required, continual design improvements can be made easily, and as the component cost is based on volume and not complexity, some very light parts will be possible at minimal costs,” said Dave Bozich, Business Manager, Renishaw.
The original aluminium alloy seat post bracket is 12 oz. (360 g) and the first iteration of the hollow titanium version is 7 oz. (200 g), a weight savings of 44%. Comparison of the entire frame has the original bike frame weighing in at 4.6 lbs. (2100 g), with the redesigned additive-made frame at only 3.1 lbs. (1400 g), a 33% weight savings. “There are lighter carbon fiber bikes available, but the durability of carbon fiber can’t compare to a metal bike,” said Chris Williams, Managing Director at Empire Cycles. “They are great for road bikes, but when you start chucking yourself down a mountain you risk damaging the frame. We over-engineer our bikes to ensure there are no warranty claims.”
Titanium alloys have more density than aluminium alloys, with relative densities of around .14 lb/in3 (4 g/cm3) and .11 lb/in3 (3 g/cm3), respectively. Therefore, the only way to make a titanium alloy part lighter than its aluminium alloy counterpart is to significantly alter the design and remove any material not contributing to the overall strength of the part. The companies believe further analysis and testing it could result in further weight reduction.
In addition to durability and corrosion-resistance, titanium alloys have a high Ultimate Tensile Strength (UTS) of more than 900 MPa, when processed using additive manufacturing. With near perfect densities – greater than 99.7 percent – the process is better than casting and the small, spherical nature of additive-part porosity has little negative effect on strength. The seat post bracket was tested using the mountain bike standard EN 14766, and it withstood 50,000 cycles of 270 lb ft (1200 N). Testing continued to six times the standard without failure.
Empire is passionate about partnering with top British engineering companies to create elite products. Research into bonding methods resulted in Mouldlife providing the adhesive, which was tested by technical specialists at 3M test facilities. The wheels, drivetrain and components required to finish the bike, were provided by Hope Technology Ltd.
Empire and Renishaw plan to continue testing the completed bicycle frame in the laboratory, using Bureau Veritas UK, and in the field, using portable sensors in partnership with Swansea University. “We plan to develop this further, in partnership, to look at iterative improvements in bonding methods, such as specific surface finishes,” said Bozich. “This project demonstrates that excellent results can be achieved through close customer collaboration.”

With its latest exhibit, "EDAG GENESIS", EDAG offers a visionary outlook for what might well be the next industrial revolution in automotive development and production. Current advances in additive manufacturing now allow a component, module, or even a complete, one-piece vehicle body to be produced in one single production process.
At the EDAG stand in Geneva, the company will be presenting a futuristic vehicle sculpture "EDAG GENESIS". Using the example of a body structure, the sculpture was designed to demonstrate the revolutionary potential of additive manufacturing including bionic lightweight principles, topological optimisation and load-conforming design strategy.
Our exhibit, "EDAG GENESIS" can be seen as a symbol of the new freedoms that additive manufacturing processes will open up to designers and engineers in development and production. Additive manufacturing will make it possible to come a great deal closer to the construction principles and strategies of nature.
"EDAG GENESIS" is based on the bionic patterns of a turtle, which has a shell that provides protection and cushioning and is part of the animal's bony structure. The shell is similar to a sandwich component, with fine, inlying bone structures that give the shell its strength and stability. In "EDAG GENESIS", the skeleton is more of a metaphor; it is there to ensure not mobility, but passenger safety. The framework calls to mind a naturally developed skeletal frame, the form and structure of which should make one thing perfectly clear: these organic structures cannot be built using conventional tools!
The immense potential of additive manufacturing inspired us to define and analyse the current status quo of the latest technologies, and then assess the extent to which it might be possible to use them in vehicle development and production. What process offers the best prospects for being able to produce structural parts with the required product properties in a single production step, without the use of tools?
A multi-disciplinary team of EDAG designers and specialists from the EDAG Competence Centre for Lightweight Construction took a close look at the potential of a number of promising processes, and discussed them with research and industrial experts. Possible candidates for the situation analysis of additive manufacturing were technologies such as selective laser sintering (SLS), selective laser melting (SLM), stereolithography (SLA), and fused deposition modelling (FDM).
In the assessment, a specially developed evaluation matrix was used to quantify the structural relevance of the technologies. How wide is the range of materials that can be used, and what degree of complexity and lot sizes are involved in producing structural parts? The processes were also assessed and classified with regard to part size, tolerance, ecological performance and manufacturing costs.
Apart from SLM, the generative process already industrially available today, with its portfolio of weldable metals and plastics, a refined FDM process also looks to be a promising candidate for the future-oriented subject of additive manufacturing.
Unlike other technologies, FDM makes it possible for components of almost any size to be produced, as there are no pre-determined space requirements to pose any restrictions. Instead, the structures are generated by having robots apply thermoplastic materials. Complex structures are built up layer by layer in an open space - without any tools or fixtures whatsoever.
Metallic SLM aside, most of the high-performance plastics used in additive manufacturing processes do not yet achieve the strength, stiffness and energy absorption values generally required in the industry. This is remedied in the FDM process by the parallel addition of an endless carbon fibre to the production process. One of the central characteristics of FDM is its potential for the incorporation of fibre reinforcements to systematically increase strength and stiffness.
Even though industrial usage of additive manufacturing processing is still in its infancy, the revolutionary advantages with regard to greater freedom in development and tool-free production make this technology a subject for the future. From today's point of view, the production of components, and in the next stage modules, is certainly feasible. As for the target of using additive manufacturing to produce complete vehicle bodies: there is still a long way to go before this becomes an industrial application, so for the time being, it remains a vision.

Solid Concepts has manufactured a 3D printed metal gun using a laser sintering process and powdered metals. The gun, a 1911 classic design, functions beautifully and has already handled 50 rounds of successful firing. It is composed of 33 17-4 Stainless Steel and Inconel 625 components, and decked with a Selective Laser Sintered (SLS) carbon-fiber filled nylon hand grip. The successful production and functionality of the 1911 3D printed metal gun proves the viability of 3D Printing for commercial applications.
“We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D Metal Printing,” says Kent Firestone, Vice President of Additive Manufacturing at Solid Concepts. “And we’re doing this legally. In fact, as far as we know, we’re the only 3D Printing Service Provider with a Federal Firearms License (FFL). Now, if a qualifying customer needs a unique gun part in five days, we can deliver.”
The metal laser sintering process Solid Concepts used to manufacture the 30+ gun components is one of the most accurate additive manufacturing processes available, and more than accurate enough to build the interchangeable and interfacing parts within the 1911 series gun. The gun proves the tight tolerances laser sintering can meet. Plus, 3D Printed Metal has less porosity issues than an investment cast part and better complexities than a machined part. The 3D Printed gun barrel sees chamber pressures above 20,000 psi every time it is fired. Solid Concepts chose to build the 1911 because the design is public domain.
“The whole concept of using a laser sintering process to 3D Print a metal gun revolves around proving the reliability, accuracy and usability of metal 3D Printing as functional prototypes and end use products,” says Firestone. “It’s a common misconception that 3D Printing isn’t accurate or strong enough, and we’re working to change people’s perspective.”
The 3D Printed metal gun proves that 3D Printing isn’t just making trinkets and Yoda heads. The gun manufactured by Solid Concepts debunks the idea that 3D Printing isn’t a viable solution or isn’t ready for mainstream manufacturing. With the right materials and a company that knows how to best program and maintain their machines, 3D printing is accurate, powerful and here to stay.

The horse, dubbed by researchers as ‘Titanium Prints’, had its hooves scanned with a handheld 3D scanner this week. Using 3D modeling software, the scan was used to design the perfect fitting, lightweight racing shoe and four customised shoes were printed within only a few hours.
"3D printing a race horseshoe from titanium is a first for scientists and demonstrates the range of applications the technology can be used for," said John Barnes, Titanium Technologies Theme Leader.
Traditionally made from aluminium, a horseshoe can weigh up to one kilogram but the horse’s trainer, John Moloney, says that the ultimate race shoe should be as lightweight as possible.
“Any extra weight in the horseshoe will slow the horse down. These titanium shoes could take up to half of the weight off a traditional aluminium shoe, which means a horse could travel at new speeds.
“Naturally, we’re very excited at the prospect of improved performance from these shoes,” John Moloney said.
CSIRO’s Titanium expert, John Barnes, said that 3D printing a race horseshoe from titanium is a first for scientists and demonstrates the range of applications the technology can be used for.
“There are so many ways we can use 3D titanium printing. At CSIRO we are helping companies create new applications like biomedical implants and even things like automotive and aerospace parts.
“The possibilities really are endless with this technology,” he said.
The precision scanning process takes just a few minutes and for a horse, shoes can be made to measure each hoof and printed the same day.

A group of engineering students at the University of California, San Diego tested a 3D-printed rocket engine made out of laser sintered metal at the Friends of Amateur Rocketry testing site in the Mojave Desert.
To build the engine, students used a proprietary design that they developed. The engine was primarily financed by NASA’s Marshall Space Flight Center in Huntsville, Alabama and was printed by Illinois-based GPI Prototype and Manufacturing Services using direct metal laser sintering. This is the first time a university has produced a 3D printed liquid fueled metal rocket engine, according to the students, who are members of the UC San Diego chapter of Students for the Exploration and Development of Space.
“We’ve all been working so hard, putting countless hours to ensure that it all works,” said Deepak Atyam, the organization’s president. “If all goes well, we would be the first entity outside of NASA to have tested a liquid fueled rocket motor in its entirety. We hope to see all of our hard work come to fruition.”
The engine was designed to power the third stage of a rocket carrying several NanoSat-style satellites with a mass of less than a few pounds each. The engine is about 6 to 7 inches long and weighs about 10 lbs. It is designed to generate 200 lbs of thrust and is made of cobalt and chromium, a high-grade alloy. It runs on kerosene and liquid oxygen and cost $6,800 to manufacture, including $5,000 from NASA. The rest was raised by students through barbeque sales and other student-run fundraisers.
A 3D printed metal rocket engine would dramatically cut costs for launches, said Forman Williams, a professor of aerospace engineering at the Jacobs School of Engineering at UC San Diego, who is the students’ advisor. Williams admits that he was skeptical at first as the design of liquid-propellant rockets is very complex and detailed, but the students surprised him.

Designer François Brument takes a close look at the possibilities of digital design when it comes to the creation of living spaces. He breaks with traditional approaches to architecture, interior design and furnishings and created separate self-enclosed areas using additive manufacturing. Brument melds these areas into a one unit system including rooms, walls and furniture items.
His carte blanche project titled 'Habitat imprimé' (printed living space), is the result of a collaborative effort with Sonia Laugier. The exhibit on display is a real model of a bedroom with integrated shower and walk-in closet, which visualises the possibilities of additive technologies. The room can be divided as required, shelves can be integrated into walls, surfaces can be structured in any manner desired – the restrictions that formerly set limits to the creativity of builders, architects and designers have been removed.
Looking for a way to turn his vision into reality, Brument contacted voxeljet in May 2011. He was very excited about the technical possibilities offered by 3D printing and after extensive discussions with voxeljet's experts, it was clear that the Augsburg-based company could provide the perfect solution for his project. The visionary was particularly impressed with the large-format VX4000 printer at the voxeljet service centre, which can print very large moulds with a maximum volume of eight cubic metres.
Once the CAD data was forwarded to the service centre, it was time to "print" this unique project. The VX4000 built the entire living space, including furniture, shelving, wash basin and all technical installations, in a total of 64 moulds, which only had to be assembled into a unit.
"As a manufacturer of 3D printers with an attached service centre, our ideas are anything but conventional. Still, we were both surprised and inspired by François Brument's creative approach. The 'Habitat imprimé' project is a milestone for the 3D print technology and drives forward our activities for the development of printing systems for concrete," says voxeljet-CEO Dr. Ingo Ederer.

Global athletic leader New Balance is proud to announce a significant advancement in the use of 3D printing to customize high performance products for athletes. Utilizing a proprietary process, the brand is able to produce spike plates customized to the individual needs and desires of their elite athletes. At the New Balance Games in January 2013, Team New Balance athlete, Jack Bolas, became the first ever track athlete to compete in customized, 3D printed plates.
New Balance has developed a proprietary process for utilizing a runner's individual biomechanical data to create hyper-customized spike plates designed to improve performance. The process requires race simulation biomechanical data which the New Balance Sports Research Lab collects using a force plate, in-shoe sensors and a motion capture system. Advanced algorithms and software are then applied to translate this data into custom 3D printed spike designs.
For the production of the custom plates, New Balance uses selective laser sintering (SLS) to convert powder materials into solid cross-sections, layer by layer using a laser. SLS printing enables the customization process by allowing for complex designs that could not be achieved through traditional manufacturing methods. Additionally, SLS printing greatly accelerates the turnaround time from design to functional part.
"Utilizing our Team New Balance Athletes to develop the customization process was extremely helpful", says Sean Murphy, New Balance's Senior Manager of Innovation and Engineering. "We are impressed with their precise ability to identify and speak to the differences in the custom options provided. They are acutely aware of what is happening in their shoes".
NB Athletes involved in the development of this process included: 2008 and 2012 US Olympic Athlete and current 1500m World Champion gold medalist Jenny Barringer Simpson, 2012 US Olympic Athlete Kim Conley, 2012 Great Britain Olympic Athlete Barbara Parker and 4 time All-American runner in the 800m, 1500m and the Mile Jack Bolas. These athletes provided key feedback in order to develop spike plates that spoke to each individual athlete's personal preference, biomechanics and specific race needs.
In addition to printing semi-rigid parts like spike plates for track runners, New Balance is working on softer SLS printed components that mimic the cushioning properties of foam midsoles. This initiative will be critical to bringing the customization process to a broader audience of athletes .
"With 3D printing we are able to pursue performance customization at a new level to help our elite NB athletes and eventually all athletes. We believe this is the future of performance footwear and we are excited to bring this to consumers," says New Balance President and CEO Robert DeMartini. "As the only major athletic brand to manufacture shoes in the U.S., we are proud to invest in American workers. Developing our printing capabilities could ultimately help us further invest in the American worker by adding highly technical positions to our already skilled labor force in Massachusetts and Maine."
New Balance, headquartered in Boston, MA has the following mission: Demonstrating responsible leadership, we build global brands that athletes are proud to wear, associates are proud to create and communities are proud to host. New Balance is currently the only athletic shoe company that manufactures footwear in the U.S. with 25% of our U.S. footwear shipments produced at five New England facilities. The company also operates a manufacturing facility in Flimby, U.K. New Balance employs more than 4000 associates around the globe, and in 2012 reported worldwide sales of $2.4 billion.

RedEye On Demand, a rapid prototyping and direct digital manufacturing service, and its parent company Stratasys, Ltd. (NASDAQ: SSYS) announced a collaboration with KOR EcoLogic to produce URBEE 2, the first road-ready, fuel-efficient car built using 3D printing, or additive manufacturing, technologies. Targeted to hit the road in two years, URBEE 2 represents a significant milestone in the world of traditional assembly-line manufacturing.
“A future where 3D printers build cars may not be far off after all,” said Jim Bartel, Stratasys vice president of RedEye On Demand. “Jim Kor and his team at KOR EcoLogic had a vision for a more fuel-efficient car that would change how the world approaches manufacturing and today we’re achieving it. URBEE 2 shows the manufacturing world that anything really is possible. There are few design challenges additive manufacturing capabilities can’t solve.”
The KOR EcoLogic team will fully design URBEE 2 in CAD files, sending them to RedEye On Demand for building through Stratasys’ Fused Deposition Modeling (FDM) process. This unique process applies thermoplastics in layers from the bottom up, yielding parts that are durable, precise and repeatable. The finished two-passenger vehicle will comprise 40 large, intricate 3D-printed parts compared to hundreds of parts in the average car. The strong, lightweight vehicle will be designed to go 70 mph on the freeway, using a biofuel like 100 percent ethanol. The goal is for URBEE 2 to drive from San Francisco to New York City on only 10 gallons of fuel, setting a new world record.
“As a mechanical engineer, I’ve always believed we could use technology to help us solve some of society’s greatest challenges, like minimizing our dependence on oil and reducing ozone emissions. How cool is it that American manufacturing can evolve to tackle these challenges head-on? Our team is excited to launch URBEE 2, putting a next-generation vehicle on the road that will eventually be sold to the public,” said Jim Kor, president and senior designer for Winnipeg-based KOR EcoLogic.
URBEE 2, which stands for urban electric, follows in the tracks of its conceptual predecessor, Urbee 1. Produced in 2011 as a partnership between KOR EcoLogic, Stratasys and RedEye On Demand, Urbee 1 proved that 3D printing could in fact produce large, strong parts that meet accurate specifications of a car body. URBEE 2 will take the basic concepts of Urbee 1 to a higher level, including features like a fully functioning heater, windshield wipers and mirrors.
“With the Urbee 1 project, I learned that product design is nearly unencumbered by considerations on how parts can be made with digital manufacturing. That liberation is incredibly powerful and holds a lot of potential for the future of manufacturing,” said Kor.

Physicians at Weill Cornell Medical College and biomedical engineers at Cornell University have succeeded in building a facsimile of a living human ear that looks and acts like a natural ear. Researchers believe their bioengineering method will finally succeed in the long quest by scientists and physicians to provide normal looking "new" ears to thousands of children born with a congenital ear deformity.
In their PLOS ONE study, the researchers demonstrate how 3D printing and new injectable gels made of living cells can be used to fashion ears that are identical to a human ear. Over a three-month period — the length of the study — these flexible ears steadily grew cartilage to replace the collagen that was used to help mold them.
"I believe this will be the novel solution reconstructive surgeons have long wished for to help children born with absence or severe deformity of the ear," says the study’s co-lead author, Dr. Jason Spector, director of the Laboratory for Bioregenerative Medicine and Surgery (LBMS) and associate professor of surgery of plastic surgery in the Department of Surgery at Weill Cornell Medical College and an adjunct associate professor in the Department of Biomedical Engineering at Cornell University. "A bioengineered ear replacement like this would also help individuals who have lost part or all of their external ear in an accident or from cancer."
Currently, replacement ears are constructed using materials that have a Styrofoam-like consistency or, sometimes, surgeons will build ears from rib that is harvested from a young patient. "This surgical option is very challenging and painful for children, and the ears rarely look totally natural or perform well," says Dr. Spector, who is also a plastic and reconstructive surgeon at NewYork-Presbyterian Hospital/Weill Cornell Medical Center. "All other attempts to 'grow’ ears in the lab — including one 1997 study widely publicized by photos of ears implanted on the backs of mice — have failed in the long term."
This Cornell bioengineered ear is the best to date in appearing and acting like a natural ear, the researchers report. Also, the process of making the ears is fast — it takes a week at most.
"This is such a win-win for both medicine and basic science, demonstrating what we can achieve when we work together," says the study’s other lead author, Dr. Lawrence J. Bonassar, associate professor and associate chair of the Department of Biomedical Engineering at Cornell University.
Scanning, Printing and Molding a Human Ear in a Week
The deformity that both Dr. Spector and Dr. Bonassar seek to remedy is microtia, a congenital deformity in which the external ear is not fully developed. Although the causes for this disorder are not entirely understood, research has found that microtia can occur in children whose mothers took an acne medication during pregnancy. Typically, only a single ear is affected.
The incidence of microtia varies from almost one to more than four per 10,000 births each year. Many children born with microtia have an intact inner ear, but experience hearing loss due to the missing external ear structure, which acts to capture and conduct sound.
Dr. Spector and Dr. Bonassar have been collaborating on bioengineered human replacement parts since 2007, and Dr. Bonassar has also been working with other Weill Cornell physicians. For example, he and Weill Cornell’s neurological surgeon Dr. Roger Härtl are currently testing bioengineered disc replacements using some of the same techniques demonstrated in this current study.
The researchers specifically work to develop replacements for human structures that are primarily made of cartilage — joints, trachea, spine, nose — because cartilage does not need to be vascularized with a blood supply in order to survive.
To make the ears, Dr. Bonassar and his colleagues first took a combination laser scan and panoramic photo of an ear from twin girls, which provided a digitized 3D image of their ears on a computer screen. That took 30 seconds, and did not involve any ionizing radiation. The researchers then converted that image into a digitized "solid" ear and used a 3D printer to assemble a mold of the ear. The mold is like a box with a hole in the middle that is in the shape of the mirror image of the ear, say researchers.
They injected animal-derived collagen into that ear mold, and then added nearly 250 million cartilage cells. The collagen served as a scaffold upon which cartilage could grow. Collagen is the main structural protein in the body of every mammal. Animal-based collagen is frequently used for cosmetic and plastic surgery. This high-density collagen gel, which Cornell researchers developed, resembles the consistency of flexible Jell-O when the mold is removed.
"The process is fast," Dr. Bonassar says. "It takes half a day to design the mold, a day or so to print it, 30 minutes to inject the gel and we can remove the ear 15 minutes later. We trim the ear and then let it culture for several days in a nourishing cell culture medium before it is implanted."
During the three-month observation period, the cartilage in the ears grew to replace the collagen scaffold. "Eventually the bioengineered ear contains only auricular cartilage, just like a real ear," says Dr. Spector. Previous bioengineered ears have not been able to maintain their shape or dimensions over time, and the cells within them did not survive.
The researchers are now looking at ways to expand populations of human ear cartilage cells in the laboratory so that these cells can be used in the mold.
Dr. Spector says the best time to implant a bioengineered ear on a child would be when they are about 5- or 6-years-old, because at that age, ears are 80 percent of their adult size. "We don’t know yet if the bioengineered ears would continue to grow to their full size, but I suspect they will," says Dr. Spector. "Surgery to attach the new ear would be straightforward — the malformed ear would be removed and the bioengineered ear would be inserted under a flap of skin at the site."
Dr. Spector says that if all future safety and efficacy tests work out, it might be possible to try the first human implant of a Cornell bioengineered ear in as little as three years.
"The innovation in this study is two-fold," says Dr. Bonassar. "The use of imaging technology to rapid and accurately make the shape of the ear implant is new, as is the high-density collagen gel for the mold."
"These bioengineered ears are highly promising because they precisely mirror the native architecture of the human ear," Dr. Spector says. "They should restore hearing and a normal appearance to children and others in need. This advance represents a very exciting collaboration between physicians and basic scientists. It is a demonstration of what we hope to do together to improve the lives of these patients with ear deformity, missing ears and beyond."

