Polymaker HT-PLA-GF Black Filament 1.75mm 1Kg

Polymaker HT-PLA-GF is a glass fiber reinforced high-temperature filament that combines the easy printability of PLA with the high stability of engineering compounds. Thanks to the glass fiber content, it offers exceptional rigidity, low shrinkage, and high dimensional stability. Parts remain dimensionally stable up to 130°C after annealing, making them suitable for applications that are subjected to significant mechanical and thermal loads. Despite the reinforcement, the material is reliable to print and can reach printing speeds of up to 350 mm/s. Particularly interesting is the good paintability, as is expected from PLA: surfaces can be easily primed, painted, or colored, making the filament ideal for model making as well as for cosplay, tabletop, or custom vehicle parts. HT-PLA-GF thus opens up possibilities that would otherwise only be achievable with technical materials such as ABS or ASA—but without their disadvantages such as limited color selection, extensive processing, or higher printing requirements. Due to the glass fiber reinforcement, the material acts abrasively on nozzles, which is why the use of a hardened nozzle is expressly recommended. During processing, there is little odor development, stronger than with PLA, but significantly more pleasant than ASA or ABS.

Properties:

• HT-PLA-GF offers high temperature resistance and remains stable up to 130°C after annealing.
• Glass fiber reinforcement ensures exceptional rigidity and stability.
• Very low shrinkage for dimensionally stable and precise parts.
• High layer adhesion and reliable printability.
• Low odor development, more pleasant than ASA or ABS.
• Paintability as expected from PLA, ideal for modeling, tabletop, and cosplay.
• High printing speed of up to 350 mm/s possible.
• Abrasive due to glass fiber – hardened nozzle recommended.

Recommended Print Settings:

• Printing temperature: 210–230 °C, recommended 230 °C
• Heated bed: 25–60 °C, recommended 50 °C
• Fan: 100%
• Printing speed: up to 350 mm/s

Annealing: Place finished part on a flat, heat-resistant surface and temper in an oven at 100 °C for about 30 minutes. Then let it slowly cool in the oven to avoid warping.
