ASA and ABS Warping Enclosure Guide
ASA and ABS fail when the part cools unevenly. The fix path is heat stability: enclosure, bed temperature, draft control, part orientation, brim strategy, and slower cooling.
What this problem usually looks like
- Corners lift even with good first layer
- Tall parts crack or split between layers
- Edges curl upward during long prints
- Part sticks at first then releases later
- Surface gets rough near drafty areas
Most likely causes
- Printer is not enclosed or room has drafts
- Bed temperature is too low or inconsistent
- Cooling fan is too high
- Part has sharp corners and large flat base
- Material is wet or poor quality
Step-by-step fix order
- Use an enclosure or draft shield before changing many slicer settings
- Clean the bed and use a brim around sharp corners
- Raise bed temperature within material limits
- Reduce part cooling and avoid sudden room airflow
- Orient parts to reduce long flat stress lines
Settings and checks to record
| Setting or check | What to do |
|---|---|
| Bed temp | Use a higher stable bed temperature for ASA/ABS than PLA/PETG |
| Cooling | Use low or no fan unless detail requires it |
| Brim | Use a wide brim for large or sharp-cornered parts |
| Enclosure | Aim for consistent chamber warmth, not extreme heat |

When to stop and ask AI Doctor
If you have already followed the steps above and the failure keeps changing, write down the exact symptom, filament, nozzle size, temperature, speed, slicer, and printer model, then run it through the AI Print Doctor. Intermittent problems often need a symptom-by-symptom diagnosis rather than one generic setting change.
