A1mini nozzle quick replacement, precise extrusion. The magnetic block on the A1mini hot end heating component allows for quick and accurate nozzle fixation to the installation position, enabling easy and convenient disassembly and installation. Before replacement, ensure the hot end has cooled down and avoid touching the heating block at the bottom of the hot end to prevent injury. Smaller nozzle size provides higher print precision. Color: Black & Silver. Material: Metal. Size: 0.8mm. Kind reminder: Do not use the 0.2mm nozzle to print consumables containing carbon fiber, glass fiber, metal, or other inorganic particles, as it may cause clogging. PLA and PETG filaments have been tested multiple times and can be printed using a 0.4mm hardened steel nozzle, which is less prone to clogging and delivers good print quality. It is recommended to use a 0.6mm hardened steel nozzle when printing with filaments containing carbon or glass fibers to minimize the risk of clogging and wear.
