PETG settings for the Bambu Lab A1 mini
Great match
These are tuned starting settings for printing PETG 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 240°C and the bed to 80°C. PETG is strong and weather-resistant but strings easily, so tune retraction and keep the fan low.

FAQ
- What temperature should I print PETG on the Bambu Lab A1 mini?
- Start at 240°C for the hotend and 80°C for the bed, then run a temperature tower across 230–250°C to dial in your exact filament brand.
- What print speed works for PETG 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 1.5 mm of retraction (direct drive needs very little). If you see stringing with PETG, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for PETG on the Bambu Lab A1 mini?
- No, PETG prints fine in the open on the Bambu Lab A1 mini.
