EOS FeNi36 for EOS M 290 | 40 µm & 80 µm
EOS M 290 - 80 µm - TRL 3
Process Information Metal
This process product is optimized for flexible and fast production of EOS FeNi36 parts with the EOS M 290 system. The parameter set has two different layer thickness options that can all be utilized within the same build: 40 µm and 80 µm. The 40 µm parameter set is ideal for parts needing great detail resolution and more dense structure. The 80 µm parameter set offers a build rate that is more than double that of the 40 µm parameter set. The parameter sets are assigned to different sections in the same build job depending on the requirements.
