The Plus5 (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 $300 more and gets you 68% 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.

Best for: Makers and small businesses who need a large enclosed build volume for engineering materials at a prosumer price — particularly those printing PA-CF, ABS, and PC at scale.

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 Plus5 was released on Aug 5, 2026, 99 days ago. Its previous release cycle ran about 684 days, so it is 14% of the way through — roughly 585 days before a successor would be due at that pace.
Both are early enough in their cycles that timing should not decide this one. The Max4 launched 346 days ago and the Plus5 has roughly 585 days of runway on past cadence. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Plus5 lists at $749 and the Max4 at $1,049 — $300 apart, so the Max4 costs 40% more.
Per litre of build volume, that works out to $20 for the Max4 versus $24 for the Plus5 — so the pricier Max4 actually gives you more build space per dollar.
Our pick for most buyers is the Plus5, for a lower price ($300 less), plus a higher editor score (8.4 vs 8.2). Go for the Max4 instead if you print large parts — its 390 × 390 × 340 mm build volume holds 68% more than the Plus5's 320 × 320 × 300 mm.
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.
An 18% larger build volume than the Plus4's 305×305×280 mm, in the same enclosed prosumer class.
A 550 W third-generation chamber heater holds 65°C for PA, PA-CF, ABS, ASA, and PC with minimal warping across the build plate.
Handles high-performance engineering composites including carbon- and glass-fiber reinforced filaments and PPS-CF without a separate hotend upgrade.
