| Property | Creality K1COREXY | Prusa CORE One L+COREXY |
|---|---|---|
| Identity | ||
| Brand | Creality | Prusa Research |
| 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 L+[3] |
| Release date (announcement and actual shipping) | Not documented | 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) | $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] | $1,850.93 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) | 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][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[3][6][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 220 x 220 x 250 mm[1] | 300 x 300 x 330 mm, which Prusa states as 29.7 litres[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 480 mm[1] | 469 x 521 x 635 mm[3] |
| Net weight (kg) | 12.5 kg (Tom's Hardware measurement)[8] | 21.9 kg (48.3 lb)[3] |
| 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 chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active convection chamber heating, maximum 60 C (manufacturer figure)[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (Creality's own K1-series comparison 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)[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][7] | 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 |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input Shaper and Phase Stepping with an integrated accelerometer[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct-drive extruder[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[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] | 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[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. 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[3][4] |
| 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 dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[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][9] | High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted[8] | Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Closed-loop part-cooling fan; PWM hotend cooling fan[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[3] |
| Total rated power draw | 350 W rated power[1] | Standby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (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[10][11][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[12][13] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch 800x480 colour touchscreen[1] | 3.5-inch 65k-colour touch screen (CORE One family)[6] |
| 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 with Prusa Connect and Prusa mobile app remote control[6] |
| 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, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[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] | Not documented |
| 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 with Advanced Filtration also 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[10][11] | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[14][12] |
| 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][13] |
| 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][9][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.
