The Bambu Lab H2D (professional) and Qidi Tech Plus4 (prosumer) 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. Note that the Plus4 has been replaced by the Plus5 and is no longer sold new. Both are enclosed CoreXY printers with 4-slot multicolor and automatic calibration. The H2D costs $850 more and gets you a top speed of 1,000 mm/s (vs 600) and 40% more build volume; the Plus4 answers with 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.
Full details →This printer is no longer sold new. It has been replaced by the Qidi Tech Plus5.
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. Look for clearance deals — the Plus5 is the current model.

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The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the H2D is the safer buy right now — it has no release history pointing to a successor yet, while the Plus4 has already been replaced by the Plus5.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Plus4 lists at $699 and the H2D at $1,549 — $850 apart, so the H2D costs 122% more.
Per litre of build volume, that works out to $43 for the H2D versus $27 for the Plus4 — the Plus4 is the better value per litre as well.
Buy the H2D. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price. If the Plus4 appealed to you, the fair comparison today is the H2D against the Plus5.

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.
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
