Bambu Lab A1 — Settings Guide
The Bambu Lab A1 is a fast, reliable direct drive FDM printer that handles most filaments with minimal tuning. Its all-metal hotend reaches 300°C, supporting everything from PLA to basic Nylon. The direct drive extruder means short retraction distances (0.5-1.5mm) and excellent performance with flexible filaments like TPU.
Key Things to Know
Speed: The A1 is designed for fast printing. The recommended speeds here are conservative starting points — you can often push 150-250mm/s for PLA once you're confident your settings are dialled in. Use the "0.20mm Standard" profile in Bambu Studio as your baseline.
Open frame: Because the A1 isn't enclosed, ABS and ASA will be more prone to warping. Print these in a warm room with minimal drafts, or build a simple enclosure from a large cardboard box or IKEA LACK table enclosure.
Retraction: Direct drive means very short retraction — typically 0.5-1.0mm. If you see stringing, increase by 0.2mm at a time. Don't go above 2mm or you risk heat creep and jams.
Frequently Asked Questions
What temperature should I print PLA on the Bambu Lab A1?
Start at 210°C nozzle and 55°C bed. The A1's fast printing benefits from slightly higher temperatures than slower printers because the filament has less time to melt. If you see poor layer adhesion, increase by 5°C. If you see stringing, decrease by 5°C.
What retraction settings should I use on the A1?
Start at 0.8mm retraction distance and 30mm/s retraction speed. The A1's direct drive extruder needs very short retraction compared to Bowden printers. If you see stringing, increase distance by 0.2mm at a time. Don't exceed 2mm — longer retraction on direct drive causes more problems than it solves.
Can the Bambu Lab A1 print ABS?
Yes, but with caveats. The A1 is open-frame, so ABS tends to warp without an enclosure. Print in a warm room with no drafts, use a brim for adhesion, and set the bed to 100°C. For reliable ABS printing, consider building a simple enclosure or upgrading to the enclosed P1S.
What slicer should I use with the Bambu Lab A1?
Bambu Studio is the recommended slicer — it has built-in profiles specifically tuned for the A1 and integrates with the printer over WiFi. OrcaSlicer is an excellent alternative with more advanced features. Cura works too but requires manual profile setup. The settings on this page work in any slicer.
Can the A1 print TPU / flexible filament?
Yes — the direct drive extruder handles TPU very well. Print at 220-230°C, 50°C bed, and slow the speed to 25-30mm/s. Retraction should be minimal (0.3-0.5mm) or disabled entirely. TPU is one of the main advantages of direct drive over Bowden printers.
