Getting Great Prints on the Bambu Lab P1S
The P1S is the enclosed, auxiliary-fan-equipped sibling of the P1P — effectively an X1C's chamber and cooling hardware without the LiDAR and some sensing extras. For most material tuning purposes it behaves exactly like the X1C.
Is the Bambu Lab P1S enclosed?
Yes — and it does carry a dedicated auxiliary (chamber/side) part-cooling fan on top of the main print-cooling fan.
Because the P1S shares the X1C's enclosure and auxiliary-fan setup, the entire warping/ABS/ASA playbook is identical: expect similar chamber-assisted results on hot materials, and the same PLA-in-a-warm-chamber caveat on the cool end. The main practical differences from the X1C are sensing and multi-tool features, not the thermal or cooling system this guide is about.
Baseline settings for the Bambu Lab P1S
These are Bambu Studio's current stock filament-profile values (X2D-generation profiles, the same baseline every Bambu machine's Filament settings tab starts from) — treat them as the starting point for a Bambu Lab P1S, then calibrate per spool:
| Material | Nozzle | Bed (textured) | Fan max |
|---|---|---|---|
| PLA | 220 °C | 55 °C | 100 % |
| PETG | 250 °C | 70 °C | 60 % |
| ABS | 270 °C | 90 °C | 60 % |
| TPU | 230 °C | 35 °C | 100 % |
Getting the most out of the P1S specifically
Don't assume P1P forum advice applies. A lot of budget-tier troubleshooting content lumps the P1 series together, but the P1P is open-frame with no auxiliary fan and the P1S is enclosed with one — ABS/ASA advice written for a P1P (tenting, aggressive cooling limits) is more conservative than the P1S actually needs.
Chamber heat and PC/PA. The enclosure is what makes PC and PA-family filaments realistic on this machine; if warping still shows up, check that the door and top cover are actually seated — a P1S with a loose top panel loses much of its enclosure advantage.
Bed adhesion on SuperTack vs Textured PEI. Match the plate selection in the slicer to the physical plate on the bed every time you swap — the most common "why won't this stick" report on any Bambu machine. See the bed adhesion guide.
Symptoms this machine's form factor is prone to
An enclosed machine like the Bambu Lab P1S trades one set of problems for another. Warping on PLA (from chamber heat soak, not cold corners) and moisture creeping into materials during long enclosed prints are the two failure modes that catch enclosed-printer owners off guard, more often than the classic open-printer symptoms below:
- PLA-specific cooling and chamber-heat notes — read this before assuming a PLA quality issue is a fan problem.
- Filament drying guide — long enclosed prints give a marginal spool more time to reabsorb moisture mid-print.
- Layer separation — the flip side of running cooling too aggressively for a hot-chamber material.
A sane first-print checklist
- Match the plate selection in the slicer to the plate on the bed. The single most common "why won't this stick" report on any Bambu machine, this one included.
- Calibrate flow and pressure advance for anything that isn't Bambu's own filament. Generic and third-party spools can be several percent off the stock flow ratio — run the built-in calibrations from Bambu Studio's Calibration tab before trusting a new spool's first real print.
- Change one variable at a time. A print that fails after three simultaneous setting changes tells you nothing about which change mattered; the fastest route to a dialed-in Bambu Lab P1S is small, single-variable tests.

Frequently asked questions
What is the difference between the Bambu Lab P1S and the X1C?
For material tuning, essentially nothing — the P1S shares the X1C’s enclosure and auxiliary-fan setup, so the whole warping and ABS/ASA playbook is identical. The practical differences are sensing and multi-tool features, like the X1C’s LiDAR, not the thermal or cooling system. Also avoid P1P forum advice: the P1P is open-frame with no auxiliary fan, so its ABS/ASA tips are more conservative than the P1S needs.
What are the stock filament temperatures for the Bambu Lab P1S?
Bambu Studio’s stock profiles (X2D-generation) start the P1S at: PLA 220 °C nozzle, 55 °C textured bed, 100 % fan; PETG 250 °C, 70 °C, fan capped at 60 %; ABS 270 °C, 90 °C, 60 % fan; TPU 230 °C, 35 °C, 100 % fan. Treat them as a starting point and calibrate flow and pressure advance per spool for anything that isn’t Bambu’s own filament.
Can the Bambu Lab P1S print PC and PA (nylon)?
Yes — the enclosure is exactly what makes PC and PA-family filaments realistic on the P1S. If warping still shows up, check that the door and top cover are actually seated: a P1S with a loose top panel loses much of its enclosure advantage. Watch the enclosed-machine trade-offs too — PLA warping from chamber heat soak and moisture creeping into spools during long prints.
