Bambu Lab P1S — 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.
Enclosed chamber: The P1S can maintain 40-60°C chamber temperature, making ABS and Nylon printing reliable without any modifications. For the best results with ABS, preheat the chamber by running a short print first.
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 P1S?
Start at 210°C nozzle and 55°C bed. The P1S'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 P1S?
Start at 0.8mm retraction distance and 30mm/s retraction speed. The P1S'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 P1S print ABS?
Yes — this is where the P1S shines. The enclosed chamber maintains stable temperatures, preventing warping and cracking. Set nozzle to 245°C, bed to 100°C, fan off, and let the chamber preheat for 5-10 minutes before starting. ABS is one of the easiest filaments on the P1S.
What slicer should I use with the Bambu Lab P1S?
Bambu Studio is the recommended slicer — it has built-in profiles specifically tuned for the P1S 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 P1S 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.