Perez from the Laboratory for Bioregenerative Medicine and Surgery at Weill Cornell Medical College; and Concepcion Kafka, Samantha Popa, Sherry Zhou, Satadru Pramanik, Dr. Bryan N.

CSIRO scientists are using 3D printing to build a new generation of hi-tech fish tags made of titanium. The aim is to use the tags to track big fish such as marlin, tuna, swordfish, trevally and sharks for longer periods.
CSIRO is printing the tags at its Lab 22 facility in Melbourne. The tags are printed overnight and then shipped to Tasmania where marine scientists are trialing them.
Tags are made of titanium for several reasons: the metal is strong, resists the salty corrosiveness of the marine environment, and is biocompatible (non-toxic to living tissues).
One of the advantages of 3D printing is that it enables rapid manufacture of multiple design variations which can then be tested simultaneously. "Using our Arcam 3D printing machine, we've been able to re-design and make a series of modified tags within a week," says John Barnes, who leads CSIRO's research in titanium technologies.
CSIRO's 3D printing facility prints metal items layer by layer out of fused metal powder. Had the scientists been using conventional tags which are machined out of metal blocks, it would have taken a couple of months to design, manufacture and receive the new designs for testing.
"Our early trials showed that the textured surface worked well in improving retention of the tag, but we need to fine-tune the design of the tag tip to make sure that it pierces the fish skin as easily as possible," says John.
"The fast turnaround speeds up the design process – it's very easy to incorporate amendments to designs. 3D printing enables very fast testing of new product designs, which why it's so attractive to manufacturers wanting to trial new products."
Scientists from a number of agencies, including CSIRO Marine and Atmospheric Research, use fish tags to track movements of individual marine species and increase understanding of their behavior. Tracks of selected marine animals tagged by CSIRO and partner agencies can be viewed on the CSIRO Ocean Tracks website.
Medical implants such as dental implants and hip joints are made of biocompatible titanium with a surface texturing which speeds healing and tissue attachment after implantation. Scientists hope that a similar rough surface will help the tag to stay in fish longer.
"A streamlined tag that easily penetrates the fish's skin, but has improved longevity because it integrates with muscle and cartilage, would be of great interest to our colleagues conducting tagging programs across the world," said CSIRO marine researcher, Russell Bradford.
CSIRO's Lab 22 3D printing facility was established in October 2012 and has been used to manufacture a range of prototype products including biomedical implants, automotive, chemical processing and aerospace parts.

Imagine landing on the moon or Mars, putting rocks through a 3-D printer and making something useful – like a needed wrench or replacement part.
"It sounds like science fiction, but now it’s really possible,’’ says Amit Bandyopadhyay, professor in the School of Mechanical and Materials Engineering at Washington State University.
Bandyopadhyay and a group of colleagues recently published a paper in Rapid Prototyping Journal demonstrating how to print parts using materials from the moon.
Approached by NASA
Bandyopadhyay and Susmita Bose, professor in the School of Mechanical and Materials Engineering, are well known researchers in the area of three-dimensional printing for creation of bone-like materials for orthopedic implants.
In 2010, researchers from NASA initiated discussion with Bandyopadhyay, asking if the research team might be able to print 3-D objects from moon rock.
Because of the tremendous expense of space travel, researchers strive to limit what space ships have to carry. Establishment of a lunar or Martian outpost would require using the materials that are on hand for construction or repairs. That’s where the 3-D fabrication technology might come in.
Three-dimensional fabrication technology, also known as additive manufacturing, allows researchers to produce complex 3-D objects directly from computer-aided design (CAD) models, printing the material layer by layer. In this case, the material is heated using a laser to high temperatures and prints out like melting candle wax to a desired shape.
Simple shapes built
To test the idea, NASA researchers provided Bandyopadhyay and Bose with 10 pounds of raw lunar regolith simulant, an imitation moon rock that is used for research purposes.
The WSU researchers were concerned about how the moon rock material - which is made of silicon, aluminum, calcium, iron and magnesium oxides - would melt. But they found it behaved similarly to silica, and they built a few simple shapes.
The researchers are the first to demonstrate the ability to fabricate parts using the moon-like material. They sent their pieces to NASA.
"It doesn’t look fantastic, but you can make something out of it,’’ says Bandyopadhyay.
Tailoring composition, geometry
Using additive manufacturing, the material could also be tailored, the researchers say. If you want a stronger building material, for instance, you could perhaps use some moon rock with earth-based additives.
"The advantage of additive manufacturing is that you can control the composition as well as the geometry,’’ says Bose.
In the future, the researchers hope to show that the lunar material could be used to do remote repairs.
"It is an exciting science fiction story, but maybe we’ll hear about it in the next few years,’’ says Bandyopadhyay. "As long as you can have additive manufacturing set up, you may be able to scoop up and print whatever you want. It’s not that far-fetched.’’
The research was supported by a $750,000 W.M. Keck Foundation grant.

Innovative 3D printing technology from Augsburg-based voxeljet is on display in the newest James Bond film Skyfall – more specifically in the scene when James Bond's car explodes in flames. A total of three Aston Martin DB 5 models were created at the company's service centre. The models double for the now priceless original vehicle from the 1960s in the film's action scenes.
Action scenes in expensive film productions such as a James Bond film must look as realistic as possible. For the model builders working behind the scenes, the high demands of film makers translate into more requirements and detail work. Therefore companies such as Propshop Modelmakers Ltd., which specialises in the production of film props, are always on the look-out for trend-setting manufacturing methods.
The fact that the British company selected the 3D printing technology of a German provider is a special honour for the Augsburg company. "Of course only state-of-the-art technology was used for the new James Bond film Skyfall. To be considered a benchmark by the model builders from the Pinewood Studios is evidence of the performance and position of our 3D printing system in terms of global ranking," says voxeljet CEO Dr. Ingo Ederer.
voxeljet is considered a pioneer in the area of 3D printing. At its service centre, which is the largest in Europe, the Augsburg-based company has specialised in the on-demand production of sand moulds for metal casting, as well as plastic moulds and 3D functional moulds. Small-batch and prototype manufacturers in a variety of branches of European industry appreciate the fast and cost-effective manufacture of their casting moulds and 3D models based on CAD data. At the same time, the internationally active company has also made a name for itself as a manufacturer of high-resolution 3D printing systems. voxeljet moulds are very precise and rich in detail – properties that also impressed the British model builders.
Aston Martin from a 3D printer
"Propshop commissioned us to build three plastic models of the Aston Martin DB5. We could have easily printed the legendary sports car in one piece at a scale of 1:3 using our high-end VX4000 printer, which can build moulds and models in dimensions of up to eight cubic metres. But the British model builders were pursuing a different approach. To ensure that the Aston Martin was as true to detail as possible, and for the purpose of integrating numerous functions into the film models, they decided on an assembly consisting of a total of 18 individual components. The entire body is based on a steel frame, almost identical to how vehicles were assembled in the past," says Ederer.
voxeljet started the printing process once the CAD data for all components were available. The models are produced with the layer-wise application of particle material that is glued together with a binding agent. The plastic material PMMA is used for this purpose; it is ideally suited for precisely these types of tasks. The individual components that are made of PMMA feature outstanding attention to detail, but are also very stable and resilient, which means that they are well suited for mechanical post-processing.
Following the unpacking process, which involves the removal of unbound material from the finished components, voxeljet's service centre looked very much like a body shop. A total of 54 individual parts for the three vehicle models, including mudguards, doors, bonnets, roofs and more, now had to be safely packaged and transported to Pinewood Studios near London.
Elaborate detailed work
The model builders at Propshop then meticulously assembled and finished the components, painted them in the original colour and added chrome applications along with realistic-looking bullet holes. The special effects that can be seen in Skyfall confirm the perfection in execution of this work. After the finishing process, it is impossible to distinguish the Aston Martin models made with the voxeljet printer from the original, even in the close-up shots. And: The priceless Aston Martin DB5, which was already used in the first James Bond film exactly 50 years ago, remains unscathed, while one of the elaborately and meticulously constructed models explodes in flames in the film. An expensive crash, since one of the three models was auctioned off by Christie's for almost USD 100,000.
For voxeljet, participating in a James Bond production was of course anything but a normal contract, and it also opened up an entirely new industry for the company: "In addition to the automotive industry, foundries, designers and artists, the film industry represents an entirely new customer base for voxeljet. 3D printing is on the cusp of a great future in the film industry. The technology offers fantastic opportunities, since it is usually much faster, more precise and more economical than classic model construction," says Ederer.
voxeljet specialises in 3D print technology. This globally operating high-tech company is a well-respected manufacturer of 3D print systems that are suitable for industrial applications. At the same time, the company operates one of Europe's largest service centres for the "on-demand production" of moulds and models for metal casting.

Around the Rochester Institute of Technology (RIT) campus, professor Denis Cormier’s reputation has earned his rapid prototyping course a wait list. Industrial, mechanical and manufacturing engineering students line up in hopes that they will be included in the discussion of 3D-printing technologies.
With all the buzz 3D printing has earned recently, students are increasingly aware of it, and they want to understand what is possible and how they can use the technology. Joe Noble, a mechanical engineering undergraduate, said, “I knew that 3D printers existed, but I didn’t have a lot of knowledge about them.”
Cormier changes that. “Because of this course, we now have the exposure to advanced and innovative techniques that we could use in the future,” said Jeet S. Mehta, a graduate student pursing a master’s of science in mechanical engineering.
In one quarter, Cormier introduces students to the processes, materials, capabilities and limitations of a broad range of 3D-printing technologies. He concludes with a description of what is on the horizon. Betsy Khol, an undergraduate in the industrial engineering program, said, “At the end of the quarter, the course was all about where we could take 3D printing and where the technology was going, which was really exciting.”
The course challenges students to put their new-found knowledge into practice. “Our assignment was to design, build and play a musical instrument,” said Noble. He and teammates Mehta and Khol created a ukulele and built it on a Dimension 3D Printer. “The ukulele was a practical decision; we could tune it.”
But that simple idea morphed into something more. “We had a unique opportunity to take advantage of what the 3D printer could do. So we incorporated a 3D, color version of the RIT tiger,” said Khol.
Although they had options for automated color 3D printing, the team devised a series of interventions to make its Dimension 3D Printer build a multicolored instrument. According to Mehta, “The key reason for selecting the Dimension machine for printing our part was the plastic material that it uses. Since we had to play the instrument, the strength and integrity of the part was very important.”
With one small prompt from Cormier, the team got creative. “When Dr. Cormier informed us that we could pause a build and swap material cartridges to change colors, that’s when everything came together. Now we could print the ukulele in one go without having to assemble different pieces,” said Mehta.
According to Noble, the process was quite easy. “We designed the tiger face to have an even number of layers for each color. In the Catalyst setup program, we oriented the ukulele with the tiger facing down. Then all we had to do is insert pauses between the layers where there was a color change.”
At the Dimension printer, the team waited 20 minutes for the first color to complete then swapped material cartridges and repeated that for the remaining colors. After that, they left for the day and had a 3D printed ukulele waiting for them when they returned to class. After soaking the ukulele to remove support structures, the team attached the mounting pegs, added strings and tuned it for their big debut.
The final test was a humble, eight-note rendition of “Jingle Bells.” For their work and innovation, Cormier gave them an A. He said, “When fellow students and guests heard Joe playing the team’s 3D-printed ukulele, there were plenty of grins and ‘cool’ comments throughout the auditorium.”
According to Noble, “It was one of my favorite classes that I’ve taken at RIT. I now have a whole other dimension to the possibilities of prototyping. It is a very intriguing field. If I ended up working in it — in the actual development of the processes — I’d be stoked.”
When University of Virginia engineering students posted a YouTube video last spring of a plastic turbofan engine they had designed and built using 3-D printing technology, they didn’t expect it to lead to anything except some page views.
But executives at The MITRE Corporation, a McLean-based federally funded research and development center with an office in Charlottesville, saw the video and sent an announcement to the School of Engineering and Applied Science that they were looking for two summer interns to work on a new project involving 3-D printing. They just didn’t say what the project was.
Only one student responded to the job announcement: Steven Easter, then a third-year mechanical engineering major.
“I was curious about what they had to offer, but I didn’t call them until the day of the application deadline,” Easter said.
He got a last-minute interview and brought with him his brother and lab partner, Jonathan Turman, also a third-year mechanical engineering major.
They got the job: to build over the summer an unmanned aerial vehicle, using 3-D printing technology. In other words, a plastic plane, to be designed, fabricated, built and test-flown between May and August. A real-world engineering challenge, and part of a Department of the Army project to study the feasibility of using such planes.
Three-dimensional printing is, as the name implies, the production or “printing” of actual objects, such as parts for a small airplane, by using a machine that traces out layers of melted plastic in specific shapes until it builds up a piece exactly according to the size and dimensions specified in a computer-aided drawing produced by an engineer.
In this case, the engineers were Easter and Turman, working with insight from their adviser, mechanical and aerospace engineering professor David Sheffler, a U.Va. Engineering School alumnus and 20-year veteran of the aerospace industry.
It was a daunting project – producing a plane with a 6.5-foot wingspan, made from assembled “printed” parts. The students sometimes put in 80-hour workweeks, with many long nights in the lab.
“It was sort of a seat-of-the-pants thing at first – wham, bang,” Easter said. “But we kept banging away and became more confident as we kept designing and printing out new parts.”
Sheffler said he had confidence in them “the entire way.”
The way eventually led to assembly of the plane and four test flights in August and early September at Milton Airfield near Keswick. It achieved a cruising speed of 45 mph and is only the third 3-D printed plane known to have been built and flown.
During the first test, the plane’s nosepiece was damaged while the plane taxied around the field.
“We dogged it,” Easter said. “But we printed a new nose.”
That ability to make and modify new parts is the beauty of 3-D printing, said Sheffler, who works with students in the Engineering School’s Rapid Prototyping Lab. The lab includes seven 3-D printers used as real-world teaching tools.
“Rapid prototyping means rapid in small quantities,” Sheffler said. “It’s fluid, in that it allows students to evolve their parts and make changes as they go – design a piece, print it, make needed modifications to the design, and print a new piece. They can do this until they have exactly what they want.”
The technology also allows students to take on complex design projects that previously were impractical.
“To make a plastic turbofan engine to scale five years ago would have taken two years, at a cost of about $250,000,” Sheffler said. “But with 3-D printing we designed and built it in four months for about $2,000. This opens up an arena of teaching that was not available before. It allows us to train engineers for the real challenges they will face in industry.”
MITRE Corp. representatives and Army officials observed the fourth flight of Easter and Turman’s plane. They were impressed and asked the students to stay on through this academic year as part-time interns. Their task now is to build an improved plane – lighter, stronger, faster and more easily assembled. The project also is their fourth-year thesis.
“This has been a great opportunity for us,” Easter said, “to showcase engineering at U.Va. and the capabilities of the Rapid Prototyping Lab.”

Award-winning water pump and heating system manufacturer, Whale, today announced an increase in new business following the purchase of an Objet Connex multi-material 3D Printer for its headquarters in Bangor, Northern Ireland. The introduction of Objet Connex multi-material technology means the company can now prototype design concepts with supreme accuracy and undertake robust testing using watertight digital materials - helping the company to bring its products to market quicker than ever before.
"We saw Objet Connex multi-material technology as a means to provide a broad capability," comments Richard Bovill, Whale Design Engineering Manager. "The range of materials from rigid to rubber gives us a great advantage when recreating production parts, especially the water tight material, as it allows us to carry out robust tests that can reduce the product development process by weeks or even months."
Over the past three years Whale has issued 15 worldwide design patents, driven by its culture of innovation throughout the business, supplying first class products to the marine, caravan and motorhome, shower drainage and industrial markets. To maintain its leadership in these markets, Whale added an Objet Connex 3D Printer to its portfolio of rapid prototyping solutions to expand its capabilities when designing new products and making improvements to current solutions.
"Using Objet Connex multi-material technology we can now produce rubber, over-molded, transparent and waterproof models, allowing us to recreate design faults and identify ways we can improve our products in a much more cost effective and timely manner," says Managing Director Patrick Hurst. "This has enabled us to increase our existing business and create new business opportunities, whilst maintaining the level of innovation our customers are accustomed to."
With the Objet Connex multi-material 3D Printer currently in operation 24 hours a day, Whale are using a large variety of materials to deal with the demand and diversity of its customer's design projects.
"Having such a wide range of shore hardness and the ability to print rubber parts, means that it is like having three machines in one. We can now deliver our customers a finished high quality model in as little as 24 hours," concludes Hurst.
Whale purchased the Objet Connex 3D Printer through Objet UK distributor HK Rapidprototyping. Nigel Bunt, Sales Director at HK Rapidprototyping, adds: "The Objet Connex provided Whale the ideal solution for their product design projects. Whale has now become more flexible and thus increased its workflow capacity."

Objects created using 3-D printing have a common flaw: They are fragile and often fall apart or lose their shape.
"I have an entire zoo of broken 3-D printed objects in my office," said Bedrich Benes, an associate professor of computer graphics at Purdue University.
The printed fabrications often fail at points of high stress.
"You can go online, create something using a 3-D printer and pay $300, only to find that it isn't strong enough to survive shipping and arrives in more than one piece," said Radomir Mech, senior research manager from Adobe's Advanced Technology Labs.
The 3-D printers create shapes layer-by-layer out of various materials, including metals and plastic polymers. Whereas industry has used 3-D printing in rapid prototyping for about 15 years, recent innovations have made the technology practical for broader applications, he said.
"Now 3-D printing is everywhere," Benes said. "Imagine you are a hobbyist and you have a vintage train model. Parts are no longer being manufactured, but their specifications can be downloaded from the Internet and you can generate them using a 3-D printer."
The recent rise in 3-D printing popularity has been fueled by a boom in computer graphics and a dramatic reduction of the cost of 3-D printers, Benes said.
Researchers at Purdue and Adobe's Advanced Technology Labs have jointly developed a program that automatically imparts strength to objects before they are printed.
"It runs a structural analysis, finds the problematic part and then automatically picks one of the three possible solutions," Benes said.
Findings were detailed in a paper presented during the SIGGRAPH 2012 conference in August. Former Purdue doctoral student Ondrej Stava created the software application, which automatically strengthens objects either by increasing the thickness of key structural elements or by adding struts. The tool also uses a third option, reducing the stress on structural elements by hollowing out overweight elements.
"We not only make the objects structurally better, but we also make them much more inexpensive," Mech said. "We have demonstrated a weight and cost savings of 80 percent."
The new tool automatically identifies "grip positions" where a person is likely to grasp the object. A "lightweight structural analysis solver" analyzes the object using a mesh-based simulation. It requires less computing power than traditional finite-element modeling tools, which are used in high-precision work such as designing jet engine turbine blades.
"The 3-D printing doesn't have to be so precise, so we developed our own structural analysis program that doesn't pay significant attention to really high precision," Benes said.
The paper was authored by Stava, now a computer scientist at Adobe, doctoral student Juraj Vanek; Benes; Mech; and Nathan Carr, a principal scientist at Adobe's Advanced Technology Labs.
Future research may focus on better understanding how structural strength is influenced by the layered nature of 3-D-printed objects. The researchers may also expand their algorithms to include printed models that have moving parts.

A 7,000 year old technique, known as Egyptian Paste (also known as Faience), could offer a potential process and material for use in the latest 3D printing techniques of ceramics, according to researchers at UWE Bristol.
Professor Stephen Hoskins, Director of UWE's Centre for Fine Print Research and David Huson, Research Fellow, have received funding from the Arts and Humanities Research Council (AHRC to undertake a major investigation into a self-glazing 3D printed ceramic, inspired by ancient Egyptian Faience ceramic techniques. The process they aim to develop would enable ceramic artists, designers and craftspeople to print 3D objects in a ceramic material which can be glazed and vitrified in one firing.
The researchers believe that it possible to create a contemporary 3D printable, once-fired, self-glazing, non-plastic ceramic material that exhibits the characteristics and quality of Egyptian Faience.
Faience was first used in the 5th Millennium BC and was the first glazed ceramic material invented by man. Faience was not made from clay (but instead composed of quartz and alkali fluxes) and is distinct from Italian Faience or Majolica, which is a tin, glazed earthenware. (The earliest Faience is invariably blue or green, exhibiting the full range of shades between them, and the colouring material was usually copper). It is the self-glazing properties of Faience that are of interest for this research project.
Current research in the field of 3D printing concentrates on creating functional materials to form physical models. The materials currently used in the 3D printing process, in which layers are added to build up a 3D form, are commonly: UV polymer resins, hot melted 'abs' plastic and inkjet binder or laser sintered, powder materials. These techniques have previously been known as rapid prototyping (RP). With the advent of better materials and equipment some RP of real materials is now possible. These processes are increasingly being referred to as solid 'free-form fabrication' (SFF) or additive layer manufacture. The UWE research team have focused previously on producing a functional, printable clay body.
This three-year research project will investigate three methods of glazing used by the ancient Egyptians: 'application glazing', similar to modern glazing methods; 'efflorescent glazing' which uses water-soluble salts; and 'cementation glazing', a technique where the object is buried in a glazing powder in a protective casing, then fired.These techniques will be used as a basis for developing contemporary printable alternatives
Professor Hoskins explains, “It is fascinating to think that some of these ancient processes, in fact the very first glazed ceramics ever created by humans, could have relevance to the advanced printing technology of today. We hope to create a self-glazing 3D printed ceramic which only requires one firing from conception to completion rather than the usual two. This would be a radical step-forward in the development of 3D printing technologies. As part of the project we will undertake case studies of craft, design and fine art practitioners to contribute to the project, so that our work reflects the knowledge and understanding of artists and reflects the way in which artists work.”
The project includes funding for a three-year full-time PhD bursary to research a further method used by the Egyptians, investigating coloured 'frit', a substance used in glazing and enamels. This student will research this method, investigating the use of coloured frits and oxides to try and create as full a colour range as possible. Once developed, this body will be used to create a ceramic extrusion paste that can be printed with a low-cost 3D printer. A programme of work will be undertaken to determine the best rates of deposition, the inclusion of flocculants and methods of drying through heat whilst printing.
This project offers the theoretical possibility of a printed, single fired, glazed ceramic object - something that is impossible with current technology.

