Product Details

  • Stiff Yet Tough: The "Non-Brittle" Solution - Unlike standard glass-fiber filaments (like PLA-GF) that are rigid but prone to shattering, Fibreheart combines a tough TPU 64D base with high-strength glass fibers. This "Stiff yet Tough" balance resists brittle fracture, allowing parts to withstand heavy impacts and drops while retaining high structural rigidity.
  • Superior Vibration Damping - The inherent damping properties of the TPU base effectively absorb and dissipate mechanical vibrations. This makes Fibreheart the ideal material for printing drone frames, motor mounts, and protective housings where reducing jitter, noise, and mechanical stress is critical.
  • Reinforced Structural Strength - Precision-cut glass fibers significantly boost mechanical rigidity and load-bearing capacity compared to standard TPU. It delivers the reliable structural integrity needed for functional manufacturing jigs, fixtures, and tools that must hold their precise shape under stress.
  • Exceptional Wear & Chemical Resistance - Built for harsh environments, the fiber reinforcement provides a surface hardness that resists abrasion and wear. Additionally, Fibreheart offers excellent chemical resistance against common oils and solvents, making it perfect for long-lasting automotive and industrial components.
  • Ultra Low Warp & Easy to Print - Say goodbye to the frustration of lifting corners and failed prints. The glass fiber reinforcement acts as a stabilizing skeleton within the TPU matrix, drastically reducing thermal shrinkage and warping. This unique formulation allows for excellent bed adhesion and dimensional stability, making it easy to print large, complex functional parts even on standard desktop FDM printers.

Printing Siraya Tech TPU-GF

Siraya Tech TPU-GF in Black is TPU filled with chopped glass fiber, and this listing is a 1kg spool. The fibers make parts stiffer and more dimensionally stable than plain TPU, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). Few makers publish separate TPU-GF settings, so the ranges below are for plain TPU; expect to print toward the top of them. 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.

Nozzle temp
210-240°C

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

Glass fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.
