  • Hyper Speed: The SainSmart GT-3 TPU filament is designed to balance high printing speeds of up to 500mm/s with printing quality. 5 times faster than regular TPU filament.
  • UV Protection: The filament resists damage from UV rays and aging factors, which extends its lifespan and maintains its performance. This makes it ideal for various applications, particularly those exposed to outdoor or harsh conditions.
  • Elasticity & Toughness: With a hardness rating of 95A, this filament offers high elasticity and exceptional toughness. It is ideal for creating intricate and bendable prints that require movement, such as phone cases, flexible toys, prosthetics, and other parts that need to stretch or deform.
  • Compatibility: This filament, with its 1.75mm diameter, will work on a variety of 3D printers like Creality K1, K1 Max, Ender-5 S1, Anycubic Kobra 2, ELEGOO Neptune 4, Bambu 3D Printers, Ankermake M5 & AnkerMake M5C, Flashforge Adventurer 5M & Adventurer 5M Pro, Prusas, Monoprice, FLSUN V400, Artillery, Qidi MAX3, SCRIB3D, MYNT3D, etc.
  • Recommend Printing Setting: Nozzle Temp: 220-240°C, bed Temp: 30-50°C, printing speed:300mm/s, dimensional accuracy +/- 0.04 mm.
  • Noted: Flexible TPU and other flexible filaments are not suitable to be put into the Bambu Lab AMS system (Multi-color printing).

1. To achieve the best printing effect, try to dry the printing (55℃/ >4H). It is recommended to use it with the SainSmart dryer box when printing.

2. It is recommended to use a direct dual-gear extruder. Generally, GT-3 TPU is difficult to print with a bowden extruder. Try printing at a slower speed when using bowden extruder. A speed of 20 mm/s or lower is recommended.

3. After long printing times, impurities may remain in the nozzles. It is recommended to use cleaning lines in conjunction with the printer. Replace new nozzles and throats if necessary.


What's Different Between Flexible PLA and Flexible TPU?

Aspect Flexible PLA Flexible TPU
Material Composition Modified polylactic acid (PLA) with additives Thermoplastic elastomer with polyurethane chains
Environmental Impact Relatively more biodegradable Synthetic material, potential biodegradability varies
Performance Characteristics Slightly lower rebound resilience and durability Outstanding elastic recovery, fatigue resistance
Application Fields Moderate flexibility, not extreme fatigue resistance High flexibility, excellent stretching, fatigue resistance
Examples of Applications Light stress parts, decorations, etc. Shoe soles, seals, elastic components, etc.