How fast can 3D Printing (and stereolithography in particular) go? The answer, according to the 2012 Formula Group T team, is - more than 140 km/h!
Competing in the prestigious Formula Student 2012 challenge, a 16-man strong team of next-generation engineers from Group T have unveiled the world’s first race car created in great part through 3D Printing: the Areion. Named after the divinely-bred, extremely swift, immortal horse of Greek mythology, the Areion is a powerhouse of innovation and green technology. On July 31st, it lived up to its name on the Hockenheim race circuit by going from zero to 100km/h in just 4 seconds and achieving a top speed of 141km/h on the track. Cutting-edge technologies incorporated into their eco-friendly race car included an electric drive train, bio-composite materials, and of course, Additive Manufacturing (3D Printing) on a grand scale with Materialise.
Big Ideas Brought to Life with Mammoth Technology
Using Materialise’s appropriately named Mammoth stereolithography machines it is possible to manufacture parts of up to 2100x680x800mm. With a build envelope that massive, the Formula Group T team recognized the possibility to not only print the entire body of the car, but to also integrate some unique features directly into the design. Therefore, working in close collaboration with engineers at Materialise, this is exactly what they achieved: going from initial shell design to a fully finished 3D Printed car body in just three weeks.
The Greatest Shell in Racing since Mario Kart
Starting from Formula Group T’s design for the outer shell, engineers at Materialise quickly got to work. Within a week, Materialise engineers had applied their experience from other projects to the creation of an intelligent 3D Printed car body with integrated clips and connection points. This allows for the easy assembly of the shell and therefore, faster access to the inner workings of the car when maintenance is needed.
Like a Shark through Water
Printed directly onto the nose of the race car is a shark skin texture, similar to that found on high-tech competition swimsuits. As with the swimsuits, the aim of the teeth-like ridges is to reduce drag, increase thrust, and improve performance on race day. Whether or not the texture helped the Areion cut through the air is still to be determined, but one thing is for sure – the shark skin made the nose of the car look great!
The Coolest Side Pods on the Track
Both the right and left side pods were designed and printed with complex cooling channels. Printed into the left side pod are a nozzle behind the radiator and a diffuser, which optimize cooling by creating the ideal flow of air through the radiator. A fan is installed behind the radiator in order to do this even at low speeds and while the car is stationary. In the right side pod, complex channels were developed and printed to create a cyclone effect that removes water and dirt from the air before it enters the engine compartment.
The Results are in
With two races completed, the Formula Group T team is already the proud winner of two awards and an impressive ranking for a first-time team in the competition. While in the UK at the Silverstone racing circuit, the team was honored with the Best Teamwork Award by Airbus and Koen Huybrechts, who was responsible for the drivetrain, won the Craig Dawson most valuable team member award. While in Germany on the Hockenheim racing circuit, the team finished in a well-deserved 11th position and found themselves among other top teams in this international competition.

Aurora Flight Sciences' 3D wing, designed by Aurora and built with additive manufacturing technology developed by Stratasys Inc., was showcased at the announcement of the new National Additive Manufacturing Innovation Institute (NAMII) by senior officials of the Obama administration.
The announcement of the new manufacturing technology center was made by Frank Kendall, Under Secretary of Defense for Acquisition and Technology along with Rebecca Blank, Acting Secretary of Commerce and Gene Sperling, Director of the National Economic Council and Assistant to the President for Economic Policy, on August 16 in Youngstown, Ohio. The event was also attended by United States Senator Sherrod Brown and United States Congressman Tim Ryan of Ohio.
Aurora Flight Sciences and Stratasys fabricated and flew a 62-inch wingspan aircraft with a wing composed entirely of additive manufactured components. The wing was designed by Aurora and manufactured by Stratasys utilizing their Fused Deposition Modeling (FDM®) 3D printers.
The Stratasys FDM printer fabricated Aurora's wing using a 3D design model, by depositing layers of high-performance thermoplastic material. This manufacturing approach reduces some of the design constraints engineers face when using traditional fabrication techniques. FDM offers unparalleled capabilities for rapid prototyping of small aerospace structures.
The design of the wing's structure was optimized to reduce weight while maintaining strength. "The success of this wing has shown that 3D printing can be used to rapidly fabricate the structure of a small airplane," said Dan Campbell, Structures Research Engineer at Aurora. "If a wing replacement is necessary, we simply click print and within a couple days we have a new wing ready to fly."
Aurora and Stratasys will continue to work together to develop additive manufacturing for aerospace applications. "In the aerospace industry, additive manufacturing has the benefits of reducing material usage, doing away with tooling, reducing part count, and simplifying assembly," said Bill Macy, Application Development Lead at Stratasys. "These benefits allow the manufacture of a low quantity of products at lower cost, in less time, with competitive performance."
Aurora Flight Sciences designs and builds aerospace vehicles for commercial and military applications. Aurora is headquartered in Manassas, VA and operates production facilities in Bridgeport, WV and Columbus, MS as well as a Research and Development Center in Cambridge, MA.

Protos, a San Francisco-based company, launched its first collection of 3D printed sunglasses. In a region abundant with software tech magnates, they've proven technology can also be used to make ground-breaking eyewear.
Protos offers designs that can only be made by leveraging the most cutting edge software and 3D printing technology. Though many have claimed to do so, they are one of only a small handful of companies that have created something refined enough to truly be sold as a usable, lasting product. Each pair of sunglasses purchased from Protos is produced via laser sintering, which builds each frame layer by layer of material. The properties of this intricate layering process are leveraged to result in bold and striking designs that are unachievable through standard manufacturing methods.
This first collection showcases the realm of possibilities with 3D printing. The debut line includes the Hal Pixel, which has gained praise and recognition from the industrial design community.
"Protos Eyewear [is] a radically different approach to eyewear that opens the frontiers to limitless fun," says Phnam Bagley, Founder and Design Director at Eternal Luxe. Protos will soon offer custom eyewear with a tailored fit based on an individual's facial measurements and dimensions.

University of Washington mechanical engineering students braved uncharted waters as they paddled to the finish line at the annual Milk Carton Derby at Green Lake in Seattle in what they believe is the world’s first boat made using a 3-D printer.
The new UW student club Washington Open Object Fabricators (or WOOF) built the boat as its inaugural project. The club’s blog describes the undergraduate members’ 10-week quest to make equipment and develop techniques to be first to print a seaworthy craft.
Judges weren’t sure how to qualify the UW entry, which used recycled milk cartons for its buoyancy but not quite in the way that contest organizers had envisioned. In the end, the boat raced as an unofficial entry in the adult open category, where it placed second.
Faculty adviser Mark Ganter, professor of mechanical engineering, experiments with unconventional methods and ingredients for 3-D printing (including ceramics, glass and cookie dough) in the UW’s Open3DP Lab, which he operates with colleague Duane Storti, associate professor of mechanical engineering.
Printing a boat “is a historic first,” Ganter said. Two other UW groups have tried and failed at the same task, he added, and making it out of recycled milk jugs is an added challenge.
“Frankly, milk jug material is an awful material to work with,” he said. “It shrinks, it curls, it doesn’t want to stick to itself. Overcoming all those parts of the problem was part of the achievement.”
Ganter teaches a course in Computer-Aided Technology that uses his lab’s 3-D printers. The student club was formed in the spring by Bethany Weeks, club manager; Matt Rogge, club president; and Adam Commons, vice-president. It has now grown to about 20 active members.
Some experts predict 3-D printers will revolutionize manufacturing by allowing people to buy a design online and then immediately print out a physical object. The process takes instructions from a computer to print a solid object in layers, using a machine similar to an inkjet printer. High-end machines have long been used in manufacturing, but lower-cost versions are increasingly being used by hobbyists and educational groups.
The UW club hopes to continue printing using recycled materials, building large-scale printers and developing low-cost 3-D printing techniques.
“I hope that the club gets printers in the hands of as many students as possible,” Rogge said. “People are intimidated because they think 3-D printing is complicated, or expensive, and it really doesn’t have to be.”
Photos were taken by club co-founder and manager Bethany Weeks.

The moment Megan Lavelle saw the device, she knew it would change her daughter’s life. Lavelle is an energetic, unstoppable mom whose youngest daughter, Emma, was born with arthrogryposis multiplex congenita (AMC). At a Philadelphia conference for AMC families, Lavelle learned about the Wilmington Robotic Exoskeleton (WREX), an assistive device made of hinged metal bars and resistance bands. It enables kids with underdeveloped arms to play, feed themselves and hug.
AMC is a non-progressive condition that causes stiff joints and very underdeveloped muscles. Emma was born with her legs folded up by her ears, her shoulders turned in. “She could only move her thumb,” says Lavelle. Doctors immediately performed surgery and casted Emma’s legs. The baby girl went home with parents determined to provide the best care.
Medical experts warned that AMC would prevent Emma from ever experiencing any sort of normalcy. She developed more slowly than an average child and spent much of her first two years in casts or undergoing surgery. Unable to see Emma play and interact with her environment in ways her older daughter had, Lavelle privately wondered whether Emma’s cognitive ability would be hampered as well.
Determined to Grow
But Emma progressed, slow and steady. As she grew and became able to move about with the help of a walker, it became clear that her mind was sharp and her determination on par with her mom’s. At two years old, she still couldn’t lift her arms, and the smart little girl wanted more. “She would get really frustrated when she couldn’t play with things like blocks,” Lavelle says. And so the mom would be Emma’s arms for her; playing with blocks, eating, brushing teeth.
Then came the WREX, demonstrated at the conference by an 8-year-old AMC patient lifting his arms and moving them in all directions. Lavelle met with the presenters, Tariq Rahman, Ph.D, head of pediatric engineering and research, and Whitney Sample, research designer, both from Nemours/Alfred I. duPont Hospital for Children in Wilmington, Delaware. Rahman and Sample had worked for years to make the device progressively smaller, serving younger and younger patients. Attached to a wheelchair, the WREX worked for kids as young as six. But Emma was two, small for her age, and free to walk.
In Sample’s tool-and-toy filled workshop, the team strapped Emma’s little arms into a small but awkward trial WREX attached to a stationary support. “She just started throwing her hands around and playing,” Sample says. Megan brought Emma candy and toys and watched her lift her arms toward her mouth for the first time.
For Emma to wear the WREX outside the workshop, Rahman and Sample needed to scale it down in size and weight. The parts would be too small and detailed for the workshop’s CNC system to fabricate. But humming along near Sample’s desk was a Stratasys 3D Printer, which can build complex objects automatically from computer designs — like an inkjet printer but in three dimensions. Sample often used it to work out ideas with physical models, so he 3D printed a prototype WREX in ABS plastic. The difference in weight allowed Sample to attach the Emma-sized WREX to a little plastic vest.
The 3D-printed WREX turned out to be durable enough for everyday use. Emma wears it at home, at preschool, and during occupational therapy. And the design flexibility of 3D printing lets Sample continually improve upon the assistive device, working out ideas in CAD and building them the same day.
Fifteen kids now use custom 3D-printed WREX devices. For these littlest patients, Rahman explains, the benefits may extend beyond the obvious. Prolonged disuse of the arms can sometimes condition children to limited development, affecting cognitive and emotional growth. Doctors and therapists are watching Emma closely for the benefits of earlier arm use.
Emma quickly grew to love the abilities WREX unlocked in her. “When she started to express herself, we would go upstairs [to Sample’s workshop] and we would say, ‘Emma, you know we’re going to put the WREX on.’ And she called them her magic arms,” Lavelle says.
The little girl’s approval is a fitting reward for her determined mom and dedicated researchers. Sample says: “To be a part of that little special moment for someone else, can’t help but tug at your heart strings.”
It is 2.30 metres high, 50 centimetres wide, weighs almost 20 kilograms and is the largest spoon that WMF has ever produced. Both its purpose and its manufacture, in which 3D printing plays a central role, are anything but normal.
Of course the giant specimen is not meant for conventional use but rather has been designed to highlight an optical phenomenon that anyone who has experienced the reflections and optical distortions of looking into a polished bowl of a spoon (the concave front of a spoon) would be familiar with. People interested in an explanation for this special optical feature will want to check out the "Viseum", the museum for optics and precision mechanics in Wetzlar. This is where the EUR 10,000 WMF exhibit can be found, and it demonstrates the origin behind these reflections in XL format, so to speak.
Just as impressive as the spoon itself is the process of how it was made, most of which took place at the WMF model building studio in Geislingen. "While the manufacture of single oversize cutlery pieces is not unusual, we have never made anything of this size to date. However, not least due to 3D print technology, this project was completed quickly and without any problems", says Gerd Greiner, manager of the model building studio.
The well-known "Palma" WMF cutlery served as a template for the giant spoon. As part of a first step, the CAD data of the original Palma spoon was adjusted to the required size on the computer. This data was then transferred to the voxeljet service centre, where a high-performance printer using the 3D printing method produced a plastic model of the bowl of the spoon, which was used as the original model. This process did away with the elaborate construction of a negative mould, resulting in significant cost and time savings. The printed PMMA model, which impressed with a high degree of mechanical stability and attention to detail, was used to quickly generate a sand mould that was cast in bronze. Subsequently the bowl was finished and coated with nickel, and finally attached to the spoon handle, which was made of brass and also coated with nickel. "The WMF spoon is another successful example of the ever increasing popularity of 3D printing beyond conventional application areas. We are really impressed with the creativity shown by users in applying 3D technology, which is still a fairly young method", says Rudolf Franz, COO of voxeljet technology GmbH.

A group of graphics experts led by computer scientists at Harvard have created an add-on software tool that translates video game characters—or any other three-dimensional animations—into fully articulated action figures, with the help of a 3D printer.
The project is described in detail in the Association for Computing Machinery (ACM) Transactions on Graphics and will be presented at the ACM SIGGRAPH conference on August 7.
Besides its obvious consumer appeal, the tool constitutes a remarkable piece of code and an unusual conceptual exploration of the virtual and physical worlds.
"In animation you're not necessarily trying to model the physical world perfectly; the model only has to be good enough to convince your eye," explains lead author Moritz Bächer, a graduate student in computer science at Harvard School of Engineering and Applied Sciences (SEAS). "In a virtual world, you have all this freedom that you don't have in the physical world. You can make a character so anatomically skewed that it would never be able to stand up in real life, and you can make deformations that aren't physically possible. You could even have a head that isn't attached to its body, or legs that occasionally intersect each other instead of colliding."
Returning a virtual character to the physical world therefore turns the traditional animation process on its head, in a sort of reverse rendering, as the image that's on the screen must be adapted to accommodate real-world constraints.
Bächer and his coauthors demonstrated their new method using characters from Spore, an evolution-simulation video game. Spore allows players to create a vast range of creatures with numerous limbs, eyes, and body segments in almost any configuration, using a technique called procedural animation to quickly and automatically animate whatever body plan it receives.
As with most types of computer animation, the characters themselves are just "skins"—meshes of polygons—that are manipulated like marionettes by an invisible skeleton.
"As an animator, you can move the skeletons and create weight relationships with the surface points," says Bächer, "but the skeletons inside are non-physical with zero-dimensional joints; they're not useful to our fabrication process at all. In fact, the skeleton frequently protrudes outside the body entirely."
Bächer tackled the fabrication problem with his Ph.D. adviser, Hanspeter Pfister, Gordon McKay Professor of Computer Science at SEAS. They were joined by Bernd Bickel and Doug James at the Technische Universität Berlin and Cornell University, respectively.
This team of computer graphics experts developed a software tool that achieves two things: it identifies the ideal locations for the action figure's joints, based on the character's virtual articulation behavior, and then it optimizes the size and location of those joints for the physical world. For instance, a spindly arm might be too thin to hold a robust joint, and the joints in a curving spine might collide with each other if they are too close.
The software uses a series of optimization techniques to generate the best possible model, incorporating both hinges and ball-and-socket joints. It also builds some friction into these surfaces so that the printed figure will be able to hold its poses.
The tool also perfects the model's skin texture. Procedurally animated characters tend to have a very roughly defined, low-resolution skin to enable rendering in real time. Details and textures are typically added through a type of virtual optical illusion: manipulating the normals that determine how light reflects off the surface. In order to have these details show up in the 3D print, the software analyzes that map of normals and translates it into a realistic surface texture.
Then the 3D printer sets to work, and out comes a fully assembled, robust, articulated action figure, bringing the virtual world to life.
"With an animation, you always have to view it on a two-dimensional screen, but this allows you to just print it and take an actual look at it in 3D," says Bächer. "I think that’s helpful to the artists and animators, to see how it actually feels in reality and get some feedback. Right now, perhaps they can print a static scene, just a character in one stance, but they can’t see how it really moves. If you print one of these articulated figures, you can experiment with different stances and movements in a natural way, as with an artist’s mannequin."
Bächer's model does not allow deformations beyond the joints, so squishy, stretchable bodies are not yet captured in this process. But that type of printed character might be possible by incorporating other existing techniques.
For instance, in 2010, Pfister, Bächer, and Bickel were part of a group of researchers who replicated an entire flip-flop sandal using a multi-material 3D printer. The printed sandal mimicked the elasticity of the original foam rubber and cloth. With some more development, a later iteration of the "3D-print button" could include this capability.
"Perhaps in the future someone will invent a 3D printer that prints the body and the electronics in one piece," Bächer muses. "Then you could create the complete animated character at the push of a button and have it run around on your desk."
Harvard’s Office of Technology Development has filed a patent application and is working with the Pfister Lab to commercialize the new technology by licensing it to an existing company or by forming a start-up. Their near-term areas of interest include cloud-based services for creating highly customized, user-generated products, such as toys, and enhancing existing animation and 3D printer software with these capabilities.
The research was supported by the National Science Foundation, Pixar, and the John Simon Guggenheim Memorial Foundation.

Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient’s own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow. Bioengineers can already make 2D structures out of many kinds of tissue, but one of the major roadblocks to making the jump to 3D is keeping the cells within large structures from suffocating; organs have complicated 3D blood vessel networks that are still impossible to recreate in the laboratory.
Now, University of Pennsylvania researchers have developed an innovative solution to this perfusion problem: they’ve shown that 3D printed templates of filament networks can be used to rapidly create vasculature and improve the function of engineered living tissues.
The research was conducted by a team led by postdoctoral fellow Jordan S. Miller and Christopher S. Chen, the Skirkanich Professor of Innovation in the Department of Bioengineering at Penn, along with Sangeeta N. Bhatia, Wilson Professor at the Massachusetts Institute of Technology, and postdoctoral fellow Kelly R. Stevens in Bhatia’s laboratory.
Without a vascular system — a highway for delivering nutrients and removing waste products — living cells on the inside of a 3D tissue structure quickly die. Thin tissues grown from a few layers of cells don’t have this problem, as all of the cells have direct access to nutrients and oxygen. Bioengineers have therefore explored 3D printing as a way to prototype tissues containing large volumes of living cells.
The most commonly explored techniques are layer-by-layer fabrication, or bioprinting, where single layers or droplets of cells and gel are created and then assembled together one drop at a time, somewhat like building a stack of LEGOs.
Such “additive manufacturing” methods can make complex shapes out of a variety of materials, but vasculature remains a major challenge when printing with cells. Hollow channels made in this way have structural seams running between the layers, and the pressure of fluid pumping through them can push the seams apart. More important, many potentially useful cell types, like liver cells, cannot readily survive the rigors of direct 3D bioprinting.
To get around this problem, Penn researchers turned the printing process inside out.
Rather than trying to print a large volume of tissue and leave hollow channels for vasculature in a layer-by-layer approach, Chen and colleagues focused on the vasculature first and designed free-standing 3D filament networks in the shape of a vascular system that sat inside a mold. As in lost-wax casting, a technique that has been used to make sculptures for thousands of years, the team’s approach allowed for the mold and vascular template to be removed once the cells were added and formed a solid tissue enveloping the filaments.
“Sometimes the simplest solutions come from going back to basics,” Miller said. “I got the first hint at this solution when I visited a Body Worlds exhibit, where you can see plastic casts of free-standing, whole organ vasculature.”
This rapid casting technique hinged on the researchers developing a material that is rigid enough to exist as a 3D network of cylindrical filaments but which can also easily dissolve in water without toxic effects on cells. They also needed to make the material compatible with a 3D printer so they could make reproducible vascular networks orders of magnitude faster, and at larger scale and higher complexity, than possible in a layer-by-layer bioprinting approach.
After much testing, the team found the perfect mix of material properties in a humble material: sugar. Sugars are mechanically strong and make up the majority of organic biomass on the planet in the form of cellulose, but their building blocks are also typically added and dissolved into nutrient media that help cells grow.
“We tested many different sugar formulations until we were able to optimize all of these characteristics together,” Miller said. “Since there’s no single type of gel that’s going to be optimal for every kind of engineered tissue, we also wanted to develop a sugar formula that would be broadly compatible with any cell type or water-based gel.”
The formula they settled on — a combination of sucrose and glucose along with dextran for structural reinforcement — is printed with a RepRap, an open-source 3D printer with a custom-designed extruder and controlling software. An important step in stabilizing the sugar after printing, templates are coated in a thin layer of a degradable polymer derived from corn. This coating allows the sugar template to be dissolved and to flow out of the gel through the channels they create without inhibiting the solidification of the gel or damaging the growing cells nearby. Once the sugar is removed, the researchers start flowing fluid through the vascular architecture and cells begin to receive nutrients and oxygen similar to the exchange that naturally happens in the body.
The whole process is quick and inexpensive, allowing the researchers to switch with ease between computer simulations and physical models of multiple vascular configurations.
“This new platform technology, from the cell’s perspective, makes tissue formation a gentle and quick journey,” Chen said, “because cells are only exposed to a few minutes of manual pipetting and a single step of being poured into the molds before getting nourished by our vascular network.”
The researchers showed that human blood vessel cells injected throughout the vascular networks spontaneously generated new capillary sprouts to increase the network’s reach, much in the way blood vessels in the body naturally grow. The team then created gels containing primary liver cells to test whether their technique could improve their function.
When the researchers pumped nutrient-rich media through the gel’s template-fashioned vascular system, the entrapped liver cells boosted their production of albumin and urea, natural components of blood and urine, respectively, which are important measures of liver-cell function and health. There was also clear evidence of increased cell survival around the perfused vascular channels.
And theoretical modeling of nutrient transport in these perfused gels showed a striking resemblance to observed cell-survival patterns, opening up the possibility of using live-cell data to refine computer models to better design vascular architectures.
Though these engineered tissues were not equivalent to a fully functioning liver, the researchers used cell densities that approached clinical relevance, suggesting that their printed vascular system could eventually be used to further research in lab-grown organs and organoids.
“The therapeutic window for human-liver therapy is estimated at one to 10 billion functional liver cells,” Bhatia said. “With this work, we’ve brought engineered liver tissues orders of magnitude closer to that goal, but at tens of millions of liver cells per gel we’ve still got a ways to go.
“More work will be needed to learn how to directly connect these types of vascular networks to natural blood vessels while at the same time investigating fundamental interactions between the liver cells and the patterned vasculature. It’s an exciting future ahead.”
With promising indications that their vascular networks will be compatible with all types of cells and gels, the team believes their 3D printing method will be a scalable solution for a wide variety of cell- and tissue-based applications because all organ vasculature follows similar architectural patterns.
“Cell biologists like the idea of 3D printing to make vascularized tissues in principle, but they would need to have an expert in house and highly specialized equipment to even attempt it,” Miller said. “That’s no longer the case; we’ve made these sugar-based vascular templates stable enough to ship to labs around the world.”
Beyond integrating well with the world of tissue engineering, the researchers’ work epitomizes the philosophy that drives much of the open source 3D printing community.
“We launched this project from innovations rooted in RepRap and MakerBot technology and their supporting worldwide communities,” Miller said. “A RepRap 3D printer is a tiny fraction of the cost of commercial 3D printers, and, more important, its open-source nature means you can freely modify it. Many of our additions to the project are already in the wild.”
Several of the custom parts of the RepRap printer the researchers used to make the vascular templates were printed in plastic on another RepRap. Miller will teach a class on building and using these types of printers at a workshop this summer and will continue tinkering with his own designs.
“We want to redesign the printer from scratch and focus it entirely on cell biology, tissue engineering and regenerative medicine applications,” Miller said.
In addition to Miller, Chen, Bhatia and Stevens, the research was conducted by Michael T. Yang, Brendon M. Baker, Duc-Huy T. Nguyen, Daniel M. Cohen, Esteban Toro, Peter A. Galie, Xiang Yu and Ritika Chaturvedi of Penn Bioengineering, along with Alice A. Chen of MIT. Bhatia is also a Howard Hughes Medical Institute investigator.
This research was supported by the National Institutes of Health, the Penn Center for Engineering Cells and Regeneration and the American Heart Association-Jon Holden DeHaan Foundation.

Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, today announced it is cooperating with world-leading consumer products company Keter Plastic Ltd to create an exhibit of 3D-printed art pieces as part of an innovative project to highlight young designers' talents and support at-risk youth.
For the project, 70 art pieces were designed by d-Vision, the design internship program by Keter Plastic and then 3D printed by Objet. The art pieces will be exhibited at the Holon Design Museum, one of the leading museums for design and contemporary culture, on May 30th. The art pieces will be auctioned at a special gala event to benefit ELEM and 'Mifalot Chinuch Chevra', both non-profit organizations that seek to help at-risk youth.
The designers at d-Vision developed their concepts in 3D CAD software and then 3D printed them on Objet's 3D printers. Created in rigid opaque materials, Objet's high resolution 3D printers were able to precisely create real-life 3D renditions of the designs - creating true works of art.
"This project brings together many elements that are central to d-Vision: outstanding design and art, advanced technology, and commitment to our community," said Professor Ezri Tarazi, head of the d-Vision program. "We were delighted to see how our young designers' artistic ideas turned into spectacular reality through the high-quality 3D printing capabilities of Objet. We are looking forward to seeing how our combined efforts will eventually help make a difference in young people's lives, through the money raised by auctioning the art pieces for ELEM and Mifalot Chinuch."
Commenting on the project, David Reis, CEO for Objet said: "We are delighted to be participating in this very prestigious design project and proud to be contributing to the commendable work of ELEM and Mifalot Chinuch in working to ensure a better future for our youth. By pairing d-Vision's innovative and artistic designs with Objet's advanced 3D printing technology, we have created a powerful platform to expand the boundaries of art and design while contributing to the betterment of the community."
d-Vision was established in 2005 and is a unique internship program and the first of its kind in Israel, for product development and design. The project was envisioned by Sami Sagol, owner and chairman of Keter Group, with the aim of integrating between Academy in industrial design, product engineering and technology to the needs and future development of industry. Its focal point is to fill the missing link between Academia and Industry, with the aim of cultivating the next generation of excellent young designers and product developers that combine creativity with technology application.
Every year 15 outstanding design graduates are selected from the Design Academies in Israel: Bezalel, Shenkar, Holon Institute of Technology and Hadassa. During the two year program they get professional experience in product development for the international market.
The interns also develop innovative concepts, new and cutting-edge technologies are introduced to renowned designers and visit professional international fairs.
d-Vision exhibited in international fairs such as Salone Satellite in Milano, in the Dutch Design Week and others.
Prof. Ezri Tarazi and Ms. Tzipi Kunda head the program.
The program includes sponsored Masters Degree in Designing and offers job positions in Keter to the graduates of the program.
The program also promotes contribution to the community and each team engages in a special community project. This year the program managers decided that the contribution will focus on two organizations: "Elem, Youth in Distress" and "Education and Social Projects".
World-renowned dental implant specialist, Andrew Dawood, bought an EOS plastic laser-sintering machine in 2009 for his Wimpole Street company, Cavendish Imaging, so that data from CT (computerised tomography) scans could be used to make anatomical replicas of a patient's jaw and teeth. The purpose was to be able to plan and carry out complex dental procedures such as zygomatic implant placement more efficiently and accurately.
After the needs of his own dental practice and those of others locally had been met, the service was extended to assist other medical professionals. A recent, high profile job was the production of surgical planning models from MRI scans taken of shared blood vessels within the skulls of Sudanese baby twin girls, Ritag and Rital Gaboura, who were conjoined at the head. Last September (2011), doctors at Great Ormond Street Hospital separated the girls and they survived against incredible odds.
There was still spare capacity on the EOS FORMIGA P100 laser-sintering machine, which automatically builds finely detailed models from successive 100-micron layers of fine, white nylon powder in a process sometimes referred to as 3D printing. So Mr Dawood decided to start another firm, Digits2Widgets, to offer a similar service to designers, initially mainly in the conceptual arts and architecture.
The enterprise has seen the machine produce a wide variety of prototypes and finished products. Work includes helping with customisation of dolls' faces, and 3D scanning, digital modification and small production runs of items such as innovative jewellery and spectacle frames, either directly in plastic or in metal via lost wax models.
Another project involved the limited production of plastic 'clones' – modified pine cones containing a light – that appeared in the list of best Christmas tree decorations 2011 published by The Guardian newspaper.
The area of London around Wimpole Street is at the epicentre of world renowned schools of Architecture, such as the Architectural Association, Westminster University, The Royal College of Art and the UCL Bartlett School of Architecture. The latter also operates a FORMIGA P100 as well as a larger plastic laser-sintering machine from EOS. Mr Dawood therefore took the logical decision to employ a qualified architect to help expand the design side of his business.
That person is Jonathan Rowley, BArch, DipArch, ARB, who joined Digits2Widgets in August 2011 and has since been responsible for producing several scale models of buildings in multiple sections for architectural practices and students.
He commented, "The big advantage of laser-sintering as a 3D printing method is that the parts produced are robust and fully functional, unlike with some other additive manufacturing methods.
"Once the 3D model has been sliced horizontally and the data downloaded to the FORMIGA control, the build process continues automatically around the clock, layer by layer, until the process is complete. You then simply lift out the hopper, allow it to cool and extract the components, dusting off the powder residue.
"Different parts can be fitted together in our CAD (computer aided design) system and produced simultaneously within the machine's 200 mm x 250 mm x 330 mm build volume in one cycle, so productivity is high, allowing us to keep down costs.
"We still have spare capacity on the machine to offer to firms in the London area, nationwide or even internationally, and may well invest in another, larger EOS 3D printer as business increases."
When it comes to the manufacture of designer furniture in small batches, more and more providers are relying on 3D print technology, which can be used to produce spectacular designs at economic production costs, as evidenced by the Batoidea chair.
Batoidea, or stingray, is the name of a designer chair created by Belgian star designer Peter Donders. One look at this refined piece of furniture reveals the idea behind the name, as the design really does conjure up the image of an elegantly gliding stingray, visualising lightness and airiness, and impressing with its elegance. The production of this chair, which breaks with convention and is made of aluminium casting, would have been virtually impossible in terms of economic aspects without the use of 3D print technology.
Peter Donders was able to implement his unconventional ideas inspired by nature on a technical level using a computer and the well-known Rhino3D modelling program. The great advantage of this progressive work method: The CAD data set required for 3D printing was automatically available upon completion of the work on the computer.
The production of the generously sized chair with its complex stingray design required a total of five sand mould parts, which were manufactured at voxeljet's service centre in Augsburg. The largest mould part measured 1,105 x 713 x 382 millimetres – a size easily handled by voxeljet's high-performance printers. The largest voxeljet 3D print systems can accommodate shapes with a maximum volume of eight cubic metres.
The chair production process places great demands on 3D printing and the cast, as the design consists of a very thin-walled aluminium cast structure. The casting process is followed by grinding and polishing work, before a high-quality varnish is applied to the Batoidea chair.

To commemorate the 100th anniversary of Fenway Park, Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, is unveiling a large-scale, 3D-printed replica of the celebrated ballpark. Designed in 3D software, using blueprints and up-to-date images, the 3' x 5' replica captures even the finest details of Fenway, from the Green Monster and Pesky Pole to the exact number of lights and famed, red Ted Williams seat in right field.
The 3D replica, which was printed on an Objet Connex500 multi-material 3D printer at the company's North American headquarters in Billerica, is about 1/200th scale, includes 40 separate printed sections and weighs about 105 pounds. The model will be on display this week and in the coming months through Boston.
On April 19, the Fenway replica will be on display at Game On!, where it will join other Fenway memorabilia on display during the Fenway 100 Magazine Launch Event hosted by the Boston Globe. There, columnist Dan Shaughnessy will moderate a panel discussion with former players, historians and fans, including Bill Lee, Ken Casey, John Powers and Dick Johnson.
On April 20, the 3D-printed replica will be on display at the Museum of Science for an hour-long demonstration of 3D printing. Objet then will donate the 3D print to the Boston Sports Museum.
"As longtime Red Sox fans, and frequent visitors to Fenway, we wanted to celebrate this historic event by sharing something that all fans could appreciate,'' said Bruce Bradshaw, Director of U.S. Marketing for Objet. "Objet's printers are used by architecture firms around the world to create incredibly detailed models in mere hours rather than weeks; so it seemed a natural fit for us to use this technology to recreate Fenway and deliver it to people throughout Boston."

A revolutionary technique being developed by scientists at Loughborough University could free architects from the restraints of current construction methods.
Architects are creating stunning buildings with intricate geometric forms, but many never progress beyond the designer’s screen because their complexity makes them too costly to construct.
A team, led by Dr Richard Buswell and Professor Simon Austin from the University’s School of Civil and Building Engineering, has made dramatic progress with additive manufacturing technologies, where models created on-screen can be formed into three-dimensional components at full scale.
Conventionally, concrete is poured into temporary formwork – an efficient method of moulding if the shapes are straight, simple and the variations minimised. Introduce curves and complexity, and the expense rapidly increases.
In the Freeform Construction project, a special type of concrete is deposited very precisely under computer control, layer by layer, from a 3D computer-aided-design (CAD) model. Using this technology, very complex sections of buildings can be created without the high cost penalties associated with traditional methods.
Speaking about the project Dr Richard Buswell said: “Using Freeform every section of a building could be unique if necessary – produced by calling up a new design on-screen and setting the process to work. Components could be created with ready-made internal voids and ducts for services, and with shapes that made the most of their insulating properties. Because each piece would be tailor-made, there would be virtually no waste. The possibilities are endless; it is a very exciting project.”
This pioneering work has been made possible by funding from the Engineering and Physical Sciences Research Council (EPSRC) with significant input from industry.
The research team has now obtained technology-transfer funding from the EPSRC to commercialise the process, collaborating with Foster + Partners, Buro Happold and Hyundai Engineering & Construction. Their expertise and advice is essential to the team’s understanding of the needs of industry, the potential of their ideas and the creation of an innovation path.
The Freeform work has generated interest worldwide and already led to exhibitions in Barcelona, New York and London.
Colin McKinnon, Innovation Director at Buro Happold, said: “Through our involvement in the project we will help the research team assess the design, manufacturing and commercial potential of this innovative technology.”
Xavier De Kestelier, Associate Partner, at architects Foster + Partners added: “This project gives us tremendous opportunities to see what construction technology will be like in the next five or 10 years.’’

Furniture fittings specialist Armac Martin has announced a rise in sales orders since installing an Objet24 Desktop 3D Printer at its facility in Birmingham, UK. "Since the introduction of 3D printing we are turning more of our customers' ideas into new products and as a consequence we are winning more orders for our factory," confirms Paul McGrail, Armac Martin Managing Director.
Armac Martin designs and manufactures handles, knobs, bolts, catches, castors, door knockers, hinges and other furniture fittings, many of which are bespoke designs specified by customers. The Objet24 Desktop 3D Printer, used to test new designs and produce product samples for customer approval, is enabling Armac Martin to save costs and service customers faster according to Mr. McGrail: "Now we have the Objet24 3D Printer working in conjunction with our 3D CAD capability, our Technical Sales Managers are able to get one-off samples to customers without interrupting production on our CNC machines. This means samples are with customers up to four weeks faster than before, sometimes in just a couple of days from the initial discussion. We're also making savings in tooling which would normally be required to produce the samples in metal."
Ease and quality of finishing are also key aspects of producing the samples. "We compared a couple of different rapid prototyping technologies and found that Objet provided the fine detail and quality of finishing we require for our work. Our products are high-quality decorative items so it's very important that samples are beautifully finished," says Mr. McGrail.
Armac Martin purchased the Objet24 Desktop 3D Printer through Objet UK distributor HK Rapidprototyping. Nigel Bunt, Sales Director at HK Rapidprototyping, adds: "It was clear from the start that prototype realism was vital for Armac Martin. Objet 3D printed parts are very easy to finish to a superb standard, which Armac Martin verified in tests with competitive models."
To achieve realistic prototypes, Armac Martin spray paints the majority of parts produced on the Objet24 Desktop 3D Printer. Mr McGrail elaborates, "The majority of the time we paint the 3D printed models in a silver or gold to emulate metal fittings like door handles or knobs and we've had some parts nickel-plated. Parts are also often drilled so that they can be fitted in the same way as the final product. Our customers need to be able to visualise the final effect; the realism of samples produced with Objet 3D printing makes this possible."
Mr. McGrail concludes, "From the first approach to HK Rapidprototyping, through subsequent meetings and producing our first parts, the service has been nothing short of excellent. This, combined with the exceptional quality of samples we're producing, and ease-of-use of the Objet desktop 3D printer has made this purchase a great success for us."

A builder's capacity for three-dimensional imagination is quickly overwhelmed when it comes to the assessment of drafts for larger structures. Therefore the ability of architects to present the quality of their work in the most realistic and detailed light as possible is becoming ever more important. Architectural models from 3D printers are the top choice in this regard, as shown by a project for a social centre in Ghana.
Munich architect Wieland Schmidt is already a well-known figure at voxeljet's service centre in Augsburg, as he was one of the first to identify the opportunities offered by 3D print technology for the production of small-batch models or products. "It is fascinating to see how concrete models or products can be created from CAD data in such a rapid and uncomplicated manner. The options provided by 3D printing have also proven themselves with regard to the planning of a trend-setting social centre in Ghana", says Schmidt.
This story starts with a storm in Ghana, more specifically in Sunyani. That is where the Catholic diocese operates an educational institution that comprises more than 200 kindergartens and almost 400 schools ranging from elementary school to university. The church also runs a large number of other social projects designed to help the poor. The diocese also operated a large community hall. However, the hall was damaged by a heavy tropical storm, which tore off the entire roof, hurled it through the air and destroyed it. It was a miracle that no one was hurt, but the hall could not be saved and had to be demolished.
The decision was made to build a new social centre to continue the diocese's successful work. The new complex is designed for a multi-use environment and supposed to act as a meeting place in addition to functioning as the administration for the diocese.
This trend-setting project was planned and designed by Wieland Schmidt: "We want to achieve a lot with the new building complex. We want to build it in an environmentally-friendly manner, using materials from the surrounding area, while at the same time it is designed to be as self-sufficient as possible on an energetic level. Given the tropical heat, it is important to ensure that the building does not heat up, while the energy needs of the building will be covered by solar elements."
Impressive 3D model from Augsburg
Of course everyone in Ghana was curious as to what the new building complex would look like in detail. Therefore Wieland Schmidt decided to digitalise the building data and print out the entire social centre. The voxeljet service centre used the proven method of printing on a high-performance VX800 printer. This equipment is predestined for generating models that require absolute attention to detail and a precise representation. The VX800 generated the Christ the King Social Center in plastic directly from CAD data on the basis of the so-called layer building method (dimensions 840 x 840 x 225 millimetres). Using thousands of micro-metre fine layers, the VX800 built the entire building in approximately one day.
Following the unpacking period – a process during which excess material is removed from the model – the Christ the King Social Center became reality, at least in terms of a model. "The architectural model of the social centre was printed with a richness of detail and precision that is the hallmark of voxeljet quality. Also, the excellent mechanical stability of the 3D prints ensured that the model withstood the long journey from Augsburg to Ghana without any damages," says Wieland Schmidt.
Once the model arrived in Sunyani, Bishop Matthew Kwasi Gyamfi and his staff took a closer look at the model from Augsburg: "The compelling 3D model allowed us to gain a realistic picture of the building – we are very excited. The concept put forward by architect Schmidt is very impressive and perfectly tailored to our needs. We hope to construct the building as quickly as possible," says Bishop Gyamfi.
In fact, 3D printing is perfectly suited for this form of presentation. The plastic models make it easy to assess dimensions and proportions, therefore more and more architects rely on the advantages of 3D printing for important presentations. At the same time, there is an increasing demand for purely white models, which has prompted voxeljet to offer a new binder type, effective immediately. The new material is called Polypor Type C and differs from the standard binders in that the finished plastic models feature a very white colour and are thus able to meet demanding requirements with respect to the model's look and feel. This means that 3D printing is becoming even more attractive, particularly for architectural models and design studies.

