EOS M 400-4

Ultra-fast, ultra-productive: Our flagship four-laser machine.

With four 400-watt lasers and a 400 x 400 x 400 mm build volume, the EOS M 400-4 is the ultimate productivity platform for industrial applications.

Key Features

Four Versatile Lasers

With four precise 400-watt lasers, the EOS M 400-4 delivers up to 4x productivity while ensuring the highest DMLS part quality.

Automated Calibration

Precision laser calibration is vital for repeatable part quality. The EOS M 400-4 automates multi-laser calibration for consistent results. 

Build Big

With a 400 x 400 x 400 mm build volume, the EOS M 400-4 is engineered for serial manufacturing of large metal parts.

Longer Service Life

A circulating air filtering system with automatic cleaning means fewer filter changes and less production downtime.
