ELEGOO Neptune 4 Pro Extruder Kit – Description

The ELEGOO Neptune 4 Pro Extruder Kit is a fully assembled direct-drive extruder designed to restore or upgrade the extrusion system of the Neptune 4 Pro 3D printer. Built for precision, durability, and stable filament feeding, this extruder kit ensures consistent print quality across a wide range of materials.

The dual-gear direct-drive mechanism provides strong and accurate filament control, reducing slipping and improving extrusion reliability, especially when printing flexible or high-temperature filaments. With a maximum operating temperature of up to 300 °C, it supports materials such as PLA, PETG, TPU, ABS, and nylon.

The extruder features an efficient cooling system with dual 4015 fans, optimized airflow ducts, and a copper-titanium bi-metal heat break to reduce heat creep and minimize clogging. Supplied fully assembled, it allows for quick installation with minimal setup, making it an ideal replacement or maintenance part.

This extruder kit is specifically designed for compatibility with the ELEGOO Neptune 4 Pro and delivers smooth, stable, and reliable performance for both hobbyist and professional 3D printing applications.
