| Property | FlashForge Creator 4IDEX | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | FlashForge | UniFormation |
| Class | IDEX | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Flashforge Creator 4, sold in A and S configurations (Creator 4A, Creator 4S)[1] | UniFormation GKtwo 10.3" 8K Resin Printer[2][3] |
| Street price (USD; dated snapshot per entry) | $10,999.00 at Top 3D Shop with a 2-3 week lead time, checked Aug 2026[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)[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Two factory configurations that share the chassis but not the temperature ceiling: Creator 4A ships 2 x HT extruders (320 °C max, no composite support), Creator 4S ships 1 x HT + 1 x HS (360 °C max, supports PA-CF, PA-GF, PP-CF, PPS-CF). A third extruder type, F, is rated 265 °C and intended for flexibles. Any published "360 °C" figure applies only to the HS head[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 | 400 x 350 x 500 mm[1] | 228 x 128 x 245 mm[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 840 x 675 x 1000 mm (1050 mm on the stand). FlashForge specifies an installation space of at least 1400 x 1500 x 1600 mm[1] | 350 x 315 x 455 mm[2][3] |
| Net weight (kg) | 90 kg net[1] | 20 kg packaged (UniFormation publishes package weight, not net weight)[2][3] |
| Frame construction & material | Fully enclosed professional chassis on a stand[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with HEPA 13 filtration and an actively controlled chamber[1] | Open-frame MSLA with a UV-blocking cover[2][3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Up to 65 °C, actively controlled (manufacturer claim)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | IDEX — two independently driven extruders on the same gantry[1] | MSLA — photocuring LCD, single Z axis, straight-lift peel[2][3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 10-200 mm/s, adjustable per material. On the 4S the HS head is quoted 100-150 mm/s and the HT head 100-200 mm/s (manufacturer figures)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive, two independent extruders, interchangeable modules (F / HT / HS)[1] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Depends on the fitted extruder module: F 265 °C, HT 320 °C, HS 360 °C[1] | Not documented |
| Stock nozzle size & sizes included in box | 0.4 mm default; 0.6 and 0.8 mm optional[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 130 °C maximum (manufacturer claim)[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic bed levelling; FlashForge does not name the probe technology in this spec table[1] | Not documented |
| Filament Handling & Detection | ||
| Spool holder location & max spool size; drybox compatibility | Two spool bays, 1 kg and 2 kg capacity[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | AC 100-130 V / 200-240 V, 50-60 Hz, 30 A overcurrent protection[1] | 110/220 V[2][3] |
| Total rated power draw | 2320 W rated[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named; the supported slicer is FlashPrint[1] | Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[2][3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 7-inch touchscreen, 1024 x 600[1] | 5-inch touchscreen (control panel — not the masking LCD, see W1)[2][3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB flash drive, Ethernet, Wi-Fi[1] | USB file transfer[2][3] |
| Materials Support | ||
| Officially supported filament list | Standard and engineering plastics on the HT head; the HS head adds PA-CF, PA-GF, PP-CF and PPS-CF. Materials such as PC, PA and carbon fibre are the stated targets for the 130 °C bed[1] | 402.5-405 nm photopolymer resin. No closed compatibility list published[2][3] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 12 months on the printer, 3 months on extruder parts[1] | 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.
