EOS
M 400

Proven DMLS Quality for Industrial Production

System Data Sheet
Key Features

Exceptional Quality at High Volume

Ideal for serial manufacturing of large metal parts, the EOS M 400 delivers repeatable excellence.

Highly Productive

1000-watt laser power increases productivity with higher build rates and thicker layers. Ideal for serial manufacturing of large metal parts.

Easy to Use

Coating both sides with powder material reduces production downtime. A circulating air filtering system with automatic cleaning means fewer filter changes and longer service life. 

Broad Portfolio of Materials

A comprehensive collection of materials is available, from light metals to stainless steel, tool steels and super alloys.
