All-metal integrated design for rapid assembly and disassembly: The nozzle and heat break feature an all-metal integrated construction, enabling quick disassembly and convenient replacement. Material upgrade for compatibility with a variety of filaments: The heat break is made of titanium alloy to reduce heat conduction. The nozzle is composed of copper alloy and hardened steel, supporting printing with multiple filament types. Compatible filaments: PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, PET-CF. High flow rate for high-speed printing: Enlarged nozzle chamber achieves a maximum flow rate of up to 30 mm³/s, supporting high-speed printing at 600 mm/s. Tested at 0.4 mm nozzle size and 240°C. Flat contact surface and tight joint fit: Effectively prevents print head leakage. Smooth inner wall minimizes clogging. Inner hole surface roughness (Ra) less than 0.4 µm ensures smooth filament feeding. Extrusion is fast and stable without clogging. Precision-machined orifice with no burrs ensures stable printing and reduced risk of blockage.
