The Plus4 and Q2 are both prosumer-tier printers from Qidi Tech, so the brand and ecosystem question is already settled — this comes down to size, features and price. Note that the Plus4 has been replaced by the Plus5 and is no longer sold new. Both are enclosed CoreXY printers with 4-slot multicolor, a 600 mm/s rated top speed and automatic calibration. The Plus4 costs $200 more and gets you 40% more build volume and extra engineering materials (PPS-CF).
This printer is no longer sold new. It has been replaced by the Qidi Tech Plus5.
Best for: Makers and small businesses who need a large enclosed build volume for engineering materials at a prosumer price — particularly those printing PA-CF, ABS, and PC at scale. Look for clearance deals — the Plus5 is the current model.

Best for: Makers and engineers who need reliable printing in ABS, ASA, PA, or carbon-fiber composites and want the best-value enclosed printer under $500.

The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
The Q2 was released on Aug 20, 2025, 449 days ago. Its previous release cycle ran about 518 days, so it is 87% of the way through — roughly 69 days before a successor would be due at that pace.
On timing alone, the Q2 is the safer buy right now — it is late in its cycle (87% through), while the Plus4 has already been replaced by the Plus5.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Q2 lists at $499 and the Plus4 at $699 — $200 apart, so the Plus4 costs 40% more.
Per litre of build volume, that works out to $27 for the Plus4 versus $27 for the Q2 — the Q2 is the better value per litre as well.
Buy the Q2. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price. If the Plus4 appealed to you, the fair comparison today is the Q2 against the Plus5.

One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
The Q2 actively heats the print chamber — not just passively traps heat. This is the key differentiator for reliable ABS, ASA, PA-CF, and PC printing without warping.
Triple-stage filtration removes 99.5% of particulates and VOCs — essential for printing ABS and ASA in a home or office environment.
Handles the full spectrum of engineering filaments including carbon and glass fiber composites without a hotend upgrade.
