| Brand | Bambu Lab | ELEGOO |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab X1-Carbon (X1C); spec PDF header "Bambu Lab X1-Carbon - Technical Specifications"[1] | ELEGOO Centauri Carbon 2 Combo[2] |
| Release date (announcement and actual shipping) | Announced 23 May 2022; Kickstarter pre-orders opened 31 May 2022 and ran to 30 June 2022, with shipment stated to start immediately after the campaign closed in July 2022[3] | Listed on the ELEGOO US store from 9 August 2026 (Shopify publish date)[4] |
| Launch MSRP (USD) | $1199 MSRP for the X1-Carbon, $1449 for the X1-Carbon Combo (with AMS); Kickstarter early-bird was $849 / $999. The non-carbon X1 was $999 MSRP[3] | Not documented |
| Street price (USD; dated snapshot per entry) | Not documented | $399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Three related SKUs at launch: X1 (steel nozzle, no carbon rails, $999), X1-Carbon ($1199) and X1-Carbon Combo (X1C + AMS, $1449). The X1E is a separate business-focused machine, not a trim level: it adds active chamber heating to 60 C, Ethernet with 802.1X, a HEPA/carbon filter stack, a 320 C hot end and a Smooth PEI plate, and weighs 16 kg against the X1C's 14.13 kg[3][5][1] | 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] |
| Market position: superseded? successor announced? | Discontinued. In Aug 2026 the X1-Carbon is absent from the Bambu Lab US store 3D-printer collection, /products/x1-carbon redirects to that collection, and the regional stores (EU, Asia, AU, CA) redirect to the same place; only X1-series spare parts remain in the store sitemap. Its market slot is now held by the X2D. No live first-party price could be recorded[9] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm advertised (manufacturer figure)[1] | 256 x 256 x 256 mm; printing platform 260 x 260 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 389 x 389 x 457 mm[1] | 500 x 480 x 743 mm with the CANVAS unit fitted[2] |
| Net weight (kg) | 14.13 kg net[1] | 19.35 kg net, 23.8 kg gross[2] |
| Frame construction & material | Welded steel chassis with an aluminium and glass shell - Bambu's launch release contrasts the welded chassis with the bolted frames of most consumer machines[1][3] | Integrated die-cast aluminium construction (Centauri Carbon platform)[7] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed, aluminium and glass, with a door sensor and an activated-carbon air filter. No active chamber heating (that is the X1E's addition)[1][5] | Fully enclosed; the Centauri Carbon 2 uses a HEPA plus granulated coconut-shell activated-carbon filter stack rather than the first generation's nano mineral crystal filter, and adds a smart exhaust grille[6][7] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY driven by two stepper motors with one belt each; Tom's Hardware confirms the XY gantry is fixed in Z and the platform drops during printing[10][11] | CoreXY[2] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Carbon-fibre X rail - Bambu's launch release calls it a "featherlight full-carbon X rail" and credits it for the 20000 mm/s2 acceleration figure; Tom's Hardware describes carbon-fibre rails on the X axis[3][11] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three leadscrews driven from a single stepper motor through a belt, moving the whole bed in Z; three manual levelling knobs under the bed, no motorised Z-tilt[10][11] | Three lead screws with three linear guide rods[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not published; no teardown source found that names the driver part[1] | "Silent Drive (All Axes)"; no driver part number published[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1] | 500 mm/s or less, with 250 mm/s given 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) | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1] | 20000 mm/s2 maximum acceleration; default 10000 mm/s2[2] |
| Max volumetric flow claimed (mm³/s) | 32 mm3/s claimed, measured by Bambu on a 150x150 mm single-wall model in Bambu ABS at 280 C[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened-steel extruder gears; the service part is the "Hardened Steel Extruder Unit (X1 series)"[1] | Dual-gear direct extruder with one fan[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal all-in-one hotend - nozzle integrated into the heatblock, joined to the heatsink by a thin metal tube, replaced as a unit. Hardened-steel nozzle as standard, 0.4 mm included, 0.2/0.6/0.8 mm optional[1][10] | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max hot-end temperature[1] | 350 C claimed max nozzle temperature - 30 C above the first-generation Centauri Carbon[2][7] |
| Heater cartridge power (W) | Not published. Bambu's own X1-series troubleshooting page states the ceramic heater measures about 12 ohm at room temperature, which at the 24 V rail works out to roughly 48 W - a derived figure, not a manufacturer rating[12] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C at 220 V, 120 C at 110 V max build-plate temperature (Bambu's spec sheet gives both; the wiki text quotes 110 C)[1][10] | 110 C max heated bed temperature at 25 C ambient[2] |
| Bed surface (material, texture, coating), single/double-sided | Flexible steel plate; Cool Plate and Engineering Plate included, High Temperature Plate optional[1] | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Nozzle-touch probing on three ceramic force (piezo) sensors under the heatbed, plus a separate toolhead micro-lidar (advertised 7 um resolution) used for first-layer inspection and flow calibration rather than for bed mesh[13][11][1] | 121-point auto-levelling with full-auto calibration[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Yes - filament run-out sensor and door sensor; filament odometry only with an AMS fitted[1] | Filament run-out sensor, clog detection, auto filament unloading and power-loss recovery[2] |
| Multi-material/multi-color capability or official upgrade path | Not documented | CANVAS multi-material capability included - the defining difference from the bare Centauri Carbon 2[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part-cooling fan, hot-end fan, control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan, all closed-loop controlled[1] | Not documented |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Chamber temperature regulator fan plus an activated-carbon filter[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Motion controller dual-core Cortex-M4; application processor quad ARM A7 at 1.2 GHz with a 2 TOPS NPU; 4 GB eMMC. Board model and chip markings not published[1] | "Powerful Self-Developed Motherboard" is all ELEGOO publishes[2] |
| Total rated power draw | 100-240 VAC 50-60 Hz; 1000 W at 220 V, 350 W at 110 V[1] | 1100 W at 220 V, 350 W at 110 V rated; 24 V output[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[14] | ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch 1280x720 touchscreen[1] | 5-inch colour capacitive touch screen (the first-generation Centauri Carbon used a 4.3-inch panel)[2][7] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus Bambu Handy app and Bambu Studio; on-device job control and monitoring[1] | Colour touch UI; LED lighting fitted; STL, OBJ, 3MF and STEP input[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi 2.4 GHz (802.11 b/g/n) and Bambu-Bus; 4 GB eMMC plus a microSD card reader. No Ethernet - that is the X1E's addition[1][5] | USB and Wi-Fi[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Built-in 1920x1080 chamber monitoring camera[1] | Camera fitted[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, ABS, ASA, PET supported; PA and PC listed Ideal; carbon/glass-fibre reinforced polymers listed Ideal (the machine ships with a hardened-steel nozzle)[1] | Ideal: PLA, PETG, ABS, ASA. Capable: TPU, PC, PA, PET and fibre-reinforced filaments[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | A firmware over-temperature protection exists and is documented by Bambu: HMS_0300-0200-0001-0003 is raised when the heater runs at full power but fails to bring the nozzle to target within time, which Bambu describes as "a safety mechanism designed to prevent potential damage to the device or other risks in case of a temperature control failure". Firmware is closed-source, so the exact thresholds cannot be verified[12][14] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Operating 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[15] | 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[16] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware: Editor's Choice, rating 4.5 out of 5 in the page's structured data (12 February 2024)[11] | Not documented |
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.
