| Property | Creality K2 PlusCOREXY | QIDI i-FastIDEX |
|---|---|---|
| Identity | ||
| Brand | Creality | QIDI |
| Class | COREXY | IDEX |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2 Plus[1] | QIDI Tech i-Fast, also written iFast and "I-Fast"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on the listings checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | $999.00 on store.creality.com, Aug 2026[4] | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Largest and only fully specified K2. It is the only one with a 350 C nozzle, a 120 C bed, 30000 mm/s2 acceleration, step-servo motors on Z as well as X/Y, automatically adjusted belt tension, two auxiliary cooling fans, two air filters, a 1080p chamber camera, dual-band Wi-Fi and a 4.3-inch screen. Its "smart auto levelling" is listed as arriving via firmware update rather than shipping enabled, unlike the K2 and K2 Pro. A separate K2 SE model also exists[1] | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[3][2] |
| Market position: superseded? successor announced? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[3][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 350 x 350 x 350 mm[1] | 330 x 250 x 320 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 495 x 515 x 640 mm[1] | 710 x 510 x 670 mm[3] |
| Net weight (kg) | 35 kg[1] | 33 kg net[3] |
| Frame construction & material | Not documented | Fully assembled enclosed metal-frame machine[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with chamber temperature control up to 60 C and two air filters[1] | Fully enclosed with a heated chamber[2][3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 60 C max chamber temperature (manufacturer figure)[1] | Not documented |
| 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] | Dual independent extruders in an enclosed Cartesian gantry[2][3] |
| Belts (type, width, e.g. Gates?) | Automatically adjusted belt tension - the K2 and K2 Pro are tensioned by hand[1] | Not documented |
| Stepper motors (frame size, step angle, brand if known) | Step-servo motors on the X, Y and Z axes and the extruder[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s max printing speed (manufacturer claim)[1] | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[3] |
| Max acceleration (claimed, mm/s²) | 30000 mm/s2 max acceleration (manufacturer claim) - 50% above the rest of the K2 family[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with a 0.4 mm hardened "unicorn" quick-swap nozzle[6] | Direct-drive, two extruders. MK10-style nozzle[2][3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature[1] | 350 °C on the high-temperature extruder assembly[2][3] |
| Heater cartridge power (W) | 100 W rated hotend power[1] | Not documented |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm nozzle diameter[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Coated steel flex plate, heated, removable[6] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Smart auto levelling listed as "Available via Firmware Update" rather than shipping enabled; automatic flow-rate calibration via the nozzle AI camera[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted[6] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Two auxiliary cooling fans and two air filters[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 110-220 V[3] |
| Total rated power draw | Not documented | 700 W rated[3] |
| 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 documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch touchscreen[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touch UI with a built-in RFID reader; Creality notes the K2 Plus has no alarm sounds, which the K2 and K2 Pro do have[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi (2.4 and 5 GHz), RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[1] | Wi-Fi, LAN, USB flash drive[2][3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | One chamber camera at 1080p 30 fps plus the nozzle AI camera[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, PPA-CF[1] | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[3] |
| 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 |
| Independently Measured Performance | ||
| Benchmark print times (source + settings) | Benchy in 15 minutes 56 seconds - independently measured by Tom's Hardware, which noted visible layer lines and slightly droopy overhangs at that speed[6] | Not documented |
| Review scores from major outlets (list outlet + score + date) | Tom's Hardware rating 4.5 out of 5 in the page's structured data[6] | 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.
