PETG on the Bambu Lab A1 Mini
Yes, with a couple of cautions. The A1 shrunk to a desk-friendly size. Same brains, smaller bed.
PETG works on the Bambu Lab A1 Mini, mind a couple of things
Use the lower end of the bed rangePrinter
Some PETG spools ask for up to 85 °C on the bed; the Bambu Lab A1 Mini reaches 80 °C. Set the bed near 80 °C and add a glue stick if corners lift.
Keep the spool dryMaterial
PETG soaks up moisture from the air, and damp filament prints rough and stringy. If that happens, dry the spool at 60-70 °C for 4-6 h and store it sealed with desiccant.
Buying the CF version of PETG?
Carbon-fiber filament sands down the Bambu Lab A1 Mini’s stock nozzle. Plain PETG is fine; for the CF variant, fit a hardened steel nozzle first (a cheap swap).
Safe starting ranges for PETG as a family, not gospel. Each spool below has its exact manufacturer numbers, the dated source, and one-click slicer settings on its page.
