Additional Info
Aluminum (AlSi10Mg) is a strong, low weight material with good thermal properties. It’s printed by sintering aluminum powder together with a laser to produce metal parts that are equally as good as machined models. 3D-printed aluminum doesn’t look like traditional shiny milled aluminum. Instead, it has a matte gray finish with a slightly rougher and less defined surface. The subtle sparkle you’ll notice is caused by the presence of silicon in the alloy.

Aluminum is suitable for strong, light and precise metal parts. Applications range from spare parts to components of RC cars, gadgets, and even jewelry.
