## Summary description

Hardened steel 0.4 mm nozzle compatible with Elegoo Neptune 4 Plus and Neptune 4 Max 3D printers, designed for 1.75 mm filament. Provides wear resistance for abrasive materials and stable extrusion through a standard 0.4 mm orifice. Suitable for general-purpose printing, extended use with composite/filled filaments, and replacing worn factory nozzles to restore print quality.

## Long description

Hardened steel 0.4 mm nozzle designed for use with Elegoo Neptune 4 Plus and Elegoo Neptune 4 Max 3D printers and for 1.75 mm filament. The nozzle combines a standard 0.4 mm orifice for balanced detail and flow with the durability of hardened steel to resist wear from abrasive and composite filaments. It is intended as a replacement for worn factory nozzles or as an upgrade when printing abrasive materials, helping to maintain consistent extrusion and dimensional stability over extended print runs.
Advantages
This hardened steel nozzle offers increased wear resistance compared with standard brass nozzles, extending service life when using carbon-, metal- or glass-filled filaments. The 0.4 mm bore preserves general-purpose printing characteristics—reasonable detail, reliable flow, and compatibility with common slicing profiles. The nozzle’s material and finish reduce degradation caused by abrasive particles while maintaining thermal transfer suitable for typical printing temperatures used with composite and standard filaments.
Suitable for
General-purpose 3D printing with 1.75 mm filament
Printing composite filaments containing carbon, glass or metal particles
Replacing a worn or damaged factory nozzle on Elegoo Neptune 4 Plus / Neptune 4 Max
Extended production runs where nozzle wear is a concern
Key specifications
Nozzle orifice diameter: 0.4 mm
Filament diameter compatibility: 1.75 mm
Material: hardened steel
Intended mounting: compatible with Elegoo Neptune 4 Plus and Neptune 4 Max hotend geometry
Typical use: abrasive and standard filaments, composite-filled materials
How to use
Power off and cool the hotend before removing the existing nozzle. Use an appropriate wrench to hold the heater block and a nozzle tool to unscrew the old nozzle, then thread the hardened steel nozzle by hand to avoid cross-threading and tighten to the manufacturer’s recommended torque. Heat the hotend to a normal printing temperature for the filament in use and perform a filament purge to confirm smooth extrusion and correct flow. Check bed leveling and first-layer settings after installation to ensure proper adhesion and dimensional accuracy.
Usage recommendations
For best results with composite or abrasive filaments, use recommended print temperatures and slower print speeds compared with non-abrasive materials to maintain consistent extrusion; inspect the nozzle periodically for buildup and clean with appropriate tools when cooled. Avoid overtightening during installation to prevent damage to the hotend threads.
