The Bambu Lab H2S (professional) and Elegoo Centauri Carbon 2 (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 CoreXY printers with 4-slot multicolor and automatic calibration. The H2S costs $890 more and gets you an enclosed chamber (with PA, PA-CF, PC and PPS on its materials list) and 120% more build volume.
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: Elegoo users and budget-conscious makers who want multicolor FDM from a brand known for resin printers — or those looking for a capable CoreXY with high-temperature nozzle capability at $449.

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 Centauri Carbon 2 was released on Jan 26, 2026, 290 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
On timing alone, the Centauri Carbon 2 is the safer buy right now — it launched only 290 days ago, while the H2S is mid-cycle (61% through).
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Centauri Carbon 2 lists at $359 and the H2S at $1,249 — $890 apart, so the H2S costs 248% more.
Per litre of build volume, that works out to $34 for the H2S versus $21 for the Centauri Carbon 2 — the Centauri Carbon 2 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 an enclosed chamber (with PA, PA-CF, PC and PPS on its materials list) and 120% more build volume, plus a higher editor score (9.1 vs 8.4). Go for the Centauri Carbon 2 instead if you want to spend less — it is $890 cheaper ($359 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.
The Centauri Carbon 2 marks Elegoo's entry into multicolor FDM printing — bringing the brand's value-focused approach to a segment dominated by Bambu and Anycubic.
The high-temperature nozzle enables printing of PA, PA-CF, and PC on an open-frame CoreXY — a notable differentiator at this price point.
Elegoo's proprietary CANVAS system provides 4-color filament switching at a competitive all-in price of $449.
