COCOON PET-Cactus(HTGF) is a glass fiber reinforced, heat-resistant consumable, offering an "enhanced, heat-resistant" solution for 3D printed PET materials. It boasts a heat deflection temperature of up to 182°C without the need for annealing or waiting. This consumable also features high heat resistance, high strength, high stiffness, and high creep resistance, along with good fluidity and stable extrusion performance. The printed products have a matte and frosted texture, with high heat resistance and mechanical strength. They are waterproof, have excellent chemical resistance, and combine outstanding mechanical properties with good dimensional stability, making them widely applicable in functional components, load-bearing structures, and auxiliary tooling fixtures for 3D printing scenarios involving long-term loads.
