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]Prusa CORE One+ (Gen 2). Prusa's e-shop lists "Prusa CORE One+ (Gen 2)" and "Prusa CORE One+ (Gen 2) Assembly kit"[2][3]
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[4]The CORE One+ (Gen 2) refresh was announced on 13 August 2026, on sale immediately, with the first assembled units shipping at once and kits, upgrade kits and individual parts rolling out over the following weeks. It succeeds the CORE One and CORE One+ on the same platform[5]
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[4]Not documented
Street price (USD; dated snapshot per entry)Not documented$1,202.78 assembled, $925.00 as an assembly kit, on prusa3d.com, Aug 2026. Bundles run to $1,301.85 with camera and advanced filtration. Prusa's own marketing table on the same page quotes "from $1,299" assembled, which does not match the live e-shop price[3][2]
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[4][6][1]Three generations share the CORE One name: the original CORE One, the CORE One+, and the CORE One+ (Gen 2), with paid upgrade kits between them (CORE One+ to CORE One+ (Gen 2), and an MK4S to CORE One+ (Gen 2) conversion kit). The specifications recorded here are those published on Prusa's current CORE One+ (Gen 2) page and should not be assumed to hold for a first-generation CORE One. The INDX 4-tool and 8-tool machines are variants of the same product page, and the CORE One L is a larger, separate machine[2][3][7]
Market position: superseded?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[8]Current model and Prusa's mainstream enclosed machine, above the MK4S and below the CORE One L+[3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm advertised (manufacturer figure)[1]250 x 220 x 270 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)389 x 389 x 457 mm[1]415 x 444 x 555 mm (X x Y x Z)[2]
Net weight (kg)14.13 kg net[1]22.5 kg[2]
Frame construction & materialWelded 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][4]All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[9]
Enclosure: open / enclosed; panel material; door/lidFully 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][6]Fully enclosed with a door-open sensor and active chamber temperature control up to 55 C; HEPA/advanced filtration is an optional add-on[2][9]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedActive chamber heating, maximum 55 C (manufacturer figure)[2]
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 - stated as such in Prusa's own comparison table against the Cartesian MK4S[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[4][11]Not documented
Z-axis: leadscrew count & type, sync mechanism, anti-backlashThree 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]Not documented
Stepper motors (frame size, step angle, brand if known)Not documented0.9 degree X and Y stepper motors[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not published; no teardown source found that names the driver part[1]Trinamic 2130[2]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[1]Not documented
Max acceleration (claimed, mm/s²)20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[1]Not documented
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 nameDirect drive with hardened-steel extruder gears; the service part is the "Hardened Steel Extruder Unit (X1 series)"[1]Nextruder direct drive, E3D V6 compatible with an adapter; planetary gear system with a 10:1 ratio; aluminium heatsink and all-metal hotend[2]
Gear ratio & drive gear materialNot documented10:1 planetary gearbox[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]Quick-swap nozzle system; high-flow Prusa brass CHT 0.4 mm nozzle supplied. An optional HT hotend raises the ceiling to 400 C[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max hot-end temperature[1]290 C claimed max nozzle temperature. Prusa's comparison table adds "400 C w/ HT" for the optional HT hotend, which its 13 August 2026 blog post says will only become available in September 2026 - so 400 C is a forthcoming option, not a shipping specification[2][5]
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 limit110 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]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedFlexible steel plate; Cool Plate and Engineering Plate included, High Temperature Plate optional[1]Magnetic heatbed with removable PEI spring-steel sheets; whole-bed heating regardless of object size[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]Load-cell sensor - fully automatic first-layer calibration with the nozzle as the probe[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]Two filament sensors, plus a door sensor and five Semitec thermistors with fan RPM monitoring[2][9]
Multi-material/multi-color capability or official upgrade pathNot documentedMMU3 for five filaments, or the INDX system for up to eight, both officially supported[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan, hot-end fan, control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan, all closed-loop controlled[1]High-performance turbine part-cooling fan with 360-degree cooling, the same arrangement as the MK4S[2]
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]Custom 32-bit xBuddy board with STM32[2]
PSU (brand, wattage, rail voltage)Not documented240 W PSU with hardware power panic[2]
Total rated power draw100-240 VAC 50-60 Hz; 1000 W at 220 V, 350 W at 110 V[1]Power consumption 90 W printing PLA, 110 W printing ABS (manufacturer figures)[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]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[15][9]
Connectivity, UI & Camera
Display: size, type, touch?5-inch 1280x720 touchscreen[1]3.5-inch 65k-colour graphic screen with touch control[2]
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]On-device touch UI; remote monitoring and printing through Prusa Connect and the Prusa mobile app; firmware updates from USB, Prusa Connect or the app[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-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][6]Ethernet and Wi-Fi (NFC receiver plus an optional Wi-Fi module), USB drive for print files[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Built-in 1920x1080 chamber monitoring camera[1]Optional in-chamber camera solution (Buddy3D camera bundle listed at $1,237.03 against $1,202.78 for the bare printer)[2][3]
Materials Support
Officially supported filament listPLA, 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]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and - as advanced materials in the heated chamber - ABS, ASA, HIPS and PA[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]The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[16][15]
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[17]2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[18][9]
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.