Objet GmbH, a subsidiary of Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, exhibits the latest in 3D printing technology and its real-world applications at Hannover Messe 2012.
“Objet leads the way in high-quality, professional 3D printing,” states Eric Bredin, European Marketing Director for Objet. “With a portfolio of nearly 70 materials of varying physical and mechanical properties, Objet has the most diverse range of 3D printing materials on the market; enabling our customers to produce the most exceptionally realistic prototypes.”
Visitors to Hannover Messe can see stunning examples of true-to-life prototypes on the Objet stand, including a fully-assembled car dashboard complete with display screens. 1.4 meters wide and assembled from over 20 individually printed parts, the dashboard was produced for StreetScooter, a project involving a consortium of over 80 companies, united with an aim to develop an affordable electric car with an emphasis on sustainability. Major parts of the dashboard were printed in the Objet ABS-like Digital Material, chosen for its exceptional dimensional stability and toughness. Additional Objet materials were used to simulate fine-details. The parts were then glued, polished and painted to precisely simulate the true look, feel and function of the dashboard.
Further prototype models on the Objet stand illustrate real-life applications from a diverse range of industries including automotive and defence parts, kitchen utensils, special effects for film and television, medical devices, dental veneers, footwear and more.
The entry-level Objet Desktop printer runs live on the Objet stand, alongside the unique and widely acclaimed Objet Connex500 multi-material 3D printer. Demonstrating the advantages of multi-material 3D printing, the Objet Connex500 can print models with varying properties from rigid to rubber, opaque to transparent, to engineering plastics simulation.
Stratasys and Optomec Inc. today announced that the companies have successfully completed a joint development project to merge 3D printing and printed electronics to create the world’s first fully printed hybrid structure.
The first project, the development of a “smart wing” for an unmanned aerial vehicle (UAV) model with functional electronics is a revolutionary event that has the potential to change product development in industries including medical device, consumer electronics, automotive and aerospace.
“Bringing together 3D printing and printed electronic circuitry will be a game changer for design and manufacturing,” says Jeff DeGrange, VP of direct digital manufacturing at Stratasys. “It has the potential to completely streamline production by requiring fewer materials and steps to bring a product to market.”
An Optomec Aerosol Jet system was used to print a conformal sensor, antenna and circuitry directly onto the wing of a UAV model. The wing was 3D printed with the Stratasys Fused Deposition Modeling (FDM) process. The electrical and sensor designs were provided by Aurora Flight Sciences, a supplier of UAVs. “
We envision many potential applications of the Stratasys-Optomec approach for hybrid direct digital manufacturing,” said David Kordonowy, who leads Aurora Flight Sciences’ Aerostructures Research Group. “The ability to fabricate functional electronics into complex-shaped structures using additive manufacturing can allow UAVs to be built more quickly, with more customization, potentially closer to the field where they’re needed. All these benefits can lead to efficient, cost-effective fielded vehicles.”
The combination of FDM 3D printing and printed electronics technologies can provide benefits over traditional prototyping, manufacturing and field repair processes. Performance and functionality of products can be improved in two ways: 3D printers enable lighter weight mechanical structures; and conformal electronics printed directly onto the structure frees up space for additional payload. In turn, the process has a positive impact on the environment by using fewer materials.
“Manufacturers can implement this hybrid technology in a multitude of applications, not just in aerospace,” says Optomec’s Ken Vartanian. “This technology can benefit numerous industries by allowing thinner, lighter, fully functional structures that cost less to manufacture.”
For their latest feature film, The Pirates! In an Adventure with Scientists!, Aardman chose the envisionTEC Perfactory® Standard machine as their first choice for 3D Printing of the heads and mouths. This technology was chosen for a number of reasons. With the possibility of over 20,000 mouth replacements, planned accuracy was an essential feature of the printing method. The mouths also needed to be interchangeable, all exactly fitting the characters’ heads. With such a large number of mouths required during filming, the system needed to run 24/7 and be capable of producing hundreds of pieces every day. envisionTEC UK supplied Aardman with four Perfactory® Standard machines, all set to produce the mouths within 30 micron accuracy and running the E-shell range of materials. Aardman started work in 2009 manufacturing heads with interchangeable mouths for all the main characters and they also used the technology for making prototypes for maquettes. The film was produced on time and within budget with the help of this latest technology.
In The Pirates! In an Adventure with Scientists 3D, Hugh Grant stars in his first animated role as the luxuriantly bearded Pirate Captain – a boundlessly enthusiastic, if somewhat less-than-successful, terror of the High Seas. With a rag-tag crew at his side (Martin Freeman, Brendan Gleeson, Russell Tovey, and Ashley Jensen), and seemingly blind to the impossible odds stacked against him, the Captain has one dream: to beat his bitter rivals Black Bellamy (Jeremy Piven) and Cutlass Liz (Salma Hayek) to the much coveted Pirate Of The Year Award. It’s a quest that takes our heroes from the shores of exotic Blood Island to the foggy streets of Victorian London. Along the way they battle a diabolical queen (Imelda Staunton) and team up with a haplessly smitten young scientist (David Tennant), but never lose sight of what a pirate loves best: adventure!
In response to businesses and manufacturers looking to accelerate product development and speed new products to market, the Society of Manufacturing Engineers (SME) RAPID 2012 Exposition will feature the latest innovations in 3D imaging, 3D printing and additive manufacturing technologies. The annual event takes place May 22-25 in Atlanta and will attract exhibitors and attendees from around the world, including Ireland-based Mcor Technologies who recently 3D printed a Shamrock to create awareness and celebrate St. Patrick's Day.
New to the RAPID 2012 Exposition is Ireland-based Mcor Technologies Ltd. The company will debut its Matrix 300, the world's only 3D printer that uses reams of recycled 8 ½ x 11" paper and water-based adhesive to make 3D objects. 3D printing, often referred to as additive manufacturing, is a process used to create rapid prototypes and functional end-use parts. Analysts believe 3D printer manufacturers, such as Mcor, play an important role in creating awareness of an industry that's expected to reach $3.1 billion by 2016 and $5.2 billion by 2020.
"Every year SME works diligently to unveil something ground-breaking and new to conference attendees, and this year we've assembled a diverse, international representation of the world's most innovative technologies," said SME business development manager, Gary Mikola. "We're thrilled that Mcor Technologies has chosen RAPID 2012 as the first venue to introduce their 3D printer to the United States."
For nearly two decades, additive manufacturing has been used by several industries including aerospace and defense, medical devices, motor vehicles and consumer products. The annual RAPID Exposition has been instrumental in promoting the applications and uses of additive technologies in early stage product design and in production. The launch of more affordable 3D printers is helping to create widespread adoption.
"We are very excited to present the Matrix 300, at RAPID 2012," said Mcor Technologies co-founder and CEO Dr. Conor MacCormack. "The Matrix makes low-cost, green, good quality 3D printing accessible to everyone, and we believe that we have the prototyping technology that will soon be as ubiquitous as printing in 2D." The company intends to reach a broader market by making the equipment as easy-to-use as a 2D printer and affordable for cost-conscious companies and universities. Editors: See photo of 3D printed shamrock on page two of this release.
The RAPID show floor will offer access to wide-ranging applications of additive manufacturing and 3D imaging technologies in several traditional industries while highlighting new applications in architecture, arts and entertainment. A reoccurring theme throughout the event will demonstrate how companies can use rapid technologies to reduce design and development time, cut production timeframes and lower costs. In 2011, the RAPID event attracted 200 international attendees from 27 different countries. Access to the expo is included with the cost of the conference; however, it's open to walk-ins for $49 each day.
Daniel Hilldrup, Artist in Residence at the London Metropolitan University, has unveiled new Objet 3D printed artwork in a series titled 'Fragments in Time'. Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, printed the two striking pieces, which Hilldrup describes as contemporary fossils.
Flux and Aquiform in Rest were produced on an Objet Connex 3D Printer, with the unique capability of printing multiple materials and properties in a single print run, allowing Hilldrup to simulate movement and fluidity in his first piece ‘Flux’.
“Necessity being the mother of invention, I’m often influenced and motivated by technology, so I keep an ear to the ground for new technologies,” states Hilldrup. “I first heard about Objet multi-material 3D printing and thought ‘wow – this is a game changer’. It was the Objet Connex technology that inspired these pieces. For example, without the multi-material aspect it would not have been possible to print the Flux candelabra, and if I was to produce it via traditional methods – casting it in a block of glass – it would be a very difficult thing to achieve, and there would be a loss of control over the final piece.”
Flux: Described by Hilldrup as “a statement on the transference of energy and its transition and total transformation from one physical state and form into another”, Flux depicts black candle wax melting into the liquid base of a candelabra, captured, like a fossil, at a specific moment in time.
The ‘fluid wax’ was printed in Objet black rubber-like material (Objet TangoBlackPlus), which appears to be melting into liquid, but is in fact encased in a solid base of Objet clear transparent, rigid material (Objet VeroClear). The removable candle holders were printed separately in Objet rigid opaque black material (Objet VeroBlack). Hilldrup finished the pieces by hand to a very high standard, polishing the surfaces to achieve a superior level of clarity.
Aquiform in Rest: A free standing sink basin possessing a sculptural form. As its name suggests, it captures the motion of agitated water within a constrained volume. Printed in Objet clear transparent material, it has been finished with a two-pack polyurethane paint.
Hilldrup’s work aims to create design that is beautiful, fit for purpose, and that provides benefits, or otherwise enriches the life of the user, he comments, “My interest is the creation of functional sculpture and innovative object forms where there is an emphasis on the aesthetic and narrative of a piece, but not at the expense of usability. I wish to explore the boundaries between art and design by embracing digital tools, manufacturing technologies and through associated process pipelines and craft.
“In this sense I’m really pleased with both pieces. The Objet multi-material Connex capability allows you to approach the work from a different angle, potentially working on concepts you couldn’t otherwise achieve. I’m very happy with how the pieces have translated; sometimes you do something in the virtual domain and then it doesn’t quite come up to scratch when you do the physical piece. In this case I’m really pleased with the pieces across the board, the way the materials and finish have translated the concept. I’d certainly call them a success.”
Daniel Hilldrup Researcher, Lecturer and Artist in Residence at the London Metropolitan University, practices digital-craft and embraces digital fabrication technologies to realize pieces that span the art and design domains, to create functional sculpture and objects of 'beautility'. Hilldrup’s aim is to create innovative object forms where there is an emphasis on the aesthetics and narrative of a piece, but not at the expense of usability.

RedEye On Demand, a digital manufacturing service and business unit of Stratasys, Inc. (NASDAQ: SSYS), has collaborated on a project with the Smithsonian to create one of the largest 3D-printed, museum-quality historical replicas in the world.
The life-size statue of Thomas Jefferson is a central piece of the Smithsonian’s National Museum of African American History and Culture (NMAAHC) exhibition, “Slavery at Jefferson’s Monticello: Paradox of Liberty,” which runs through October 14, 2012.
“The details RedEye On Demand incorporated into the Jefferson statue and the quality of the model exceeded our expectations,” says Dorey Butter, Project Manager, NMAAHC. “3D printing supports the Smithsonian’s mission to increase and diffuse knowledge. Touchable models and scientific replicas can help further our efforts to educate our visitors, and the technology and services at RedEye On Demand have opened our eyes to different possibilities.”
To develop the statue, the Smithsonian's Digitization Program Office took 3D laser scans of an already existing statue created by StudioEIS and residing at Thomas Jefferson’s Monticello home near Charlottesville, Va. That data was sent to RedEye On Demand as a digital model, and the statue was produced in four parts using Stratasys’ patented Fused Deposition Modeling (FDM) technology.
The statue was created entirely from production-grade thermoplastics for strength and durability. RedEye On Demand employed a sparse-fill technique for the interior of the statue, much like a honeycomb, to reduce the figure’s weight and lower cost while still preserving quality and retaining strength.
Total build time was nearly 400 hours, or about two and a half weeks, compared to a several month production time for a traditional bronze statue of this size. Once assembled, the figure was “bronzed” through a creative application of primer, paint and wax to give the statue a realistic patina.
“The statue points to the range of possibilities with 3D printing and production,” says Richard Garrity, VP of RedEye on Demand. “We are expanding the reach of our services beyond traditional design firms and product development, and our work with the Smithsonian demonstrates our ability to offer customized parts and products for unique, one-off applications in an affordable way. As demand for this kind of rapid customization continues to increase, so do the capabilities and quality of our work, and this project is just one example of what we can do,” he adds. Once the Smithsonian exhibition ends, the statue may be used for educational purposes at Monticello.
A case study of the project is available at: www.redeyeondemand.com/CS_TJefferson.aspx
Researchers at Drexel University are bringing the latest technological advancements in 3-D printing to the study of ancient life. Using scale models of real fossils, for the first time, they will be able to test hypotheses about how dinosaurs and other prehistoric animals moved and lived in their environments.
“Technology in paleontology hasn't changed in about 150 years,” said Drexel paleontologist Dr. Kenneth Lacovara, an associate professor in the College of Arts and Sciences. “We use shovels and pickaxes and burlap and plaster. It hasn't changed -- until right now.”
3-D Printing Technology in Paleontology
Lacovara has begun creating 3-D scans of giant dinosaur bones and other fossils in his lab. The 3-D scan puts a virtual image in a digital workspace that researchers can manipulate and analyze. To bring these scans to life, Lacovara is also teaming up with mechanical engineer Dr. James Tangorra, an assistant professor in Drexel’s College of Engineering, to use 3-D printing technology to create and test scale models of fossil bones.
A 3-D printer is a technology for rapid prototyping and manufacturing objects based on a digital design. Common models work by repeatedly extruding extremely thin layers of a resin or other material, building up strata to create a physical object.
“It’s kind of like Star Trek technology, where you can press a button and the object pops out,” Lacovara said. A six-inch model of a dinosaur bone can be printed in a few hours using current technology.
Using 3-D printing can aid paleontology in several ways:
This biologically-derived modeling to test possible movements of extinct species is the major focus of Lacovara and Tangorra’s collaboration.
Robotic Models to Test Mechanics of Dinosaur Movement
“We don’t know a lot about the way dinosaurs move,” Lacovara said. “How did they stand? How did they ambulate? Did they run or trot? How did they reproduce? It’s all a bit mysterious,” especially when it comes to the largest dinosaurs. Paleontologists’ current methods of understanding such mechanics rely heavily on guesswork and common sense about what types of movements seem possible. With new technology, researchers can begin testing their predictions for the first time.
Lacovara has been part of scientific teams unearthing some of the largest known giant sauropod dinosaur specimens, including the new species Paralititan stromeri found in Egypt in 2000, which is the second-most-massive known dinosaur species and a new giant from Patagonia. Such giant sauropod dinosaurs could reach weights of 60 to 80 tons, which is 12 to 14 times heavier than a large modern elephant.
When working with enormous dinosaur fossils, Lacovara said, it’s simply physically impossible to manipulate the bones to test theories about mechanics and movement. That’s why scaled-down replicas that preserve the exact shape and proportion of the bones can help. Researchers can also digitally reshape the models to correct for changes that may have occurred over millions of years of fossilization and compression.
Lacovara and Tangorra will work together to create robotic models of giant sauropod dinosaurs, attaching artificial muscles and tendons to perform comprehensive tests of how the animal’s body could have handled physical stresses of the environment.
This work is similar to Tangorra’s ongoing work modeling and manufacturing robotic fish. “We extract features from biological species and create software-based or robotic testing systems. It’s easier to test a biorobotic system than a biological system,” Tangorra said. This work relies on studies of the fish’s movements, biomechanics and fluid mechanics to ensure that the robot reflects the biological system. Tangorra noted that because the dinosaur species they are modeling are extinct, any robotic reconstructions will be more speculative.
Lacovara predicts that they will have a working robotic dinosaur limb constructed by the end of 2012. A complete robotic dinosaur replica will take one to two years to create.
“A Virtual Zoo of Cretaceous New Jersey”
In addition to constructing models of giant dinosaurs, the researchers will make 3-D models of some fossils found closer to home. A fossil dig site in Gloucester County, N.J., has yielded a large number of marine animal fossils from the Cretaceous period, 65 million years ago. Lacovara and his students and collaborators from other institutions continue to excavate the site. Now they will begin producing 3-D models of the turtles, crocodilians, fish and other animals found at that site, for what Lacovara called “a virtual zoo of Cretaceous New Jersey.” A sample of their first reconstruction, of an ancient New Jersey crocodile, can be seen here: www.drexel.edu/now/features/archive/2011/November/Evan-Boucher-Dream-Job
See A Giant Dinosaur Bone and its 3-D Model in Philadelphia
A cast of the giant, 5.5-foot-long humerus bone of the Paralititan dinosaur is on display alongside a 1/10 scale 3-D printed model at the Franklin Institute as part of the Giant Mysterious Dinosaurs exhibit. The Franklin and the Academy of Natural Sciences of Drexel University are offering a “Giant Dinosaur Deal” combination ticket, available at the box offices of both museums through March 18, 2012.

When a beloved museum in upstate New York needed a new master plan for its sprawling campus, it turned to a potent resource to spark the brainstorm: students at the Rensselaer Polytechnic Institute (RPI) School of Architecture.
They delivered in a big way, producing "Building Futures: Re-Envisioning The Hyde at Rensselaer," an exhibit at the Hyde Collection in Glens Falls, N.Y. Running February 11, 2012 - April 16, 2012, the exhibit comprises 14 visionary proposals for conceptually unifying the seven-acre campus, its three historic homes, a 1989-vintage addition and future expansion. 3D Systems Corporation proudly sponsored RPI in 3D printing the architectural models for this cutting edge exhibit.
"Our students came up with some wonderfully bold proposals," observed Andrew Saunders, assistant professor of architecture at RPI, who led the project. "They expressed some inventive ways of reconsidering the problem and the potential of the site. Polemically charged, the proposals take the master planning discourse to new, unexpected places, putting different levels of emphasis on the physical, regional, environmental, institutional, historical, economic and cultural contexts. If we help the museum's leadership explore new areas as they ponder its future, we have succeeded."
3D printing is a new and affordable way of creating architectural models faster and more accurately than traditional, labor-intensive handcrafting. RPI's ZPrinter(R) from 3D Systems creates physical models from 3D computer-aided design data much as a document printer creates a business letter from a word-processing file.
RPI has used 3D Systems 3D printers since 1998, and its current full-spectrum color ZPrinter operates "non-stop" during a typical semester, says Saunders. He sees its speed, quality and affordability as a major advantage for students needing to create models, especially 11th-hour end-of-semester projects. As at many campuses, RPI students in other disciplines, such as mechanical engineering and fine art, have caught wind of the ZPrinter's capabilities and are using it in their projects.
"The Hyde exhibit, in addition to revealing possibilities for a new museum campus, is exposing a large community of museum patrons to what the Rensselaer School of Architecture can do with the newest technologies," said Saunders. "A lot of people are fascinated with what we've created and how we've created it. It's just one illustration of the progressive mindset of the school, museum, faculty and students."

This article covers my concept and design process for creating a sound-hole guard for my acoustic guitar. The idea was to protect my guitar from damage and wear after long and repeated use of a pick while strumming.
Some time ago I decided to replace the pick guard on my vintage Guild acoustic guitar. I play it all the time, and it holds a lot of sentimental value for me. It was my very first guitar. I purchased it new back in 1982 in Northern California. After nearly 30 years of use, some minor maintenance and repairs were in order, including replacing the original pick guard. I removed the old pick guard, cut out a new pattern matching the old guard (using new acrylic plastic) and applied the new one on to my guitar. That’s when I decided something needed to be done in order to prevent any further damage to the lower portion of the sound-hole. I noticed over many years using a pick while that this area had eroded away considerably. Bare wood from the soundboard was now exposed and continuing to grow in length downward from the sound-hole edges. Depending on the guitar manufacturer, there is usually a gap between the edge of the sound-hole and the beginning of the pick guard, which runs concentric to the sound hole. Regardless, the edge of the sound-hole and soundboard on acoustic guitars are exposed and unprotected from damage, something where even moderate use can have long-term affects.
My initial concept was to develop a flat pattern that could be laid onto the soundboard with an overlapping piece that bent around to the back of the sound-hole. The development piece would have to have a pressure sensitive adhesive in order to adhere in place. I used a .020 thick piece of Mylar for the original pattern, but soon afterward came up with another concept that would act as a more permanent and stronger solution. That fix turned out amazingly well and is still on my guitar.
I designed a flat pattern out of .125 thick piece of polycarbonate, heat formed it around a fixture that duplicated the sound-hole/soundboard dimensions. This design acts as a clip that fits over the lower half of the sound-hole. I attached the prototype piece onto my guitar with some silicon rubber adhesive in order for it to stay in place. Although this prototype proved to prevent any further damage to the area, I felt I needed to refine the design by reducing the wall thickness (the prototype appeared to be too bulky) and to simplify the fit by eliminating the use of an adhesive.
Then I picked up a seat of SolidWorks so I could properly build and design 3D solid models. This was something I had been putting off and had wanted to do for quite a while. My guitar project prompted me to take some action. After familiarizing myself with the software, I decided to tackle the sound-hole guard project. My first design incorporated negative draft on the two walls to act as a clip to squeeze onto the soundboard. I also designed three concentric ridge features on the inner wall to act as teeth to bite onto the soundboard, preventing movement and eliminating the need for the adhesive.
After converting to my first .stl file, I was ready to shop for a prototype service that would build the part. I was a little disappointed in discovering the pricing structures I was looking at, as my part did not seem very intricate or big. Searching further, I found ZoomRP who’s pricing seemed reasonable. Plus they offered very fast turn-around times, and their on-line quoting system was convenient and almost immediate, within seconds after submitting the .stl file. I decided to go with the Poly Jet HD Blue process, which advertised the highest resolution, highest accuracy, and was specific to smaller prototypes.
When I received my first part, I was completely impressed by the accuracy and quality of the surface finish and to the details of the very small teeth on the inner wall. My part would allow me to test for fit and function on my guitar. The only problem I experienced was an interference issue, which I overlooked in the design process. The inside edge of the outer wall of the part was catching on the edge of the pick guard. This prevented it to seat properly. The dimension of the outer wall of the part was too close to the location of the edge of the pick guard. So I went back to solving this issue on SolidWorks.
I also felt it necessary to play around with wall thickness and draft. Thickness of .100 still seemed too thick and the fit also seemed too tight on the guitar. I did extend the front wall to fit over the pick guard and added a small radius extending the entire inner edge.
A couple of designs later I was finally able to fine tune all design concerns including the right amount of draft, wall thickness, overall length, and front wall length, (final part: pic-4, front view and back view). I now feel very comfortable that this piece will fit and offer protection on all acoustic guitars that have round sound-holes.
I now have a provisional patent, and plan to go forward with obtaining a final patent. I am sure my sound-hole guard product will catch on and appeal to all levels of musicians who can appreciate the need to protect their investment, whether sentimental or financial.

The A. James Clark School of Engineering at the University of Maryland, College Park and Stratasys, Inc., announce the successful design, fabrication, and test of a Webbed Tube Heat Exchanger (WTHX), believed to be the first plastic heat exchanger made by additive manufacturing. Fabricated at the Stratasys facility in Eden Prairie, Minn., the 3D-printed WTHX promises to expand the potential applications of polymer heat exchangers to small production volumes and cost-constrained systems.
The WTHX represents the first time that a plastic heat exchanger has been manufactured through Stratasys' Fused Deposition Modeling (FDM®) technology and used to successfully transfer heat through a polymer structure from a hot gas to a cold liquid. Room air, heated to 120 degrees Celsius was cooled by building water at 27 degrees Celsius, transferring nearly 65W of heat in the 500 cubic centimeter heat exchanger.
Juan Cevallos, a Ph.D. candidate and research assistant in the Thermal Management of Photonic and Electronic Systems (TherPES) Laboratory at the Clark School's Department of Mechanical Engineering, was responsible for testing the WTHX. Under the direction of Professor Avram Bar-Cohen-along with Professors S. K. Gupta, David Bigio, and Hugh Bruck-Cevallos has been working in collaboration with the Petroleum Institute in Abu Dhabi to advance polymer heat exchanger technology for seawater cooling of liquified natural gas processes, among other applications. The relatively high tool and assembly costs of low-volume polymer molding production led Bar-Cohen's research team to select an additive manufacturing technology that could build complex geometries in a single step. Stratasys' FDM technology provides that capability while using some of the strongest and most heat-resistant thermoplastics found among additive manufacturing technologies.
The WTHX geometry consists of a stack of rectangular flat plates, each containing an array of tubes that span the length of the plate and are separated by short webs. The tubular array carries the water, while the air flows in the gaps between the rectangular webbed-tube plates. The diameter of the tubes is selected to reduce the power required to pump the liquid while creating a "bumpy" surface on the gas-side that enhances heat transfer between the gas and liquid streams. Moreover, most of the heat transfer occurs directly across the thickness of the WTHX tubes, minimizing the deleterious effect of the low thermal conductivity of the polycarbonate resin.

