Neptune 4 Extruder Gear Upgrade Kit - Nanocoated Mold Steel Dual Gear Extruder for Elegoo Neptune 4/Pro/Plus/Max, One-Piece Shaft Integrated Gear Assembly

$26.20

  • Unmatched Durability & Precision: Crafted with nanocoated mold steel helical gears and CNC-machined one-piece shaft, ensuring superior concentricity, reduced gear wear, and consistent filament feeding for high-detail prints.
  • 5.2:1 High Torque Extrusion: Dual gear design delivers 30% stronger pushing force than stock extruders, eliminating slipping/under-extrusion—ideal for PLA, ABS, TPU, PETG, and abrasive materials like carbon fiber.
  • Wide Compatibility: Direct replacement for ELEGOO Neptune 4, 4 Pro, 4 Plus, and 4 Max 3D printers. No firmware modifications required; pre-assembled for plug-and-play installation.
  • High-Temp Stability: Withstands temperatures up to 105°C, enabling reliable printing with high-melt materials. Low volatility design ensures minimal warping and consistent flow during extended prints.
  • Upgraded Bearing System: Driven gear features dual ball bearings (vs. original needle rollers) for reduced clearance, smoother transmission, and extended lifespan (HRC 62-65 hardness rating).

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.
