The Bambu Lab A2L and Qidi Tech Plus4 are cross-brand rivals: both are prosumer-tier printers, listed $230 apart. Note that the Plus4 has been replaced by the Plus5 and is no longer sold new. The Plus4 costs $230 more and gets you an enclosed chamber (with ASA, PA, PA-CF, PC and PPS-CF on its materials list) and a top speed of 600 mm/s (vs 500); the A2L answers with 32% more build volume.
First-generation product — recently released, still early days

The A2L was released on Jun 1, 2026, 164 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the A2L is the safer buy right now — it launched only 164 days ago, while the Plus4 has already been replaced by the Plus5.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The A2L lists at $469 and the Plus4 at $699 — $230 apart, so the Plus4 costs 49% more.
Per litre of build volume, that works out to $14 for the A2L versus $27 for the Plus4 — the A2L is both cheaper and roomier, so it wins on value outright.
Buy the A2L. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price.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 A2L against the Plus5.

How we judge timing and deals: read our methodology →
Bambu's largest bed-slinger build volume, big enough to print full-size helmets and large props in a single piece rather than in glued sections.
The A2L stores several calibration sets at different heights up the Z axis to keep the faint vertical banding of tall bed-slinger prints under control.
An add-on blade-cutting and pen module extends the A2L beyond printing for sticker cutting and plotting workflows.
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.
