TPU is a flexible, Rubber-like material used for printing 3d parts for industrial and consumer applications. TPU filament is the go-to filament, when additive manufacturing parts that require rubber and plastic qualities. TPU’s elasticity makes it ideal for prototyping large, complex part with stretch, abrasion and tear resistance. Commonly printed items include gasket rings, tubes, seals, grips, etc. The most commonly used TPU 3d printing process is FDM.
