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 QIDI Q2 Combo compared: Q2 has room for a wider part and adds active chamber heat
Quick verdict
For active heat and extra bed width, go with the Q2. For the Bambu workflow, go with the P2S.
Before you buy
Why, and what it costs you
A 5mm brim on a 260mm plate
A 270 × 270mm footprint is required. That is more than P2S Combo offers and fits Q2 Combo, which can avoid splitting the flat part.
Where this comes from
Take a square 260mm part with a 5mm brim on all sides. The width and depth you need = 260 + 2 × 5 = 270mm. Check each axis against the published build dimensions. Purge towers, supports and the machine's exclusion zones need their own space.
The catch
QIDI Q2 Combo
For tall parts, the 256mm Z height may be what runs out first.
Bambu Lab P2S Combo
- Why pick it
- Bambu profiles and the AMS 2 Pro system are your preference
- A 300°C nozzle temperature ceiling is what you want
- The catch
- The build envelope matches the P1S, so oversize parts get no extra room.
QIDI Q2 Combo
- Why pick it
- Your needs include a heated chamber and a higher nozzle ceiling
- You are after a nozzle temperature ceiling of 370°C
- The catch
- For tall parts, the 256mm Z height may be what runs out first.

Which one fits
Pick the situations that sound like you
A 260mm flat part that needs a 5mm brim
A 270 × 270mm footprint is required. That is more than P2S Combo offers and fits Q2 Combo, which can avoid splitting the flat part.
- Bambu Lab P2S Combo
- Not suitable
- QIDI Q2 Combo
- Better fit
A workflow whose material requires active chamber heat
Q2's active chamber heater is rated to 65°C. For the compared configuration, no separately regulated active chamber heater is documented for the P2S.

- Caution
- QIDI Q2 Combo
- Better fit
Your first project has to be covered by the supplied feeder and enclosure
AMS 2 Pro comes with P2S Combo, and Q2 Combo comes with a four-slot QIDI Box with active drying. Both have enclosures, but only Q2 documents active chamber heating.

A 330°C nozzle profile is beyond what the P2S allows
Q2's published ceiling of 370°C sits 40°C above a specified 330°C nozzle profile. The P2S ceiling of 300°C is 30°C under that setting, so it fails this temperature check.

A 5mm brim on a 260mm plate
A 270 × 270mm footprint is required. That is more than P2S Combo offers and fits Q2 Combo, which can avoid splitting the flat part.
How we worked this out
Take a square 260mm part with a 5mm brim on all sides. The width and depth you need = 260 + 2 × 5 = 270mm. 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 60mm square fixtures
On a simple grid, P2S Combo holds 9 footprints and Q2 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 60mm squares, with 10mm added to each grid cell for spacing. Count = floor(build X / 70) × floor(build Y / 70). The model includes no rotation, supports, purge tower or brim. It estimates layout only and says nothing about throughput.
A 330°C nozzle profile is beyond what the P2S allows
Q2's published ceiling of 370°C sits 40°C above a specified 330°C nozzle profile. The P2S ceiling of 300°C is 30°C under that setting, so it fails this temperature check.
How we worked this out
The example requirement is 330°C. 370 minus 330 = 40°C. 300 minus 330 = negative 30°C. It is one necessary condition and not a general claim about filament compatibility.
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
QIDI, Q2 Combo
Q2 Combo
A 65°C chamber, a 370°C nozzle and a 270 × 270 × 256mm envelope define the Q2. The Combo adds QIDI Box, which handles supported multicolor jobs and actively dries filament.
- Best for
- Technical filaments in a compact heated-chamber printer
Facts we checked
- Build space of 270 × 270 × 256mm
- Nozzle maxes at 370°C, bed at 120°C
- Chamber actively heated to 65°C
- Includes a four-slot QIDI Box with active drying
Spec by spec
Where they really differ
| Spec | Bambu Lab P2S Combo | QIDI Q2 Combo | In practice |
|---|---|---|---|
| Build envelope | 256 × 256 × 256mm | 270 × 270 × 256mm | The one-piece model, its supports and the adhesion margin all have to fit. |
| Nozzle temperature ceiling | 300°C | 370°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. |
| Active chamber heating | No active heater documented | 65°C | Thermal control comes differently from an enclosure than from a regulated chamber heater. |
| Supplied filament system | AMS 2 Pro included | Four-slot QIDI Box with active drying 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 monitoring camera | No camera resolution or detection feature guarantees that every failure gets caught. |
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 QIDI Q2 Combo
- Nozzle heat by itself does not make a material compatible. Look up the exact material's nozzle, drying and ventilation requirements.
Change of plan
When the answer changes
Bambu profiles and the AMS 2 Pro system are your preference
Go with Bambu Lab P2S Combo. P2S pairs the Bambu workflow with AMS 2 Pro in a 256 mm cube. Make sure its 300°C nozzle ceiling and the absence of a documented active chamber heater suit your material.
Your needs include a heated chamber and a higher nozzle ceiling
Go with QIDI Q2 Combo. Q2 gives you a 65°C active chamber and a 370°C nozzle ceiling. Its 270 × 270 × 256 mm envelope adds horizontal room too, with the Z limit unchanged.
Decision guide
How to decide
The Q2 brings active heat and a wider bed. The P2S brings the Bambu workflow.
Size up the actual model
Each horizontal axis gains 14mm on the Q2 bed, while the maximum height stays at 256mm. That helps wide plates and does nothing for tall models.
Match the printer to your material
A 65°C chamber and a 370°C nozzle ceiling are what the Q2 offers. They matter once you have picked a technical filament, and drying, nozzle compatibility and ventilation still need their own check.
Weigh the complete setup
A 5-inch touchscreen is part of the P2S, along with Bambu’s flow-calibration workflow. Choose based on the software and material work you do each week, because camera and interface features do not make the printed part any bigger.
What this page can’t tell you
- Speed ceilings on a spec sheet cannot tell you the time for a finished part.
- Temperature headroom tells you what a printer can do. It does not certify that a material is compatible.
- Nominal build volume ignores the space certain machine routines, supports and purge towers need.
