0.4mm Hardened Steel Nozzle for Elegoo Neptune 4 Plus / Max

## 0.4mm Hardened Steel Nozzle for Elegoo Neptune 4 Plus / Max

The **0.4mm Hardened Steel Nozzle for Elegoo Neptune 4 Plus Max** is a compatible aftermarket replacement designed for the Elegoo Neptune 4 Plus and Neptune 4 Max 3D printers. Combining hardened steel construction with a versatile 0.4mm opening, this nozzle provides an excellent balance between print detail, material flow and durability.

Hardened steel offers increased resistance to abrasive wear compared with conventional brass nozzles, making it a practical choice for users who regularly print with compatible demanding materials.

### Excellent Balance Between Detail and Performance

The 0.4mm nozzle diameter is a versatile choice for everyday FDM 3D printing.

Its relatively small opening allows for precise extrusion and good detail reproduction, making it particularly useful for models containing smaller features, detailed geometry and components requiring a clean surface finish.

The nozzle is suitable for a wide range of applications, including prototypes, functional components, decorative models and general-purpose printing.

### Hardened Steel Construction

Abrasive filaments can gradually wear down conventional brass nozzles, increasing the nozzle opening and affecting extrusion consistency.

Hardened steel provides improved resistance to this type of wear, helping maintain the nozzle opening during regular printing.

This makes the nozzle suitable for compatible abrasive materials, although users should always check the filament manufacturer’s recommended minimum nozzle diameter.

Some carbon fibre and glass fibre filaments require a larger nozzle opening to reduce the risk of blockages.

### Compatible Aftermarket Replacement

This nozzle is designed for use with the Elegoo Neptune 4 Plus and Neptune 4 Max.

It is a compatible aftermarket replacement and is not manufactured or supplied as an original Elegoo component.
