EOS Aluminium AlSi10Mg for EOS M 290 | 30 µm
EOS M 290 - 30 µm - TRL 9
Process Information Metal
High performance process with smooth and shiny surfaces. Process is developed to have high density
with smooth vertical surfaces. T6 heat treatment enables excellent elongation with moderate strength and reduced anisotropy.
Main Characteristics:
→ Good mechanical properties and low amount of defects.
→ Shiny and smooth surfaces on vertical areas.
→ Mechanical properties can be modified with heat treatment.
