EOS Aluminium AlSi10Mg for EOS M 290 | 60 µm
EOS M 290 - 60 µm - TRL 3
Process Information Metal
Higher productivity process can be used where mechanical requirements are less demanding but
where cost-efficiency is needed. The 60 μm EOS M 290 process has high resolution of fine features and buildabilty of thin walls.
Heat treatment can be used to affect mechanical properties.
Main Characteristics:
→ Increased productivity of aluminum parts with EOS M 290
→ Good mechanical properties
→ Good buildability of challenging geometries
