EOS Aluminium AlSi10Mg for EOS M 400-4 | 80 µm
EOS M 400-4 - 80 µm - TRL 5
Process Information Metal
This process parameter is developed specifically for fast and cost-efficient production of aluminum
parts with similar mechanical properties as conventionally produced casting parts. EOS T6 heat treatment is recommended for parts where higher elongation properties are required.
Main Characteristics:
→ Highest productivity of aluminum parts on the EOS M 400-4: Up to 261 cm3/h build rate
→ Excellent buildability for challenging parts
→ Two different parameter set options available for surface exposure
