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

Polymaker HT-PLA-GF is a glass fiber reinforced high-temperature filament that combines the ease of printing with PLA with the high stability of engineering compounds. Thanks to the glass fiber content, it offers exceptional rigidity, low shrinkage, and high dimensional stability. Components remain form-stable up to 130°C after annealing, making them suitable for applications that are heavily mechanically and thermally stressed. Despite the reinforcement, the material can be reliably printed and achieves print speeds of up to 350 mm/s. Particularly interesting is the good paintability as expected from PLA: surfaces can be easily primed, painted, or decorated, making the filament ideal for model making, cosplay, tabletop, or custom vehicle parts. This opens up possibilities with HT-PLA-GF that would otherwise be achievable only with technical materials like ABS or ASA – but without their disadvantages such as limited color selection, complex processing, or higher printing requirements. Due to the glass fiber reinforcement, the material is abrasive on nozzles, so the use of a hardened nozzle is expressly recommended. During processing, there is a low odor development, stronger than PLA, but much more pleasant than ASA or ABS.

Properties:

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

Recommended Print Settings:

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

Annealing: Place the finished part on a flat, heat-resistant surface and anneal in the oven at approximately 100 °C for 30 minutes. Then slowly cool down in the oven to avoid warping.
