Before You Print
Print Quality Profiles
Three presets for common use cases with ASA on the Prusa Core One L.
| 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
ASA uses the same bed adhesion methods as ABS: PEI sheet at high temperature, glue stick, or ASA/ABS slurry. A brim is recommended for larger parts to prevent warping.
Temperature Tuning Guide
Nozzle: 260°C
Range: 240-260°C. Printer max: 290°C.
- Poor layer adhesion? Increase +5°C
- Stringing or oozing? Decrease -5°C
- Print a temperature tower to find your exact sweet spot
Bed: 108°C
Range: 90-110°C. Printer max: 120°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
Troubleshooting ASA on Prusa Core One L
Pro Tips for ASA
ASA is essentially outdoor-grade ABS -- the go-to for any part exposed to sunlight
While more forgiving than ABS, an enclosure still dramatically improves print quality
Use the same post-processing techniques as ABS; ASA can be acetone-smoothed
For best UV performance, choose lighter colors which resist fading better
Store in a dry box and dry before use if the spool has been open for more than a few days
Support Settings
For prints requiring supports with ASA, 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.

ASA at a Glance
Strengths
- Best UV resistance of common filaments (10x better than ABS)
- Excellent for outdoor functional parts
- Does not yellow or become brittle in sunlight
- Good impact resistance (similar to ABS)
- Good heat resistance (softens ~100C)
Weaknesses
- Requires enclosure (like ABS)
- Emits fumes (similar to ABS)
- More expensive than ABS
- Still prone to warping without enclosure
