3D printer with enclosure: which ones actually heat the chamber
Updated 2026-11-08 · Pick: QIDI Q2: $449 on qidi3d.com (checked 2026-11-06): https://dealectric.com/go/qidi-q2
Short answer. For a 3D printer with an enclosure that prints ABS and ASA, the best pick in 2026 is the QIDI Q2: a 280 W heater warms its enclosed chamber to as much as 65 °C. The Bambu Lab P2S has no chamber heater; CNC Kitchen measured 50–54 °C from bed heat alone.

What the differences mean
- The Q2's heater costs $100. The Q2 and Q2C share the same 270 × 270 × 256 mm frame. The Q2 adds the 280 W chamber heater and the 3-in-1 filter: $449 − $349 = $100.
- 15 °C more chamber headroom at the same $449. 65 °C (Q2 heater) − 50 °C (P2S passive ceiling) = 15 °C. CNC Kitchen's best P2S reading leaves a gap of 65 − 54.1 = 10.9 °C.
- 11% more build volume. Q2: 27.0 × 27.0 × 25.6 cm = 18.66 L. P2S: 25.6³ cm = 16.78 L. 18.66 ÷ 16.78 = 1.11.
- Heater energy, worst case. 280 W × a 10-hour ABS print = 2.8 kWh at most. Real use is lower once the chamber reaches temperature.
- Plus5 for big parts. 32 × 32 × 30 cm = 30.72 L, 65% more than the Q2 (30.72 ÷ 18.66 = 1.65), for $699 − $449 = $250 more.
- Adding colors later. The QIDI Box is $228 on QIDI's US store: Q2 + Box = $449 + $228 = $677.

|---|---|
| PLA and PETG only | QIDI Q2C or Bambu Lab P2S. A heated chamber adds nothing here. |
| Occasional small ABS/ASA parts | Bambu Lab P2S (measured 50–54 °C with a hot bed) or QIDI Q2 |

Heated chamber vs passive enclosure: where the warmth comes from
An enclosure only traps heat. In most enclosed printers the only heat source is the bed. In its P2S review, CNC Kitchen states plainly: 'It's not a heated chamber.' With the bed at 100–110 °C, its two in-chamber thermocouples read 50.3 °C and 54.1 °C. The P2S's flap decides where the air goes. In PLA mode a side fan pulls in cool outside air. For ABS, ASA or PC the flap closes and the printer recirculates air through a rear carbon filter.
That passive figure depends on the fan setting. Bambu forum owner Druaka logged 37–42 °C while printing ABS with the right auxiliary fan at 100%, and 50–52 °C with it off. Smaller passive boxes run cooler still. Clever Creations timed the Creality K1C's chamber rising from 25 °C to its 38 °C maximum in 30 minutes, with the lid on and all fans off. The K1C has no dedicated chamber heater.
The QIDI Q2 adds a separate 280 W PTC heater that warms the chamber independently of the bed, up to 65 °C. That figure is QIDI's rating, not a lab measurement. QIDI's own guidance says PLA usually needs no heated chamber, ABS benefits from one, PC strongly needs one, and nylon needs one in many cases. It also warns that too much chamber heat causes heat creep and sagging overhangs. So for PLA, leave the heater off.
| Printer | Chamber reading | Conditions | Who |
|---|---|---|---|
| Bambu Lab P2S | 50.3 °C and 54.1 °C | Bed at 100–110 °C, thermocouples | CNC Kitchen |
| Bambu Lab P2S | 37–42 °C | ABS, right aux fan at 100% | Bambu forum owner Druaka |
| Bambu Lab P2S | 50–52 °C | ABS, right aux fan off | Bambu forum owner Druaka |
| Creality K1C | 38 °C max, 30 min from 25 °C | Lid on, fans off | Clever Creations |
| QIDI Q2 | Up to 65 °C | Heater setpoint | QIDI rating |
Not recommended
QIDI Q2C if you are buying the enclosure for ABS or ASA. It uses the Q2's 270 × 270 × 256 mm frame and costs $100 less, but Botland's spec sheet lists its active chamber heating as 'NO' and its rated power as 350 W with no heater line. The air filter is an optional extra. For PLA and PETG it is a fair saving. For warp-prone filaments, the extra $100 for the Q2 buys the 280 W heater.
