Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2 Pro[1]Phrozen Sonic Mighty Revo 14K 10.1" LCD 3D Printer[2][3][4]
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[5]$680.00 on us.phrozen3d.com but unavailable — backordered, shipping when back in stock, checked Aug 2026. 3DJake also shows it sold out and delisted[4][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]The Sonic Mighty family spans several resolutions at the same 10.1-inch size and very different prices: Mighty 4K $149, Mighty 8K $410, Mighty 12K $329, Mighty Revo 14K $680, Mighty 16K $720. A "Sonic Mighty" spec box is meaningless without the resolution suffix. Sources also disagree on this model's own numbers: Phrozen gives machine dimensions 353 x 345 x 517 mm and XY 16.8 x 24.8 um, while 3DJake gives 228 x 337 x 516 mm and XY 16.8 x 24 um. Phrozen's own figures are used here. 8 GB onboard storage[3][2][4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 x 300 x 300 mm[1]223 x 126 x 235 mm[2][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)445 x 477 x 573 mm[1]353 x 345 x 517 mm per Phrozen. 3DJake publishes 228 x 337 x 516 mm, which cannot be right for a machine with a 223 mm-wide build area[4][2]
Net weight (kg)23.7 kg[1]18 kg[4]
Enclosure: open / enclosed; panel material; door/lidEnclosed with chamber temperature control up to 60 C; one air filter[1]Open-frame MSLA with a UV-blocking 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 dual linear guide rails with a ball screw, straight-lift peel[2][4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedDual linear guide rails with a ball screw[2][4]
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]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 limit110 C max heatbed temperature[1]Not documented
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 levelling[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designOne auxiliary cooling fan and one air filter[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documentedAC 100-240 V, 50/60 Hz[4]
Total rated power drawNot documented240 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. File formats accepted are .ctb and .prz[2][4]
Connectivity, UI & Camera
Display: size, type, touch?4-inch touchscreen[1]5-inch touch panel (control panel — not the masking LCD, see W1)[2][4]
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]USB and Wi-Fi[2][4]
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]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 LCDNot documented10.1-inch 14K monochrome masking LCD, 13,320 x 5,120 px, XY pixel pitch 16.8 x 24.8 um per Phrozen (3DJake writes 16.8 x 24 um)[4][2]
Light sourceNot documentedLinear projection LED module. Wavelength not published[4]
Layer height rangeNot documented0.01-0.30 mm[4]
Release filmNot documentednFEP film supplied. No rated life published[2][4]
Resin vat & feedingNot documentedBuilt-in resin heater fitted; Phrozen publishes no setpoint, no vat capacity, no auto-refill and no level sensing for this model[2][4]
Fume extractionNot documentedPlug-in air purifier supplied with the machine[2]
Throughputlayers/hNot documentedAvg. 450 layers/h on Phrozen's own product page — the only throughput figure Phrozen publishes for this model, and it publishes no mm/h at all. 3DJake states 400 layers/h for the same machine; Phrozen's own figure is used here, as elsewhere in this entry. Manufacturer claim, not a measurement, and neither source states the layer height assumed. W4 is deliberately empty: the layer range is 0.01-0.30 mm, so any mm/h conversion would be invented rather than measured[4][2]

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.
