| Property | Anycubic Kobra S1COREXY | Bambu Lab X2DCOREXY |
|---|---|---|
| Identity | ||
| Brand | Anycubic | Bambu Lab |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1[1] | Bambu Lab X2D; spec PDF header "X2D Spec"[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $349.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $549.00 ($401.00 for the EU plug variant)[3] | From $649.00 on the Bambu Lab US store, Aug 2026; the compare page shows the same $649 figure[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The CoreXY line, not to be confused with the gantry/bed-slinger Kobra 3, Kobra 4 and Kobra X. Within the S line the Kobra S1 Max is a much bigger machine: 350 mm cube against 250, a 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 does not have at all, and 25.7 kg against 9.37 kg. Multicolour is sold separately on both (ACE Pro / ACE 2 Pro)[1][5] | Dual-nozzle machine: a main hotend with a permanent-magnet synchronous extruder motor and an auxiliary hotend with a plain stepper motor, so the two nozzles are not equivalent. Bambu publishes four different build volumes depending on which nozzle is used, and a shorter list of materials for the auxiliary nozzle. Physical dimensions (392x406x478 mm) are shared with the P2S but the X2D is 16.25 kg against the P2S's 14.9 kg[2][6] |
| Market position: superseded? successor announced? | Not documented | Current model, launched into the slot vacated by the discontinued X1-Carbon[4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 250 mm[1] | Main nozzle 256 x 256 x 260 mm; auxiliary nozzle 235.5 x 256 x 256 mm; dual-nozzle printing 235.5 x 256 x 256 mm; total volume for two nozzles 256 x 256 x 260 mm. The sortable figure below is the main-nozzle volume[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 400 x 410 x 490 mm[1] | 392 x 406 x 478 mm[2] |
| Net weight (kg) | 9.37 kg net, 20.2 kg packaged[1] | 16.25 kg net[2] |
| Frame construction & material | Not documented | Plastic and steel chassis; plastic, glass and metal outer frame[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed - Anycubic's own wording is "Fully Enclosed CoreXY Construction". There is no active chamber heating on the S1 (that is the S1 Max's addition)[1][5] | Fully enclosed with a door sensor, active chamber heating to 65 C, and a G3 + H12 HEPA + granulated coconut-shell carbon filter stack with an external exhaust fan[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active chamber heating, maximum 65 C (manufacturer figure)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | CoreXY - not stated in the spec sheet; Bambu groups the X2D with its enclosed CoreXY machines and publishes the same 20000 mm/s2 acceleration figure[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | 1000 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 (manufacturer claims)[1] | 20000 mm/s2 max toolhead acceleration (manufacturer claim)[2] |
| Max volumetric flow claimed (mm³/s) | Not documented | 40 mm3/s, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | Two direct-drive extruders: main extruder with hardened-steel gears driven by a Bambu high-precision permanent-magnet synchronous motor, auxiliary extruder with hardened-steel gears driven by a stepper motor[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-release hotend; 0.4 mm standard nozzle expandable to 0.25, 0.6 and 0.8 mm[1] | Dual hardened-steel nozzles; 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported; built-in filament cutter[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 C maximum nozzle temperature[1] | 300 C claimed max nozzle temperature[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C maximum hotbed temperature on a PEI spring steel build plate - the highest bed ceiling of any Anycubic machine in this file except the S1 Max[1] | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Flexible steel plate, Textured PEI included; Smooth PEI, Cool Plate SuperTack and Engineering Plate supported[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling with Z-offset, plus area levelling[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection and power-loss resume[1] | Yes - run-out sensor, tangle sensor and door sensor; odometry with AMS[2] |
| Multi-material/multi-color capability or official upgrade path | Multicolour is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Part-cooling fan, hotend cooling fan, main control board fan, chamber heat-circulation fan, auxiliary part-cooling fan and external exhaust fan, all closed-loop controlled[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Motion controller dual-core Cortex-M4 plus single-core Cortex-M7; application processor quad-core ARM with a dedicated NPU (2 TOPS per the compare page)[2][7] |
| Total rated power draw | Not documented | High-voltage version 1600 W at 220 V, low-voltage version 1100 W at 110 V; steady state 250 W printing PLA and 550 W printing PC at 25 C ambient[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[8] |
| Connectivity, UI & Camera | ||

| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera fitted, but only 480p - lower than the 720p units on the S1 Max, Kobra 4 and Kobra X[1][5][9] | Two cameras: live-view 1920x1080 and a toolhead camera at 1600x1200[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, ABS, ASA[1] | Main hotend: PLA, PETG, ABS, ASA, TPU, support materials, PET, PA, PC, PVA and carbon/glass-fibre reinforced PLA, PETG, ABS, ASA, PA6, PAHT, PPA, PET. Auxiliary hotend drops PPA-CF/GF and excludes PLA Aero; PLA Silk, PETG-CF, ASA-CF, PA6-CF, TPU for AMS and PA/PET support material are flagged "print with caution" on the auxiliary nozzle[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 46 dB or less in standard mode and 44 dB or less in quiet mode - manufacturer figures with no distance or method stated, so not comparable with an independently measured reading[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[10] | 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[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.
