SUNLU PC Filament

SUNLU PC filament delivers exceptional toughness and high impact strength (up to 35 kJ/m²) combined with reliable heat resistance up to 94 °C, making it ideal for demanding functional and industrial applications. Designed for stable high-temperature printing at 260–280 °C, it provides strong layer adhesion, minimal warping, and excellent dimensional stability when used in an enclosed chamber. With its ability to withstand drops, heat, and prolonged mechanical stress, SUNLU PC is a reliable choice for durable tools, outdoor items, and high-performance components.

With a heat deflection temperature of up to 94 °C, the material retains its shape without deformation at high temperatures, effectively preventing issues like warping and softening caused by heat. It offers a reliable material solution for demanding applications with strict temperature requirements and is an ideal choice for industrial high-temperature environments, precision equipment manufacturing, and similar fields.

SUNLU's high-toughness PC material exhibits excellent impact strength with a notched impact strength of 35 kJ/m² and boasts impressive resistance to drops and impacts, allowing it to withstand heavy daily use.

Optimized for high-temperature materials, it melts stably at temperatures above 260 °C, delivering superior rigidity and heat resistance. A controlled print speed of ≤190 mm/s ensures perfect extrusion and layer adhesion – without clogging, warping, or cracking. Ideal for industrial high-temperature parts and robust, functional models.
