| Property | Anycubic Kobra S1COREXY | Prusa CORE One L+COREXY |
|---|---|---|
| Identity | ||
| Brand | Anycubic | Prusa Research |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1[1] | Prusa CORE One L+[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3] | The CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[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] | $1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[5][6] |
| 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][7] | Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[2][6][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 250 mm[1] | 300 x 300 x 330 mm, which Prusa states as 29.7 litres[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 400 x 410 x 490 mm[1] | 469 x 521 x 635 mm[2] |
| Net weight (kg) | 9.37 kg net, 20.2 kg packaged[1] | 21.9 kg (48.3 lb)[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][7] | Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active convection chamber heating, maximum 60 C (manufacturer figure)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | CoreXY - stated in Prusa's CORE One+ comparison table[6] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | Not documented |
| 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] | Not documented |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input Shaper and Phase Stepping with an integrated accelerometer[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | Nextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[2] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[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] | Tool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 C maximum nozzle temperature[1] | 290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[2][4] |
| 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 | Magnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[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] | High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection and power-loss resume[1] | Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[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 |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy mainboard with an STM32 processor[2] |
| Total rated power draw | Not documented | Standby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS, with pressure advance and flow calibration supported[1] | 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[8][9] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 3.5-inch 65k-colour touch screen (CORE One family)[6] |
| 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] | On-device touch UI with Prusa Connect and Prusa mobile app remote control[6] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app, USB (print only)[1] | Ethernet, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[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][7][10] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, ABS, ASA[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and with Advanced Filtration also ABS, ASA, HIPS and PA[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[11][8] |
| 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[12] | 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[13][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.
