Material overview
TPU is a laser-sintered elastomer that combines rubber-like flexibility with abrasion and tear resistance. Because SLS needs no supports, it prints complex lattices, bellows and living hinges that can’t be molded economically — with tunable stiffness through geometry. Ideal for gaskets, seals, grips, footwear midsoles, shock absorbers and flexible enclosures. Standard surface is matte black; dyeing available.
Highlights
- Shore ~88A — rubber-like flex
- High elongation ~250%
- Abrasion & tear resistant
- Lattices & living hinges support-free
