Designed specifically for the K1, K1 Max, and K1C. Packed with , it combines dual-gear mechanics, adaptive pressure handling, and ultra- coated components for smooth, reliable filament feeding. The DXCs helical gear system allows multiple gear teeth to engage the filament simultaneously. This grip dramatically reduces filament deformation and wear compared to traditional straight-cut designs, Helical gears reduce filament wear by 60%. With a synchronized dual-drive structure, the extruder doubles the contact area with the filament. This enhanced grip eliminates filament slippage and ensures constant, uninterrupted feeding, leading to cleaner layer lines and more detailed surfaces. Thanks to its adaptive pressure rocking arm, the extruder self-adjusts to accommodate filament of various hardness levels, such as TPU or standard PLA. This makes it ideal for multi-material workflows, reducing manual tuning while maintaining extrusion consistency. The open airflow design boosts internal cooling, mitigating risks of thermal creep and clogging. Combined with RNC-coated HV3300 gears rated for 3x the service life, the excels in both demanding environments and long-hour print jobs. Plug-and-Play, Installation is fast and straightforward-no firmware rooting is required for use with Crealitys . If using the optional onboard filament sensor, simply apply the included firmware update to unlock enhanced filament break detection and automatic recovery. Wide Filament Compatibility: The supports a broad spectrum of materials:PLA, ABS, PETG, ASA, PC, PA, TPU (95A-85A), PLA-, PET-, PA- - delivering flexible options for prototyping, engineering, and functional end-use parts.
