Alumide is a blend of aluminum powder and polyamide powder, which allows metallic-looking, non-porous components to be machined easily and is resistant to high temperatures (130°C). Typical applications include parts for wind tunnel testing in the automotive industry, small production runs, jig manufacturing, education and illustrative models with a metallic appearance.

How Does Laser Sintering Work?
Laser Sintering is a laser-based technology that uses solid powder materials, typically plastics. A computer-controlled laser beam selectively binds together particles in the powder bed, by raising the powder temperature above the glass transition point after which adjacent particles flow together. As the powder is self-supporting, no support structures are necessary.
