Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab H2S; spec sheet header "H2S & H2S Laser Edition Spec Sheet"[1]ELEGOO Centauri Carbon 2 Combo[2]
Release date (announcement and actual shipping)Not documentedListed on the ELEGOO US store from 9 August 2026 (Shopify publish date)[3]
Street price (USD; dated snapshot per entry)From $1,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,249.00[4]$399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Single-nozzle machine sharing the H2 body. H2S and H2S Laser Edition are covered by one spec sheet: the Laser Edition adds laser safety windows, the air-assist pump and the 3264x2448 BirdsEye camera, and a plain H2S can be upgraded with a Laser Upgrade Kit. Against the dual-nozzle H2D in the same 492x514x626 mm shell: 30 kg vs 31 kg, 340x320x340 mm single-nozzle volume vs 325x320x325 mm[1][5]The Centauri Carbon 2 sold with the CANVAS multicolour unit. Every printing figure matches the bare Centauri Carbon 2; what changes is the body - 500 x 480 x 743 mm and 19.35 kg with CANVAS fitted - and CANVAS capability being listed Yes. Against the first-generation Centauri Carbon: 350 C nozzle rather than 320 C, clog detection added, and a HEPA plus coconut-shell carbon filter stack rather than the nano mineral crystal filter. An ELEGOO x emoji collaboration edition of the same machine is also listed[2][6][7][8]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable340 x 320 x 340 mm (manufacturer figure)[1]256 x 256 x 256 mm; printing platform 260 x 260 mm[2]

Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating sound published as 45 dB or less - a manufacturer figure with no distance or method stated, and 10 dB below the first-generation Centauri Carbon's published figure[2][7]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[10]12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[11]

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
