Extruder for Creality 3D printers — model 4001020076, compatible with Sermoon V2, CR-200B Pro, Ender-3 S1; colours: Black/Silver/White

Replacement extruder designed for use with Creality 3D printers. This extruder fits multiple Creality models including Sermoon V2, CR-200B Pro, Ender-3 S1, Sermoon V1/V1 Pro, Sermoon D3 and Ender-5 S1. Available in black, silver or white, the unit restores filament feeding capability and is intended for maintenance, repair or upgrade of the printer's extrusion system.

Advantages

The extruder provides consistent filament feeding and is engineered to match mechanical and mounting interfaces of the supported Creality models. Its construction supports reliable grip on standard filament diameters, reducing slippage and under-extrusion. Offering color options in black, silver and white allows visual matching with the printer housing or upgrades. Designed as a direct replacement, it streamlines installation and reduces downtime compared with more invasive repair methods.

Suitable for

• Replacing a worn, damaged or noisy extruder on compatible Creality printers
• Upgrading extrusion reliability to reduce print failures caused by filament slip
• Maintenance tasks where original extruder performance has degraded
• Spare-parts stocking for repair workshops or maker spaces using supported models

Key specifications

• Compatibility: Creality Sermoon V2, CR-200B Pro, Ender-3 S1, Sermoon V1/V1 Pro, Sermoon D3, Ender-5 S1
• Function: filament feeding/extrusion mechanism replacement
• Mounting: designed to match original Creality extruder mounting points for listed models
• Filament types: suitable for common thermoplastic filaments used on compatible printers (PLA, PETG, TPU when set up correctly)
• Colours: Black, Silver, White

How to use

Power down the printer and follow manufacturer guidance for safe component replacement. Remove the existing extruder assembly by disconnecting any wiring harnesses, heat-related parts and mounting screws as required for your model. Install the replacement extruder in the correct orientation, secure mounting screws, reconnect wiring and confirm that the filament path aligns with the hotend. After reassembly, perform a cold extrusion and calibration routine: load filament, advance through the filament load menu and verify smooth filament feed at low speed before running a test print.

Recommendations

Use the extruder with properly sized filament and appropriate print settings for the chosen material. Check gear engagement and tension after installation and periodically inspect for wear. When printing flexible filaments, adjust tension and retraction settings to prevent grinding. If the printer requires firmware or sensor recalibration after hardware replacement, follow Creality’s official procedures.
