ABS settings for the Bambu Lab A1 mini
Possible with tweaks
These are tuned starting settings for printing ABS 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 245°C and the bed to 80°C. ABS warps badly without an enclosure and needs ventilation because of fumes.

Recommended ABS profile
| Hotend temperature | 245°C (tower 230–255°C) |
| Bed temperature | 80°C |
| Print speed | 70 mm/s |
| Retraction | 1 mm (direct drive) |
| Part cooling fan | 0% |
| Bed adhesion | Needs hot bed + enclosure; ABS slurry or glue helps. |
| Nozzle | Brass 0.4 mm is fine |
| Difficulty | Advanced |
⚠️ ABS 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 ABS: automotive, enclosures, heat-resistant parts.
FAQ
- What temperature should I print ABS on the Bambu Lab A1 mini?
- Start at 245°C for the hotend and 80°C for the bed, then run a temperature tower across 230–255°C to dial in your exact filament brand.
- What print speed works for ABS on this printer?
- Around 70 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 ABS, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for ABS on the Bambu Lab A1 mini?
- Yes — ABS really wants an enclosure and the Bambu Lab A1 mini is open, so expect warping on large parts without one.
