Product Details
- 【High Heat Stability】- Polymaker HT-PLA-GF is engineered for functional prints that need to maintain their shape in high-temperature environments. After annealing, it provides enhanced heat resistance for demanding applications such as tool holders, brackets, fixtures, housings and functional prototypes.
- 【12% Glass Fiber Reinforced】- Reinforced with 12% glass fiber, HT-PLA-GF delivers higher stiffness and strength than standard HT-PLA for demanding functional parts. The glass fiber reinforcement also helps improve dimensional stability and gives printed parts a distinctive textured finish.
- 【Heat Resistant & Easy to Print】- Get high thermal performance without the printing complexity typically associated with ABS. HT-PLA-GF prints at 210–230°C with a 25–60°C heated bed and does not require an enclosed chamber, making it easier to print on a wide range of FDM 3D printers.
- 【High Speed up to 350mm/s】- Designed for printing speeds up to 350mm/s on compatible printers, HT-PLA-GF combines high-speed capability with low shrinkage and reliable dimensional stability. Suitable for jigs, fixtures, mechanical parts, tool organizers and repeatable functional prints.
- 【Hardened Nozzle Recommended】- Glass fiber is abrasive, a hardened steel or other wear-resistant nozzle is recommended. For higher heat resistance, anneal at 80–100°C for 20–30 minutes; 100°C for 30 minutes is recommended.

Printing Polymaker PLA-GF
Polymaker PLA-GF in Black is PLA filled with chopped glass fiber, and this listing is a 1kg spool. The fibers make parts stiffer and more dimensionally stable than plain PLA, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). The ranges below are for PLA-GF, which usually prints a little hotter than plain PLA. PLA-GF is best suited to stiff PLA parts with less warping, for indoor use. 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 Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our glass fiber 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.
