Polymaker HT-PLA-GF 1.75mm White 1kg Glass Fiber Reinforced High-Temperature PLA Filament

Polymaker HT-PLA-GF is a high-performance PLA filament reinforced with glass fibers, designed for applications requiring enhanced stiffness, heat resistance, and dimensional stability. This 1.75mm diameter filament offers excellent printability while delivering mechanical properties superior to standard PLA. The matte finish and recycled cardboard spool reflect Polymaker's commitment to sustainability.

Advantages

Glass fiber reinforcement significantly increases stiffness and heat resistance compared to standard PLA. After annealing, parts can withstand temperatures up to 130°C. The material is easy to print with a wide temperature range and minimal warping. The matte surface finish hides layer lines and provides a professional appearance.

Suitable for

• Functional prototypes and end-use parts requiring high stiffness
• Jigs, fixtures, and tooling for manufacturing
• Automotive and mechanical components exposed to moderate heat
• Enclosures and structural parts
