| Property | Creality K2COREXY | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | Creality | UniFormation |
| Class | COREXY | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2[1] | UniFormation GKtwo 10.3" 8K Resin Printer[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[2] |
| 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] | UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 228 x 128 x 245 mm[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 404 x 436 x 545 mm[1] | 350 x 315 x 455 mm[2][3] |
| Net weight (kg) | 18.3 kg[1] | 20 kg packaged (UniFormation publishes package weight, not net weight)[2][3] |
| 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 cover[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] | MSLA — photocuring LCD, single Z axis, straight-lift peel[2][3] |
| 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 | 110/220 V[2][3] |
| 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[4][5][1] | Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[2][3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4-inch touchscreen[1] | 5-inch touchscreen (control panel — not the masking LCD, see W1)[2][3] |
| 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 file transfer[2][3] |
| 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] | 402.5-405 nm photopolymer resin. No closed compatibility list published[2][3] |
| 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[4][5] | 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[6] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Printing tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[2] |
| Resin & MSLA | ||
| Masking LCD | Not documented | 10.3-inch masking LCD, 7680 x 4320 px (8K), XY pixel pitch 29.6 um (manufacturer specification)[2][3] |
| Light source | Not documented | Photocuring LCD light engine at 402.5-405 nm. UniFormation does not publish the LED count or optical design on this page[2][3] |
| Layer exposure times | Not documented | 2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[2][3] |
| Layer height range | Not documented | 0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[2][3] |
| Resin vat & feeding | Not documented | Resin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[2][3] |
| Fume extraction | Not documented | Built-in odour filter[2][3] |
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.
