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 Creality K2 Pro Combo compared: K2 Pro holds a larger part inside a heated chamber
Quick verdict
For a larger heated chamber, the K2 Pro is the one. For a smaller enclosed workflow, take the P2S.
Before you buy
Why, and what it costs you
A 5mm brim on a 275mm plate
The footprint you need is 285 × 285mm, which is more than P2S Combo offers but fits K2 Pro Combo. That can spare you from splitting the flat part.
Where this comes from
Take a square 275mm part with a 5mm brim on all sides. The width and depth you need = 275 + 2 × 5 = 285mm. Check each axis against the published build dimensions. Purge towers, supports and the machine's exclusion zones need their own space.
The catch
Creality K2 Pro Combo
At 300°C, its nozzle tops out below the 350°C limit of the K2 Plus.
Bambu Lab P2S Combo
- Why pick it
- AMS 2 Pro appeals to you and your parts fit inside a 256mm cube
- You are comfortable with No active heater documented under active chamber heating
- The catch
- The build envelope matches the P1S, so oversize parts get no extra room.
Creality K2 Pro Combo
- Why pick it
- Your job requires active chamber heating or a 300mm envelope
- Active chamber heating at 60°C is what you want
- The catch
- At 300°C, its nozzle tops out below the 350°C limit of the K2 Plus.

What this page compares
Look at the color-printing setup in the box, material temperatures and part size before you buy, since those are where the P2S Combo and K2 Pro Combo differ.
For a larger heated chamber, the K2 Pro is the one. For a smaller enclosed workflow, take the P2S.
Which one fits
Pick the situations that sound like you
A 275mm flat part that needs a 5mm brim
The footprint you need is 285 × 285mm, which is more than P2S Combo offers but fits K2 Pro Combo. That can spare you from splitting the flat part.

- Not suitable
- Creality K2 Pro Combo
- Better fit
A workflow whose material requires active chamber heat
K2 Pro's chamber heater is rated to 60°C. No active chamber heater is documented for the P2S, so its enclosure alone can't show the same controlled-temperature capability.

- Caution
- Creality K2 Pro Combo
- Better fit
Your first project has to be covered by the supplied feeder and enclosure
AMS 2 Pro is included with P2S Combo, and K2 Pro Combo includes one four-slot CFS. Both have enclosures, but only K2 Pro has documented active chamber heating.

A stated 55°C chamber condition sets the two apart
If a filament workflow explicitly calls for a controlled 55°C chamber, it sits within the K2 Pro published 60°C chamber limit. The P2S has no active chamber-heater specification that would certify that requirement.

In practice
Differences you will notice
A 5mm brim on a 275mm plate
The footprint you need is 285 × 285mm, which is more than P2S Combo offers but fits K2 Pro Combo. That can spare you from splitting the flat part.
How we worked this out
Take a square 275mm part with a 5mm brim on all sides. The width and depth you need = 275 + 2 × 5 = 285mm. 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 70mm square fixtures
On a simple grid, P2S Combo holds 9 footprints and K2 Pro Combo also holds 9. 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 70mm squares, with 10mm added to each grid cell for spacing. Count = floor(build X / 80) × floor(build Y / 80). The model includes no rotation, supports, purge tower or brim. It estimates layout only and says nothing about throughput.
A stated 55°C chamber condition sets the two apart
If a filament workflow explicitly calls for a controlled 55°C chamber, it sits within the K2 Pro published 60°C chamber limit. The P2S has no active chamber-heater specification that would certify that requirement.
How we worked this out
The active chamber setting needed is 55°C. K2 Pro ceiling minus requirement = 60 minus 55 = 5°C. This tests whether the setpoint qualifies. It does not test whether temperature is uniform or the print succeeds.
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
Creality, K2 Pro Combo
K2 Pro Combo
This enclosed CoreXY printer has a 300mm build size, a four-slot CFS and a 60°C active chamber. Pick it for bigger functional parts and multicolor jobs that stay under the K2 Plus size.
- Best for
- Active chamber heat plus a 300mm part envelope
Facts we checked
- Build space of 300 × 300 × 300mm
- Nozzle maxes at 300°C, bed at 110°C
- Chamber actively heated to 60°C
- Includes one four-slot CFS
Spec by spec
Where they really differ
| Spec | Bambu Lab P2S Combo | Creality K2 Pro Combo | In practice |
|---|---|---|---|
| Build envelope | 256 × 256 × 256mm | 300 × 300 × 300mm | The one-piece model, its supports and the adhesion margin all have to fit. |
| Active chamber heating | No active heater documented | 60°C | Thermal control comes differently from an enclosure than from a regulated chamber heater. |
| Supplied filament system | AMS 2 Pro included | One four-slot CFS included | It affects what you spend on accessories and how you change materials. |
| On-machine controls | 5-inch touchscreen | 4-inch touchscreen | It changes how you handle setup and monitoring at the machine. |
| Monitoring hardware | 1080p live view with error detection | Chamber camera plus nozzle camera | No camera resolution or detection feature guarantees that every failure gets caught. |
| Supplied nozzle hardware | Hardened steel nozzle and extruder gears | Hardened-tip nozzle for specified abrasive filaments | 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 Creality K2 Pro Combo
- Only one four-slot CFS comes with the Combo. Reaching the 16 colors in the advertising requires extra CFS units.
Change of plan
When the answer changes
AMS 2 Pro appeals to you and your parts fit inside a 256mm cube
Go with Bambu Lab P2S Combo. The P2S gives you AMS 2 Pro and a 256 mm cube. Look at the entire sliced footprint, brim and purge structures included, and pick it only if you don't need active chamber heating.
Your job requires active chamber heating or a 300mm envelope
Go with Creality K2 Pro Combo. K2 Pro offers a 300 mm cube and a chamber heater rated to 60°C. A 275 mm square fixture with the assumed 5 mm brim on each side fits its nominal plate, which is more than P2S allows.
Decision guide
How to decide
A larger heated chamber means the K2 Pro. A smaller enclosed workflow means the P2S.
Check your model against the dimensions
Before any adhesion margin is added, a 275mm square fixture is already bigger than the P2S plate. If that fixture has to stay one flat piece, the K2 Pro is the practical choice.
Let the material set the requirements
The K2 Pro actively heats its chamber up to 60°C. The P2S instead manages airflow and retained heat, which is not the same control system as a dedicated chamber heater.
Compare the full working setup
Four filament positions feed a single nozzle in both Combos at the start. More color changes still cost purging and extra time, so compare sliced production files from each before you estimate job cost.
What this page can’t tell you
- Top published speeds do not predict how long a finished part will take.
- More temperature headroom is a capability check. It does not prove that a material is compatible.
- Clearance for supports, purge towers and certain machine routines never shows up in the nominal build volume.
