ASA settings for the Bambu Lab A1 mini
Possible with tweaks
These are tuned starting settings for printing ASA on the Bambu Lab A1 mini. The Bambu Lab A1 mini has a direct-drive extruder and an all-metal hotend, so we set the hotend to 250°C and the bed to 80°C. ASA is the UV-stable cousin of ABS and the better choice for parts left in the sun.

Recommended ASA profile
| Hotend temperature | 250°C (tower 240–260°C) |
| Bed temperature | 80°C |
| Print speed | 63 mm/s |
| Retraction | 1 mm (direct drive) |
| Part cooling fan | 0% |
| Bed adhesion | Hot bed + enclosure; very similar to ABS. |
| Nozzle | Brass 0.4 mm is fine |
| Difficulty | Advanced |
⚠️ ASA warps without an enclosure and the Bambu Lab A1 mini is open-frame. Block drafts, raise the bed temp, and add a brim; for tall parts an enclosure is strongly recommended.
⚠️ This material prefers a 100°C bed but the Bambu Lab A1 mini tops out at 80°C; use extra adhesion help such as glue stick.
💡 Best uses for ASA: outdoor parts, UV-resistant parts.
FAQ
- What temperature should I print ASA on the Bambu Lab A1 mini?
- Start at 250°C for the hotend and 80°C for the bed, then run a temperature tower across 240–260°C to dial in your exact filament brand.
- What print speed works for ASA on this printer?
- Around 63 mm/s is a safe starting point on the Bambu Lab A1 mini. This printer can go faster once the profile is tuned, but start conservative for clean walls.
- What retraction should I use?
- Use about 1 mm of retraction (direct drive needs very little). If you see stringing with ASA, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for ASA on the Bambu Lab A1 mini?
- Yes — ASA really wants an enclosure and the Bambu Lab A1 mini is open, so expect warping on large parts without one.