A remarkable team of plastic surgeons, led by Prof. Blondeel at the University Hospital of Ghent, have successfully executed Belgium’s first full face transplant. Although it was the world’s nineteenth face transplant, this was the first time that the complex procedure was fully planned using digital planning and 3D printing. During the 20 hour long procedure the patient, who suffered from a large facial defect, received bone, muscles, veins, nerves, and of course skin from a donor who had just died.
Pre-operative planning for both the donor and the recipient was completed in collaboration with Materialise CMF (cranio-maxillo facial) clinical engineers using ProPlan CMF. Using CT data, a digital representation of the patient’s anatomy was created and used in the formation of a detailed plan for this complex procedure. In order to put the surgical plan into action, anatomical models and patient specific surgical guides were 3D printed for use before and during the operation. The anatomical models allowed the surgeons to see below the skin of both the patient and the donor and carry out advanced preparation. The 3D printed guides were used during the procedure itself to aid the surgeons and allow them to realize the surgical plan they had created.
The entire CMF team at Materialise is proud of the contribution they have made to this incredible milestone in Belgian medical history.
Materialise would like to congratulate the team of 65 surgeons and medical staff at the University Hospital of Ghent for successfully completing this remarkable procedure. This is an incredible achievement, even more so given that the patient is already making a recovery that surpasses expectations; regaining the ability to speak only 6 days into recovery.
For those that understand Dutch, a video interview is available outlining the procedure at: www.deredactie.be/permalink/1.1191529
In the first four years after Industrial Plastic Fabrications (IPF) bought its first Objet 3D printer, IPF’s rapid prototyping business sky-rocketed from 0 customers to 360. Now, another four years on, the UK-based service bureau continues to rely on Objet 3D printers, and its rapid prototyping business has continued to grow at a very healthy pace.
Today, IPF offers a broad range of machining and fabricating services using varied technologies, but all its rapid prototyping work is produced by its two Objet 3D printers – an Objet Connex500 multi-material 3D Printer for printing parts and assemblies made of multiple different materials on the same print job and for simultaneously printing of multiple different, multi-material parts; and an Objet Eden350V Professional 3D Printer.
“With Objet, we can turn models around quickly, efficiently and with consistency,” says Gary Miller, Head of 3D Printing and Rapid Prototyping at IPF. “And our clients like it that they can get a very clear idea of their final product, due to the high accuracy and the model quality and the combination of different materials in a single model.”
According to Miller, the results are nothing short of amazing. When Miller showed a customer a bicycle chain with interlocking, moveable pieces that had been printed in a single run on the Objet Connex multi-material 3D printer, the customer immediately asked how long it took to assemble. Miller told him: “There’s no assembly. It’s printed in one go; you clean it and then you can move it.”
Being able to simultaneously print numerous multi-material parts made of different material properties is highly valuable to IPF. Miller says: “We can print parts that are 40 Shore, 50 Shore, 95 Shore, rigid and flexible parts – all in one go. Four or five customers can want models with different materials and we can print them on the bed at the same time, thanks to Objet’s unique multi-material Connex technology.”
Much of the 3D printing work at IPF takes place overnight or over the weekend, completely unattended. Before leaving the office in the evening, the operator simply sets the Objet 3D printers to start printing; the next morning, he comes into work, cleans the finished parts, and the parts are ready to be shipped out to customers by the end of day. And it happens day after day, week after week.
“We can’t afford for our printers to be down at all,” says Miller. “Objet 3D printers are very reliable machines and the only reason we’ve reinvested in Objet is because the service and support when it’s been needed has been phenomenal.”
Industrial Plastic Fabrications Ltd., located in Essex, UK, offers high-quality machined, formed and fabricated plastic components, plus rapid prototyped parts and 3D printing to the very best standard in the industry. Established in 1969, IPF has over 40 years worth of experience to draw from and its expertise is renowned within the industry. The company’s precision machined, fabricated or formed components provide crucial parts for equipment used within the pharmaceutical, medical, aerospace, automobile, security, audio and broadcasting industries.

Scientists at GE Global Research are back in the holiday spirit. As an encore to the redesign of Santa’s sleigh and construction of a state-of-the-art “Toy Lab” for Santa and the elves, researchers are bringing high-tech manufacturing to Christmas tree decorations to ring in the holiday season using additive manufacturing techniques.
Additive manufacturing, or 3-D printing, is the practice of building up material to directly form a net-shape product rather than forming a product by traditional methods such as forging, casting or machining material away. For GE, it is providing new degrees of product design freedom and the opportunity to reduce the time, cost and use of materials that go into making our products.
The 3-D printing process is highlighted in the video shown below. Juan Pablo Cilia, a Rapid Prototyping Specialist at GE Global Research, takes you through the entire process step-by-step from his initial design drawings on the whiteboard to a computer-aided design (CAD) that is the blueprint used to print the ornament itself. In addition, you will see the actual printing of the ornament in action.
“3-D printing techniques are creating beautiful ornaments that would not be possible using traditional manufacturing methods. It’s beginning to look a lot like a ‘3-D’ Christmas,” said Prabhjot Singh, Manager of GE’s Additive Manufacturing Lab. “
“The 3-D Christmas ornaments represent a creative way to showcase the possibilities in additive manufacturing to achieve revolutionary new product designs. At GE, Juan Pablo and members of my team see tremendous opportunities to use these processes to transform and improve the products we make from commercial aircraft engines to medical imaging systems.”
GE already is producing intricately designed parts and components for aircraft engines using additive technologies and has an innovative program in healthcare to simplify and reduce the cost of how ultrasound probes are made. Members of the Additive Manufacturing Lab are exploring new frontiers to expand the application of 3-D printing techniques across GE’s business portfolio.
Singh said, “As 2012 rapidly approaches, members of GE’s Additive Manufacturing Lab are looking forward to a very active year ahead. We will be hosting a technology summit on Additive Manufacturing, bringing in key stakeholders and thought leaders from industry, academia and government to discuss the future of this emerging manufacturing trend. We have only just begun to tap into its vast potential.”

Capturing the beauty of Vienna’s imperial nostalgia in an impressive 3D scale model has proven to be a stunning project for Materialise, no matter which way you look at it.
Urban planners have turned to 3D printing to help them in the rejuvenation process of some districts of the city. A scale model of one such renewal project, the Morzinplatz-Schwedenplatz, was on display in Vienna’s Museum Karlsplatz in an exhibition called ‘Space for the city’. Its purpose was not simply to show how beautiful this inner-city development along the Danube Canal could be. It also highlights potential development ideas and encourages a conversation with the public about the new Raiffeisen building proposed in the area.
With such a lofty purpose in mind, it was important for planners to give people the most realistic and accurate representation of the project as possible. That’s why the City of Vienna (Magistrat der Stadt Wien) approached Materialise.
Couldn’t be created in any other way
Based on design files collected from photos taken from a plane, a matrix was used to prepare the data. Cut into 21 pieces, the 1,220 mm X 900 mm replica was then printed on a Z Corporation printer, the only 3D printer able to print in colour.
“It was certainly a challenge to prepare the data of this extensive project, but thanks to our experience we were able to create a highly-detailed, good quality product which is aesthetically appealing,” explains Josef Kurz, Branch Manager at Materialise Austria. “Not a lot of companies could manage such a project in such a short time.”
Highly-detailed, stunningly beautiful
Thanks to the accuracy and resolution of the ZPrinter, details were represented in colour with a high degree of precision. Now people can see what the proposed building and area will look like so there will be no surprises.

Engineering scientists at the University of Southampton are developing the world’s first fully rapid prototyped air vehicle this week, to help develop new technologies that probe the Earth's atmosphere using an unmanned platform.
The vehicle is part of the ASTRA (Atmospheric Science Through Robotic Aircraft) project, and it aims to demonstrate how a low-cost, bespoke high altitude platform could be developed and manufactured over a period of mere days and used to send a payload with atmospheric monitoring equipment into the upper atmosphere.
The entire structure of the balloon-borne pod – dubbed the ASTRA Atom -- has been printed, and the on-board data logging equipment has been built using Microsoft's rapid electronic prototyping toolkit .NET Gadgeteer. The Atom was printed on the University’s 3Dprinter, which fabricates plastic objects, building up the item layer by layer.
The aircraft is protected by two foam ‘orbits’, manufactured using a computer-controlled hot wire cutter at the University’s Engineering Design and Manufacturing Centre, which are designed to break on landing and absorb the energy of the impact.
Dr András Sóbester, University of Southampton Lecturer and a Royal Academy of Engineering Research Fellow, says: “The rapid prototyping of bespoke platforms like the ASTRA Atom enables scientists to deliver a variety of instruments far into the stratosphere after a very short design and manufacture cycle. This may be required for testing purposes, as part of an iterative development process or there may be a sudden need to make observations of phenomena such as volcano eruptions or nuclear fallout. In such cases, rapid prototyping translates into fast response and timely measurements that could not be obtained in other ways.”
Dr Steven Johnston, from the University of Southampton’s Microsoft Institute of High Performance Computing, adds: “The challenges of developing such systems are varied as the aircraft has to be able to operate in the harsh, low pressure, low density environment of the upper stratosphere, as well as in the dense and turbulent lower troposphere. Additionally, weight and power requirements of all on-board systems have to be minimised. The need to keep weight and cost to a minimum, while providing bespoke architectures demands novel manufacturing technologies, such as 3D printing, too.
“Using conventional materials and manufacturing techniques, such as composites, developing such platforms would normally take months. Furthermore, because no tooling is required for manufacture, radical changes to the shape and scale of the ‘pod’ can be made with no extra cost.”

3D printer maker Stratasys said its Dimension 3D Printing technology created several of the physical models for the popular stop-motion animated short “Back To The Start,” which has garnered more than two million YouTube views and a nod from AdWeek as one of the top commercials of the year.
Produced for Chipotle Mexican Grill by CAA Marketing Group and Nexus Productions, “Back To The Start” features a stop-motion animated trip from farm to table, punctuated by a soulful Willie Nelson cover of Coldplay’s “The Scientist,” specially commissioned for the video.
The film, by filmmaker Johnny Kelly, depicts the life of a farmer as he slowly turns his family farm into an industrial animal factory before seeing the error of his ways and opting for a more sustainable future. Both the film and the soundtrack were commissioned by Chipotle to emphasize the importance of developing a sustainable food system.
London-based special effects studio Artem, Ltd. produced the visual effects for the video, which has won praise for its creative approach to telling Chipotle’s sustainability story. During the past five years, Artem has used the Dimension 3D Printer to produce models for dozens of clients, including the British Broadcasting Corporation (BBC), 20th Century Fox and Nokia.
“The beauty of using the Dimension 3D Printer for this project was that we could produce exact replicas of the animatic drawings, rather than guessing about sizes and details as we might have done with hand-sculpted models,” said Bob Thorne, senior visual effects supervisor for Artem, Ltd.
With an approved animatic (a design file with rough-draft, full-motion sketches of proposed animated sequences), Thorne and his team had only to feed that data to the Dimension 3D Printer before producing and hand-finishing the models, most of which were human-inspired characters that required a high level of detail.
Using traditional production methods, these models might have taken days to sculpt by hand and finish to the director’s specifications. But with the Dimension 3D Printer, Thorne and his team completed the process overnight and produced a tray full of models.
“Back To The Start” has won praise from creative arts leaders, sustainability experts and pop culture gurus for its fresh, engaging approach to the subject of factory farming and food quality. A “making of” video – which includes the Dimension 3D Printer – has garnered its own YouTube following, with more than 20,000 unique views.
Kraftwurx is not a simple manufacturing company making custom products, it’s a revolutionary new way to print the planet in 3D. Kraftwurx is a social community for artists, engineers, designers and anyone with an idea where your ideas are made into products, printed in 3D and sold to the world as real products.
Kraftwurx is partnering with 3D printing companies around the globe, creating the worlds first and only networked manufacturing system of 3D printers, ready to make products and ship them to your door. We currently have over 600 bureaus and 40+ materials in our network and it is growing every day! Kraftwurx also provides an outlet for creative people to make money because products on Kraftwurx are designed by community members and sold on the site.
As an educational tool for 3D design and printing, Kraftwurx has a lot to offer. The site is available in 58 languages and has a real-time chat system in your own language. The site also features a Facebook-like social platform designed exclusively for those interested in learning about 3D printing and selling products.
Kraftwurx is a very efficient and cost effective way to bring products to market. Every product for sale on Kraftwurx is stored as a 3D model (or an assembly of models) and produced through 3D printing only when a customer orders something from the site. Products are drop shipped directly to the customer. The software that powers Kraftwurx makes decisions on where to produce your product when you order it. It looks for the closest facility to you that can make your item. This saves time because the items will often be made locally. As a business owner, it is not difficult to see that the business model has merits.
It’s a compelling business model which reduces the need for transportation and fuel, because products are made near the end user. It also eliminates the need for inventory and warehouses because products are stored as 3D models until someone orders an item. Early next year, Kraftwurx will be adding the ability for customers to customize and personalize many of the products for sale in the site.
Satisfied business owners and end customers are the result of all this because consumers get custom products that meet their unique needs quickly, and cheaply and businesses are able to bring new products to market without the need for their own supply chain and warehouses.
Kraftwurx has amassed a network of several hundred 3D printer facilities globally and the number is growing. The trend reflects the movement back to more localized manufacturing. As this trend continues, consumers will notice more products available with Kraftwurx & Digital Factory at the epicenter of the movement. Kraftwurx is currently experiencing traffic from 86 countries & territories around the world. The sites traffic is increasing by 3000% monthly.
Kraftwurx is based on a business model developed in 2005 and patented in 2006 by Digital Reality. In 2006, the company launched a beta website to showcase the idea and raise capital. Work has continued quietly ever since. Digital Reality has been monitoring the market which, has gradually developed into a working method to make real products, without a factory and costly labor force and they felt the timing was right to make the announcement.
In 2004, Chris Norman, a Manufacturing Engineer from Texas A&M University and avid 3D designer realized that 3D printers were maturing enough to be used for the consumer products market but enabling technologies did not exist. He began work on the system that powers Kraftwurx through a patent called “Made-To-Order Digital Manufacturing Enterprise” and turned it into a factory-in-a-box that you can purchase much like you would buy Microsoft Office. It enables you to open a web-based store where the products are 3D models until purchased and then printed in 3D without any additional software or services. It includes a system that enables consumers to customize and personalize their own products and see what they are buying in 3D on their computer at work or home.
The Kraftwurx community is wrapped around Digital Factory™ which allows the community members to upload their 3D models in a sellers account and sell them to anyone around the world.
Even users with little or no experience in 3D design can turn an idea into a product and earn money from it. Kraftwurx has a system called Alchemy where an idea can be posted. Other community members can assist in the product’s 3D design and development. Compensation can then be negotiated in terms of actual cash or potential profit from future sales of the finished design. With Alchemy, 3D experience is not necessary.
Kraftwurx is easy to use for everyone, whether you are a designer, seller or a 3D printer and the community brings everyone together, regardless of nation or language.

Released this October, Real Steel is an American science fiction action film starring Hugh Jackman and directed by Shawn Levy. The film is based on the premise that by 2020 the sport of boxing is no longer played by humans, but robots.
To make the robots as real as possible for the film, Legacy Effects used an Objet 3D printer to produce the 1/5th scale models. Once built, hand-painted, lit, and approved, the full scale Atom, Noisy Boy, and Ambush robots went into production. Motion capture technology was used to depict the fights on camera, mixed with the full scale animatronic robots.
Legacy Effects’ Senior Systems Engineer, Jason Lopes says of the Objet 3D printer, “Being able to print high resolution models on the 3D printer allowed Legacy's designers to go from concept, to final design and into full size production in the shortest possible time.”
Legacy Effects uses Objet’s 3D printers to create a range of scale models and even functional custom parts that have been used in films such as Jurassic Park 3, Iron Man 2 and Avatar. Objet’s 3D printers have also proven instrumental in producing stop-motion animations films, such as Coraline.
“It is a pleasure and an honor to be working with customers such as Legacy Effects and to see our 3D printers helping to produce the very latest effects for some of the most popular Hollywood blockbusters,” said Gilad Gans, Executive Vice President at Objet. “The accuracy, material versatility and surface quality of Objet’s 3D printers allow artists to capture all the nuances and fine details of their ideas and transform them into 3D models that look fully believable under the camera’s lens.”
3D printing represents an important factor in the film industry today, where special effects and technical enhancements often come at the cost of increasing time delays. Using 3D printing allows studios to save on reshoots, editing and post production – enabling a faster time-to-market and lower overall costs.

Following a year packed full of new 3D printing product and material launches, Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, will showcase some of the real-life applications made possible with its technology at EuroMold 2011. A standout highlight of the exhibition will be a stunning 3D printed dashboard from StreetScooter.
The StreetScooter project is a consortium of over 80 companies, united with an aim to develop an affordable electric car with an emphasis on sustainability. Working closely with the group, Objet has produced highly realistic prototypes for the development of the style and function of the car, including a 1.4 meter wide dashboard made from over 20 individually printed parts. Major parts of the dashboard were printed in the Objet ABS-like Digital Material, chosen for its exceptional dimensional stability and toughness. Additional Objet materials were used to simulate fine-details. The parts were then glued, polished and painted to precisely simulate the true look, feel and function of the dashboard.
EuroMold visitors can see the fully-assembled dashboard complete with display screens and additional 3D printed fittings at the Objet stand. Also featuring at the exhibition will be a diverse range of exceptionally realistic prototypes, all real applications from Objet customers including automotive and defence parts, kitchen utensils, film special effects, medical devices, dental veneers, footwear and more.
"Objet has a comprehensive range of products for the professional user. From entry-level Desktop 3D printers, to the highly productive Eden range and the unique multi-material Connex series, there's a perfect fit for any product designer or engineer with a rapid prototyping requirement," states Gilad Gans, Executive Vice President for Objet, "It's the 3D printing materials that provide many of the unique capabilities of our 3D printers. With the introduction of several important new materials in 2011, Objet can now boast an impressive portfolio of 68 materials of varying physical and mechanical properties. It's the most versatile range of materials on the market, all developed with the intention to create the most realistic prototypes possible."

Spiders are very agile, and some can even jump. They owe this capability to their hydraulically operated limbs. Researchers have now designed a mobile robot modeled on the same principle that moves spider legs. Created using a 3-D printing process, this lightweight can explore terrain that is beyond human reach.
Enviably agile and purposeful, the mobile robot makes its way through grounds rendered off-limits to humans as the result of a chemical accident. Depressions, ruts and other obstacles are no match for this eight-legged high-tech journeyman. Its mission: with a camera and measurement equipment on board, it will provide emergency responders with an image of the situation on the ground, along with any data about poisonous substances. Not an easy task; after all, it must be prevented from tipping over. But this risk seems a minor one as it confidently and reliably picks its way through the area. As a real spider would, it keeps four legs on the ground at all times while the other four turn and ready themselves for the next step. Even in its appearance, this artificial articulate creature resembles an octopod. And no wonder – the natural specimen provided the model for researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA. This high-tech assistant is still a prototype, but future plans envision its use as an exploratory tool in environments that are too hazardous for humans, or too difficult to get to. After natural catastrophes and industrial or reactor accidents, or in fire department sorties, it can help responders, for instance by broadcasting live images or tracking down hazards or leaking gas.
With its long extremities, the spider has a range of ways to get around. Some models can even jump. This is possible using hydraulically operated bellows drives that serve as joints and keep limbs mobile. With no muscles to stretch their legs, these creatures build up high levels of body pressure that they then use to pump fluid into their limbs. Shooting fluid into the legs extends them. “We took this mobility principle and applied it to our bionic, computer-controlled lightweight robot. Its eight legs and body are also fitted with elastic drive bellows that operate pneumatically to bend and extend its artificial limbs,“ explains Dipl.-Ing. Ralf Becker, a scientist at IPA. The components required for locomotion, such as the control unit, valves and compressor pump, are located in the robot‘s body; the body can also carry various measuring devices and sensors, depending on the application at hand. Hinges interoperate with the bellows drives so that the legs can move forward and turn as needed. Diagonally opposed members move simultaneously, too. Bending the front pairs of legs pulls the robotic spider‘s body along, while stretching the rear extremities pushes it.
The special aspect of this high-tech helper: not only very light, it also combines rigid and elastic shapes in a single component; with just a few production steps, it can also be produced at low cost. To date, designs such as the mobile robot have been generated using conventional mechanical-engineering technologies – a time-consuming and costly undertaking. Researchers at IPA, on the other hand, rely on generative production technologies, and specifically on selective laser sintering (SLS) of plastics, a 3-D printing process. In this process, step by step thin layers of a fine polyamide powder are applied one at a time and melted in place with the aid of a laser beam. This way, complex geometries, inner structures and lightweight components can be produced – with structures optimized much as if produced by Nature herself. The experts at IPA have a great deal of latitude in the design of their mobile robot; the leg modules, for instance, can be designed with infinitely variable load-bearing characteristics.
“We can use SLS to produce one or even several legs in a single operation; this minimizes assembly effort, saves materials and reduces the time it takes to build a robot. With the modular approach, individual parts can be quickly swapped as well. Our robot is so cheap to produce that it can be discarded after being used just once – like a disposable rubber glove,“ Becker points out. A prototype of the robot can be seen at the EuroMold 2011 trade fair in Frankfurt, at the joint stand of the Fraunhofer-Gemeinschaft (Hall 11, Stand C66), from November 29 through December 2.

