Enhanced durability and extended lifespan. The hotend features an all-metal tube, ensuring superior wear resistance and a longer lifespan. Optimized heating and cooling efficiency. The hotend employs a triple-rivet process that optimizes both heating and cooling efficiency. The heating and cooling components are crafted from chromium-copper alloy with a high heat transfer coefficient, which is three times higher than traditional brass. Additionally, the insulating component utilizes stainless steel with lower thermal conductivity. Minimal thermal deformation and high-temperature resistance. The hotend exhibits outstanding stability during operation and boasts high-temperature resistance, supporting temperatures of up to 300°C without compromising performance. Precise dimensional control for smooth extrusion. The hotend maintains a tight tolerance of 2μm, and this exceptional level of accuracy guarantees smooth extrusion. The overall extrusion experience is further enhanced thanks to the surface smoothness with a Ra value of 0.8.
