The Q2 (prosumer) and Max4 (professional) are a step-up decision within Qidi Tech's lineup: same ecosystem, different class of machine. Both are enclosed CoreXY printers with 4-slot multicolor and automatic calibration. The Max4 costs $550 more and gets you 177% more build volume and a top speed of 800 mm/s (vs 600).
First-generation product — recently released, still early days
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.
Full details →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
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 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.
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 Max4 is the safer buy right now — it launched only 346 days ago, while the Q2 is late in its cycle (87% through).

The Q2 lists at $499 and the Max4 at $1,049 — $550 apart, so the Max4 costs 110% more.
Per litre of build volume, that works out to $20 for the Max4 versus $27 for the Q2 — so the pricier Max4 actually gives you more build space per dollar.
Our pick for most buyers is the Max4, for 177% more build volume and a top speed of 800 mm/s (vs 600), plus better buy-now timing. Go for the Q2 instead if you want to spend less — it is $550 cheaper ($499 vs $1,049).
How we judge timing and deals: read our methodology →
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.
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.
