Product Description:
Elevate your 3D printing performance with the Neptune 4 Extruder Upgrade Kit—engineered to transform your printer into a precision workhorse. Designed for ELEGOO Neptune 4/Pro/Plus/Max models, this kit replaces the stock extruder with industrial-grade components to eliminate common issues like filament slipping, gear wear, and extrusion inconsistencies.

Key Features for Superior Prints:
Nanocoated Mold Steel Gears: The helical gear teeth are treated with a nano-coating to resist corrosion and abrasion, ensuring smooth filament feeding even with tough materials like Nylon or PC. CNC machining guarantees tight tolerances for minimal backlash and precise layer adhesion.
One-Piece Shaft Design: Eliminates assembly errors with a pre-integrated shaft, reducing eccentric rotation and improving filament delivery uniformity—critical for high-speed printing up to 500mm/s. Dual Ball Bearings: Upgraded bearings reduce friction and noise while enhancing gear alignment, extending the extruder's lifespan to handle thousands of hours of printing.
Hassle-Free Installation: Includes all mounting hardware and a step-by-step guide. No need to modify firmware or calibrate settings—simply swap the old extruder and start printing within minutes.
Perfect for Every Maker:
Whether you're printing functional prototypes, detailed models, or flexible parts, this upgrade ensures consistent results across materials. The 105°C heat resistance expands your creative possibilities, while the low-volatility design minimizes maintenance downtime.
