What to feed the Bambu Lab A1 Mini
Same appetite, smaller plate
The Mini eats what its big sibling eats: PLA, PETG, and TPU. The difference is the 180 x 180 x 180 mm build volume, which makes it a machine for parts, not helmets. Split large projects into pieces.
Watch the bed ceiling
The bed tops out at 80 °C. PLA (50-60 °C) and TPU (40-60 °C) never notice. PETG likes 70-85 °C, so the Mini runs it at the top of what it can offer. It works; there's just no margin left to add.
A good first spool
Bambu's PLA Basic, tuned for the family's stock profiles. Their PETG Basic (230-260 °C with a 65-75 °C bed, by their own sheet) is the natural second, and those bed numbers suit the Mini nicely.
