The CFS Upgrade Kit Extruder is the official replacement extruder for the K1 Series CFS Upgrade kit. Please note: This extruder is only compatible with K1 series machines that have the multi-colour upgrade kit installed as well as the Creality K2 SE 3D Printer.
The CFS Upgrade Kit Extruder is only compatible with the Creality unicorn nozzle. The wear-resistant dual gears ensure durability against repeated feeding and retraction, as well as the abrasive nature of fibre-reinforced filaments.
The built-in “zero-distance” filament break detection mechanism in the CFS Upgrade Kit Extruder accurately identifies feeding interruptions and promptly alerts the user; the shorter detection distance reduces waste of filaments
The integrated filament cutting blade enables precise colour changing operations; Easy to install and manufactured from wear-resistant materials for extended service life and simplified maintenance.
