1. Introduction
This manual provides essential information for the safe and effective use of BEIBINGHE nozzles designed for Elegoo Neptune 4 Plus and Neptune 4 Max 3D printers. It covers installation, operation, maintenance, and specifications for various nozzle types and sizes. Please read this manual thoroughly before use.
2. Important Safety Information
Read all instructions before use. Failure to follow these instructions may result in damage to the product or personal injury.
- Warning: After using the product to print, the hotend nozzle will still be hot. Do not touch it with your hands!
- Keep away from children unless supervised by an adult.
- Do not use this product for purposes other than its intended use.
- Inspect the product before each use; do not use if damaged.
- Follow installation and operation guidelines to avoid injury.
3. Product Overview
BEIBINGHE offers a range of high-quality nozzles for Elegoo Neptune 4 Plus and Neptune 4 Max 3D printers, available in various materials and sizes to suit different printing needs.
Nozzle Types:
- Brass Nozzles: Standard, good thermal conductivity, suitable for common filaments like PLA, ABS.
- Plated Copper Nozzles: Feature high thermal conductivity (330W/m·k) and are uniformly heated, supporting high-speed printing up to 600mm/s. They also offer good corrosion resistance and extended service life due to advanced heat treatment technology.
- Hardened Steel Nozzles: Known for high hardness and wear resistance. The surface copper plating process enhances conductivity, anti-corrosion, and rust prevention, reducing filament adhesion and ensuring smoother extrusion.
4. Installation and Setup
- Ensure your 3D printer is powered off and cooled down before beginning installation.
- Carefully remove the old nozzle from the hot end.
- Screw the new BEIBINGHE nozzle onto the hot end. Do not overtighten initially.
- Heat the hot end to 200 degrees Celsius.
- Once heated, use a wrench to gently tighten the nozzle to prevent any leakage.
The nozzles are designed with a chamfered design to reduce resistance and ensure smooth feeding, preventing blockage or adhesion problems. They also feature a tight fit to prevent material leakage from the printing head.
5. Operation
These nozzles are compatible with 1.75mm consumables, including a wide range of FDM materials such as PLA, ABS, PETG, TPU, PC, PP, Nylon, and PEEK.
The advanced design ensures strong thermal conductivity and resistance to high temperatures (up to 500°C), contributing to stable and high-precision printing. The smooth inner wall (roughness Ra<0.4) reduces the likelihood of blockages and promotes uniform extrusion.
6. Maintenance
- Regularly inspect the nozzle for any signs of wear, damage, or clogging.
- Clean the nozzle periodically to remove any accumulated filament residue. This can be done using a brass brush or a needle while the hotend is heated.
- Ensure the nozzle is properly tightened after any maintenance to prevent material leakage.
- Store spare nozzles in a dry, clean environment to prevent corrosion or damage.
The corrosion resistance and wear-resistant properties of these nozzles contribute to a long service life, reducing the frequency of replacement.
7. Troubleshooting
- Filament Leakage: Ensure the nozzle is securely tightened to the hot end, especially after heating to 200°C during installation.
- Clogging/Blockage: This can be caused by filament residue or improper temperature settings. Try a cold pull or use a cleaning needle to clear the blockage. Ensure the filament is compatible with the nozzle and printer settings.
- Poor Print Quality (e.g., under-extrusion, stringing): Check if the nozzle is worn out and needs replacement. Verify that the printing temperature and retraction settings are appropriate for the filament being used.
- Nozzle Adhesion Problems: Hardened steel nozzles with copper plating are designed to reduce adhesion. If issues persist, ensure proper bed leveling and adhesion methods are used.

9. User Tips
- For optimal performance, match your nozzle material to your filament type. Brass is good for standard filaments, while hardened steel is recommended for abrasive materials like carbon fiber or glow-in-the-dark filaments.
- Always perform a PID tune after changing a nozzle or hotend components to ensure stable temperature control.
- Keep your filament dry. Moisture can cause printing issues that might be mistaken for nozzle problems.
- Consider using a silicone sock on your hotend to help maintain temperature stability and keep the hotend clean.
