Polymaker HT PLA-GF filament represents the evolution of traditional PLA, combining the ease of printing of this material with extraordinary thermal and mechanical resistance thanks to glass fiber reinforcement. Ideal for those looking for high-performance PLA without sacrificing the typical simplicity of PLA, HT PLA-GF allows for the creation of stiffer, more stable, and more durable parts with an impeccable finish.
Thanks to the adoption of advanced thermoplastic polymers and 20% glass fiber, this material offers heat resistance exceeding 90°C (HDT) and high rigidity, making it suitable for technical components, functional prototypes, support parts, display items, and lightweight industrial articles. The glass fiber also provides a matte and technical aesthetic effect that enhances the print.
The filament maintains the ease of use of PLA, with limited warping and no need for a heated chamber, while the vacuum packaging with desiccant ensures long storage and consistent performance.
