Polymaker expands PLA portfolio with two heat-resistant high-performance filaments

Filament manufacturer Polymaker has introduced two new PLA-based materials for industrial 3D printing. With HT-PLA and HT-PLA-GF, the company is specifically addressing applications that were previously reserved for more conventional engineering plastics such as ABS. Both materials are compatible with standard FDM printers and are primarily intended for use in functional prototyping and applications involving thermal stress.

HT-PLA offers an unusually high heat resistance for PLA of over 130 °C directly after printing. In contrast to other heat-resistant PLA variants, no additional post-treatment by tempering is required, according to the manufacturer. The material is characterized by a low tendency to warp and can be processed over a wide temperature range. This makes it suitable for industrial production processes as well as for precise components with high surface quality.

Building on HT-PLA, Polymaker has developed HT-PLA-GF, a glass fiber-reinforced variant. This is intended to achieve a mechanical strength that is higher than that of ABS. The increased rigidity and tensile strength allows it to be used in applications subject to mechanical stress. Although HT-PLA-GF is intended for heat treatment, it exhibits high dimensional stability with minimal shrinkage even in an untempered state, according to the manufacturer. This allows components to be manufactured with tight dimensional tolerances.

Both materials are available in different colors. HT-PLA is available in ten standard colors and four gradient shades, while HT-PLA-GF is initially available in nine colors specially selected for tools and technical components.
