ABS settings for the Bambu Lab P1S
Great match
These are tuned starting settings for printing ABS on the Bambu Lab P1S. The Bambu Lab P1S has a direct-drive extruder and an all-metal hotend in an enclosed chamber, so we set the hotend to 245°C and the bed to 100°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 | 100°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. |

| Difficulty | Advanced |
💡 Best uses for ABS: automotive, enclosures, heat-resistant parts.
FAQ
- What temperature should I print ABS on the Bambu Lab P1S?
- Start at 245°C for the hotend and 100°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 P1S. 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 P1S?
- The Bambu Lab P1S is enclosed, which is exactly what ABS needs for warp-free prints.
