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.

Print Recommendations
Abrasive Material
This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues.
Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
