Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2[1]Prusa CORE One L+[2]
Release date (announcement and actual shipping)Not documentedThe 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)Not documented$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)Smallest of three K2 machines that share a product page. K2: 260 mm cube, no chamber heating, 100 C bed, 300 C nozzle, 8 GB storage, one air filter, one auxiliary cooling fan, 720p camera, no RFID reader, no Ethernet. K2 Pro: 300 mm cube, 60 C chamber, 110 C bed, RFID, Ethernet, 32 GB. K2 Plus: 350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual air filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi. A K2 SE also exists as a separate model[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 usable260 x 260 x 260 mm[1]300 x 300 x 330 mm, which Prusa states as 29.7 litres[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)404 x 436 x 545 mm[1]469 x 521 x 635 mm[2]
Net weight (kg)18.3 kg[1]21.9 kg (48.3 lb)[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed, but with no chamber temperature control - Creality's table gives a max chamber temperature for the K2 Pro and K2 Plus and a dash for the K2. One air filter fitted[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 documentedActive convection chamber heating, maximum 60 C (manufacturer figure)[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY - Creality groups the K2 series with its CoreXY flagships and quotes 600 mm/s with step-servo motors on the X and Y axes[1]CoreXY - stated in Prusa's CORE One+ comparison table[5]
Belts (type, width, e.g. Gates?)Manual belt tensioning (the K2 Plus is auto-adjusted)[1]Not documented
Stepper motors (frame size, step angle, brand if known)Step-servo motors on the X and Y axes and the extruder (the K2 Plus adds them on Z)[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 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)[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 documentedInput Shaper and Phase Stepping with an integrated accelerometer[2]
Extruder
Type (direct drive / bowden) & design nameNot documentedNextruder 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 materialNot documented10:1 planetary gearbox[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedTool-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]
Heater cartridge power (W)70 W rated hotend power[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature - the lowest in the K2 family[1]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedMagnetic 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)Smart auto levelling fitted; unlike the K2 Pro and Plus there is no nozzle AI camera, so there is no automatic flow-rate calibration[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)Not documentedTwo filament sensors, plus a chamber door-open sensor and five Semitec thermistors[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designOne auxiliary cooling fan and one air filter[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy mainboard with an STM32 processor[2]
Total rated power drawNot documentedStandby 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)Creality OS, a Klipper derivative. Creality publishes the K2 firmware source as CrealityOfficial/K2_Series_Klipper on GitHub under GPL-3.0, last pushed March 2026[6][7][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-inch touchscreen[1]3.5-inch 65k-colour touch screen (CORE One family)[5]
On-device UI capabilities (model preview, per-object controls, etc.)Touch UI with alarm sounds; no built-in RFID reader[1]On-device touch UI with Prusa Connect and Prusa mobile app remote control[5]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[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)One chamber camera, 720p at 30 fps[1]Not documented
Materials Support
Officially supported filament listPLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and PPA-CF[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 publishes the K2-series firmware as CrealityOfficial/K2_Series_Klipper (GPL-3.0); upstream Klipper ships the verify_heater thermal-runaway check, but whether the stock configuration enables it was not checked here[6][7]Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[10][8]
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[11]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[12][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.
