ELEGOO Neptune 4 / Neptune 4 Pro - Brass 3D printer nozzle set

The ELEGOO Neptune 4 / Neptune 4 Pro Brass Nozzle Set is a ten-piece replacement kit for compatible FDM 3D printers. Each nozzle is made from brass, which conducts heat well and helps the filament melt consistently during extrusion. Four different diameters are included, so users can adjust the printer for different levels of detail and material throughput. The kit covers the sizes most often needed for routine maintenance and a range of projects. Keeping spares on hand cuts downtime when a nozzle wears out or becomes clogged.

The set is compact and easy to store as a maintenance reserve alongside the printer. Common printing materials such as PLA, ABS, PETG, and TPU are compatible with these nozzles, as long as the selected diameter and material match the printer's configuration. The 0.2 mm and 0.4 mm sizes suit detailed work, while the 0.6 mm and 0.8 mm sizes allow faster extrusion with wider layer lines. Replacing nozzles regularly helps maintain print quality once the existing tips start to wear. Having a range of diameters available makes it quick to reconfigure the printer when project requirements change.

• 2× 0.2 mm nozzles – for fine-detail prints with minimal layer height
• 4× 0.4 mm nozzles – standard diameter for everyday printing
• 2× 0.6 mm nozzles – intermediate size balancing detail and throughput
• 2× 0.8 mm nozzles – for faster extrusion and wider layer lines
• 50 g total pack weight – lightweight for convenient storage
