Nylon Settings for Elegoo Neptune 3 Plus

Temperature Settings

Start with the nozzle at 260°C and the bed at 80°C. If you see poor layer adhesion, increase the nozzle temperature by 5°C increments. If you experience stringing, decrease the nozzle temperature by 5°C. For the first layer, you can increase the bed temperature by 5°C for better adhesion, then let it drop back to 80°C for subsequent layers.

The Nylon filament has a recommended nozzle temperature range of 240-280°C and a bed temperature range of 70-90°C. The Elegoo Neptune 3 Plus supports nozzle temperatures up to 300°C and bed temperatures up to 100°C, which fully covers the recommended range for this filament.

Speed & Quality

For the Elegoo Neptune 3 Plus, a print speed of 30-50 mm/s works well with Nylon. The first layer should be printed at 15-25 mm/s for solid bed adhesion. Outer walls at 70-80% of the main speed produce cleaner surface finishes.

For quality-critical prints like miniatures or display pieces, reduce the speed to 30 mm/s and use a 0.12-0.16mm layer height. For draft or rapid prototyping, you can push the speed to 50 mm/s with a 0.24-0.28mm layer height. The standard 0.2mm layer height at 40 mm/s provides the best balance of speed and quality for most prints.

Bed Adhesion

Nylon is notoriously difficult for bed adhesion. Use a PEI sheet with glue stick, or a Garolite (G10) sheet for the best results. A brim is essential for most nylon prints. Some users also find blue painter's tape with glue stick works well.

Common Issues with Nylon on Elegoo Neptune 3 Plus

Here are the most common problems you may encounter when printing Nylon on the Elegoo Neptune 3 Plus, along with proven solutions:

• Warping: Use an enclosure, brim, high bed temp, and ensure a draft-free environment
• Bubbles or popping during printing: Filament is wet -- dry for 12-20 hours at 80°C
• Poor layer adhesion: Increase nozzle temperature, reduce fan, and ensure filament is thoroughly dry
• Stringing: Almost always caused by wet filament; dry it thoroughly before printing

Tips for Best Results

Follow these expert tips to get the best possible prints with Nylon on your Elegoo Neptune 3 Plus:

• Drying is absolutely critical -- even new sealed spools benefit from 12+ hours of drying at 80°C
• Print from a dry box or active filament dryer; nylon re-absorbs moisture during the print
• Garolite (G10) sheets provide the best bed adhesion for nylon
• After printing, you can boil nylon parts to moisture-condition them -- this triples impact strength
• Start with PA12 if you are new to nylon; it is much easier to print than PA6

Support Settings

For prints requiring supports with Nylon, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.
