Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab H2C; spec sheet header "H2C Spec Sheet"[1]ELEGOO Centauri Carbon[2]
Release date (announcement and actual shipping)Not documentedListed on the ELEGOO US store from 17 February 2025 (Shopify publish date)[3]
Street price (USD; dated snapshot per entry)From $2,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $2,399.00; the compare page shows $2,399[4]$419.99 on us.elegoo.com, Aug 2026, with the compare-at price also $419.99 (no discount running)[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Dual-nozzle top model in the H2 family, in the same 492x514x626 mm body as the H2D and H2S. Distinguishing figures: 32.5 kg (vs 31 kg H2D, 30 kg H2S); single-nozzle volume 305x320x325 mm (vs 325x320x325 mm on the H2D); BirdsEye camera fitted as standard rather than only on a Laser Edition; laser safety window listed as equipped with the Laser Edition[1][5][6][7]Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds clog detection, a smart exhaust grille and part-cooling-fan drop detection. The non-carbon Centauri and Centauri 2 are open-frame-oriented machines with a different filament list. Machine size 398 x 404 x 490 mm is shared with the Centauri 2, so body dimensions alone will not identify the model[8][9][2]
Market position: superseded? successor announced?Not documentedSuperseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji collaboration edition[10]

Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating sound published as 55 dB or less - a manufacturer figure with no distance or method stated, so not comparable with an independently measured dB reading[2]
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[12]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[13]

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.
