Product information

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.
