Features: Upgrades for K1C printer with this advanced nozzle featuring ceramic heating block for rapid temperature uniformity and five interchangeable nozzles (0.2 0.8mm) to optimize precisions printing across materials. The ceramic heating block ensures stable thermal performances under prolonged high temperature operations, while machined brass nozzles provide wear resistant durability for consistent extrusion in detailed or fast speed printing projects. for professional makers, prototyping workshops, and printing enthusiasts requiring nozzle configurations for multiple materials projects like PLAs, PETG, or composite filaments. for creating intricate miniatures, functional prototypes, or large scale architectural models where layer resolution and extrusion consistency determine print quality. Engineered with precisions milled components and toolless nozzle swapping, this all metal hotend upgrades delivers industrial reliability for continuous printing workflows without clogs or thermal drift. Specifications: Materials: metal Size:(optional) Nozzle: 0.2mm Nozzle: 0.4mm Nozzle: 0.6mm Nozzle: 1mm Nozzle: 0.8mm Package Includes: 1PC Heating Block note: Please allow 0-1cm error due to manual measurement. make sure you not mind before bid.
