ASSEMBLED EXTRUDER KIT FOR NEPTUNE 4 PRO

Restore peak performance to your 3D printer with the official ELEGOO Assembled Extruder Kit for Neptune 4 Pro. Purpose-built as a direct-fit replacement, this comprehensive pre-assembled unit contains everything needed to get your Neptune 4 Pro back up and running with optimal precision, reliable extrusion, and outstanding layer adhesion.

High-Torque Dual-Gear Direct Drive

Featuring an advanced dual-gear direct drive system with an optimized 5.2:1 reduction ratio, this extruder provides powerful grip and consistent filament flow. The wear-resistant stainless steel gear teeth firmly feed filament without slipping or grinding, while a lightweight profile ensures minimal gantry load for faster, cleaner printing.

300°C High-Temperature Hotend & Bi-Metal Throat Pipe

Expand your printing capabilities with an extended hotend capable of reaching temperatures up to 300°C. Combined with a copper-titanium bi-metal throat pipe, the assembly delivers superior heat dissipation and prevents heat creep, drastically reducing the risk of nozzle clogs. Easily handle standard filaments like PLA and PETG, or venture into technical materials including ABS, TPU, and Nylon.

Enhanced Dual-Fan Cooling

Equipped with dual 4015 ball-bearing cooling fans positioned on both sides, this extruder assembly directs focused, high-volume airflow straight to the hotend and active print layers. This rapid cooling power minimizes stringing and warping, guaranteeing sharp details even during high-speed printing.
