The EOS M 400 is designed for industrial production applications, as the increased volume of the build chamber (400 x 400 x 400 mm) allows the manufacture of larger components or more smaller parts. In addition, the level of automation has been raised, making it suitable for with serial production. In the EOS M 400, the laser has an output of up to 1,000 watts, allowing the use of materials that require more power. 

The basic model will start to become available in the spring of 2014, with global distribution planned from the summer.

“We are pursuing a platform-based strategy for metal AM technology and are able to support customers from the research and development phase through to series production,” said Adrian Keppler, MD at EOS. "EOS M 400 represents the key to industrial production, as it takes EOSINT M 270 and EOSINT M 280 technical benchmarks a step further. 

"The new system supports users not only in the context of its productivity, but also in actual manufacturing applications, as we will be expanding the platform with successive performance modules."

The company says that automated unpacking will be available for the EOS M 400 within a year. 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, loose and excess powder will quickly be cleaned away by programmable rotation and vibration. 

The modular concept makes it possible to incorporate the unpacking station retroactively to expand on the set-up and process stations. 

The first extension to the basic model will initially be available with EOS aluminium AlSi10Mg and EOS nickelalloy IN718 materials and is therefore particularly suitable for use in the automobile and aerospace sectors. Processes for further materials are still in the development phase, including both tool steel and titanium.

From 2015, EOS is planning to offer, besides the EOS M 400, the EOS M 400-4, which will have four lasers to help increase productivity.
