EOS StainlessSteel PH1 for EOS M 290 | 40/80 µm

EOS M 290 - 40/80 µm - TRL 3

Process Information Metal

This process product is optimized for flexible and fast production of PH1 parts with EOS M 290 and M 400-4 systems. The parameter  set has three different layer thickness options that can all be utilized within the same build: 40µm, 80 µm and 40/80 µm Skin. For high productivity needs a 80 µm parameter set is included with a build rate more than double the long established 40 µm parameter set. Both can be used separately for different parts or combined by using 40/80 µm Skin with faster 80 µm for the core of the part and higher quality 40 µm building for the surface of the part with defined thickness. Sectionioning parts in vertical direction for different parameters is also possible.
