The Bambu Lab P2S (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. Both are enclosed CoreXY printers with 4-slot multicolor and automatic calibration. The Max4 costs $500 more and gets you 208% more build volume and a top speed of 800 mm/s (vs 600).
Early in release cycle — no urgency to wait
Best for: Serious makers and prosumers who need enclosed printing for ABS, ASA, PA, PA-CF, and PC — and want Bambu's plug-and-play experience at a prosumer price.

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 P2S was released on Oct 14, 2025, 394 days ago. Based on Bambu Lab's release cadence, we expect the next model (P3S or next prosumer model) around late 2027 — about 323 days away, which puts the P2S 55% of the way through its cycle.
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 P2S has roughly 323 days of runway on past cadence 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 P2S lists at $549 and the Max4 at $1,049 — $500 apart, so the Max4 costs 91% more.
Per litre of build volume, that works out to $33 for the P2S versus $20 for the Max4 — so the pricier Max4 actually gives you more build space per dollar.
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.
Our pick for most buyers is the P2S, for a lower price ($500 less), plus a higher editor score (9.2 vs 8.2). Go for the Max4 instead if you print large parts — its 390 × 390 × 340 mm build volume holds 208% more than the P2S's 256 × 256 × 256 mm.
How we judge timing and deals: read our methodology →
The P2S enclosure maintains a more consistent chamber temperature over the P1S, reducing warping on long ABS and PA prints.
PLA through PC — the P2S handles the entire engineering filament spectrum with reliable results.
The P-series CoreXY enclosure design strikes the best balance of price, speed, and material capability in Bambu's lineup.
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.
