SainSmart Small Spool 1.75 mm TPU Flexible 3D Filament 250 g, Dimensional Accuracy +/- 0.05 mm, Shore 95A, Galaxy Blue

Product Details

• SainSmart thermoplastic polyurethane (TPU) filament is known for its high quality and allows you to create flexible and instantly stable printed objects with an even and smooth surface
• Compatibility: It is compatible with most fused deposition modelling (FDM) printers on the market that use 1.75 mm filament, including SainSmart x Creality, Prusa i21, Monoprice MakerSelect & Qidi and other RepRap printers
• Thermoplastic polyurethane (TPU) is a special type of thermoplastic elastomer (TPE). Compared to generic TPE, TPU is stiffer and more durable. It also has good abrasion resistance, excellent bed adhesion and low wrapping, making it a perfect material for different applications
• Thermoplastic polyurethane (TPU) filament is very versatile and is therefore commonly used in 21D printing. You can use it to make your own mobile phone cases, phone stands, toys and so on

Printing SainSmart TPU

SainSmart TPU in Blue runs on the TPU profile below, and this listing is a 0.25kg 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.
