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 Anycubic Kobra S1 Combo compared: P2S fits a slightly larger part, S1 heats the bed higher
Quick verdict
A hotter bed and active drying are what the S1 stresses. The P2S counters with a slightly larger cube.
Before you buy
Why, and what it costs you
A 5mm brim on a 245mm plate
The footprint you need is 255 × 255mm. It fits P2S Combo and is too large for Anycubic Kobra S1 Combo, which can avoid splitting the flat part.
Where this comes from
Take a square 245mm part with a 5mm brim on all sides. The width and depth you need = 245 + 2 × 5 = 255mm. Check each axis against the published build dimensions. Purge towers, supports and the machine's exclusion zones need their own space.
The catch
Anycubic Kobra S1 Combo
Color changes create waste with only a single nozzle.
Bambu Lab P2S Combo
- Why pick it
- You need Bambu controls along with the 256mm envelope
- Your target nozzle temperature ceiling is 300°C
- The catch
- The build envelope matches the P1S, so oversize parts get no extra room.
Anycubic Kobra S1 Combo
- Why pick it
- You depend on the S1 120°C bed specification
- Your target nozzle temperature ceiling is 320°C
- The catch
- Color changes create waste with only a single nozzle.

What this page compares
Here the P2S Combo and Kobra S1 Combo are compared on how big a part you can print, how hot materials can run and the supplied color-printing setup, to help you choose a printer.

A 245mm flat part that needs a 5mm brim
The footprint you need is 255 × 255mm. It fits P2S Combo and is too large for Anycubic Kobra S1 Combo, which can avoid splitting the flat part.

A workflow whose material requires active chamber heat
In the compared specifications, active chamber heating is documented for neither P2S nor Kobra S1. The filament dryers inside their feeder systems don't warm the print chamber.

Your first project has to be covered by the supplied feeder and enclosure
P2S Combo comes with AMS 2 Pro, and Kobra S1 Combo comes with ACE Pro, which has active drying up to 55°C. Both are enclosed, and each uses one nozzle for the supplied multicolor workflow.

A 115°C bed profile falls within just one published limit
A specified 115°C setting sits 5°C under the S1 bed ceiling of 120°C. The P2S bed ceiling of 110°C is 5°C short of it. The part and filament still have to suit the enclosure and nozzle.

In practice
Differences you will notice
A 5mm brim on a 245mm plate
The footprint you need is 255 × 255mm. It fits P2S Combo and is too large for Anycubic Kobra S1 Combo, which can avoid splitting the flat part.
How we worked this out
Take a square 245mm part with a 5mm brim on all sides. The width and depth you need = 245 + 2 × 5 = 255mm. 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 55mm square fixtures
On a simple grid, P2S Combo holds 9 footprints and Anycubic Kobra S1 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 55mm squares, with 10mm added to each grid cell for spacing. Count = floor(build X / 65) × floor(build Y / 65). The model includes no rotation, supports, purge tower or brim. It estimates layout only and says nothing about throughput.
A 115°C bed profile falls within just one published limit
A specified 115°C setting sits 5°C under the S1 bed ceiling of 120°C. The P2S bed ceiling of 110°C is 5°C short of it. The part and filament still have to suit the enclosure and nozzle.
How we worked this out
The bed requirement assumed is 115°C. 120 minus 115 = 5°C. 110 minus 115 = negative 5°C. Bed surface temperature and material results have not been measured here.
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
Anycubic, Kobra S1 Combo
Anycubic Kobra S1 Combo
An enclosed print area holds a 250 × 250 × 250 mm build volume.
- Best for
- four-color prints and speedy functional parts
Facts we checked
- The printer provides 250 × 250 × 250 mm build volume.
- You get an enclosed print area.
- PLA and ABS fall within the compared materials.
- Before your first print, read the setup and calibration instructions for the exact model.
Spec by spec
Where they really differ
| Spec | Bambu Lab P2S Combo | Anycubic Kobra S1 Combo | In practice |
|---|---|---|---|
| Build envelope | 256 × 256 × 256mm | 250 × 250 × 250mm | The one-piece model, its supports and the adhesion margin all have to fit. |
| Nozzle temperature ceiling | 300°C | 320°C | Stay within this limit with whichever filament profile you pick. |
| Bed temperature ceiling | 110°C | 120°C | The bed setting you need is a separate check from the nozzle setting. |
| Supplied filament system | AMS 2 Pro included | ACE Pro with active drying up to 55°C included | It affects what you spend on accessories and how you change materials. |
| On-machine controls | 5-inch touchscreen | 4.3-inch touchscreen | It changes how you handle setup and monitoring at the machine. |
| Monitoring hardware | 1080p live view with error detection | AI spaghetti detection and monitoring | No camera resolution or detection feature guarantees that every failure gets caught. |
| Supplied nozzle hardware | Hardened steel nozzle and extruder gears | Quick-release hotend | 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 Anycubic Kobra S1 Combo
- Nothing actively heats the chamber.
Change of plan
When the answer changes
You need Bambu controls along with the 256mm envelope
Go with Bambu Lab P2S Combo. Over Kobra S1, the P2S gains 6 mm on each axis. Its AMS 2 Pro and controls fit a buyer who already likes that workflow and whose bed requirement stays within 110°C.
You depend on the S1 120°C bed specification
Go with Anycubic Kobra S1 Combo. The bed ceiling is 120°C on Kobra S1 and 110°C on P2S. A 115°C bed profile is within S1's published limit but fails the P2S limit, as long as the rest of the material requirements fit too.
Decision guide
How to decide
Hotter bed and active drying favor the S1, and a slightly larger cube favors the P2S.
Compare real part dimensions
That 6mm gap on each axis only counts when a part is near the limit. If a project has a brim, supports or a purge tower, check its full sliced footprint.
Match limits to your material
Published figures for the S1 are a 320°C nozzle and a 120°C bed, against 300°C and 110°C for the P2S. Pick the real filament profile first, then decide whether the higher limits help.
Compare everything you will work with
ACE Pro on the S1 can feed supported multicolor materials and dries filament at up to 55°C. Because Anycubic excludes standard TPU95A from ACE Pro, flexible jobs must use the direct-feed instructions.
What this page can’t tell you
- You cannot predict finished-part time from published speed ceilings.
- Temperature headroom checks capability only and does not certify that a material is compatible.
- The nominal build volume does not count the room that certain machine routines, supports and purge towers need.
