The Bambu Lab A1 (Bambu Lab) has a direct-drive extruder, an all-metal hotend, with a 300°C max hotend and 100°C max bed (256 × 256 × 256 mm). Of 14 common filaments, 9 are a great match on this hardware out of the box.
What filaments does the Bambu Lab A1 support? The Bambu Lab A1 supports 9 filaments out of the box and can handle 5 more with tweaks (usually an enclosure or slower speed). Its all-metal hotend, direct-drive extruder and 100°C bed decide what it can run.

FAQ
What filaments does the Bambu Lab A1 support?
Can the Bambu Lab A1 print PETG?
Yes. PETG prints well on the Bambu Lab A1 at about 240°C hotend and 80°C bed. See the full Bambu Lab A1 PETG profile.
Can the Bambu Lab A1 print ABS or ASA?
The Bambu Lab A1 is open-frame, so ABS and ASA are possible but will warp on larger parts without an enclosure or draft shield. The hotend can reach the temperatures needed.
Does the Bambu Lab A1 need an all-metal hotend for high-temp filament?
No — the Bambu Lab A1 already has an all-metal hotend, so it can safely reach the temperatures needed for ABS, ASA, PC and nylon (within its 300°C limit).
