All-metal integrated design for rapid assembly and disassembly: The nozzle and heat break feature an all-metal integrated design, enabling quick disassembly and easy replacement. Material upgrade, suitable for printing with various consumables: The throat is made of titanium alloy to reduce heat conduction. The nozzle is composed of copper alloy and hardened steel, supporting printing with a wide range of filaments. Compatible Filaments: PLA, ABS, PETG, TPU, PP, PC, PLA, PA, PET, etc. High flow, supporting 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. Data based on 0.4mm nozzle at 240°C. Integrated chromium-zirconium copper nozzle set: 1.75mm, 0.4mm + 0.6mm + 0.8mm, three-piece set (individually packaged), convenient and ready to use. Flat contact surface with tight-fitting joints to effectively prevent print head leakage. Smooth inner wall resists clogs. Inner hole roughness Ra less than 0.4 for smooth filament feeding. Fast and stable extrusion without clogging. Precision machining ensures high quality. Nozzle orifice is burr-free for stable printing and reduced clogging.
