| Property | UltiMaker S7INDUSTRIAL | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | UltiMaker | UniFormation |
| Class | INDUSTRIAL | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | UltiMaker S7[1] | UniFormation GKtwo 10.3" 8K Resin Printer[2][3] |
| Street price (USD; dated snapshot per entry) | $5,999.00 for the standard model at 3D Universe, in stock, 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) | Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[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| Market position: superseded?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? | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[5][6] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 240 x 300 mm[1] | 228 x 128 x 245 mm[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 495 x 585 x 780 mm with the spool holder[1] | 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 | Not documented | Open-frame MSLA with a UV-blocking cover[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual-extrusion gantry with auto nozzle-lifting and swappable print cores; kinematic layout not published[1] | MSLA — photocuring LCD, single Z axis, straight-lift peel[2][3] |
| Speed & Acceleration | ||
| Max volumetric flow claimed (mm³/s) | Build speed under 24 mm3/s (manufacturer figure)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual extrusion with swappable print cores[1] | Not documented |
| Filament diameter | 2.85 mm[1] | Not documented |
| Hotend & Nozzle | ||
| Stock nozzle size & sizes included in box | 0.4 mm standard; 0.25, 0.6 and 0.8 mm available separately[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | PEI-coated flexible build plate, 20-140 °C[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | PEI-coated flexible build plate[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 | Wi-Fi 2.4 GHz and 5 GHz, LAN, USB[1] | USB file transfer[2][3] |
| Materials Support | ||
| Officially supported filament list | Not documented | 402.5-405 nm photopolymer resin. No closed compatibility list published[2][3] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Under 50 dBA operating sound, manufacturer figure. No independent measurement[1] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification)[1] | 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.
