TPU 92A-1, a thermoplastic polyurethane, is a fully-functional flexible and strong material. TPU 92A-1 is the only 3D printing material that combines the qualities of durable elasticity, high tear and abrasion resistance, high resistance to dynamic loading, snappy response and a good thermal resistance (-20°C to 80°C). This material is food-safe under certain conditions.

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.
