EOS M 300-4 – Digital Additive Manufacturing for the Industrial Production of High-Quality Metal Parts

Designed for industrial applications, the EOS M 300 series offers a high degree of flexibility and enables DMLS quality at up to 10x higher productivity. 


The new exposure module offers the flexibility to choose the number of lasers, their power as well as a fixed or variable focus


Up to four precise fiber lasers operate in a 300 x 300 mm square, each laser covering the entire build area


Exceptional beam and power stability provides consistent DMLS part quality across the entire build area including the full-field overlap


Flexibility to choose the degree of automation to best suit your needs for an optimized workflow – both as a stand-alone system and integrated in EOS Shared Modules
