The CHT clone hardened steel nozzle can increase the flow rate and smooth extrusion of high-quality filament without clogging. The hardened steel material is resistant to high temperatures and wear, and the minimum printing life is approximately 50 grams of carbon fiber filament. With three holes, the filament flow rate is twice that of standard nozzles, allowing for high-speed printing. Replace Puyong's V6 nozzle with a CHT nozzle to achieve a performance similar to a volcanic nozzle. Made of high-quality hardened steel, the insert is made of copper, offering improved wear resistance and faster heat conduction. High precision design ensures a smooth and burr-free inner surface, and the flat end face of the nozzle enhances contact with the heating elements, which can effectively prevent filament leakage from the heating end and reduce the risk of clogging. This CHT high-speed nozzle is compatible with all popular V5, V6 1.75mm FDM 3D printer models, such as FOR 13, S, MegaX, Pro, and is not suitable for Vyper 3D printers.
