ELEGOO Neptune 4 MAX Extruder Kit is a fully assembled direct-drive extruder designed as an original replacement or upgrade for the Neptune 4 MAX 3D printer. Built for high-flow, stable, and precise filament feeding, this extruder ensures consistent print quality even during long, large-format prints.

The dual-gear direct-drive system provides strong and accurate filament control, reducing slipping and improving extrusion reliability across a wide range of materials. With high-temperature capability, the extruder supports common and advanced filaments such as PLA, PETG, TPU, ABS, and nylon.

An optimized cooling design with efficient fans and a bi-metal heat break helps minimize heat creep and clogging, ensuring smooth and uninterrupted printing. Supplied fully assembled, the extruder kit allows quick installation with minimal calibration, making it an ideal maintenance or replacement component for maintaining peak performance of the Neptune 4 MAX.
