ELEGOO Assembled Extruder Kit for Neptune 4 Plus/4 Max

The ELEGOO Assembled Extruder Kit for Neptune 4 Plus/4 Max is a direct-drive extrusion replacement for FDM 3D printers. It is built specifically for the Neptune 4 Plus and Neptune 4 Max models as a drop-in replacement or upgrade for the stock extrusion system. The kit feeds 1.75 mm filament and supports PLA, PETG, ABS, TPU, flexible filament, and nylon. A dual-gear drive mechanism provides controlled filament feeding with increased torque. This design helps reduce slipping and extrusion interruptions during demanding prints. The unit is intended for users repairing or upgrading a compatible Neptune 4 printer.

The extruder's thermal system combines a high-temperature hotend with a dedicated heater element suited for demanding print jobs. An all-titanium alloy or copper-titanium bi-metallic throat manages heat creep during extended or high-speed printing. Cooling is handled by dual fans that maintain thermal stability across the hotend and extruder body. A PTFE tube guides filament through the extrusion path. The housing is finished in black. The assembly arrives ready for direct installation on a compatible Neptune 4 Plus or 4 Max printer.
