Bambu Lab
Bambu Lab A1 mini
FDM printer with a 180 × 180 × 180 mm build volume and 1.75 mm filament. The bed reaches 80 °C; documentation lists PLA, PETG, TPU and PVA as ideal materials.
Assessed from documentation Updated on October 4, 2026
How to recognize it: Confirm the name says A1 mini. Its bed is smaller than the A1 bed; AMS lite does not change the printer model.
