All materials for rigid SLS are industrial-grade technical polymers designed for high functional compliance. Endowed with fair aesthetic qualities, they may require additional machining to increase aesthetic qualities or change their coloring.
Sintered rubber evidences a smaller elastic range than is possible in industrial production and has an unmodifiable ShA hardness.
Blocks of plastic materials such as ABS, PA, POM and others specially formulated for machining by chip removal can be machined.
All PolyJet/Object plastic 3D printing materials are cartridge polymers designed for high aesthetic compliance and prototype appeal. They may have technical characteristics not in line with industrial products either in terms of stiffness or elasticity or ShA hardness.
