The Bambu Lab X2D and Qidi Tech Max4 are both professional-tier printers, but the Max4 costs 1.6× as much — so the question is what the extra money buys. Both are enclosed CoreXY printers with 4-slot multicolor and automatic calibration. The Max4 costs $400 more and gets you 203% more build volume and extra engineering materials (PPS-CF); the X2D answers with a top speed of 1,000 mm/s (vs 800) and support for PETG-CF.
Just released — full support runway ahead
Best for: Professional makers who want the X1C's footprint with true dual-material capability, an active heated chamber for engineering filaments, and improved filtration — without stepping up to the larger, pricier H2 series.

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 X2D was released on Apr 14, 2026, 212 days ago. Its previous release cycle ran about 1,359 days, so it is 16% of the way through — roughly 1,147 days before a successor would be due at that pace.
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 X2D has roughly 1,147 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 X2D lists at $649 and the Max4 at $1,049 — $400 apart, so the Max4 costs 62% more.
Per litre of build volume, that works out to $38 for the X2D 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 X2D, for a lower price ($400 less) and a top speed of 1,000 mm/s (vs 800), plus a higher editor score (9.1 vs 8.2). Go for the Max4 instead if you print large parts — its 390 × 390 × 340 mm build volume holds 203% more than the X2D's 256 × 256 × 260 mm.
How we judge timing and deals: read our methodology →
A second Bowden-fed nozzle enables two-material prints and soluble supports without a purge tower, in the same compact 256 mm class as the X1C it replaces.
Unlike the X1C's passive chamber warming, the X2D actively heats to 65°C — enough for the bulk of engineering filaments including ABS, ASA, and nylon.
Improved filtration and a toolhead-mounted camera add safety and monitoring over the X1C's chamber camera.
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.
