Description
Polymaker HT-PLA-GF is a specialized PLA composite infused with 8% – 10% chopped glass fibers. This reinforcement significantly increases the material's stiffness and dimensional stability compared to standard PLA.
The "HT" stands for High Temperature; unlike standard PLA, which softens at 60°C, this filament is designed to undergo an annealing process after printing. Once annealed, the Heat Deflection Temperature (HDT) can reach nearly 100°C, making it suitable for under-the-hood automotive clips, industrial jigs, and high-load mechanical housings that would typically require nylon.
Features
Built for serious performance
Polymaker™ HT-PLA-GF combines high-temperature stability with enhanced strength and durability. 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.

Safety Precautions
-
Always print in a well-ventilated area.
-
Avoid breathing the fumes while printing.
-
Do not touch the nozzle, heated bed, or printed object right after printing — let it cool down first before handling.
-
Keep the printer and filament away from children and pets.
-
Unplug the printer when not in use.
-
Store the filament in a cool, dry place to avoid moisture.
-
Wear gloves and a mask when sanding, cutting, or handling printed parts.
-
Keep away from open flames — most filaments are flammable.
PLA
- Safe and low-odor filament, but still print with good ventilation.
- Avoid overheating to prevent smoke or odor.
- Allow the print to cool down before removing from the bed.
