Product Details
- Shore 64D Semi-Rigid Hardness: Flex TPU 64D filament offers significantly higher rigidity, structural stability, and wear resistance than standard TPU, while retaining controlled flexibility for impact absorption. Perfect for parts needing toughness without excessive flex.
- Superior Mechanical Performance: TPU 64D 3d filament delivers high tensile strength, excellent abrasion resistance, and robust layer adhesion. Engineered to withstand repeated stress, bending, and impacts – ideal for functional gears, rollers, and mechanical components.
- Versatile Industrial & Engineering Applications: Designed for manufacturing aids, jigs, fixtures, protective covers, seals, vibration dampeners, and other components demanding a tough, wear-resistant, semi-rigid elastic material.
- Optimized for Reliable Printing: Formulated for smoother extrusion, reduced stringing, and clog resistance compared to many flexible filaments. Flex tpu 64d filament is compatible with most standard FDM/FFF printers (ensure proper flexible material setup).
- Biocompatibility Data: ISO 10993-10 (Sensitization), -5 (Cytotoxicity), & -23 (Irritation) test data available to support evaluation for skin-contact applications (User validation required).

Printing Siraya Tech TPU
Siraya Tech TPU in Black 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.
