EOS Demos Latest Advances in Laser-Sintered Orthopedic Products at AAOS

For proof positive that laser-sintering is changing the face of medical design and manufacturing, attendees of this year’s American Academy of Orthopedic Surgeons (AAOS) meeting can stop by the EOS booth. The world leader in laser-sintering systems is showcasing a working EOSINT M 280 direct metal laser-sintering (DMLS) system to demonstrate the extraordinary benefits the technology offers for orthopedic applications. The evidence includes a wide range of innovative medical products and prototypes used for instrumentation as well as spinal, joint, and cranial surgeries. The show is being held February 8-10 at the Moscone Center in San Francisco (California).

“An entire new world of orthopedic treatment and procedures has opened up,” says Martin Bullemer, EOS manager for medical business development. “Because our laser-sintering systems can cost-effectively manufacture any imaginable geometry, and any variation on it, they are changing the way we think about medical products.”

Laser sintering is an additive manufacturing process involving next-to-no tooling, molding or machining costs. As a result, devices can be economically mass-customized to conform to the requirements of individual doctors or patients. Orthopedic suppliers use DMLS and plastics laser sintering to create a diverse array of drill guides, clamps, implants, and surgical instruments.

EOS-related activities at the AAOS meeting include:

• EOS customers C&A Tool (booth 4017), Morris Technologies (booth 359), and Oxford Performance Materials (booth 2821) are exhibiting laser-sintered products and prototypes. C&A and Morris both focus on DMLS, while Oxford Performance Materials uses the EOSINT P 800 with high-performance polymers to manufacture customized medical implants.

• Highlights from WITHIN Technologies Ltd include their FEA/CAD optimization software that works with EOS’ plastic and metal laser-sintering systems to create strong, lightweight parts including innovative lattice structures.

• FHC is exhibiting its new line of patient-customized stereotactic fixtures for cranial targeting. The new fixtures are more accurate and comfortable for the patient than standard stereotactic frames and are suitable for a broad range of head types, and for targets not easily reached with a traditional frame. They also reduce operating room times for the procedure by as much as two hours.

“Many surgeons and medical designers are only just now becoming aware of the breadth of applications made possible by this manufacturing technology,” says Fred Haer, CEO of FHC. “The laser-sintered products on display at this meeting are at the forefront of a revolution in personalized patient care.”

EOS was founded in 1989 and is today the world-leading manufacturer of laser-sintering systems. Laser sintering is the key technology for e-Manufacturing, the fast, flexible and cost-effective production of products, patterns and tools. The technology manufactures parts for every phase of the product life cycle, directly from electronic data. Laser sintering accelerates product development and optimizes production processes.
