Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2 Plus[1]QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[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)$999.00 on store.creality.com, Aug 2026[4]$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[3]
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]Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[2][5][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable350 x 350 x 350 mm[1]175 x 180 x 170 mm advertised[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)495 x 515 x 640 mm[1]370 x 362 x 397 mm[2]
Net weight (kg)35 kg[1]10.5 kg[2]
Frame construction & materialNot documentedQIDI publishes no frame-material breakdown for this model[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed with chamber temperature control up to 60 C and two air filters[1]No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[2]
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]CoreXY[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]<=500 mm/s (manufacturer claim)[2][3]
Max acceleration (claimed, mm/s²)30000 mm/s2 max acceleration (manufacturer claim) - 50% above the rest of the K2 family[1]20,000 mm/s2 (manufacturer claim)[3]
Max volumetric flow claimed (mm³/s)Not documented30 mm3/s extruder flow (manufacturer claim)[2][3]
Extruder
Type (direct drive / bowden) & design nameDirect drive with a 0.4 mm hardened "unicorn" quick-swap nozzle[7]Direct-drive extruder, single, 1.75 mm filament[2][3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedBrass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)350 C claimed max nozzle temperature[1]<=300 °C claimed[2][3]
Heater cartridge power (W)100 W rated hotend power[1]Not documented
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedBrass[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]<=120 °C claimed[2][3]
Bed surface (material, texture, coating), single/double-sidedCoated steel flex plate, heated, removable[7]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 listed as "Available via Firmware Update" rather than shipping enabled; automatic flow-rate calibration via the nozzle AI camera[1]16-point automatic bed levelling per QIDI's US page; probe technology not named[3]
Mesh grid size (probe point count — firmware evidence)Not documented16 points (QIDI's US page). Not verified against firmware[3]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[7]Filament detection fitted; type and location not published[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designTwo auxiliary cooling fans and two air filters[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]
Input voltage (110/220 V, switch or auto)Not documented100-240 VAC, 50/60 Hz[2]
Total rated power drawNot documented350 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[8][9][1]Klipper[3]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch touchscreen[1]4.3-inch touchscreen[3]
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-driveDual-band Wi-Fi (2.4 and 5 GHz), RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[1]Wi-Fi and USB. No Ethernet listed for this model[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 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[8][9]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[10]1-year coverage (QIDI standard store terms)[11]
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[7]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[7]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.
