Printing SainSmart TPU

SainSmart TPU in Rainbow runs on the TPU profile below, and this listing is a 1kg spool. TPU is best suited to flexible, rubber-like parts such as phone cases, gaskets, and vibration dampers. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.

Ranges checked against Bambu Lab and Prusa data. Heat resistance is the heat deflection temperature (HDT). Read our TPU filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.

Nozzle Compatibility

Flexible filament is not abrasive, so brass and hardened steel both work. Size matters more: the higher pressure in a small nozzle makes soft filament buckle in the extruder.
