The catch
Bambu Lab P2S Combo
The build envelope matches the P1S, so oversize parts get no extra room.
Side by side
Bambu Lab P2S Combo vs Bambu Lab P1S Combo compared: The P2S step up still can't take a larger part
Quick verdict
The P2S earns the nod for its updated controls and extrusion, though the part-size limit stays the same.
Before you buy
Why, and what it costs you
A 5mm brim on a 246mm plate
A 256 × 256mm footprint is required, and it fits both P2S Combo and Bambu Lab P1S Combo. This size check doesn't tell the two apart.
Where this comes from
Take a square 246mm part with a 5mm brim on all sides. The width and depth you need = 246 + 2 × 5 = 256mm. Check each axis against the published build dimensions. Purge towers, supports and the machine's exclusion zones need their own space.
The catch
Bambu Lab P1S Combo
Color changes purge filament since the nozzle is shared.
Bambu Lab P2S Combo
- Why pick it
- A touchscreen and hardened extrusion hardware are what appeal to you
- You want AMS 2 Pro supplied as the filament system
- The catch
- The build envelope matches the P1S, so oversize parts get no extra room.
Bambu Lab P1S Combo
- Why pick it
- Your needs are already covered by the original P1S workflow
- You want the Original AMS that this Combo record lists as its filament system
- The catch
- Color changes purge filament since the nozzle is shared.

What this page compares
Weigh the P2S Combo against the P1S Combo on the color-printing setup that ships with each, material temperatures and part size before you pick a printer.

A workflow whose material requires active chamber heat
The P2S and P1S have enclosures, but neither compared record documents an active chamber heater that is separately controlled. If a workflow requires active chamber heat, look to another validated option.

Your first project has to be covered by the supplied feeder and enclosure
The original AMS is in this P1S Combo record, while P2S Combo includes AMS 2 Pro. Both are enclosed. The feeder generation that ships has to match the exact listing you buy.

Planning to print abrasive materials can change what you buy first
Hardened nozzle and extruder hardware come with the P2S. The P1S ships with a stainless nozzle, so it needs the right hardware change before it qualifies for a filament profile that requires a hardened nozzle.

Differences you will notice

How we worked this out
Take a square 246mm part with a 5mm brim on all sides. The width and depth you need = 246 + 2 × 5 = 256mm. Check each axis against the published build dimensions. Purge towers, supports and the machine's exclusion zones need their own space.
Laying out a batch of 50mm square fixtures
On a simple grid, P2S Combo holds 16 footprints and Bambu Lab P1S Combo also holds 16. Treat this as a rough screen of the plate layout before you run the real slicer.
How we worked this out
Footprints are assumed to be 50mm squares, with 10mm added to each grid cell for spacing. Count = floor(build X / 60) × floor(build Y / 60). The model includes no rotation, supports, purge tower or brim. It estimates layout only and says nothing about throughput.
Planning to print abrasive materials can change what you buy first
Hardened nozzle and extruder hardware come with the P2S. The P1S ships with a stainless nozzle, so it needs the right hardware change before it qualifies for a filament profile that requires a hardened nozzle.
How we worked this out
Whether a printer qualifies depends on what the material profile requires and what the supplied nozzle is made of. No wear-life or print-speed multiplier is inferred.
Option A
Bambu Lab, P2S Combo
P2S Combo
An enclosed CoreXY printer at 256mm, it comes with hardened extrusion hardware, a touchscreen and AMS 2 Pro. Extra controls and a drying system make ownership smoother, and the build size stays familiar for the P-series.
- Best for
- Four-color printing in an enclosure, with active filament drying
Facts we checked
- Build space of 256 × 256 × 256mm
- Nozzle maxes at 300°C, bed at 110°C
- Enclosed, but no active chamber heater is documented
- Includes AMS 2 Pro
Option B
Bambu Lab, P1S Combo
Bambu Lab P1S Combo
Build volume is 256 × 256 × 256 mm, and the print area is enclosed.
- Best for
- four-color prints and fast functional parts
Facts we checked
- It offers 256 × 256 × 256 mm of build volume.
- You get an enclosed print area.
- PLA and ABS fall within the compared materials.
- Its documented automatic setup features cover preparing for the first print.
Spec by spec
Where they really differ
| Spec | Bambu Lab P2S Combo | Bambu Lab P1S Combo | In practice |
|---|---|---|---|
| Bed temperature ceiling | 110°C | 100°C | The bed setting you need is a separate check from the nozzle setting. |
| Supplied filament system | AMS 2 Pro included | Original AMS in this Combo record | It affects what you spend on accessories and how you change materials. |
| On-machine controls | 5-inch touchscreen | 2.7-inch button-controlled screen | It changes how you handle setup and monitoring at the machine. |
| Monitoring hardware | 1080p live view with error detection | 720p camera with low-frame-rate monitoring | No camera resolution or detection feature guarantees that every failure gets caught. |
| Supplied nozzle hardware | Hardened steel nozzle and extruder gears | Stainless steel supplied nozzle | For the exact filament you plan to use, look at abrasion resistance and replacement assemblies. |
Trade-offs
What each pick costs you
With Bambu Lab P2S Combo
- Incompatible colors still need a purge because there is a single nozzle. The enclosure also lacks a separately regulated active chamber heater.
With Bambu Lab P1S Combo
- Although the chamber is enclosed, nothing actively heats it.
Change of plan
When the answer changes
A touchscreen and hardened extrusion hardware are what appeal to you
Go with Bambu Lab P2S Combo. The P2S comes with hardened nozzle and extrusion hardware and a 5-inch touchscreen. Its 256 mm cube stays the same, so choosing it is about operation and which materials you can use.
Your needs are already covered by the original P1S workflow
Go with Bambu Lab P1S Combo. The P1S Combo chosen here has the original AMS and a 256 mm cube. It stays in the running when its controls and supplied hardware are enough for the material profiles you intend to use.
Decision guide
How to decide
Go with the P2S if you value the control and extrusion updates, knowing the part-size limit does not change.
Measure your actual model
Each printer works with a 256mm cube. Because the P2S upgrades the workflow and not the size, a part the P1S cannot hold will not fit here either.
Start from the material you print
Fewer part swaps are needed for supported abrasive filaments thanks to the hardened nozzle and gears supplied with the P2S. The stainless nozzle supplied with the P1S needs a check against the exact material.
Look at the whole working setup
The exact AMS bundle is what to compare. This P1S record covers the original Combo, and the P2S comes with AMS 2 Pro. Newer P1S bundles are also sold by Bambu, so a generic Combo label tells you too little.
What this page can’t tell you
- A listed top speed will not tell you how long a finished part takes.
- Having temperature headroom shows capability but does not certify that a material will work.
- Nominal build volume leaves out the clearance that purge towers, supports and some machine routines need.
