Features: Engineered with low thermal conductivity (0.2 0.3W/m·K), this synthetic stone heatbreak enhances thermal insulation by 25%. Compared to standard models, preventing premature filaments heating for lab mini 3D printers. From high temperature resistant composite materials (800°C continuous/up to 1100°C), it features optimized 0.3 0.4W/m·K thermal efficiency and less than 1% thermal degradation at 500°C through rigorous TGA testing. Essential for 3D printing enthusiasts, industrial designers, and engineering professionals requiring precisions extrusion control during extended printing. Maintains consistent nozzle temperatures during 3D printing projects, from rapid prototyping to educational workshop applications. The synthetic stone heatbreak’s advanced thermal management minimizes heat creep, ensuring stable extrusion flows for complex geometries and high detail prints.
