EOS M 400

Additive Manufacturing System for the Industrial Production of High-Quality Large Metal Parts.

With a building volume of 400 x 400 x 400 mm, EOS M 400 allows the production of large metal parts on an industrial scale – directly from CAD data and with no need for tools.

Proven quality, high productivity

Increased productivity due to 1 kW laser

Reduced non-productive time due recoating from both sides

Reduced filter costs due to new recirculating filter system with automated cleaning function

Modular platform

EOS M 400 consists of a Process Station and a Setup Station. This modular approach facilitates the easy integration of future innovations.

Enhanced monitoring

Extensive monitoring features take quality management to a new level.

Sophisticated software

Job preparation and calculation is separated from the building process: the job file prepared at your
desk is transmitted via the network; the system focusses entirely on building parts.

Improved usability

EOS M 400 supports the production of complex metal parts. Nonetheless, the system is extremely

Quick and easy operation via touch screen.

Broad material portfolio

EOS offers an increasing number of metal materials for the EOS M 400 system. With the corresponding ParameterSets, the system produces parts with standardized part property profiles (PPPs).

The ParameterEditor enables you to modify parameters to meet your individual requirements.
