| Property | QIDI i-FastIDEX | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | QIDI | UniFormation |
| Class | IDEX | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Tech i-Fast, also written iFast and "I-Fast"[1][2] | UniFormation GKtwo 10.3" 8K Resin Printer[3][4] |
| Release date (announcement and actual shipping) | Not published on the listings checked (Aug 2026)[1][2] | Not documented |
| Street price (USD; dated snapshot per entry) | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[2][1] | $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)[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[2][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[3] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][5] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 250 x 320 mm advertised[1][2] | 228 x 128 x 245 mm[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | 350 x 315 x 455 mm[3][4] |
| Net weight (kg) | 33 kg net[2] | 20 kg packaged (UniFormation publishes package weight, not net weight)[3][4] |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Open-frame MSLA with a UV-blocking cover[3][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[1][2] | MSLA — photocuring LCD, single Z axis, straight-lift peel[3][4] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[2] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C on the high-temperature extruder assembly[1][2] | Not documented |
| Stock nozzle size & sizes included in box | 0.4 mm nozzle diameter[2] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 110-220 V[2] | 110/220 V[3][4] |
| Total rated power draw | 700 W rated[2] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[3][4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 5-inch touchscreen (control panel — not the masking LCD, see W1)[3][4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, LAN, USB flash drive[1][2] | USB file transfer[3][4] |
| Materials Support | ||
| Officially supported filament list | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[2] | 402.5-405 nm photopolymer resin. No closed compatibility list published[3][4] |
| 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[3] |
| Resin & MSLA | ||
| Masking LCD | Not documented | 10.3-inch masking LCD, 7680 x 4320 px (8K), XY pixel pitch 29.6 um (manufacturer specification)[3][4] |
| 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[3][4] |
| 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[3][4] |
| Layer height range | Not documented | 0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[3][4] |
| 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[3][4] |
| Fume extraction | Not documented | Built-in odour filter[3][4] |
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.
