ABS Settings for Elegoo Neptune 4

Temperature Settings

Start with the nozzle at 245°C and the bed at 103°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 103°C for subsequent layers.

The ABS filament has a recommended nozzle temperature range of 230-260°C and a bed temperature range of 95-110°C. The Elegoo Neptune 4 supports nozzle temperatures up to 300°C and bed temperatures up to 110°C, which fully covers the recommended range for this filament.

Speed & Quality

The Elegoo Neptune 4 supports high-speed printing at up to 500 mm/s. For ABS, we recommend 60-200 mm/s for general printing. Start with the lower end for quality-critical prints and increase for draft prints. Always print the first layer at 25-50% of your normal speed for better adhesion.

For quality-critical prints like miniatures or display pieces, reduce the speed to 60 mm/s and use a 0.12-0.16mm layer height. For draft or rapid prototyping, you can push the speed to 200 mm/s with a 0.24-0.28mm layer height. The standard 0.2mm layer height at 130 mm/s provides the best balance of speed and quality for most prints.

Bed Adhesion

ABS requires high bed temperatures (95-110°C). Use PEI sheets or apply ABS slurry (ABS scraps dissolved in acetone) for excellent adhesion. A brim is strongly recommended for medium and large parts. Kapton tape is another classic option.

Common Issues with ABS on Elegoo Neptune 4

Here are the most common problems you may encounter when printing ABS on the Elegoo Neptune 4, along with proven solutions:

• Warping: Use an enclosure, increase bed temp to 100-110°C, add a brim, and set fan to 0%
• Layer splitting/cracking: Increase nozzle temperature and ensure the enclosure is sealed
• Strong fumes: Print in a ventilated area or use a fume extractor with activated carbon filter
• Stringing: Reduce temperature slightly and tune retraction settings

Tips for Best Results

Follow these expert tips to get the best possible prints with ABS on your Elegoo Neptune 4:

• An enclosure is non-negotiable for reliable ABS prints -- even small drafts cause warping
• Preheat the bed to full temperature and let it soak for 5-10 minutes before printing
• ABS slurry (dissolved ABS in acetone) is the best adhesion method for ABS
• You can acetone-smooth ABS prints for a glossy, professional finish
• Consider ASA as an alternative if you need UV resistance -- ABS yellows in sunlight

Support Settings

For prints requiring supports with ABS, 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.
