3DXFLEX TPU (85A) Flexible 3D Filament

3DXFLEX™ TPU (85A) Thermoplastic Polyurethane 3D Printer Filament

3DXFLEX™ TPU (85A) elastomer is an engineering-grade material that we chose based on its balance of printability, flexibility, chemical resistance, and toughness. 3DXFLEX™ TPU has a hardness of 85A, allowing you to make very tough, impact resistant, flexible prints. We recommend direct-drive extruders, but experienced users can be successful with Bowden-type drives as well.
