| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K1C (product page title "K1C Carbon 3D Printer")[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) | Not documented | 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[4] |
| Street price (USD; dated snapshot per entry) | $369.00 on store.creality.com, Aug 2026. Creality's comparison page shows $529 against a struck-through $559 on the same day[5][6] | $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) | The carbon-fibre-capable K1. Against the K1: all-metal hotend and a steel-tipped tri-metal "unicorn" nozzle integrated with the heatbreak instead of metal+PTFE and copper; air filter fitted instead of absent; 1080p AI camera, foreign-object detection, remote monitoring, time-lapse, build-surface detection and failure detection all standard instead of optional; a much longer filament list including PLA-CF, PA-CF and PET-CF. Build volume, footprint, speed and screen are identical to the K1, so a spec box that lists only those numbers cannot tell the two apart. A K1C Bayern Edition also exists[1][6] | 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| Market position: superseded?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? | Not documented | 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 usable | 220 x 220 x 250 mm[1] | 250 x 220 x 270 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 482 mm[1] | 415 x 444 x 555 mm (X x Y x Z)[2] |
| Net weight (kg) | 12.4 kg net, 16 kg gross[1] | 22.5 kg[2] |
| Frame construction & material | Not documented | All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[8] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with passive chamber heating only - Creality's comparison table lists "Passive Heating" for the K1, K1C and K1 Max and no chamber heating for the K1 SE[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][8] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active chamber heating, maximum 55 C (manufacturer figure)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (Creality's own K1-series comparison table)[6] | CoreXY - stated as such in Prusa's own comparison table against the Cartesian MK4S[2] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 0.9 degree X and Y stepper motors[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic 2130[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s max printing speed (manufacturer claim). Creality's own footnote says the 600 mm/s figure was achieved in Creality Lab and that the typical speed is 300 mm/s[6][1] | Not documented |
| Recommended/typical print speed | 300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[6] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[6] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct-drive extruder[6] | 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 material | Not documented | 10:1 planetary gearbox[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | All-metal hotend with a tri-metal "unicorn" quick-swap nozzle - a steel-tipped copper nozzle integrated with the heatbreak, replaced as a unit[1] | 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 nozzle 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][4] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature[1] | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | PEI flexible build plate[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) | Hands-free auto levelling[1] | Load-cell sensor - fully automatic first-layer calibration with the nozzle as the probe[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted; power-loss recovery[1] | Two filament sensors, plus a door sensor and five Semitec thermistors with fan RPM monitoring[2][8] |
| Multi-material/multi-color capability or official upgrade path | Not documented | MMU3 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 design | Dynamically balanced closed-loop part-cooling fan; dynamically balanced PWM hotend fan; activated-carbon air purifier fitted[1] | High-performance turbine part-cooling fan with 360-degree cooling, the same arrangement as the MK4S[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy board with STM32[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 240 W PSU with hardware power panic[2] |
| Total rated power draw | 350 W rated power; input 100-120 V / 200-240 V, 50/60 Hz[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) | Creality OS, a Klipper derivative - the K1-series firmware source is published as CrealityOfficial/K1_Series_Klipper on GitHub under GPL-3.0, described by Creality as a clone of upstream Klipper. Creality also lists the printhead front cover and side-mounted spool holder as open-source parts[9][10][6] | 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[11][8] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch 800x480 colour touchscreen[1] | 3.5-inch 65k-colour graphic screen with touch control[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI with sleep mode, lighting control and input shaping; remote monitoring, time-lapse and AI failure detection are included rather than optional[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-drive | Wi-Fi and USB drive; 8 GB on-board storage[1] | 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) | AI camera fitted as standard, 1080p, with foreign-object detection and failure detection[6] | 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 list | ABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[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) | Not verified directly. Creality's published firmware for the K1 series (CrealityOfficial/K1_Series_Klipper, GPL-3.0) is described by Creality itself as a clone of upstream Klipper, and upstream Klipper ships the verify_heater thermal-runaway check; whether Creality's stock printer.cfg enables it, and with what thresholds, was not checked here[9][10] | The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[12][11] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Creality's US store states "Up to 12-Month Warranty", a 14-day return and refund window and "Lifetime Customer Support" on its printer product pages. The "up to" wording means the term is not uniform across parts[13] | 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[14][8] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware rating 4.5 out of 5 in the page's structured data[15] | 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.
