EOS M 400

Metal 3D Printer

EOS M 400

Proven DMLS Quality for
Industrial Production

Increased productivity thanks to 1000-watt laser power

Modular platform with process and set-up station

Build volume of
400 x 400 x 400 mm

Highly Productive System

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.
