| Class | COREXY | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2[1] | Phrozen Sonic Mini 8K S 7.1" LCD 3D Printer. Manufacturer number 51010040501102[2][3][4] |
| Street price (USD; dated snapshot per entry) | Not documented | $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) | 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] | 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][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 165 x 72 x 170 mm[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 404 x 436 x 545 mm[1] | 290 x 290 x 430 mm[2][4] |
| Net weight (kg) | 18.3 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, 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] | Open-frame MSLA with a UV-blocking plastic cover[2] |
| 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?) | 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] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | Not documented |
| 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] | Not documented |
| 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] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One auxiliary cooling fan and one air filter[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[6][7][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-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 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] | USB only[2][4] |
| 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] | 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[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] | 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][5] |
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.
