| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2 Plus[1] | Phrozen Sonic Mini 8K S 7.1" LCD 3D Printer. Manufacturer number 51010040501102[2][3][4] |
| Street price (USD; dated snapshot per entry) | $999.00 on store.creality.com, Aug 2026[5] | $270.00 on us.phrozen3d.com, backordered with an end-of-September ETA, checked Aug 2026. The collection page rendered it as unavailable on the same day[4][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] | Phrozen's 7.1-inch line is easy to confuse: the Sonic Mini 8K S ($270) sits beside the older Sonic Mini 8K ($340, sold out) and the 5.5-inch Sonic Mini ($129.99). The 10.1-inch Sonic Mighty family is a different size class entirely. The 8K S is the only one of the group with a single linear rail and a lead screw rather than a ball screw[3][2][4][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 350 x 350 x 350 mm[1] | 165 x 72 x 170 mm[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 495 x 515 x 640 mm[1] | 290 x 290 x 430 mm[2][4] |
| Net weight (kg) | 35 kg[1] | 10 kg[2][4] |
| Frame construction & material | Not documented | Black textured housing with a neon-green plastic cover[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with chamber temperature control up to 60 C and two air filters[1] | Open-frame MSLA with a UV-blocking plastic cover[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] | MSLA, single Z axis on one linear rail with a lead screw, straight-lift peel[2][4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | One linear rail; lead screw (not a ball screw)[2][4] |
| 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] | Not documented |
| 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[7] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature[1] | Not documented |
| Heater cartridge power (W) | 100 W rated hotend power[1] | Not documented |
| 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[7] | 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[7] | 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 | 24 V DC, 2 A[4] |
| Total rated power draw | Not documented | 48 W maximum system power[4] |
| 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] | Not named by Phrozen. Native file format .PRZ; compatible slicers CHITUBOX, Lychee and VoxelDance Tango[2][4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch touchscreen[1] | 3.5-inch touch panel (control panel — not the masking LCD, see W1)[4] |
| 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] | USB only[2][4] |
| 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] | 405 nm photopolymer resin; no closed compatibility list published[2] |
| 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] | 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[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 |
| Resin & MSLA | ||
| Masking LCD | Not documented | 7.1-inch 8K monochrome masking LCD, XY pixel pitch 22 um. Phrozen does not publish the pixel count for this model[2][4] |
| Light source | Not documented | Linear projection LED module. Wavelength not published for this model[2][4] |
| Vertical print speedmm/h | Not documented | Max 80 mm/h (manufacturer claim). Phrozen does not state the layer height or resin type the figure assumes[4] |
| Layer height range | Not documented | 0.01-0.30 mm[4] |
| Release film | Not documented | FEP film — note this is plain FEP, whereas the Sonic Mighty Revo 14K ships nFEP. No rated life published[4][6] |
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.