We at Materialise are honored to have worked on the breath-taking Sagalassos exhibition taking place at the Gallo-Roman museum in Tongeren from 29/10/2011 to 17/06/2012. Together with the research team from the KU Leuven and those who the discovered the ruins, we were able to 3D print this massive yet intricate scale model of the Greek-Roman city exactly as it was at the height of its glory.
3D printing is the ideal technology for accurately reproducing models to this scale and complexity. For those familiar with Google Street View, you will understand that it is now possible to create 3D reproductions of the buildings around us on a computer for others to see and enjoy. 3D printing allows these reproductions to be built layer-by-layer, using lasers and in this case a liquid resin, for a high quality result.
As experts in 3D printing, we sat down with the project team to discuss how best to realize this incredible project. Which details could be built? To what dimensions could we go? In which manner would the 3D files from the archeological site be best handled? After these important decisions were made and the final 3D file were delivered to Materialise, we were able to use our Magics software in order to easily optimize the file in order to prepare it for production.
We printed the scale model on one of Materialise’s own patented Mammoth machines, the largest stereolithography machines in the world, on which parts larger than 2m can be build in one piece. A special material called Protegen was used, which is a liquid epoxy perfectly suited for this 3D printing method. For stereolithography, a thin layer of liquid is spread over a large platform and lasers are used to harden the liquid according, much like the laser printers in our houses. The only difference is that in this case, hundreds if not thousands of layers are drawn and connected, one of top of another to create a 3D object. At the end, the object rises from the machine and the unused liquid flows away.
To finish the piece, the scale model was covered in a protective white coating. Due to the impressive size of the scale model, it was printed in several pieces and still, only 15 days were required in order to bring Sagalassos back to glorious life.

Stratasys Inc. today announced that it will be exhibiting the much publicised Urbee eco-car at this year's Euromold event in Frankfurt. Urbee is the first prototype car ever to have its entire body 3D printed. Stratasys will also host an aerospace stand at the exhibition, which will feature rapid prototyped and end-use parts in situ to illustrate how the commercial aircraft and the defence industries rely on FDM technology.
Urbee, which stands for Urban electric with ethanol backup, is a two passenger vehicle that was designed with sustainability in mind. It requires just an eighth of the energy used by conventional cars and is capable of reaching up to 200mpg (approx 85 km/l) on the highway and 100mpg (approx 43 km/l) in the city. The body of the prototype which will be on display was created using Stratasys' Dimension 3D printers and Fortus production systems. Urbee's creators, Kor Ecologic will be on the stand (D132, Hall 11) to answer questions.
The aerospace (C111, Hall 11) stand will feature a 10% scale model of a finished Unmanned Aerial Vehicle (UAV), a mock-up cockpit display panel and yoke as well as a number of examples of Stratasys technology in aerospace-related applications. Members of the digital manufacturing team will also be on the stand.
"We are very excited about bringing Urbee to Euromold and are looking forward to hosting our first ever aerospace stand," said Tim Heller, MD of Stratasys Europe. "Both stands will demonstrate the capabilities of our 3D printing technology and the fantastic results that can be achieved. We expect visitors to be pleasantly surprised by the accuracy and quality that our machines can produce in such a short space of time."

A Swedish creative studio has used Z Corporation 3D printing technology to create a stunningly detailed 3D architectural model that is helping promote Stockholmsarenan until the 30,000-seat sports and entertainment arena is completed in 2013.
Thanks to the accuracy and resolution of the ZPrinter® 450 owned by the WE DO studio, virtually every detail in the architects' 3D digital model of the arena is represented in the physical model, a cross-section that includes 7,400 highly detailed seats, each 4 mm wide.
"Stockholmsarenan is a monument to world-class sports and entertainment, activities that can stir passion like few others," said Patrik Lindberg, owner of WE DO, based in Stockholm. "Until the arena is complete, this ZPrinted model is helping generate the excitement for the arena, helping the owner and operator rent the space, sell seat licenses, plan events and entice sponsors – in other words, make the business a success."
The 1.2-meter-by-1.2-meter model is the centerpiece of an information pavilion offering a multimedia experience of the project. Both the architect and prospective patrons are "blown away" by the piece, said Lindberg.
3D printing speed, color and affordability dictated the choice
Much as a document printer converts a word-processing file into a business letter, 3D printing converts 3D digital data into a physical model you can hold in your hands. "We chose to ZPrint this model because it creates a model faster, more affordably and more accurately than handcrafting," said Lindberg. "We worked toward a tight deadline and printed different sections of the model nonstop for two weeks. It would have taken us at least three times more time and money to make this by hand, and the result would have been far less detailed. In other words, ZPrinting made this project a success."
Lindberg, a trained industrial designer, uses ZPrinting constantly to create product prototypes for design clients and models for architects. Although Stockholmsarenan was ZPrinted in classic architectural white, clients are increasingly asking for color, according to Lindberg. "Companies are becoming enlightened on the possibilities for rapid prototyping," he said. "Color, in addition to speed and cost, are why we selected the ZPrinter."
ZPrinters are the only 3D printers capable of simultaneously printing in multiple colors. They are the fastest in the industry and have the lowest operating costs, automatically recycling and reusing all material that isn't used for the model.

This Old House, the beloved public TV series for home renovation enthusiasts, will use a highly detailed 3D printed architectural model from Z Corporation to communicate planned improvements to a historic Bedford, Mass., homestead once owned by a prominent Revolutionary War figure, Nathaniel Page. The model will be featured in the Oct. 6 and Oct. 13 episodes, and make other appearances during the 16-episode season (check local listings or www.thisoldhouse.com/tvschedule for dates and times in your area).
The 14-piece multicolor physical 3D model – 28 inches x 21 inches x 9 inches – can be assembled in two ways, depicting the Nathaniel Page Homestead before and after two additions and a thorough renovation. The model includes removable rooftops and second floor, and a fully detailed interior.
"The 3D model powerfully communicates the architect's vision for the finished home before we pry off the first clapboard," said Dan Quaile, the architect for the This Old House Bedford Project. "The designers, contractors, viewers and homeowners get a much clearer image of the project than they could through 2D plans and conversation alone."
This Old House plans to use more of Z Corporation's models down the road, most immediately for their next project in Barrington, R.I.
The story of 3D printed models communicating design intent for building professionals, their clients, and other stakeholders is a familiar one as architects have begun discovering the ability to quickly create physical 3D models that are more highly detailed, accurate and affordable than handcrafted models. ZPrinted models can be printed in traditional architectural white or in full color.
Z Corporation 3D printers create physical objects from 3D design files much as document printers create business letters from word-processing files. ZPrinters are the only 3D printers capable of simultaneously printing in multiple colors.
The Nathaniel Page Homestead belongs to Rebecca and Joe Titlow. Joe is Z Corporation's vice president of product management and in one of the episodes explains to host Kevin O'Connor how 3D printing works. "It was a lot of fun to bring my work home with me this time," he said. "I was thrilled that the crew was able to use the model."

MAKE Eyewear is peering into the future with the launch of its new eyewear collection and Freestyle design service. The company offers unique designs and virtually unlimited customization, and is able to do so because it employs a revolutionary production method known as 3D printing.
The technology used to print three-dimensional objects has been around for a few decades now, but it has only recently attained a level of quality necessary for making end consumer products. It is still rare to find anything which is manufactured using this process, primarily because it tends to be much more expensive than traditional production methods. However, since cost is based on the amount of material consumed and not design complexity, it is reasonable to produce small products like eyewear.
Founder David Minich states, "There are some really interesting 3D printed objects out there, but many of them do not really make much sense to me as products. A basic 3D printed chair, for example, can easily cost thousands of dollars. That's a lot of money for a plastic chair." Sticking with a relatively small product that does not require a large volume of material, has allowed the company to keep prices competitive with other, non-3D printed, glasses on the market. What's more, each frame style in the online store is available in three standard sizes and can be customized further to provide an even better fit.
In addition to the frames offered in the online store, customers can design their own glasses from scratch using the "Freestyle" service. MAKE provides as much or as little assistance in the design process as a customer wants, and a frame can be designed from something as simple as a rough sketch.

The unveiling of the first prototype URBEE, with its completed body, occurred at the TEDxWinnipeg event on September 15th at the Winnipeg Art Gallery (WAG). The unveiling was a milestone for Urbee as they are a small group of designers and engineers in Winnipeg. Jim Kor, owner of Kor Product Design presented 'Rational Automotive Design for the Human Race' at TEDx. The event featured 8 speakers, each doing a TED Talk (18 minutes each, ... IDEAS worth Sharing). The car was unveiled in the lobby and was the first time the finished 3-D printed body was shown. This is still a prototype and only 1 car like this exists.
Frequently Asked Questions
Question: Would you see 3D printing as a viable production method for a commercial proposition, or was that simply used for prototyping?
Answer: When we started our partnership with Stratasys, in Minneapolis (the company that 3-D printed our body), we had in mind that this process would be used ONLY for prototyping. The 'we' I am referring to is our Urbee Team. People within Stratasys have been working very hard at making this process a viable production method (called 'digital manufacturing'). I now believe that this is indeed a viable production method. 3-D printing has many advantages. From a design point of view, just to name a few advantages:
1) There is no hard tooling required, the designer is essentially free to place the material wherever it is needed, and each production part can be made unique.
2) This process could revolutionize how we make things. It has certainly changed my way of thinking about manufacturing.
3) Just as an aside: The SAME computer files that made the scale model were used to make the full-size body panels. This way, we knew the big panels would all fit properly (the model was a test).
Question: Might we ultimately get to the point where Urbee body designs could be made available for download then locally produced?
Answer: This process of 3-D printing turned into 'digital manufacturing' would change the way we replace parts within machines. You would have an inventory of computer files on hand, stored somewhere in the world, and utilize the closest 3-D printing facility available to the machine that needs the repair part.
Question: What environmental considerations are made as part of the production process?
Answer: Environmentally this process holds promise because one only puts material where one needs it. It is an additive process, building the part essentially one 'molecule' of material at a time, ultimately with no waste. This process can do many materials, and our goal would be to use fully-recycled materials.
Question: When will we see people driving them on our roads?
Answer: There are many people in the world now working with this process of 3-D printing, and they are doing some amazing, mind-bending things. Stratasys is at the leading edge of this. Regarding our car, this car that you now see runs, and it does have a 3-D printed body. We plan on building a second car that would more fully utilize this 3-D printing process throughout the body, interior, and even parts of the chassis.
Question: When will we all be driving one?
Answer: I don't know. All I know is that I personally will very likely be driving, on the road, in a prototype car with a 3-D printed body by 2012. Which is pretty amazing. Regarding when a production Urbee would be available for sale ..... I am a Mechanical Engineer, so I am quite conservative, but, I believe best-case scenario would be 2014. This would be the first practical, roadworthy car that could run on solely Renewable Energy.

A selection of 3D printed objects, manufactured by Belgium’s own Materialise, will be on display throughout the Victoria & Albert Museum as part of the London Design Festival which runs from the 17th till the 25th of September, 2011.
Curated by the world-renowned Murray Moss, the exhibition will show a range of 3D printed objects produced at Materialise’s Belgian headquarters and created by both established and up-and-coming artists, architects, and designers working in the UK, USA, France, The Netherlands and Denmark. Designers include Stephen Jones, Patrick Jouin, Iris van Herpen, and many others, Several of the works to be shown have already been acquired by leading museums, including the Centre Pompidou, Paris, and the Museum of Modern Art and the Metropolitan Museum of Art, New York.
Murray Moss has this to say about the exhibition “We are witnessing an ‘Industrial Revolution 2.0’.
Radical advances in digital and laser technologies, initiated by industry leader Materialise, Belgium, and applied to what is currently referred to as Additive Manufacturing, allow for the three-dimensional ‘printing’ of objects, a sophisticated fabrication process once reserved for prototyping but which is quickly becoming ubiquitous and is profoundly permeating all areas of our contemporary material world, including fashion and domestic furnishings, as well as transportation, medicine, and architecture.
To emphasize the ‘viral’ nature of this Revolution, I have commissioned eight designs from the worlds of fashion and furnishings – all sponsored and produced by Materialise – which were chosen because they respond directly to corresponding masterworks in the Museum’s collection, and/or to prominent locations within the V&A, which I have visited regularly over the past 50 years. My aim was to initiate little ‘narratives’ – some of which I hope will amuse – between certain of the Museum’s historical holdings and these ‘futuristic’ contemporary objects, not only shedding new light on the Museum’s collection, but, in the process, demonstrating the wide reach of these new technologies.”
The excitement is shared by Materialise CEO Wilfried Vancraen, who states, “It is a great honor for us at Materialise to be so involved in the V&A’s first exhibition dedicated entirely to 3D printing (also known as additive manufacturing) and we are proud to be recognized for our expertise in this industry. We truly believe that this technology has the potential to make the world a better and healthier place, and we have made it our mission to make this a reality. We expect the technology to change design, production, distribution and consumption radically.”
Murray Moss’s New York City gallery, Moss (www.mossonline.com), is renowned for its promotion of established and cutting edge design and has been labelled the ‘best design store in the world’ by The International Herald Tribune. He has a long relationship with Materialise, offering many of their works through his celebrated gallery. It is thanks to Materialise’s patented Mammoth machines, the world’s largest stereolithography machines, that larger designs, such as the Fractal.MGX which is featured in the exhibition, can be produced in a single piece.

Researchers have been working at growing tissue and organs in the laboratory for a long time. These days, tissue engineering enables us to build up artificial tissue, although science still hasn’t been successful with larger organs. Now, researchers at Fraunhofer are applying new techniques and materials to come up with artificial blood vessels in their BioRap project that will be able to supply artificial tissue and maybe even complex organs in future. They are exhibiting their findings at the Biotechnica Fair that will be taking place in Hannover, Germany on October 11-13.
There were more than 11,000 persons on the waiting list for organ transplantation in Germany alone at the beginning of this year, although on the average hardly half as many transplantations are performed. The aim of tissue engineering is to create organs in the laboratory for opening up new opportunities in this field. Unfortunately, researchers have still not been able to supply artificial tissue with nutrients because they do not have the necessary vascular system. Five Fraunhofer-institutes joined forces in 2009 to come up with biocompatible artificial blood vessels. It seemed impossible to build structures such as capillary vessels that are so small and complex and it was especially the branches and spaces that made life difficult for the researchers. But production engineering came to the rescue because rapid prototyping makes it possible to build workpieces specifically according to any complex 3-D model. Now, scientists at Fraunhofer are working on transferring this technology to the generation of tiny biomaterial structures by combining two different techniques: the 3-D printing technology established in rapid prototyping and multiphoton polymerization developed in polymer science.
A 3-D inkjet printer can generate 3-dimensional solids from a wide variety of materials very quickly. It applies the material in layers of defined shape and these layers are chemically bonded by UV radiation. This already creates microstructures, but 3-D printing technology is still too imprecise for the fine structures of capillary vessels. This is why these researchers combine this technology with two-photon polymerization. Brief but intensive laser impulses impact the material and stimulate the molecules in a very small focus point so that crosslinking of the molecules occurs. The material becomes an elastic solid, due to the properties of the precursor molecules that have been adjusted by the chemists in the project team. In this way highly precise, elastic structures are built according to a 3-dimensional building plan. Dr. Günter Tovar is the project manager at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB based in Stuttgart. When we caught up with him, he described the latest work: The individual techniques are already functioning and they are presently working in the test phase; the prototype for the combined system is being built.
When ink becomes an artificial vessel system
You have to have the right material to manufacture 3-dimensional elastic solids. This is the reason why the researchers came up with special inks because printing technology itself calls for very specific properties. The later blood vessels have to be flexible and elastic and interact with the natural tissue. Therefore, the synthetic tubes are biofunctionalized so that living body cells can dock onto them. The scientists integrate modified biomolecules – such as heparin and anchor peptides – into the inside walls. They also develop inks made of hybrid materials that contain a mixture of synthetic polymers and biomolecules right from the beginning. The second step is where endothelial cells that form the innermost wall layer of each vessel in the body can attach themselves in the tube systems. Günter Tovar points out that »the lining is important to make sure that the components of the blood do not stick, but are transported onwards.« The vessel can only work in the same fashion as its natural model to direct nutrients to their destination if we can establish an entire layer of living cells.
Opportunities for Medicine
The virtual simulation of the finished workpieces is just as significant for project success as the new materials and production techniques. Researchers have to precisely calculate the design of these structures and the course of the vascular systems to ensure optimum flow speeds while preventing back-ups. The scientists at Fraunhofer are still at the dawn of this entirely new technology for designing elastic 3-dimensionally shaped biomaterials, although this technology offers a whole series of opportunities for further development. Günter Tovar acknowledges »we are establishing a basis for applying rapid prototyping to elastic and organic biomaterials. The vascular systems illustrate very dramatically what opportunities this technology has to offer, but that’s definitely not the only thing possible.« One example would be building up completely artificial organs based on a circulation system with blood vessels created in this fashion to supply them with nutrients. They are still not suited for transplantations, but the complex of organs can be used as a test system to replace animal experiments. It would also be conceivable to treat bypass patients with artificial vessels. In any event, it will take a long time until we will actually be able to implant organs from the laboratory with their own blood vessels.
This is a project that the Fraunhofer Institute for Applied Polymer Research IAP in Potsdam, Germany, the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart, Germany, the Fraunhofer Institute for Laser Technology ILT in Aachen, Germany, the Fraunhofer Institute for Manufacturing Engineering and Automation IPA in Stuttgart, Germany and the Fraunhofer Institute for Material Mechanics IWM in Freiburg, Germany are all participating in. They are exhibiting a large model of an artificial blood vessel printed with conventional with rapid prototyping technologies and samples of their current developments in Hall 9, Stand D10 at the Biotechnica Fair.

Paramount Industries, Inc., a world-class product development / rapid deployment and manufacturing services company, participated in a ribbon cutting ceremony and press conference at Philadelphia’s Navy Yard on August 27, 2011. The press conference included remarks from Mayor Michael Nutter, Temple University President Ann Weaver Hart, US Navy Chief of Naval Operations Admiral Gary Roughead, as well as other dignitaries and program managers. Jim Williams, Paramount Industries’ President and CEO, presented a commemorative award to CNO Admiral Roughead - a 3D printed replica of the USS United States frigate created using laser sintering.
“Today we are pleased to focus our attention to the history of the US Navy, STEM education programs and the next generation of America’s workforce,” said Williams. “It is an honor to support military leaders, government officials, academia and young students in this capacity.”
USS United States was a wooden-hulled, three-masted heavy frigate of the United States Navy constructed by the Naval Act of 1794. It was larger and more heavily armed than standard frigates of the period. Built at Humphrey's shipyard in Philadelphia, Pennsylvania, the USS United States was launched in 1797 and immediately began duties with the newly formed Navy.
The 3D model was manufactured at Paramount Industries facility for rapid prototyping and additive manufacturing using 3D digital scanning and selective laser sintering, an advanced 3D printing technology. These technologies are currently used to deliver prototypes and customized production-ready parts for the medical device, electronics and consumer products industries. Paramount has rapidly manufactured and deployed critical components to high profile aerospace and defense programs such as the F-35 Joint Strike Fighter, Wolfhound Handheld Threat Warning System and the Honeywell T-Hawk.
The ribbon cutting ceremony celebrated the launch of the Mathematics, Engineering, Science Achievement (MESA) program, a new STEM initiative at Temple University. MESA is an academic preparation program that serves pre-college, community college and university students who are educationally disadvantaged. During the event, Mayor Nutter spoke about the importance of science, technology, engineering and math (STEM) education.
Research studies show a strong correlation between STEM education and competitiveness and economic prosperity. Science, technology, engineering and math graduates and undergraduates are the highly-skilled and professional workers who make future contributions to society and the workforce.
“It is critical for business leaders and government officials to support education programs that promote innovation, encourage young students and move professionals into the technology-driven future,” said Williams. “Breakthrough technologies, such as 3D printing and additive manufacturing, allow for smarter engineering and manufacturing of products designed to protect the nation’s military on the front lines where it’s needed the most. In addition to helping those who protect our liberties and freedoms, additive manufacturing offers significant advantages: it returns the competitive edge to American-based manufacturers, allows businesses to create new jobs and strengthens the US economy.”
Founded in 1966, Paramount Industries, Inc. is among the world's most experienced providers of product development services, including design engineering, additive manufacturing, rapid prototyping, direct digital manufacturing, rapid manufacturing, tooling, urethane casting, injection molding and contract manufacturing. Paramount is AS9100 and ISO 9001:2008 certified and ITAR registered. Paramount holds active memberships with the Additive Manufacturing Users Group (AMUG), Association for Manufacturing Excellence (AME), Association for Unmanned Vehicle Systems International (AUVSI), Keystone Chapter AUVSI, Society of Manufacturing Engineers (SME) and ASTM International (formerly known as the American Society for Testing and Materials). Paramount Industries employs nearly 50 engineers, technicians, program and business managers at its Langhorne, Pennsylvania-based research, development and manufacturing facility.

