Printing SainSmart TPU

SainSmart TPU in Glow Green 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

This listing includes glow-in-the-dark filament. The phosphorescent pigment that makes it glow is hard and wears brass nozzles quickly, even though the filament looks like ordinary plastic. Use hardened steel or another wear resistant nozzle, starting about 5 to 10°C hotter than with brass.

Based on Bambu Lab, Polymaker and eSUN guidance. More in our nozzle types guide.
