ELEGOO Neptune 4 and Neptune 4 Pro - Pre-assembled Hotend Kit

The ELEGOO Pre-Assembled Hotend Kit for Neptune 4 and Neptune 4 Pro is a replacement assembly designed for specific ELEGOO FDM 3D printers. It features a 0.4 mm nozzle and is built to process 1.75 mm filament. This accessory allows users to swap out a complete hotend unit instead of replacing individual components. The integrated design ensures proper alignment between the heating element, thermistor, and extrusion path. It is intended for Neptune 4 and Neptune 4 Pro owners who need to restore reliable print performance.

Operating at temperatures up to 300 °C, the assembly accommodates high-temperature materials like ABS and Nylon, as well as PLA, PETG, and TPU. A widened aluminium heat sink is incorporated into the build to manage thermal loads and support efficient heat dissipation. The pre-assembled format provides stable temperature control and consistent extrusion during print runs. Including all necessary components in a single unit reduces maintenance downtime. This kit serves as a direct replacement part to keep a compatible printer operational.

• Pack of 1 pre-assembled hotend provides a complete replacement unit
• Silver and black colour scheme matches standard printer hardware aesthetics
• 23.8 g total weight minimises added load on the extruder carriage
• PTFE tube included for reliable filament feeding
• Brand compatibility with ELEGOO ensures correct fitment within the manufacturer's 3D printer ecosystem
