Polymaker HT-PLA-GF – Glass fiber reinforced PLA for the highest demands

Polymaker HT-PLA-GF is a glass fiber reinforced PLA filament designed for superior heat resistance and mechanical strength. It combines the heat resistance of ABS with the easy printability of conventional PLA. This makes it perfect for functional parts, tools, and applications that must withstand higher temperatures.

Outstanding properties

• Heat resistant up to 130 °C after annealing

• High stiffness and improved mechanical performance

• Excellent dimensional accuracy due to extremely low shrinkage

• Easy processing with standard PLA printing settings

• Reinforcement with glass fibers for additional stability

• Ideal for engineering and industrial applications

Heat and stress resistant

With a heat deflection temperature (HDT) of up to 114.7 °C (0.45 MPa) and 84 °C (1.8 MPa) after annealing, this filament easily withstands high temperatures and mechanical stress – significantly beyond the limits of standard PLA.

Stability through glass fiber

The embedded glass fibers provide exceptional stiffness, high impact resistance, and minimal warping. With a modulus of elasticity of up to 4200 MPa, the material offers reliable mechanical properties in all print directions.

Precision without compromise

Thanks to an extremely low shrinkage of only 0.05% in the X, Y, and Z directions, precise components are produced – ideal for fixtures, assembly aids, or functional prototypes.

Easy handling

Polymaker HT-PLA-GF can be printed with standard PLA settings. A nozzle temperature of 210–230 °C and a heated print bed of 25–60 °C are recommended. Due to the abrasive glass fibers, a hardened nozzle is advisable.
