| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K1 (store title "Creality K1 Speedy 3D Printer")[1][2] | Prusa CORE One+ (Gen 2). Prusa's e-shop lists "Prusa CORE One+ (Gen 2)" and "Prusa CORE One+ (Gen 2) Assembly kit"[3][4] |
| 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[5] |
| Street price (USD; dated snapshot per entry) | $299.00 on store.creality.com, Aug 2026. Creality's own K1-series comparison page shows $389 against a struck-through $599 on the same day[2][1] | $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[4][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Base model of the K1 family. The differences that matter are in the hotend: the K1 uses a metal + PTFE-tube hotend with a copper nozzle, while the K1C is all-metal with a steel-tipped nozzle integrated with the heatbreak and adds an air filter and a 1080p AI camera. Creality's own comparison table annotates the K1 hotend "Changing to All-metal Soon", so the hotend on a given unit depends on when it was built - check before buying. The K1 Max is the 300 mm version with 1000 W rated power and Ethernet; the K1 SE has a PA+30%GF hotend and an epoxy plate[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[3][4][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| Market position: superseded?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+[4] |
| 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)[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 480 mm[1] | 415 x 444 x 555 mm (X x Y x Z)[3] |
| Net weight (kg) | 12.5 kg (Tom's Hardware measurement)[8] | 22.5 kg[3] |
| Frame construction & material | Not documented | All-steel exoskeleton (Prusa's own comparison wording, against "aluminium extrusions and frame" for the MK4S)[9] |
| 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[1] | Fully enclosed with a door-open sensor and active chamber temperature control up to 55 C; HEPA/advanced filtration is an optional add-on[3][9] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active chamber heating, maximum 55 C (manufacturer figure)[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (Creality's own K1-series comparison table)[1] | CoreXY - stated as such in Prusa's own comparison table against the Cartesian MK4S[3] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 0.9 degree X and Y stepper motors[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic 2130[3] |
| 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[1][6] | 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[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct-drive extruder[1] | Nextruder direct drive, E3D V6 compatible with an adapter; planetary gear system with a 10:1 ratio; aluminium heatsink and all-metal hotend[3] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Metal hotend with a PTFE (Teflon) tube in the filament path and a copper nozzle. Creality's own comparison table adds "(Changing to All-metal Soon)", so this is a moving target across production runs[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[3] |
| 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[3][5] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature[1] | 120 C max heatbed temperature[3] |
| Bed surface (material, texture, coating), single/double-sided | Coated steel flex plate, heated, removable[8] | Magnetic heatbed with removable PEI spring-steel sheets; whole-bed heating regardless of object size[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic bed levelling (Tom's Hardware); unlike the K1 Max there is no lidar[8][10] | Load-cell sensor - fully automatic first-layer calibration with the nozzle as the probe[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted[8] | Two filament sensors, plus a door sensor and five Semitec thermistors with fan RPM monitoring[3][9] |
| 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[3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Closed-loop part-cooling fan; PWM hotend cooling fan[1] | High-performance turbine part-cooling fan with 360-degree cooling, the same arrangement as the MK4S[3] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy board with STM32[3] |
| PSU (brand, wattage, rail voltage) | Not documented | 240 W PSU with hardware power panic[3] |
| Total rated power draw | 350 W rated power[1] | Power consumption 90 W printing PLA, 110 W printing ABS (manufacturer figures)[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Creality OS, a Klipper derivative. Creality publishes the source as CrealityOfficial/K1_Series_Klipper on GitHub, whose own description is "clone from https://github.com/Klipper3d/klipper/", GPL-3.0, last pushed December 2025[11][12][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[13][9] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch 800x480 colour touchscreen[1] | 3.5-inch 65k-colour graphic screen with touch control[3] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; remote monitoring, time-lapse, failure detection and build-surface detection are all optional on the K1 because they depend on the optional AI camera[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[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi only - no Ethernet (the K1 Max adds RJ45); 8 GB of on-board storage[1] | Ethernet and Wi-Fi (NFC receiver plus an optional Wi-Fi module), USB drive for print files[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera optional, not fitted as standard - unlike the K1C and K1 Max, which include a 1080p camera[1] | Optional in-chamber camera solution (Buddy3D camera bundle listed at $1,237.03 against $1,202.78 for the bare printer)[3][4] |
| Materials Support | ||
| Officially supported filament list | Hyper PLA, PLA, PETG, TPU, ABS - a notably shorter list than the K1C, because of the PTFE-lined hotend[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and - as advanced materials in the heated chamber - ABS, ASA, HIPS and PA[3] |
| 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[11][12] | The xBuddy platform carries hardware overcurrent protection that cuts heater and heatbed power above 15 A, and the firmware is open-source and auditable[14][13] |
| 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[2] | 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[15][9] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware rating 4 out of 5 in the page's structured data - the lowest of the K1 family, where the K1C and K1 Max both score 4.5[8][10][16] | 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.
