Centauri Carbon Hardened Steel Nozzle – 0,4 mm

Highly durable hardened steel nozzle designed for 3D printers Elegoo Centauri and Elegoo Centauri Carbon. Thanks to a combination of optimized geometry for high flow rates and hard material, it is ideal for fast printing and long-term use with abrasive materials.

Why choose a hardened steel nozzle for Centauri Carbon

• Maximum wear resistance – hardened steel is significantly harder than standard brass, so it does not deform or widen the orifice even during long-term printing with carbon and other filled filaments.
• Constant diameter 0,4 mm – permanently precise output hole ensures consistent line width, quality surface, and repeatable part dimensions even after hundreds of hours of printing.
• Designed for Centauri / Centauri Carbon – full compatibility with the original Elegoo Centauri and Centauri Carbon hotend; the nozzle meets the dimensional requirements of these printers and is easy to replace.
• Suitable for high-speed printing – the nozzle is designed for high flow rates, as used by Centauri Carbon during fast printing, and helps maintain stable extrusion with denser and technical materials.

Usage and recommended materials

This nozzle is intended especially for:

• abrasive filaments: PLA/ PETG / nylon with carbon or glass fibers, filled composites
• technical plastics: nylon, PC blends, ASA/ABS with fillers
• standard materials (PLA, PETG, TPU, ABS) – if you want one durable nozzle "for everything" without frequent replacement

For purely decorative printing only with unfilled PLA, a brass nozzle can be used, but for any abrasive filament, hardened steel is almost a necessity, otherwise the brass will wear out within a few hours to tens of hours of printing.

Compatibility

• 3D printers: Elegoo Centauri, Elegoo Centauri Carbon (and other machines with the same hotend / thread as the Centauri series)
• System: FDM/FFF
• Hotend type: original and compatible hotends for Centauri/Centauri Carbon using this type of nozzle

Key benefits for users

• Less frequent nozzle replacement due to high hardness and resistance to abrasion
• Better dimensional accuracy of parts even after long periods of use
• Reliable operation at high speeds for which the Centauri Carbon is designed
• Universal diameter 0,4 mm – the most common choice for a balance between speed and detail

Technical specifications

Tips for use

• When installing the nozzle for the first time, always tighten it while heated (according to the hotend manufacturer's recommendation) to achieve proper tightening and tightness.
• For abrasive materials, regularly check the condition of the nozzle, but with hardened steel, wear will be significantly slower than with brass.
• For maximum print quality, use a suitable profile for Centauri / Centauri Carbon in your preferred slicer and adjust the temperature and speed to the specific filament.

This nozzle is an ideal choice for Elegoo Centauri/Centauri Carbon users who want to fully utilize the possibilities of fast printing while simultaneously printing technical and abrasive materials without fear of rapid nozzle destruction.
