    EOS M 400-4
    The Ultra-Fast Four-Laser System

    for the Additive Manufacturing of High-Quality Metal Parts


Up to 4x more productivity 


Four precise 400-watt fiber lasers


Build volume of
400 x 400 x 400 mm


With a build volume of 400 x 400 x 400 mm and four lasers, the EOS M 400-4 platform achieves up to four-times higher productivity, making it perfect for industrial applications. Four precise 400-watt fiber lasers work over an area of 250 x 250 mm each, with 50 mm overlap.


With its intuitive user interface, flexible software tools and diverse accessories, the system meets every usage requirement of an industrial production environment. Highly automated procedures and processes guarantee ease of operation. 


A broad portfolio of materials is available, from light metals to stainless steel, tool steels and super alloys. Any process from the EOS M 290 can be transferred to the EOS M 400-4 to achieve equivalent part properties.
