The Bambu Lab H3C (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 Note that the Plus4 has been replaced by the Plus5 and is no longer sold new.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 automatic calibration. The H3C costs $1,800 more and gets you a top speed of 1,400 mm/s (vs 600) and 32% more build volume; the Plus4 answers with 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: 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 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The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the H3C is the safer buy right now — it launched only 9 days ago, while the Plus4 has already been replaced by the Plus5.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 H3C at $2,499 — $1,800 apart, so the H3C costs 258% more.
Per litre of build volume, that works out to $73 for the H3C versus $27 for the Plus4 — the Plus4 is the better value per litre as well.
Buy the H3C. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price.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 H3C against the Plus5.

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.
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.
