| Property | Creality K2COREXY | QIDI X-Plus 3COREXY |
|---|---|---|
| Identity | ||
| Brand | Creality | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2[1] | QIDI X-Plus 3, listed in QIDI navigation as X-Plus3[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published by QIDI on the pages checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $699 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026. 3DJake lists the model as sold out[3][2] |
| 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] | Two headline-speed figures circulate for this model: QIDI's own US page says 600 mm/s and 35 mm3/s, 3DJake's spec table says <=500 mm/s and 30 mm3/s. This is exactly the kind of sibling contamination the 3-series suffers (X-Max 3 is 600 mm/s / 35 mm3/s). Siblings: X-Max 3 (325x325x315, 900 W) and X-Smart 3 (175x180x170, no chamber heat, 300 °C)[2][3][4][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 280 x 280 x 270 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 404 x 436 x 545 mm[1] | 511 x 527 x 529 mm[2] |
| Net weight (kg) | 18.3 kg[1] | 24.3 kg net[2] |
| Frame construction & material | Not documented | All-metal frame per QIDI's US page; no further breakdown published[3] |
| 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] | Fully enclosed with a heated chamber[2][3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, independent chamber heating (manufacturer claim)[2][3] |
| 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[2] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear optical axis of high-strength steel[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Double Z axis[2] |
| 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] | Conflicting manufacturer claims: QIDI's US page says 600 mm/s, 3DJake's spec table says <=500 mm/s. The lower, more conservative figure is used as the sortable value[2][3] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | 20,000 mm/s2 (manufacturer claim)[3] |
| Max volumetric flow claimed (mm³/s) | Not documented | Conflicting: 30 mm3/s (3DJake) vs 35 mm3/s (QIDI US page). Lower figure used[2][3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | High-flow direct-drive extruder, 1.75 mm filament[2][3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heating core. Copper-alloy nozzle head for normal materials, hardened-steel nozzle head for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | <=350 °C claimed[2][3] |
| Heater cartridge power (W) | 70 W rated hotend power[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature - the lowest in the K2 family[1] | <=120 °C claimed[2][3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided flexible magnetic RF plate[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] | Automatic bed levelling; probe technology not named[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament detection fitted; type and location not published[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One auxiliary cooling fan and one air filter[1] | Not documented |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[2][3] |
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 50/60 Hz[2] |
| Total rated power draw | Not documented | 800 W rated[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] | Klipper[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4-inch touchscreen[1] | 5-inch touchscreen, 800 x 480[2] |
| 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] | Wi-Fi (150M 2.4G), Ethernet, USB flash drive[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 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] | Not documented |
| 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] | 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[8] | 1-year coverage (QIDI standard store terms)[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.
