The Bambu Lab A2L (prosumer) and Qidi Tech Max4 (professional) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. The Max4 costs $580 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 800 mm/s (vs 500).
First-generation product — recently released, still early days
Best for: Makers who want the largest possible open-frame build volume on a budget — large cosplay, terrain, and functional parts — with optional multicolor via AMS Lite.

Best for: Professional makers and small studios who need the maximum enclosed build volume in Qidi's lineup for large engineering parts, architectural models, or batch production — at a price point below the Bambu H2S.

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 Max4 was released on Dec 1, 2025, 346 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
Both are early enough in their cycles that timing should not decide this one. The A2L launched 164 days ago and the Max4 launched 346 days ago. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The A2L lists at $469 and the Max4 at $1,049 — $580 apart, so the Max4 costs 124% more.
Per litre of build volume, that works out to $14 for the A2L versus $20 for the Max4 — the A2L is the better value per litre as well.
With both in sale windows until Dec 5, 2026, this is a good moment to buy either — compare the live sale prices before you decide.
This one is close on paper. If you will stick to materials both printers list (PLA, PETG, TPU and ABS), save the $580; if you want ASA, PA, PA-CF, PC and PPS-CF, the Max4's enclosure earns its premium.
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.
The Max4 offers the largest build volume in Qidi's lineup — enabling large functional parts, architectural models, and production batch runs that exceed Plus5 capacity.
The Max4's closed-loop XY adds positional feedback for improved accuracy at high speeds — a differentiating feature at this price tier that reduces dimensional errors on large prints.
Qidi's proven active chamber heating technology scaled to a 390×390 mm bed — critical for consistent ABS, ASA, PA-CF, and PPS-CF results across the full build plate.
