| Brand | Anycubic | Bambu Lab |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1 Max[1] | Bambu Lab X1-Carbon (X1C); spec PDF header "Bambu Lab X1-Carbon - Technical Specifications"[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 16 January 2026 (Shopify publish date)[3] | 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] |
| Launch MSRP (USD) | Not documented | $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] |
| Street price (USD; dated snapshot per entry) | $699.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $899.00 ($804.00 for the EU plug variant)[3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The large enclosed Anycubic. Against the Kobra S1: 350 mm cube against 250 (Anycubic claims 174% more volume), 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 lacks entirely, a titanium-alloy throat tube and hardened-steel extruder gears, an activated carbon filter, 720p camera against 480p, and 25.7 kg against 9.37 kg. Its engineering-filament list is correspondingly longer[1][5] | 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][2] |
| Market position: superseded? successor announced? | Not documented | 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[7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 350 x 350 x 350 mm[1] | 256 x 256 x 256 mm advertised (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 502.7 x 483 x 584 mm[1] | 389 x 389 x 457 mm[2] |
| Net weight (kg) | 25.7 kg net, 31 kg packaged[1] | 14.13 kg net[2] |
| Frame construction & material | Not documented | 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[2][4] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed CoreXY with 65 C active chamber heating, dual external-circulation cooling fans and an activated carbon filter, plus a temperature and moisture display[1] | 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)[2][6] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 65 C active chamber heating (manufacturer figure, actively heated rather than passive)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | 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[8][9] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | 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][9] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | 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[8][9] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Not published; no teardown source found that names the driver part[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | 500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[2] |
| Recommended/typical print speed | 300 mm/s recommended print speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1] | 20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[2] |
| Max volumetric flow claimed (mm³/s) | Not documented | 32 mm3/s claimed, measured by Bambu on a 150x150 mm single-wall model in Bambu ABS at 280 C[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion") with hardened-steel extruder gears, which Anycubic rates at six times the life of brass on carbon-fibre filament[1] | Direct drive with hardened-steel extruder gears; the service part is the "Hardened Steel Extruder Unit (X1 series)"[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-release hotend with a titanium-alloy throat tube; 0.4 mm and 0.6 mm nozzles supplied, 0.25 and 0.8 mm optional; hardened steel[1] | 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[2][8] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C maximum nozzle temperature[1] | 300 C claimed max hot-end temperature[2] |
| Heater cartridge power (W) | Not documented | 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[10] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C maximum hotbed temperature on a PEI spring steel build plate[1] | 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)[2][8] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Flexible steel plate; Cool Plate and Engineering Plate included, High Temperature Plate optional[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling[1] | 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[11][9][2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, entanglement detection and power-loss resume[1] | Yes - filament run-out sensor and door sensor; filament odometry only with an AMS fitted[2] |
| Multi-material/multi-color capability or official upgrade path | Up to 16-colour printing with ACE 2 Pro units, sold separately[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Part-cooling fan, hot-end fan, control-board fan, chamber temperature regulator fan and auxiliary part-cooling fan, all closed-loop controlled[2] |
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Activated carbon filter for odour removal; dual external-circulation cooling fans[1] | Chamber temperature regulator fan plus an activated-carbon filter[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | 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[2] |
| Total rated power draw | Not documented | 100-240 VAC 50-60 Hz; 1000 W at 220 V, 350 W at 110 V[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS with pressure advance and flow calibration supported[1] | 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[12] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 5-inch 1280x720 touchscreen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus slicing software, Anycubic app and U-disk; AI spaghetti detection using an in-house algorithm and the 720p camera[1] | Touchscreen plus Bambu Handy app and Bambu Studio; on-device job control and monitoring[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app and U-disk[1] | 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[2][6] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera, 720p, used for real-time AI anomaly detection[1] | Built-in 1920x1080 chamber monitoring camera[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Ships 95% pre-assembled; Anycubic claims unbox to print in 10 minutes[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Consumer grades: PLA, PETG, TPU (95A), TPU for ACE, PET, PLA-CF, PETG-CF, PVA. Engineering grades: ABS, ASA, PC, PA, PA6-CF, PC-CF/GF, PET-CF[1] | 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)[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | 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[10][12] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 48 dB or less in standard mode, as low as 45 dB in quiet mode - manufacturer figures with no distance or method stated[1] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[13] | 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[14] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Not documented | Tom's Hardware: Editor's Choice, rating 4.5 out of 5 in the page's structured data (12 February 2024)[9] |
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.
