Product Details
- Superior Flexibility & Toughness: Siraya Tech's Flex TPU 85A filament excels in elastic recovery and impact resistance. With a Shore 85A hardness, it is significantly softer and more pliable than standard 95A TPU, making it the perfect choice for projects requiring a genuine rubber-like feel and long-term durability.
- ISO 10993 Tested: Our Flex TPU 85A has undergone testing according to ISO 10993-10, -5, and -23 protocols. These tests evaluate biological responses to materials, providing data on potential biocompatibility. This testing helps ensure peace of mind when printing for external-use wearables and devices.
- High Flow & High-Speed Printing: Engineered for efficiency, our high-flow formula allows for faster print speeds compared to traditional flexible filaments without compromising surface finish. For optimal results and to prevent buckling, we recommend using a direct-drive extruder.
- Long-Lasting Quality with Special Packaging: Our Flex TPU 3d printer filament is sealed in moisture-resistant aluminum resealable bags, preventing water absorption and ensuring up to 3 years of shelf life and consistent print quality.
- Versatile Industrial & Creative Applications: From custom high-visibility footwear components to ergonomic protective gear, this 1.75mm Green Flex TPU meets the demands of both industrial engineers and creative makers. And compatible with most 3D printers, it guarantees a smooth and reliable printing process, suitable for both beginners and experts.

Printing Siraya Tech TPU
Siraya Tech TPU in 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
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.
