Polyamide powder filled with glass particles (PA-GF) has a much higher thermal resistance (up to 110°C) than polyamide, and is typically used in functional tests with high thermal loads. This material exhibits excellent stiffness, high density and tensile strength, combined with low specific weight. As a result, PA-GF is ideal for demanding conditions where stiffness, temperature performance or wear resistance is key.

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.
