| Property | Bambu Lab H2SCOREXY | ELEGOO Centauri CarbonCOREXY |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | ELEGOO |
| Class | COREXY | COREXY |
| 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] |
| Release date (announcement and actual shipping) | Not documented | Listed on the ELEGOO US store from 17 February 2025 (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] | $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) | 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H2D in the same 492x514x626 mm shell: 30 kg vs 31 kg, 340x320x340 mm single-nozzle volume vs 325x320x325 mm[1][5] | Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds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[6][7][2] |
| Market position: superseded? successor announced? | Not documented | Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji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[8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 340 x 320 x 340 mm (manufacturer figure)[1] | 256 x 256 x 256 mm; printing platform 260 x 260 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 492 x 514 x 626 mm - the same body as the H2D and H2C[1] | 398 x 404 x 490 mm[2] |
| Net weight (kg) | 30 kg net[1] | 17.5 kg net, 21 kg gross[2] |
| Frame construction & material | Aluminium and steel chassis and shell[1] | Integrated die-cast aluminium construction, which ELEGOO credits for reduced vibration at speed[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a door sensor; active chamber heating to 65 C, chamber exhaust and heat-circulation fans, G3 + H12 + coconut-shell carbon filtration[1] | Fully enclosed with a tempered glass door and top cover; a nano mineral crystal air filter, an auxiliary part-cooling fan and a chamber temperature regulator fan are fitted[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active chamber heating, maximum 65 C (manufacturer figure)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - not named in the spec sheet; grouped by Bambu with the H2 enclosed CoreXY machines at 20000 mm/s2[1] | CoreXY[2] |

| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | "Silent Drive (All Axes)" is all that is published; no driver part number is given[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 1000 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 500 mm/s or less, with 250 mm/s given by ELEGOO as the recommended speed[2] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[2] |
| Max volumetric flow claimed (mm³/s) | 40 mm3/s standard-flow hotend, 65 mm3/s optional high-flow hotend; Bambu's test is a 250 mm round single-wall model in Bambu ABS at 280 C[1] | 32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened-steel gears and a Bambu high-precision permanent-magnet synchronous extruder motor; built-in filament cutter[1] | Dual-gear direct extruder with one fan[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal hotend, hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; optional high-flow hotend[1] | Brass-hardened steel nozzle, 0.4 mm, with a titanium-alloy heat break; a heatbed nozzle wiper cleans it before each print[2] |

| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[1] | Filament run-out sensor, auto filament unloading, power-loss recovery and fan self-check; no clog detection on this model (the Centauri Carbon 2 adds it)[2][6] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan, hotend cooling fan, main control board fan, chamber exhaust fan, chamber heat-circulation fan and auxiliary part-cooling fan, all closed-loop controlled[1] | Part cooling plus an auxiliary part-cooling fan and a chamber temperature regulator fan, with real-time fan self-checks[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | ELEGOO describes it only as a "Powerful Self-Developed Motherboard"; no board model or MCU is published[2] |
| Total rated power draw | 100-120 VAC / 200-240 VAC 50/60 Hz; 2050 W at 220 V, 1170 W at 110 V[1] | 1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[9] | ELEGOO OS with OTA updates; 8 GB of on-board storage. ElegooSlicer recommended, with Orca and Cura supported[2] |
| Connectivity, UI & Camera | ||

| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Live-view camera 1920x1080 and toolhead camera 1600x1200; the 3264x2448 BirdsEye camera is fitted only on the Laser Edition[1] | Chamber camera fitted, with real-time monitoring and time-lapse; dual built-in LED strips[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA, PET, PPS, plus carbon/glass-fibre reinforced PLA, PETG, PA, PET, PC, ABS, ASA, PPA and PPS[1] | Carbon/glass fibre reinforced filaments, PLA, PETG, ABS, ASA, TPU, PET, PC, PA[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Operating 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[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.
