Product Details
- EXTRA-FAST HIGH-FLOW PRINTING: Stop wrestling with notoriously slow flexible filaments. Our upgraded TPU 95A HF (High Flow) is engineered for extreme speeds, hitting a Max Flow Rate of 15 mm³/s. It melts and extrudes smoothly, allowing you to slash print times and achieve flawless layer adhesion without frustrating clogs or stringing.
- PREMIUM MATTE FINISH & RUGGED TOUGHNESS: Ditch the cheap, shiny plastic glare. This Matte Black filament delivers a sleek, stealthy, and professional aesthetic that expertly hides layer lines. Striking the perfect balance between rubber-like flex and unbreakable strength, it’s the ultimate choice for drone/RC car parts, heavy-duty gaskets, and premium footwear.
- ISO-TESTED SKIN-SAFE FOR WEARABLES: Building custom orthotics, cosplay armor, smartwatch bands, or external medical device prototypes? Our TPU has been rigorously tested to ISO 10993 (-10, -5, and -23) biocompatibility protocols, giving you absolute peace of mind when creating 3D prints designed for prolonged skin contact.
- NO MORE WET, BUBBLING FILAMENT: TPU notoriously absorbs humidity, leading to popping nozzles and ruined prints. We solved this by sealing every spool in a premium, heavy-duty aluminum resealable bag. This lets you print as soon as you receive the filament without drying and keeps your filament bone-dry between prints.
- CLOG-FREE PRECISION & COMPATIBILITY: Manufactured with strict +/- 0.03mm diameter accuracy to ensure unwavering consistency from the first millimeter to the last. Universally compatible with most 1.75mm FDM 3D printers (Note: For the absolute best flexible printing experience, a direct drive extruder is highly recommended).

Printing Siraya Tech TPU
Siraya Tech TPU in Matte 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.
