ELEGOO Assembled Extruder Hotend Kit for Neptune 4 Plus and Neptune 4 Max

The ELEGOO Assembled Extruder Hotend Kit for the Neptune 4 Plus and Neptune 4 Max is a replacement printhead assembly designed for the corresponding ELEGOO Neptune 3D printers. It combines the heating element, heat sink, and filament path into a single pre-assembled unit to simplify maintenance. Users install this component to restore normal extrusion on compatible machines. The assembly is made for a specific printer family, so it fits directly without any modifications. Replacing a worn printhead with this unit resolves common extrusion failures.

The component feeds standard filament sizes through a dedicated nozzle. A ceramic heater delivers fast thermal output to the hotend block, keeping the melt conditions stable. This allows the assembly to handle common thermoplastics used in desktop 3D printing without manual tuning of the heating element. A widened aluminium heat sink manages heat dissipation during long print runs. The assembled unit weighs 150 g and comes as one pre-built replacement part for straightforward installation.

• 1.75 mm filament compatibility: matches the standard diameter used by most FDM printers
• 0.4 mm nozzle diameter: standard orifice size for detailed and general-purpose prints
• 60 W ceramic heater: fast heating and stable thermal performance
• 300 °C maximum hotend temperature: supports high-temperature filaments
• PTFE tube filament path: provides a smooth feeding channel for the filament
• Compatible with PLA, ABS, PETG, ASA, TPU, and Nylon: covers the standard range of desktop 3D printing materials
