|---|---|---|
| Identity | ||
| Brand | Creality | FlashForge |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2[1] | Flashforge AD5X, sold as "AD5X - Multicolor 3D Printer for High-Speed, Full-Color Printing"[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $399.00 sale against a $549.00 compare-at price on flashforge.com, in stock, with a further $50 off at checkout, checked Aug 2026. A refurbished AD5X is listed at $315.00[2][3] |
| 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] | Shares the 220 mm Adventurer chassis with the 5M and 5M Pro but differs on the points that matter: 300 °C nozzle (vs 280 °C), 4-colour IFS unit, NO air filtration, NO auto shutdown, and a 300 mm/s print speed against a 600 mm/s travel speed. 3DJake and eolasprints both describe it as open-frame[2][4][5][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 220 x 220 x 220 mm advertised[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 404 x 436 x 545 mm[1] | Not documented |
| Net weight (kg) | 18.3 kg[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed, 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] | Open frame, no enclosure and no air filtration — FlashForge's own table records "Air Filtration: No". Chamber lighting and remote monitoring are listed as expandable options rather than fitted[2][5] |
| 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[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 |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s max printing speed (manufacturer claim)[1] | FlashForge publishes two separate figures: max travel speed 600 mm/s and max print speed 300 mm/s. The 300 mm/s print figure is the one that describes printing[2][4] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | 20,000 mm/s2 maximum (manufacturer claim)[2][4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Direct drive, one extruder, fed by the 4-colour Intelligent Filament System (IFS)[2] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 300 °C claimed[2][4] |
| Heater cartridge power (W) | 70 W rated hotend power[1] | Not documented |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm default; 0.25, 0.6 and 0.8 mm optional[2][4] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature - the lowest in the K2 family[1] | 110 °C claimed[2][4] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | PEI flexible spring-steel sheet[2][4] |
| 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] | Automatic levelling; probe technology not named[2][4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament detection fitted; type and location not published[2][4] |
| Multi-material/multi-color capability or official upgrade path | Not documented | Four-colour printing via the integrated Intelligent Filament System (IFS), which handles filament switching[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One auxiliary cooling fan and one air filter[1] | Not documented |
| 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[7][8][1] | Not named by FlashForge; the supported slicers are Orca-Flashforge and OrcaSlicer[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4-inch touchscreen[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touch UI with alarm sounds; no built-in RFID reader[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[1] | USB, Ethernet, Wi-Fi[2][4] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | One chamber camera, 720p at 30 fps[1] | Not documented |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-outage recovery supported; mechanism not published[2][4] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and PPA-CF[1] | PETG, PLA, TPU95A, TPU64D-75D, PLA-CF, PETG-CF[2][4] |
| 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[7][8] | Not documented |
| 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[9] | 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.
