EOS Announces New Modular M 400 DMLS Machine

EOS is presenting the new EOS M 400 at Euromold 2013. The new modular and extendable system gears additive manufacturing up for application in industrial production environments. The system enables the manufacture of larger components with an increased level of automation. In addition, the EOS M 400 delivers improved quality assurance and is easier to use, thereby answering key requirements of our series production customers. The commercialization of the basic model begins in the spring of 2014, with the global distribution planned from the summer.

“EOS is pursuing a platform-based strategy for the metal technology and is able to support its customers from the research and development phase, through to the series production. The EOS M 400 represents the key to the industrial series utilization of Additive Manufacturing. If the EOSINT M 270 and EOSINT M 280 models have set the technical benchmarks, then the EOS M 400 takes these a step further. The new system supports users not only in the context of its qualification for production, but also in actual manufacturing applications. “We won't be drawing the line at a single solution. We will be expanding the platform with successive performance modules”, says Adrian Keppler, Managing Director at EOS.

The EOS M 400 is based on a modular concept and is initially available with both set-up, and process stations. Within a year, an automated unpacking station will also be on offer. With this extension of the system, an exchangeable frame, including components and residual powder, is moved, following the build process, from the process station to the unpacking station. Here, the job will quickly be cleaned of all loose and excess powder by way of a clean-up program comprising rotation and vibration. The modular concept makes it possible to incorporate the unpacking station retroactively to expand on the set-up and process stations. Users thereby gain a future oriented e-manufacturing solution designed for application-specific, modular extension.

A further key innovation of the EOS M 400 is the volume of the building chamber, which measures 400x400x400 mm so that larger components can now be produced. The first extension to the basic model, with its corresponding processes, will initially be offered with the EOS Aluminum AlSi10Mg and EOS NickelAlloy IN718 materials and is thereby particularly suited for use in the automobile and aerospace sectors. Processes for further materials are still in the development phase, including both tool steel and titanium.

In the EOS M 400 the laser has a performance of up to 1,000 watts. It allows the use of new materials that require more powerful lasers. A new user interface with touchscreen, developed out of talks with many customers, further simplifies the system usability. The complete handling has been optimized. Additionally, the filter from the air filtration system is automatically cleaned and has a significantly longer use-life. EOS has also further optimized both the monitoring and reporting functions, enabling the user to enjoy advancements in quality control. All of these innovations are aimed at meeting the requirements of series production and represent a further important step in making this a reality.

From 2015, EOS is planning to offer in addition to the EOS M 400 the EOS M 400-4 which will come with four lasers. While the single-laser version opens the way for the development of new applications, the focus of the multi-mode variant lies in achieving productivity increases of qualified production processes that have been already achieved for the EOSINT M 280.
