| Class | INDUSTRIAL | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | FlashForge Guider 3[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) | Base of a three-model series: Guider 3 (300x250x340), Guider 3 Plus (350x350x600, 250 mm/s, <50 dB, twin sealed 1 kg filament chambers) and Guider 3 Ultra (330x330x600 single-head / 300x330x600 dual-head, two extruders, 350 °C, 7-inch screen, 70 kg). Volumes and extruder counts differ across all three, so series-level spec boxes are unreliable[1][4][5] | 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] |
| Market position: superseded? successor announced? | 3DJake shows it sold out and no longer stocked; the current FlashForge store carries the Guider 3 Ultra[1][5] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 250 x 340 mm advertised[1] | 228 x 128 x 245 mm[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 350 x 315 x 455 mm[2][3] |
| Net weight (kg) | Not documented | 20 kg packaged (UniFormation publishes package weight, not net weight)[2][3] |
| Frame construction & material | Fully assembled professional chassis[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with a heated chamber; 3DJake's table records "Heated chamber: Yes". Chamber temperature not published for this model[1] | Open-frame MSLA with a UV-blocking cover[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Not documented | MSLA — photocuring LCD, single Z axis, straight-lift peel[2][3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive extruder, single[1] | Not documented |
| Hotend & Nozzle | ||
| Stock nozzle size & sizes included in box | 0.4, 0.6 and 0.8 mm nozzles available[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) | Not documented | Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[2][3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 5-inch touchscreen (control panel — not the masking LCD, see W1)[2][3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, Wi-Fi, LAN[1] | USB file transfer[2][3] |
| Materials Support | ||
| Officially supported filament list | 1.75 mm filament; 3DJake does not publish a per-material list for the base Guider 3[1] | 402.5-405 nm photopolymer resin. No closed compatibility list published[2][3] |
| 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.
