Main trade-off
Bambu Lab P2S Combo
Its build envelope is unchanged from the P1S, so larger parts do not gain room.
Head-to-head
Choose the P2S for the controls and extrusion updates, with the same part-size limit.
Before you choose
The required 256 × 256mm footprint fits P2S Combo and fits Bambu Lab P1S Combo. This particular size check does not separate them.
What this is based on
Assume a square 246mm part with a 5mm brim on every side. Required width and depth = 246 + 2 × 5 = 256mm. Compare each axis with the published build dimensions. Purge towers, supports and machine exclusion zones need separate space.
Main trade-off
Its build envelope is unchanged from the P1S, so larger parts do not gain room.
Main trade-off
Its shared nozzle purges filament during color changes.


Compare P2S Combo and P1S Combo by part size, material temperatures and the supplied color-printing setup before choosing your printer.
Choose the P2S for the controls and extrusion updates, with the same part-size limit.
Winner by situation
The required 256 × 256mm footprint fits P2S Combo and fits Bambu Lab P1S Combo. This particular size check does not separate them.
The P2S and P1S are enclosed, but neither compared record documents a separately controlled active chamber heater. A workflow requiring active chamber heat needs another validated option.
P2S Combo includes AMS 2 Pro, while this P1S Combo record includes the original AMS. Both are enclosed, but the supplied feeder generation must match the exact listing.
The P2S includes hardened nozzle and extruder hardware. A P1S with its supplied stainless nozzle needs the appropriate hardware change before a filament profile requiring a hardened nozzle is eligible.
What matters in practice
The required 256 × 256mm footprint fits P2S Combo and fits Bambu Lab P1S Combo. This particular size check does not separate them.
Assume a square 246mm part with a 5mm brim on every side. Required width and depth = 246 + 2 × 5 = 256mm. Compare each axis with the published build dimensions. Purge towers, supports and machine exclusion zones need separate space.
A simple grid holds 16 footprints on P2S Combo and 16 on Bambu Lab P1S Combo. Use this as a plate-layout screen before running the actual slicer.
Assume 50mm square footprints plus 10mm allowance per grid cell for spacing. Count = floor(build X / 60) × floor(build Y / 60). No rotation, supports, purge tower or brim is modeled. This estimates layout, not throughput.
The P2S includes hardened nozzle and extruder hardware. A P1S with its supplied stainless nozzle needs the appropriate hardware change before a filament profile requiring a hardened nozzle is eligible.
Eligibility follows the material profile requirement and supplied nozzle material. No wear-life or print-speed multiplier is inferred.

Bambu Lab, P2S Combo
An enclosed 256mm CoreXY printer with AMS 2 Pro, a touchscreen and hardened extrusion hardware. The added controls and drying system improve the ownership workflow while keeping the familiar P-series build size.

Bambu Lab, P1S Combo
The printer provides 256 × 256 × 256 mm build volume. The print area is enclosed.
Meaningful differences
| What changes | Bambu Lab P2S Combo | Bambu Lab P1S Combo | Why it matters |
|---|---|---|---|
| Bed temperature ceiling | 110°C | 100°C | Check the required bed setting separately from the nozzle setting. |
| Supplied filament system | AMS 2 Pro included | Original AMS in this Combo record | This changes the accessory bill and material-change process. |
| On-machine controls | 5-inch touchscreen | 2.7-inch button-controlled screen | This changes direct setup and monitoring interaction. |
| Monitoring hardware | 1080p live view with error detection | 720p camera with low-frame-rate monitoring | Camera resolution and detection features do not guarantee every failure is caught. |
| Supplied nozzle hardware | Hardened steel nozzle and extruder gears | Stainless steel supplied nozzle | Check abrasion resistance and replacement assemblies for the exact filament. |
What you give up
Recommendation switch
Choose Bambu Lab P2S Combo. P2S supplies hardened nozzle and extrusion hardware plus a 5-inch touchscreen. Its 256 mm cube is unchanged, so this choice addresses operation and compatible materials.
Choose Bambu Lab P1S Combo. The selected P1S Combo has the original AMS and a 256 mm cube. Keep it in consideration when its controls and supplied hardware meet the intended material profiles.
What matters in practice
Both printers use a 256mm cube. The P2S is a workflow upgrade, so a part that is too large for the P1S remains too large here.
The P2S supplied hardened nozzle and gears reduce the need to change parts for supported abrasive filaments. The P1S supplied stainless nozzle must be checked against the exact material.
Compare the exact AMS bundle. This P1S record refers to the original Combo, while the P2S includes AMS 2 Pro. Bambu also sells newer P1S bundles, so a generic Combo label is insufficient.
