Markforged Smooth TPU 95A Black / White - 800CC, 1.4kgMarkforged Smooth TPU 95A (Thermoplastic Polyurethane) is a rubber like material that gives you the ability to create flexible, shock absorbing parts. It is a highly flexible and soft material that can stretch many times its original shape before it fails. TPU is one of the few elastic materials that can be printed with an FFF 3D printer. Because it is a soft, flexible filament, TPU is known in the industry as a very challenging material to print.
