| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1[1] | Anycubic Kobra S1 Max[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3] | Listed on the Anycubic store from 16 January 2026 (Shopify publish date)[4] |
| 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] | $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)[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][2] | 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[2][1] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 250 mm[1] | 350 x 350 x 350 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 400 x 410 x 490 mm[1] | 502.7 x 483 x 584 mm[2] |
| Net weight (kg) | 9.37 kg net, 20.2 kg packaged[1] | 25.7 kg net, 31 kg packaged[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][2] | 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[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 C active chamber heating (manufacturer figure, actively heated rather than passive)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | CoreXY (stated outright in Anycubic's specification table)[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[2] |
| Recommended/typical print speed | 300 mm/s recommended print speed (manufacturer figure)[1] | 300 mm/s recommended print speed (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1] | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | Direct drive ("short distance extrusion") with hardened-steel extruder gears, which Anycubic rates at six times the life of brass on carbon-fibre filament[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] | 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[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 C maximum nozzle temperature[1] | 350 C maximum 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 maximum hotbed temperature on a PEI spring steel build plate[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] | LeviQ 3.0 auto-levelling[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection and power-loss resume[1] | Filament detection with auto resume, entanglement detection and power-loss resume[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] | Up to 16-colour printing with ACE 2 Pro units, sold separately[2] |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | Activated carbon filter for odour removal; dual external-circulation cooling fans[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS, with pressure advance and flow calibration supported[1] | Kobra OS with pressure advance and flow calibration supported[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 4.3-inch capacitive touchscreen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus slicing software, the Anycubic app and USB (print only); AI spaghetti detection and object-skip supported[1] | Touchscreen plus slicing software, Anycubic app and U-disk; AI spaghetti detection using an in-house algorithm and the 720p camera[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app, USB (print only)[1] | Printer UI, slicing software, Anycubic app and U-disk[2] |
| 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][2][5] | Standard HD camera, 720p, used for real-time AI anomaly detection[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Ships 95% pre-assembled; Anycubic claims unbox to print in 10 minutes[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] | 48 dB or less in standard mode, as low as 45 dB in quiet mode - manufacturer figures with no distance or method stated[2] |
| 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[6] | 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.

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.
