Nozzle for 3D printer Creality Volcano 0.4 mm, brass, for 1.75 mm filament

Brass replacement nozzle Creality Volcano with a 0.4 mm orifice designed for 1.75 mm filament. Compatible with Volcano-style hotends, this nozzle provides a standard 0.4 mm nozzle diameter suitable for general-purpose extrusion. It is intended for printing medium-detail parts, prototypes and functional components using common filaments such as PLA and PETG within the hotend's temperature limits.

Advantages

This brass nozzle offers good thermal conductivity for stable melt flow and consistent extrusion at typical printing temperatures. The 0.4 mm orifice balances print speed and detail, enabling reliable layer deposition for a wide range of models. Its geometry matches Volcano-style hotends, ensuring straightforward mechanical fit and replacement without requiring hotend modification when used with compatible 1.75 mm setups.

Suitable for

• General-purpose FDM 3D printing with 1.75 mm filament
• Prototyping and functional part production with PLA and PETG
• Medium-detail models where a balance of speed and surface quality is required
• Replacement or spare nozzle for Volcano-style hotends

Key specifications

• Nozzle material: brass
• Orifice diameter: 0.4 mm
• Filament diameter compatibility: 1.75 mm
• Compatible hotend type: Volcano-style
• Recommended filament types: PLA, PETG and similar thermoplastics within hotend temperature limits

How to use

Allow the hotend to reach printing temperature before removing the existing nozzle to avoid filament residue hardening. Use an appropriate wrench to unscrew the old nozzle, taking care not to damage the heater block or thermistor. Screw the new brass Volcano 0.4 mm nozzle in by hand until seated, then tighten with a wrench while the hotend is at the recommended temperature for brass to ensure proper sealing. After installation, recalibrate nozzle offset and run a test print to confirm extrusion quality and dimensional accuracy.

Usage recommendations

To prolong nozzle life and maintain print quality, avoid printing highly abrasive filaments with bare brass; consider a hardened or plated nozzle for frequent abrasive material use. Regularly clean the nozzle and perform cold pulls or use appropriate cleaning tools to remove residue. Match print temperatures and retraction settings to the filament type, and recheck bed leveling after nozzle replacement.
