Extruder Creality 3D 4001020075 for Ender-3 V3 Plus K1 K1 Max K1C

The Creality 3D 4001020075 extruder is a replacement extruder compatible with Creality Ender-3 V3 Plus, K1, K1 Max and K1C 3D printers. Available in black, grey and white finishes, this extruder is a direct-fit spare part designed to maintain filament feeding accuracy and consistent printing performance for supported Creality devices.

Advantages

This extruder offers stable filament drive and straightforward installation to restore or upgrade the filament-feed system of supported Creality models. Its compatibility with multiple printers in the Ender and K series reduces the need to source different parts for each model. The choice of three colours helps match the printer aesthetic or replace an original part with a visually similar component.

Suitable for

• Repairing a malfunctioning extruder on Ender-3 V3 Plus
• Replacing worn or damaged extruder components on K1, K1 Max and K1C printers
• Keeping spare parts on hand for continuous printing workflows
• Standard filament feeding tasks with compatible Creality printers

Key specifications

• Type: Extruder designed for direct replacement on specified Creality models
• Compatible printer models: Ender-3 V3 Plus, K1, K1 Max, K1C
• Available colours: Black, Grey, White
• Function: Filament feeding / drive mechanism for FDM 3D printing

How to use

Power off and unplug the printer before beginning replacement. Remove the existing extruder according to the printer manufacturer’s service instructions, taking care to note cable and filament routing. Install the Creality 3D 4001020075 extruder in place of the original, secure mounting screws, reconnect any wiring and ensure proper alignment of the filament path. After installation, load filament and perform a filament feed test, then recalibrate extrusion settings if necessary through the printer’s control interface or slicing software.

Recommendations

Use this extruder with the recommended filament types and diameters for your printer model. Inspect filament drive gears and bearings periodically for wear, and keep the extruder area free of dust and debris. If you experience under- or over-extrusion after installation, check gear tension, filament path alignment and extrusion multiplier settings before assuming a hardware fault.
