Precise Compatibility for Neptune Series

This original extruder kit is tailored for ELEGOO Neptune 3 and Neptune 4 series, including Plus, Max, 4, and 4 Pro models. Choose the version matching your printer’s interface—old universal or new Type-C—to ensure perfect fit and operation.

Old Model Extruder—Reliable Basics

Designed for earlier Neptune models, the classic extruder features a traditional wiring interface and red control motherboard.

Ideal for standard temperature printing with PLA and PETG materials, it supports daily, ordinary model printing requirements.

Stable compatibility with older motherboards
Capable of standard temperature printing
Limited support for flexible and high-speed printing

New Type-C Interface Extruder—Enhanced Performance

The upgraded extruder uses a Type-C interface for stable signal transmission and simplified wiring.

Equipped with a black control motherboard optimized for faster response and better heat dissipation, it supports printing up to 300℃.

Perfect for advanced engineering materials like ABS, PC, polyamide, and carbon fiber-filled filaments.

Type-C communication interface for stable data
Supports high-speed, high-precision printing
Maintains high-temperature output up to 300℃
Optimized airflow and heat dissipation design
