Get the Bambu Lab P1S if:
- You don’t need carbon- or glass-fiber filaments.
- You want the lower peak power draw.
- You want the lighter printer.
The short answer
Our overall pick: the Bambu Lab P2S. It does everything the P1S does and adds carbon-fiber filaments, a hotter bed and a better camera.
Lighter, lower peak power? P1S
Carbon-fiber filaments, sharper camera? P2S
Same 256 mm build volume and 300°C top nozzle temperature. The P2S raises the top speed to 600 mm/s and the bed to 110°C, ships with a hardened-steel 0.4 mm nozzle, lists carbon- and glass-fiber filaments, adds VOC and particulate filtration, and upgrades the camera to 1080p at 30 fps. The P1S is lighter and peaks at 350 W at 110 V against 1000 W for the P2S during heat-up.
Best for lower power draw
Pick the Bambu Lab P1S if
- You print PLA, PETG, ABS and ASA and don’t need carbon-fiber filaments.
- You want the lower 350 W max draw at 110 V.
- You want the lighter, slightly smaller printer: 12.95 kg.
The Amazon listing (item model P1S) is sold by Bambu Lab Store. It also offers a P1S Combo with AMS; pick the plain P1S if you don’t want the AMS.

Pick the Bambu Lab P2S if
- You want carbon- and glass-fiber grades like PLA-CF, PETG-CF and PA6-CF, with the hardened-steel nozzle included.
- You want the 110°C bed and 600 mm/s top speed.
- You want the 1080p 30 fps camera, door sensor and 5 in touchscreen.
The Amazon listing (machine only) is sold by Bambu Lab Store and ships from Amazon. The base P2S prints one color; the Combo adds AMS 2 Pro.
See the P2S on Amazon Check the P2S at BambuBefore you buy: The P2S draws up to 1000 W at 110 V for 3 to 5 minutes while heating, about 200 W steady when printing PLA. The base P2S prints one color; the Combo includes AMS 2 Pro.

The P2S wins on speed, bed temperature, nozzle, filaments, filtration and camera. The P1S wins on peak power, weight and size.
A green check marks the clearly better spec for most people. No check means a tie, a gap that depends on how you work, or a spec marked Unknown. Figures come from Bambu Lab’s spec pages and wikis; Amazon-only facts are labeled.

Spec notes and unknowns
- P2S warranty: Unknown. It isn’t on the spec page.
- P1S screen and max flow: Unknown on the maker pages we checked.
- P2S chamber up to 50°C and adaptive airflow: Amazon only.
- P2S AI error detection on its 2 TOPS NPU: the NPU is in Bambu Lab’s specs; the AI error detection claim is Amazon only.
Where the sources disagree
- P2S weight and size: Amazon lists 38.9 lb and 18 x 21 x 18 in, which look like package figures. We use Bambu Lab’s 14.9 kg and 392 x 406 x 478 mm.
- Max power: the P1S lists 350 W at 110 V; the P2S lists up to 1000 W at 110 V for a brief heat-up. They’re different measures of peak draw, not steady use.
What it can do
Common print jobs, judged only from Bambu Lab’s build volume, bed temperature and filament lists.
- Can do the maker’s specs cover it
- Just barely possible, with a limit or add-on the maker states
- Can’t the maker’s specs rule it out or don’t list it

Skip it if
Skip the P1S
Skip it if you plan to print carbon- or glass-fiber filaments; Bambu Lab doesn’t recommend them on the stock P1S.
Skip the P2S
Skip it if you only print PLA and PETG and want the lower 350 W peak power draw of the P1S.
Questions about this pair
Is the P2S faster than the P1S?
Bambu Lab lists 600 mm/s for the P2S and 500 mm/s for the P1S, with the same 20,000 mm/s² acceleration.
Can the P1S print carbon-fiber filament?
Bambu Lab doesn’t recommend carbon- or glass-fiber filaments on the P1S without a hot end and extruder upgrade. The P2S lists them and ships with a hardened-steel nozzle.
Does the base P2S print in multiple colors?
Not on its own. Multi-color needs AMS 2 Pro, included in the P2S Combo.
Does the P2S use more power?
It peaks at up to 1000 W at 110 V for 3 to 5 minutes while heating, against 350 W max for the P1S. Bambu Lab lists about 200 W steady for PLA on the P2S.
