| Class | RESIN | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | UniFormation GKtwo 10.3" 8K Resin Printer[1][2] | VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[3] |
| Street price (USD; dated snapshot per entry) | $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)[1] | $1,360.00 at Mellow, available and shipping from China, checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1] | Ordered by colour (black or silver) and mains voltage (110 V or 220 V). Mellow describes the kit as a test version that still requires the buyer to print some components, and the 5-inch DSI screen requires a host computer that supports DSI — neither is included[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 228 x 128 x 245 mm[1][2] | 330 x 330 x 400 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 350 x 315 x 455 mm[1][2] | 530 x 500 x 720 mm body dimensions[3] |
| Net weight (kg) | 20 kg packaged (UniFormation publishes package weight, not net weight)[1][2] | 31 kg net, 36 kg gross[3] |
| Frame construction & material | Not documented | CNC-machined all-metal frame with carbon-rod components[3] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a UV-blocking cover[1][2] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | MSLA — photocuring LCD, single Z axis, straight-lift peel[1][2] | CoreXY in an AWD (all-wheel drive) arrangement — two motors on X and two on Y, four in total for the XY plane, each on its own external driver[3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | LDO 9 mm rail on X; LDO 12 mm dual rails on Y; 10 mm optical shafts on Z[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Four external TMC5160 drivers for the LDO XY motors[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Lightweight all-metal direct drive with a twill drive wheel[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | VZ High Speed hotend[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 120 °C maximum bed temperature (manufacturer claim)[3] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 750 W silicone bed heater on an 8 mm aluminium plate[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | 8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[3] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | 32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[3] |
| Input voltage (110/220 V, switch or auto) | 110/220 V[1][2] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[1][2] | Klipper or RepRapFirmware[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch touchscreen (control panel — not the masking LCD, see W1)[1][2] | 5-inch DSI display; requires a compatible host computer, which is not included[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB file transfer[1][2] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; some parts must be printed by the buyer[3] |
| Materials Support | ||
| Officially supported filament list | 402.5-405 nm photopolymer resin. No closed compatibility list published[1][2] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Printing tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[1] | Not documented |
| Resin & MSLA | ||
| Masking LCD | 10.3-inch masking LCD, 7680 x 4320 px (8K), XY pixel pitch 29.6 um (manufacturer specification)[1][2] | Not documented |
| Light source | Photocuring LCD light engine at 402.5-405 nm. UniFormation does not publish the LED count or optical design on this page[1][2] | Not documented |
| Layer exposure times | 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[1][2] | Not documented |
| Layer height range | 0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[1][2] | Not documented |
| Resin vat & feeding | 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[1][2] | Not documented |
| Fume extraction | Built-in odour filter[1][2] | 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.
