The Bambu Lab H2S (professional) and Qidi Tech Q1 Pro (entry) 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 Note that the Q1 Pro has been replaced by the Q2 and is no longer sold new. Both are enclosed CoreXY printers with automatic calibration. The H2S costs $750 more and gets you 157% more build volume and a top speed of 1,000 mm/s (vs 600).
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.
Full details →This printer is no longer sold new. It has been replaced by the Qidi Tech Q2.
Best for: Budget-conscious makers who need active chamber heating for ABS, ASA, and PA printing. Look for clearance deals — the Q2 is the better long-term buy if available.

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The Q1 Pro has been replaced by the Q2 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the H2S is the safer buy right now — it is mid-cycle (61% through), while the Q1 Pro has already been replaced by the Q2.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Q1 Pro lists at $499 and the H2S at $1,249 — $750 apart, so the H2S costs 150% more.
Per litre of build volume, that works out to $34 for the H2S versus $35 for the Q1 Pro — so the pricier H2S actually gives you more build space per dollar.
Buy the H2S. The Q1 Pro has already been replaced by the Q2 and is no longer sold new, so it is only worth considering at a clearance price. If the Q1 Pro appealed to you, the fair comparison today is the H2S against the Q2.

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.
The Q1 Pro's heated chamber was groundbreaking at its price point. ABS, ASA, and PA prints come out without warping that plagues open-frame printers.
Same speed class as Bambu Lab printers at a fraction of the price for enclosed printing.
