Before You Print
Print Quality Profiles
Three presets for common use cases with ABS on the Bambu Lab A1 Combo.
| Profile | Layer Height | Speed | Infill | Best For |
|---|---|---|---|---|
| Draft | 0.28mm | 200 mm/s | 10-15% | Rapid prototyping, test fits |
| Standard | 0.20mm | 140 mm/s | 15-20% | General purpose, everyday prints |
| Quality | 0.12mm | 80 mm/s | 20-30% | Miniatures, display pieces, fine detail |
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.
Temperature Tuning Guide
Nozzle: 255°C
Range: 230-260°C. Printer max: 300°C.
- Poor layer adhesion? Increase +5°C
- Stringing or oozing? Decrease -5°C
- Print a temperature tower to find your exact sweet spot
Bed: 100°C
Range: 95-110°C. Printer max: 100°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
Troubleshooting ABS on Bambu Lab A1 Combo
Pro Tips for ABS
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.
