Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2 Pro[1]QIDI X-Plus 3, listed in QIDI navigation as X-Plus3[2][3]
Release date (announcement and actual shipping)Not documentedNot published by QIDI on the pages checked (Aug 2026)[2][3]
Street price (USD; dated snapshot per entry)$599.00 and $799.00 are the two variant prices listed on the Creality US store K2 Pro Combo page, Aug 2026 - the combo includes a CFS unit, so neither figure is a bare-printer price[4]$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)Between the K2 (260 mm cube, no chamber heating, 100 C bed, 8 GB) and the K2 Plus (350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi). The K2 Pro shares the K2's 300 C nozzle and 70 W hotend but gets the chamber heater, RFID reader, Ethernet and 32 GB storage[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][5][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 x 300 x 300 mm[1]280 x 280 x 270 mm advertised[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)445 x 477 x 573 mm[1]511 x 527 x 529 mm[2]
Net weight (kg)23.7 kg[1]24.3 kg net[2]
Frame construction & materialNot documentedAll-metal frame per QIDI's US page; no further breakdown published[3]
Enclosure: open / enclosed; panel material; door/lidEnclosed with chamber temperature control up to 60 C; one air filter[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]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 documentedLinear optical axis of high-strength steel[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedDouble Z axis[2]
Belts (type, width, e.g. Gates?)Manual belt tensioning[1]Not documented
Stepper motors (frame size, step angle, brand if known)Step-servo motors on the X and Y axes and the extruder[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 documentedConflicting: 30 mm3/s (3DJake) vs 35 mm3/s (QIDI US page). Lower figure used[2][3]
Extruder
Type (direct drive / bowden) & design nameNot documentedHigh-flow direct-drive extruder, 1.75 mm filament[2][3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedCeramic 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 limit110 C max heatbed temperature[1]<=120 °C claimed[2][3]
Bed surface (material, texture, coating), single/double-sidedNot documentedDouble-sided flexible magnetic RF plate[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Smart auto levelling, plus automatic flow-rate calibration using a nozzle AI camera[1]Automatic bed levelling; probe technology not named[3]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament detection fitted; type and location not published[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designOne auxiliary cooling fan and one air filter[1]Not documented
Electronics & Power
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documentedCortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[2][3]
Input voltage (110/220 V, switch or auto)Not documented100-240 VAC, 50/60 Hz[2]
Total rated power drawNot documented800 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[7][8][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 and a built-in RFID reader for automatic filament identification (needs Creality RFID filament)[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi 2.4 GHz, RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[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 at 720p 30 fps, plus a separate nozzle AI camera used for flow calibration[1]Not documented
Materials Support
Officially supported filament listPLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, 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[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]1-year coverage (QIDI standard store terms)[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.
