Process Data Sheet
EOS Aluminium AlSi10Mg for EOS M 290 1kW | 80 μm
EOS M 290 1kW - 80 µm - TRL 3
Process Information Metal
1kW process with very high build rate to meet casting requirements. Low angle buildability and new supporting strategy enable low effort post processing.
Main Characteristics:
→ High productivity process with 1kW-Laser
→ Buildability up to 20° angle
→ Easier to remove support strategy
→ Reduction in post processing
→ Good surface roughness
