Product Details
- Flexible and soft: Specially formulated plastic with increased flexibility and rigid structure. Recommended for printing objects that are more affected than normal ones. 1.75mm diameter, 87A hardness, 1.12 density (g/cm³).
- TPU (Thermoplastic Polyurethane) is a subclass of thermoplastics that prints strong parts that are also flexible.
- Short Distance Feed Needed: The flexible material must be fed on short distance feed, and there is no gap between the wire feed roller and the extruder, otherwise the flexible material will curl and get stuck between the two, resulting in poor feeding.
- Premium TPU filament: TPU (thermoplastic polyurethane) is a subclass of thermoplastics that prints strong parts that are also flexible. It has high transparency, high mechanical strength and good properties.
- Impact resistance and wide applicability: Great performance in waterproof, cold and UV resistance, good for industrial production, medical applications, industrial art, personal DIY, etc.

Printing SainSmart TPU
SainSmart TPU in Natural 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.
Based on Bambu Lab and Prusa guidance. More in our nozzle types guide.
