13 of 13 answers for the Bambu Lab P1S are verified against Bambu Lab's published documents, each with its source and date. Checked against Bambu Lab's published documents on 5 October 2026. We have not physically tested this.
Verification means the maker's own page was opened and the quoted words appear on it. It is not a physical test. How we verify.
The maker lists PLA as ideal for the P1S.
Supported Filament Ideal: PLA, PETG, TPU, PVA, PET Capable: PA, PC, ABS, ASA Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA Capable: PA, PC
The maker lists PETG as ideal for the P1S.
Supported Filament Ideal: PLA, PETG, TPU, PVA, PET Capable: PA, PC, ABS, ASA Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA Capable: PA, PC
The maker lists TPU as ideal for the P1S.
Supported Filament Ideal: PLA, PETG, TPU, PVA, PET Capable: PA, PC, ABS, ASA Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA Capable: PA, PC
Bambu recommends an enclosed printer for ABS and ASA and names the P1S as one.
ABS, ASA, PC, PA, and their CF/GF reinforced materials
Require higher heatbed and chamber temperatures to suppress warping and layer separation
Enclosed printer ( Bambu H2 Series, X2D, P2S, X1, X1C, P1S, etc. )
The maker lists PA as capable, not ideal, for the P1S.
Supported Filament Ideal: PLA, PETG, TPU, PVA, PET Capable: PA, PC, ABS, ASA Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA Capable: PA, PC

Bambu does not recommend printing fibre-reinforced filament on the P1S directly.
it is not recommended to directly print fiber-reinforced filaments such as glass fiber or carbon fiber, before an extruder and hotend upgrade is done
The nozzle can be replaced as a Hotend with Nozzle or as a Complete Hotend Assembly; both are made for the X1 and P1 series.
If you need to change the nozzle, you can either replace the Hotend with Nozzle or the entire Complete Hotend Assembly.
The P1S ships with a 0.4 mm stainless steel nozzle.
P1S comes standard with a 0.4mm stainless steel nozzle, X1C comes standard with a 0.4mm hardened steel nozzle
For carbon and glass-fibre filament Bambu says not to use stainless steel or brass nozzles; the P1S stock nozzle is stainless steel.
When printing carbon fiber or glass fiber-reinforced materials
Do not use a stainless steel or brass nozzle. Their hardness is insufficient, so they wear out quickly
P1S comes standard with a 0.4mm stainless steel nozzle, X1C comes standard with a 0.4mm hardened steel nozzle
Inside the P1S, above the toolhead, the maker lists one 550 mm tube, 2.0 mm inner and 4.0 mm outer diameter. PTFE tube carries the filament from the AMS or the external spool holder to the extruder, which is inside the toolhead. Bambu recommends replacing the tube every two months under normal use, and inspecting it every month with highly abrasive filaments such as carbon fibre or glow-in-the-dark.
X1 / P1 Tube Location Qty Length ID / OD Inside X1 / P1S printer, above the toolhead 1 550 mm 2.0 / 4.0 mm
routing it from the Automatic Material System (i.e. AMS) or the external spool holder to the extruder inside the printer toolhead
Under normal usage, we recommend replacing the tube every two months
When printing with highly abrasive filaments (such as carbon fiber or glow-in-the-dark filaments), we recommend inspecting the tube every month
The P1S comes with a Textured PEI Plate pre-installed on the hotbed.
Textured PEI Plate (pre-installed on the hotbed)
The X1 and P1 series use a spring belt tensioner: loosen the 4 screws, move the toolhead back and forth, retighten, and the spring sets the tension.
Applicable Printer Models X1 Series P1 Series ... The spring system in the belt-tensioner will tighten the belt to the correct tension.
The model name is printed on the front of the printer and shown on its screen.
