The Bambu Lab H3C and Qidi Tech Max4 are both professional-tier printers, but the H3C costs 2.4× as much — so the question is what the extra money buys. Both are enclosed CoreXY printers with automatic calibration. The H3C costs $1,450 more and gets you a top speed of 1,400 mm/s (vs 800) and support for PET and PVA; the Max4 answers with 51% more build volume and extra engineering materials (ABS, ASA and PPS-CF).
First-generation product — recently released, still early days
Best for: Studios, engineers and power users who print many colours or materials per job, such as soluble supports, rigid-plus-TPU parts or CMYKW colour mixing, and want each material on its own dedicated tool rather than purging through a single nozzle.

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 H3C was released on Nov 3, 2026, 9 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 H3C launched 9 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 Max4 lists at $1,049 and the H3C at $2,499 — $1,450 apart, so the H3C costs 138% more.
Per litre of build volume, that works out to $73 for the H3C versus $20 for the Max4 — the Max4 is both cheaper and roomier, so it wins on value outright.
If you are buying before Dec 5, 2026, the active sale tips value toward the Max4.
This one is close on paper. If cost matters more than print time, save the $1,450; if throughput matters, the H3C's 1,400 mm/s top speed earns its premium. The Max4 also brings 51% more build volume and extra engineering materials (ABS, ASA and PPS-CF).
How we judge timing and deals: read our methodology →
Swaptek keeps nine tools docked, loaded and pre-heated, each with its own filament path and heater. Bambu quotes 6-second material switches and very small purge volumes per swap, so multi-material prints waste far less filament than single-nozzle AMS printing.
Each tool can carry a different nozzle size or material. That makes it possible to print a 0.2 mm detail section, a 0.4 mm structural part and a soft 75A TPU section in one job.
The AMS 3H stores and feeds filament inside a sealed unit, and a built-in dryer handles moisture-sensitive PA, PC and TPU. Older AMS units can connect for up to 24 spools.
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.
