Polymaker™ HT-PLA-GF combines high-temperature stability with enhanced strength and durability. It withstands up to 150 °C without sagging or losing form. When annealed it can be perfect for functional parts that need to endure the heat.
Prints beautifully with standard PLA settings and supports speeds up to 350 mm/s. Just load and go, with no specialised tuning required.

Tougher. Stronger. Smarter. HT-PLA-GF is glass fibre-reinforced, delivering higher stiffness and durability for demanding applications. Note: This material is abrasive, so use a hardened steel or ruby nozzle for best results.

Need extra heat deflection? Anneal at 80–100 °C for 30 minutes (we recommend 100 °C) for an even higher HDT.
Hardened nozzle.