There are as many ways to interpret 9/11 as there are people who experienced that horrible day, whether up close or at a distance. One man’s preference is documenting Ground Zero, in painstaking detail, before the attack, after the twin towers had fallen, and today, now that the site is being rebuilt.
David Munson’s amazingly detailed three-part model “WTC Triptych” is on display now at the New York City Fire Museum in Manhattan’s Soho district. With each model measuring 17 inches x 17 inches, it was created on a Z Corporation 3D printer, which creates physical objects from 3D data (much as a document printer creates business letters from word-processing files).
“There are many wonderful writings, photos and artwork that interpret 9/11,” said Munson. “I think it’s also important to document the totality of it as objectively, realistically and completely as possible, with a minimum of poetic license and a devotion to detail, on a scale the average person can absorb. These are my strengths, and this is my small contribution to ensuring people never forget.”
Munson, with a background in producing construction documents, owns the Munson3D architectural visualization company, and is a specialist in precise, complex representation. He drew from numerous data sources to create “WTC Triptych,” including 2D satellite imagery, Google Earth, photographs (personal and downloaded from the Internet), publicly available 3D models and Wikipedia, among others. He used Autodesk 3dsMax Design computer-aided design software as well as AutoCAD, Google SketchUp and Adobe Photoshop as auxiliary programs.
“The data was not from one particular source but was cross-checked against multiple sources,” he said. “So I could cross-check a graphics source with skyscraperpage.com, for example, or simply go to Wikipedia to find the numerical height of a building. Also, 3dsMax Design let me extract 3D information from flat photographs as long as there were enough 'known' points. So, I used photos for more than just applying textures on the models. There is no simple way to describe this process other than to say it is very precise for the scale.”
Though extremely labor intensive, gathering the data was only the beginning. The data was then used to create an accurate physical representation. “There is only one way to do it,” said Munson. “I needed the ZPrinter®, which not only accommodates large sizes but, because of its unique color capability, is the only way to accurately reproduce the highly detailed texture mapping used in these computer models. This process creates a whole new medium for city planning, and I hope this exhibit illustrates its potential value to a larger audience.”
Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, announced today that the 'Rapidprototypedshoe' from avant-garde shoe designer Marloes ten Bhomer will hit the spotlight this autumn as part of an exhibition entitled Power of Making, starting today at the Victoria and Albert Museum, London. Produced using Objet multi-material 3D printing, the Rapidprototypedshoe is designed and manufactured in a modular way so that it can be dismantled and reassembled for the purpose of replacing parts.
"My work is very much about liberating design – I use new materials and methods because this helps to break away from conventional approaches," Marloes ten Bhomer explains. "The rapid prototyping process stimulated the idea for this shoe, as the name suggests. I explored the technology and saw that rapid prototyping – adding material in layers – rather than traditional shoe manufacturing methods – could help me create something entirely new within just a few hours."
Further research led ten Bhomer to Objet's Connex range of multi-material 3D printing systems. "Objet Connex printers make it possible to print an entire shoe – albeit a concept shoe – including a hard heel and a flexible upper in one build, which just isn't possible with other 3D printing technologies," states ten Bhomer. "The shoe is printed as a single entity so the parts come off the printer already assembled, and you can still take the shoe apart later on. It is inspiring and opens up the possibility of interchangeable heels and creating customized designs. Also, the possibility of repairs allows for a more realistic product and changes the idea of rapid prototyping into rapid manufacturing."
Objet 3D printing, which can combine rubber-like materials and rigid materials in a single prototype, is used extensively in the footwear industry. By producing more realistic prototypes and encouraging more prototyping and design iterations, Objet's 3D printing solutions enable companies to create better end-products in shorter time and at lower overall cost. Gilad Gans, Executive Vice President of Objet comments, "The highly detailed models produced by Objet provide the benefits of physically reviewing and testing designs that just can't be matched by 2D drawings. As an affordable alternative to factory-produced samples, the process encourages users to review more design alternatives, increasing the potential to produce a more creative or better designed concept."
"Cost-wise it does make sense to use Objet 3D printing, particularly for haute couture shoe design," says ten Bhomer. "I can have prototypes printed in multiple materials with no expensive set-up costs and no minimum quantities. I also have great confidence in the quality of digital prototyping – with conventional shoe mould making, the heel is matched to its left or right counterpart by eye, so there's always room for error and it can be a slow process. By making the moulds digitally you know the left and right shoes are an exact match and it's also economical and easier to scale seven different sized pairs, as required for a commercial line of shoes, using specialist software and Objet 3D printing."
Power of Making is a free V&A and Crafts Council exhibition. Curator Daniel Charny's aim is to encourage visitors to consider the process of making, not just the final results. See ten Bhomer's Objet 3D printed Rapidprototypedshoe at the Victoria and Albert Museum, London, from 6th September 2011 – 2nd January 2012 and visit www.vam.ac.uk/powerofmaking for more information on the exhibition.
Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, will be showcasing its advanced 3D printing solutions at SIGGRAPH's 38th International Conference and Exhibition on Computer Graphics and Interactive Techniques, 7 - 11 August 2011 in Vancouver, Canada.
Objet's newest multi-material 3D printer, the compact Objet260 Connex - based on the company's patented inkjet 3D printing technology and the world's only system able to jet two materials at the same time - will be on display.
Objet will be showcasing Objet-created models from two blockbuster movies: Destroyer, from the 2011 American superhero film Thor and Neytiri of the Na'vi clan from 2009's Academy Award winning movie Avatar. The models are just a few examples of how Objet's technology is used by Legacy Effects - an award winning, full service character design, make-up, specialty prop and animatronic studio - to help bring movie characters to life.
Jason Lopes, senior systems engineer at Legacy Effects, says that rapid prototyping has been integral to their design process since Jurassic Park 3: The Lost World. "From the moment we were introduced to Objet's technology, we knew it would change our business," says Lopes. "Things we had never thought of are possible with this technology. All detail is captured and nothing is ever lost or forgotten in translation. Basically, anything that we can think up, the Objet 3D printers can print within hours."
Objet will also have several extraordinary models on hand to demonstrate the breadth and versatility of its materials, capable of simulating properties ranging from varying grades of rubber to clear transparency, all the way to rigid, ABS-grade engineering plastics. Objet currently has over 60 3D printing materials, including 51 composite materials (Digital Materials), allowing designers and engineers to print typically challenging parts.
Visitors to Objet's booth (934) can view:
* A model motorcycle from the workshop of Orange County Choppers - a New York-based custom and production motorcycle manufacturer featured on Discovery Channel's American Chopper. The motorcycle was built to demonstrate the ability to adhere different Objet materials together to produce a prototype to help the team at Orange County Choppers fully understand the design intricacies of the motorcycle.
* A fully functional skateboard, printed on an Objet Connex multi-material 3D printers which has similar high dimensional stability, thermal resistance, and toughness as ABS-grade engineering plastics, enabling it to repeatedly sustain the weight of a person.
Objet 3D printers use patented inkjet-based technology to jet ultra-thin layers of photopolymer materials onto system build trays, where each layer is cured with UV light. The process delivers models which can be handled immediately, with exceptional accuracy and allowing complex geometry, including thin walls, overhangs and even moveable parts.
Objet's true-to-life models offer unique opportunities for the Animation and Entertainment industry. Objet looks forward to hosting SIGGRAPH attendees at the Objet Booth 934 to experience the latest in 3D printing systems and materials.

The growing community of DIY designers + makers is a phenomenon that has exploded in recent months. The shift away from mass customized products towards individual, personalized goods is a reflection of the changing tide in consumerism and it has been made possible by the increasing accessibility of the tools that allow consumers to design and make the products they want – when they want them.
Personalisation is the creation of a product to meet the specific requirements of an individual. The epitome of personalisation is the creation of one’s own wedding ring, and that is precisely what Cloud9 design software together with 3D printing from i.materialise has achieved for Kari.
Of course it helps if your mum has a background in design and jewellery — but these days it is not an essential factor. This inspiring story, though, is shared to illustrate the potential of original design + make technologies.
Rob proposed to Kari at the end of last year, and her dream engagement ring was one that Kari had seen years earlier, created using traditional techniques by her mum, Ann Marie Shillito who is a jeweller, a 3D design software developer and a self-confessed 3D printing evangelist.
Kari is extremely proud of her mother, saying: “‘I have been so lucky growing up with a jeweller as my mum, some of my earliest and fondest memories are walking through the front door after school to the familiar sound of her hammering away in her workshop.”
Ann Marie now also runs Anarkik3D, a company that has developed Cloud9 — a haptic, organic modelling software package for easy, intuitive 3D design. This original software in combination with the latest developments in 3D printing materials — titanium — meant that the timing could not have been more perfect for Ann Marie to bring all of the necessary threads together to fulfill her daughter’s wish.
The original engagement ring would have been extremely difficult to reproduce for a number of reasons, however, with Cloud9 and 3D printing at her disposal, Ann Marie was able to recreate the design within the software, to be 3D printed in titanium. Furthermore, she was able to design a super fluid titanium wedding ring that flows around the diamond of the engagement ring to create an elegant, personal integrated set.
With the general concept approved by the happy couple the process was set in motion. A test design from Cloud9 was 3D printed in steel for Kari to see and try it on. Following this the full, integrated set was finalised in the Cloud9 software using an accurate digital diamond. On final approval, the wedding ring design was saved and converted to .stl format and sent to I.imaterialise in Belgium to be printed in Titanium. Within two weeks the ring was returned for finishing. With the diamond set in the gold engagement ring the two fitted together perfectly so it looks as though the diamond is floating within the flowing titanium bands.
Kari is absolutely delighted with the results: “I love that my mum made my wedding ring using a 3D computer programme! As well as an interesting life, she has given us a unique and special gift and our rings are now all the more precious to us.”
The Cloud9 software is part of a complete design package — Chameleon — which includes the Falcon 3D mouse; uniquely available from A1 Technologies.

Engineers at the University of Southampton have designed and flown the world’s first ‘printed’ aircraft, which could revolutionise the economics of aircraft design.
The SULSA (Southampton University Laser Sintered Aircraft) plane is an unmanned air vehicle (UAV) whose entire structure has been printed, including wings, integral control surfaces and access hatches. It was printed on an EOS EOSINT P730 nylon laser sintering machine, which fabricates plastic or metal objects, building up the item layer by layer.
No fasteners were used and all equipment was attached using ‘snap fit’ techniques so that the entire aircraft can be put together without tools in minutes.
The electric-powered aircraft, with a 2-metres wingspan, has a top speed of nearly 100 miles per hour, but when in cruise mode is almost silent. The aircraft is also equipped with a miniature autopilot developed by Dr Matt Bennett, one of the members of the team.
Laser sintering allows the designer to create shapes and structures that would normally involve costly traditional manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from concept to first flight in days. Using conventional materials and manufacturing techniques, such as composites, this would normally take months. Furthermore, because no tooling is required for manufacture, radical changes to the shape and scale of the aircraft can be made with no extra cost.
This project has been led by Professors Andy Keane and Jim Scanlan from the University’s Computational Engineering and Design Research group.
Professor Scanlon says: “The flexibility of the laser sintering process allows the design team to re-visit historical techniques and ideas that would have been prohibitively expensive using conventional manufacturing. One of these ideas involves the use of a Geodetic structure. This type of structure was initially developed by Barnes Wallis and famously used on the Vickers Wellington bomber which first flew in 1936. This form of structure is very stiff and lightweight, but very complex. If it was manufactured conventionally it would require a large number of individually tailored parts that would have to be bonded or fastened at great expense.”
Professor Keane adds: “Another design benefit that laser sintering provides is the use of an elliptical wing planform. Aerodynamicists have, for decades, known that elliptical wings offer drag benefits. The Spitfire wing was recognised as an extremely efficient design but it was notoriously difficult and expensive to manufacture. Again laser sintering removes the manufacturing constraint associated with shape complexity and in the SULSA aircraft there is no cost penalty in using an elliptical shape.”
SULSA is part of the EPSRC-funded DECODE project, which is employing the use of leading edge manufacturing techniques, such as laser sintering, to demonstrate their use in the design of UAVs.
The University of Southampton has been at the forefront of UAV development since the early 1990s, when work began on the Autosub programme at its waterfront campus at the National Oceanography Centre, Southampton. A battery powered submarine travelled under sea ice in more than 300 voyages to map the North Sea, and assess herring stocks.
Now, the University is launching a groundbreaking course which enables students to take a Master's Degree in unmanned autonomous vehicle (UAV) design.
This is the first scheme of its kind and from September 2011, postgraduates can take part in a one-year programme covering the design, manufacture and operation of robotic vehicles. The degree will cover marine, land based and pilotless aircraft, typically used in environments that are deemed unsafe or uneconomic, such as exploration under sea ice, or monitoring gas emissions from volcanic eruptions. NASA expects UAVs to become 'standard tools' in fields such as agriculture, earth observation and climate monitoring.

Objet Ltd., the innovation leader in 3D printing for rapid prototyping and additive manufacturing, made news today by demonstrating a full-size folding stool able to support over 100 kg. Like the Objet 3D-printed skateboard, Objet engineers printed the stool in a single print job, using the new Objet ABS-like Digital Material (RGD5160-DM) – a new functionally advanced material which is jetted as a composite material on the Objet Connex multi-material 3D printer.
The folding stool, which sits 48 cm (19 inches) off the ground, has similar high dimensional stability, thermal resistance, and toughness as ABS-grade engineering plastics, enabling it to repeatedly sustain the weight of a person.
Commenting on the folding stool, Gilad Gans, Executive Vice President at Objet said; “The folding stool is a demonstration of the unique possibilities available using Objet’s multi-material 3D printers including the new Objet260 Connex. Our technology represents the most effective way of functionally testing complex design ideas. Whether skateboards or folding stools, the prototypes that come out of Objet Connex 3D printers look like the real thing and also perform like the real thing. Not only can this stool carry the weight of a person, but it was actually printed in the fold-up position in a single print job and then opened-up upon removal from the printer to be used.”
The Objet ABS-like Digital Material is a high-impact material (65-80J/m or 1.22-1.50 ft lb/in), with high-temperature-resistance (65°C or 149°F and after thermal post treatment 90°C or 194°F). The material is ideal for manufacturers and engineers looking to functionally simulate products made of ABS-grade engineering plastics, including snap-fit parts, durable and movable parts and products requiring drop-testing.
With the new ABS-like Digital Material, the number of Objet 3D printing materials is brought to a total of 65, including 51 composite materials (Digital Materials), for a wide range of rapid prototyping purposes, enabling realistic product visualization to advanced functional verification.

Shapeways, the online community and marketplace for personalized production using 3D printing, will be showcasing the latest 3D printed home décor items created by its talented community at the International Contemporary Furniture Fair (ICFF), North America’s premier showcase for contemporary design. Among the items will be an elegant dual purpose desk accessory, a combination pen holder and paper tray, designed by Shapeways community member Dominik Raskin. Chosen as the winner of Shapeways’ recent ICFF design competition, Raskin’s 3D printed design will be able to be seen by more than 24,000 interior designers, architects, retailers, designers, manufacturers, representatives, distributors, and developers who attend the show at the Jacob Javits Center in New York City (booth #1451) May 14-17.
“Our community truly amazes us with the incredibly cool things they make every day,” said Shapeways CEO Peter Weijmarshausen. “Our ICFF design contest not only inspired our community to get creative, but it also enabled one lucky winner to show their personal design to some of the most influential people in contemporary home design; hopefully, all the while having great fun!”
Dominik Raskin and His Winning Design
“My design concept came from the idea to create a minimal surface from which two functionalities could emerge, in this case the pen holder and paper tray,” said Shapeways community member and designer Dominik Raskin. “Adjustments were made to the initial shape to reduce material and costs without jeopardizing stability. First the mesh was tessellated and only the ribs maintained, then the base of the object was made smaller. This all added up to become a dynamic and novel shape.”
Raskin studied architecture in Brussels, Belgium. After working on a wide range of projects and gaining experience in several architecture offices, he moved to Mumbai, India to teach interior design and travel. His encounter with local students and designers such as Nuru Karim and Sameep Padora strengthened his instinct for poetry and natural forms in design.
After two years in India, Raskin pursued a new challenge to live and teach in Ho Chi Minh City, Vietnam. The penetration of contemporary Western thinking in Asia is something he deals with on a daily basis while working with students. They are eager to learn the Western way of thinking and designing, but Raskin also teaches them to value and not forget their cultural heritage.
Shapeways ICFF Contest Judges Weigh In
Shapeways asked journalists at some of most respected media outlets that cover design, 3D printing, and home décor to help judge the ICFF competition. More than 150 entries were received, and the judges were asked to choose their favorite designs, taking into consideration each item's aesthetics, as well as the innovative use of 3D printing technology.
Here’s what the judges had to say about Raskin’s winning pen and paper tray holder:
“What a great idea! It's multifunctional, beautiful, and quietly efficient,” said Suzanne LaBarre, senior editor at Co. Design, the design news site of FastCompany.com. “Plus it shows how 3D printing can be exploited to create exquisitely complex patterns that'd be next to impossible by any other method.”
“If you've ever seen dimensional illustrations exhibiting the effects of gravity and black holes deforming space-time, they look strikingly similar to the ornate symmetry exhibited here, transforming what is usually the most mundane of products, a paper tray, and injecting an element of motion and direction all across its surface,” said Gregory Han, managing editor of Apartment Therapy Unplggd, a site dedicated to the harmonious art of balancing technology with home decor. “There's also an entomological element which reminds of the strength and inherent beauty of insect wings, and the wave-like form (which at first glance I thought was a table) adds a playful temptation, inviting one to place something on its end, if only to see if the design counterbalances the weight. Overall, my favorite in form and function.”
“The beauty of Dominik's pen holder design is in the simplicity but most certainly in the dual purpose of such a piece,” said Josh Mings who writes at SolidSmack.com where he covers product development, design and related technology. “It's streamline and brings back the elegance of putting pencil to paper. The white material seems to spread off the paper and wrap around the instruments used to put thought back onto the paper.”

Shapeways (www.shapeways.com), the online community and marketplace for personalized production using 3D printing, is excited to announce that internationally renowned puzzle designer and long-time Shapeways community member Oskar van Deventer has achieved an unofficial world record with the creation of his 17x17x17 twisty puzzle 3D printed at Shapeways.com. The previous record was held by Leslie Lie from China for his 12x12x12 cube.
“When I heard about the world records being set for Rubik’s Cubes, like the 7x7x7, 9x9x9 and 11x11x11 created by Panagiotis Verdes from Greece, and Lie from China for his 12x12x12, I wanted to try to set a new record myself,” said Oskar van Deventer. “With sponsorship and prototyping help from my good friend Claus Wenicker, I began designing and testing a number of prototypes, and my third attempt was printed successfully with Shapeways.”
The puzzle, entitled “Over the Top,” took more than 60 hours over the course of the last year for van Deventer to design. The final puzzle design was 3D printed in 1,539 individual white strong and flexible plastic pieces by Shapeways. The pieces were then sorted and hand-dyed by van Deventer, a 10 hour process. Subsequent assembly added an additional five hours of labor. The result is a fully functioning 17x17x17 mechanical puzzle measuring 140 millimeters or 5.5 inch side to side. Puzzle enthusiasts need not have envy, 3D-printed do-it-yourself kits for a fully functioning puzzle are now available for sale for $2,000 at Shapeways.com: http://www.shapeways.com/model/64058/over_the_top___17x17x17
“At Shapeways, we enable anyone to bring their ideas and designs to life as real world objects,” said Shapeways CEO Peter Weijmarshausen. “With 3D printing, people are only limited by their imaginations. Shapeways inspires people to think outside the box, which fosters fresh ideas and innovation in product design. That’s the power of Shapeways.”
Van Deventer, an electrical engineer living in Leidschendam in the Netherlands, started designing his puzzles as hobby at the age of 12. Since 1988, he has sold puzzle designs to toy companies as a side job. Now, thanks to the invention of 3D printing technology and Shapeways.com, van Deventer is able to bring his puzzle designs immediately to a consumer market.
“Currently, when I have a new idea -- say, for a twisty puzzle -- a simple one might take me 5 hours from idea to market,” van Deventer said. “It’s a very quick way to get the design out of my system and into the world.”
Now, more than 30 years since he designed his first puzzle, van Deventer has certainly earned his reputation as one of the world's most prolific puzzle creators. Today, several of his innovations are sold at traditional toy stores and many more are available in his Shapeways shop “Oskar Puzzles”: http://www.shapeways.com/shops/oskarpuzzles. Most recently, one of Oskar's twisty puzzles, “Gift Cube,” was even used for a very original marriage proposal.

Autodesk, Inc. (NASDAQ: ADSK) announced today that KOR EcoLogic used Autodesk’s software solution for Digital Prototyping to design the first prototype car with a body created using a 3D printer. The KOR EcoLogic Urbee car gets up to 200 miles per gallon (MPG) and uses a hybrid electric/gasoline engine.
“From concept through rendering, Autodesk software helped us not only build an efficient and sustainable car, but also communicate our designs to a broader audience, including potential investors.”
The Autodesk Clean Tech Partner Program — which provides design and engineering software for emerging clean tech companies in North America and Europe — enabled KOR EcoLogic to design and test the Urbee using Autodesk tools, including Autodesk Inventor, Autodesk Showcase, and Autodesk Alias Design software.
“The Urbee was designed from the ground up to be as efficient as possible, and to run on renewable energy,” said Jim Kor, president and chief technology officer of KOR EcoLogic. “From concept through rendering, Autodesk software helped us not only build an efficient and sustainable car, but also communicate our designs to a broader audience, including potential investors.”
Using Autodesk partner Stratasys’ digital manufacturing service, Urbee is the first car to have its entire body 3D printed with an additive process.
Sustainability Central to Urbee’s Design
The KOR EcoLogic team began by developing a set of core principles and pinning them to their workshop wall. Among them, the Urbee was designed to use minimal energy and produce less pollution during its design, manufacturing, operation and recycling stages, while remaining affordable and visually appealing.
The Urbee can be charged through a standard home outlet, or through a home solar array, windmill or conventional energy source, running on as little as 1 cent of energy per mile travelled.
“Startup clean tech companies need technology enabling them to create professional, fully realized and tested designs, while benefiting from visually stunning imagery of their products,” said Robert “Buzz” Kross, senior vice president, Autodesk Manufacturing Industry Group. “KOR EcoLogic is a great example of the combined power of Digital Prototyping and sustainable design.”
The Urbee team used Autodesk Inventor software to design a 3D digital prototype of the car’s body and subject it to simulated road and wind conditions, test different body designs to minimize drag and reduce overall weight by eliminating excess parts. More than 80 percent of a product’s environmental impact can be determined during the design phase, making Inventor a critical component in establishing the Urbee’s high level of environmental responsibility. KOR EcoLogic used Autodesk Showcase 3D visualization software to create photorealistic renderings of the Urbee for marketing to potential investors, partners and the general public.
The Urbee was a contender for the 2010 Automotive X Prize, which challenges teams to design, build and race super-efficient, low-emission vehicles that can be manufactured for the mass market.
