| Property | Creality K1 SECOREXY | 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 SE[1] | Prusa CORE One L+[2] |
| 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[3] |
| Street price (USD; dated snapshot per entry) | Creality's K1-series comparison page lists $359 for the K1 SE (Aug 2026); it does not appear as its own product on the Creality US store printer sitemap, so no separate live store price could be recorded[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[4][5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The cheapest K1. It keeps the 220 mm cube volume, CoreXY frame and 600 mm/s claim but drops a lot: hotend body is PA+30%GF rather than all-metal, the build plate is epoxy rather than PEI, there is no air filter, no chamber heating entry at all in Creality's table, no foreign-object or failure detection, and the AI camera, remote monitoring and time-lapse are optional. Its filament list stops at Hyper PLA, PLA, PETG and TPU. It does get the steel-tipped nozzle integrated with the heatbreak and dynamically balanced fans, which the base K1 does not[1] | 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][5][4] |
| 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[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 482 mm[1] | 469 x 521 x 635 mm[2] |
| Net weight (kg) | Not documented | 21.9 kg (48.3 lb)[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed body, but Creality's comparison table leaves chamber heating blank for the K1 SE where the K1, K1C and K1 Max are listed as passive heating[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[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 (Creality's own K1-series comparison table)[1] | CoreXY - stated in Prusa's CORE One+ comparison table[5] |
| 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 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 |
| 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 | 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[2] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Hotend body in PA+30% glass fibre with a steel-tipped nozzle integrated with the heatbreak - not the all-metal assembly of the K1C[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) | 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[2][3] |
| 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 | Epoxy flexible build plate - different from the PEI plate on the K1C[1] | 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) | Not documented | 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) | Not documented | Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Dynamically balanced closed-loop part-cooling fan and dynamically balanced PWM hotend fan; no air filter[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 | 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)[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Open-source Creality OS, a Klipper derivative (CrealityOfficial/K1_Series_Klipper on GitHub, GPL-3.0)[7][8][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[9][10] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 3.5-inch 65k-colour touch screen (CORE One family)[5] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; remote monitoring and time-lapse are optional because they require the optional AI camera[1] | On-device touch UI with Prusa Connect and Prusa mobile app remote control[5] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi[1] | Ethernet, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[2] |
| Materials Support | ||
| Officially supported filament list | Hyper PLA, PLA, PETG, TPU only[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 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[7][8] | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[11][9] |
| 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[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][10] |
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.
