The Bambu Lab H2D and Qidi Tech Max4 are cross-brand rivals: both are professional-tier printers, listed $500 apart. Both are enclosed CoreXY printers with 4-slot multicolor and automatic calibration. The H2D costs $500 more and gets you a top speed of 1,000 mm/s (vs 800) and support for PETG-CF; the Max4 answers with 42% more build volume and extra engineering materials (PPS-CF).
First-generation product — no release history to base predictions on
Best for: Professional makers and small studios who need dual-material printing for engineering parts with soluble supports — or two-material prints with minimal purge waste.

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 H2D was released on Mar 25, 2025, 597 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.
On timing alone, the Max4 is the safer buy right now — it launched only 346 days ago, while the H2D has no release history pointing to a successor yet.

The Max4 lists at $1,049 and the H2D at $1,549 — $500 apart, so the H2D costs 48% more.
Per litre of build volume, that works out to $43 for the H2D versus $20 for the Max4 — the Max4 is both cheaper and roomier, so it wins on value outright.
With both in sale windows, this is a good moment to buy either — compare the live sale prices before you decide.
This one is close on paper. If cost matters more than print time, save the $500; if throughput matters, the H2D's 1,000 mm/s top speed earns its premium. The Max4 also brings 42% more build volume and extra engineering materials (PPS-CF).
How we judge timing and deals: read our methodology →
The H2D's toolhead carries two nozzles, each with its own material. Switching between them avoids most of the purge waste of single-nozzle filament changes and enables dual-material prints including PVA/PLA soluble support combinations.
350×320×325 mm gives more print area than the standard 256 mm Bambu models — suited for larger professional parts.
The H2D supports a wide range of engineering filaments including PA-CF, PETG-CF, and PC with its enclosed chamber.
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.
