EOS NickelAlloy C22 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 C22 parts with EOS M 290. 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 SkinCore. Both can be used separately for different parts or combined by using 40/80 µm SkinCore 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.
