EOS StainlessSteel 316L-4441 for EOS M 290 | 40/80µm
EOS M 290 - 40/80 µm - TRL 3
Process Information Metal
This process product is optimized for flexible and fast production of EOS StainlessSteel 316L-4441 parts with the EOS M 290 system. The parameter set has three different layer thickness options that can all be utilized within the same build: 40 µm, 80 µm and 40/80 µm Skin. 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 long established 40 µm parameter set. With the 40/80 µm Skin parameter set, the total build time can be reduced with the same surface quality. The parameter sets are assigned to different sections in the same build job depending on the requirements.
Main characteristics:
→ Parameter set for fast and cost efficient production of EOS StainlessSteel 316L parts in small series or serial production
→ With 80 µm parameter 100 % increase in productivity compared to the 40 µm FlexLine parameter set
→ Faster production without compromising the part qualit
