High flow rate supports high-speed printing,The nozzle cavity is enlarged, up to 32mm³/s, supporting 60mm/s high-speed printing. The all-copper radiator has good heat dissipation performance, even heat dissipation and smooth extrusion. 360° surround ceramic heating coil with built-in copper-plated heating ring to increase heating rate. The nozzle is made of hardened steel SKD11, which is quenched and hardened + surface DLC nano-treatment, and can be heated up to 450°C, making it more wear-resistant and extending its service life.
