SAHVAIM Printheads for 3D printer Hotend for A1 Mini/A1 Print Head Upgrade High-Temperature 0.4MM Hardened Steel Nozzle Hot End Kit Extruder Replacement with 1PC 0.4 mm Nozzle

• 【New upgraded design】Compared with other versions on the market, our print head has been upgraded and modified, and the hot end nozzle can be replaced. Customers no longer need to replace the entire hot end of the print head due to nozzle blockage or damage. Customers can directly replace nozzles with different diameters for printing, which is convenient and cost-effective, bringing customers a better printing experience. 【Quick replacement】The magnetic block on the A1mini hot end heating component can quickly and accurately fix the nozzle to the installation position, making disassembly and installation of the nozzle easy and convenient* Before replacement, please ensure that the hot end has cooled down and avoid touching the heating block at the bottom of the hot end to prevent burns. 【Superior Durability】The hot end kit is designed with high-quality hardened steel material, which has high hardness, high temperature wear resistance, and durability. The inner wall of the nozzle is smooth and free of burrs. The hot end of the kit defaults to using a 0.4mm nozzle, balancing printing speed and quality. It is the standard nozzle for contemporary 3D printers. 【Wide Compatibility】The hot end set is compatible with 1.75mm filaments, including PLA, ABS, PETG, TPU, PC, PP, nylon, and PEEK. If you want to print a higher quality model, you can choose a 0.2mm caliber, and the smaller the size, the higher the precision of the model. Alternatively, if you want a faster printing speed, you can choose a nozzle with a diameter of 0.6 or 0.8. The larger the nozzle, the more consumables it can squeeze out per second, resulting in a faster printing speed.
