The Bambu Lab H2S (professional) and Qidi Tech Plus5 (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. Both are enclosed CoreXY printers with 4-slot multicolor and automatic calibration. The H2S costs $500 more and gets you a top speed of 1,000 mm/s (vs 600) and 20% more build volume; the Plus5 answers with extra engineering materials (PPS-CF).
Mid-cycle — watch for announcements before buying
Best for: Professional makers and studios who need Bambu's largest enclosed build volume for high-throughput production, engineering materials, and optional AMS multicolor — without the complexity of dual-nozzle printing.

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 H2S was released on Aug 26, 2025, 443 days ago. Its previous release cycle ran about 730 days, so it is 61% of the way through — roughly 287 days before a successor would be due at that pace.
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.
On timing alone, the Plus5 is the safer buy right now — it is only 14% of the way through its expected cycle, while the H2S is mid-cycle (61% through).
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Plus5 lists at $749 and the H2S at $1,249 — $500 apart, so the H2S costs 67% more.
Per litre of build volume, that works out to $34 for the H2S versus $24 for the Plus5 — the Plus5 is the better value per litre as well.
With both in sale windows until Dec 5, 2026, this is a good moment to buy either — compare the live sale prices before you decide.
Our pick for most buyers is the H2S, for a top speed of 1,000 mm/s (vs 600) and 20% more build volume, plus a higher editor score (9.1 vs 8.4). Go for the Plus5 instead if you want to spend less — it is $500 cheaper ($749 vs $1,249).

The H2S offers more than twice the print volume of the X2D. At 1000 mm/s it is also among Bambu's fastest printers, making it the top choice for high-throughput professional production.
The enclosed chamber with active heating handles the full engineering filament spectrum — ABS, ASA, PA, PA-CF, PC, and PPS — with consistent results across the full build plate.
The H2S supports up to 12 AMS units (4 AMS 2 Pro + 8 AMS HT), enabling 24-filament printing for large-format multicolor production.
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.
