| Property | Stratasys F120INDUSTRIAL | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | Stratasys | UniFormation |
| Class | INDUSTRIAL | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Stratasys F120, part of the Stratasys F123 Series[1] | UniFormation GKtwo 10.3" 8K Resin Printer[2][3] |
| Release date (announcement and actual shipping) | The F123 series spec sheet carried is revision 0721a (July 2021). Stratasys does not print a launch date on it[1] | Not documented |
| 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) | The F120 is the odd one out in the series: smaller cabinet (889 x 870 x 721 mm, 124 kg vs 1,626 x 864 x 711 mm, 227 kg), two external material coil boxes rather than internal spool bays, only two model materials, and no 0.127 mm layer option. Same build size as the F170 but not the same machine[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 | 254 x 254 x 254 mm (10 x 10 x 10 in)[1] | 228 x 128 x 245 mm[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 889 x 870 x 721 mm (35 x 35 x 29 in)[1] | 350 x 315 x 455 mm[2][3] |
| Net weight (kg) | 124 kg (F120) or 227 kg with consumables (F170, F270, F370)[1] | 20 kg packaged (UniFormation publishes package weight, not net weight)[2][3] |
| Frame construction & material | Fully enclosed office/classroom-grade cabinet, factory assembled[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed build chamber[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] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-132 V / 15 A or 200-240 V / 7 A, 50/60 Hz[1] | 110/220 V[2][3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary Stratasys firmware; print preparation is GrabCAD Print. The F370 additionally carries an Insight software licence and DoD STIG compliance powered by Red Hat Enterprise Linux[1] | 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 | Wired TCP/IP at 100 Mbps minimum, 100base-T Ethernet, RJ45. Wireless-ready IEEE 802.11 n/g/b with WPA2-PSK or 802.1x EAP, CCMP/TKIP encryption[1] | USB file transfer[2][3] |
| Materials Support | ||
| Officially supported filament list | ABS-M30 and ASA, with SR-30 support material. Notably the F120 does NOT get PLA, FDM TPU 92A or ABS-CF10, and cannot use the 0.127 mm layer height[1] | 402.5-405 nm photopolymer resin. No closed compatibility list published[2][3] |
| Safety | ||
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | CE (low-voltage and EMC directives), FCC, EAC, cTUVus, KC, RoHS, WEEE, REACH, RCM[1] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 46 dB maximum during build, 35 dB idle — manufacturer specification, no distance or method stated, and not an independent measurement[1] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Parts produced within +/-0.200 mm or +/-0.002 mm/mm, whichever is greater. Manufacturer figure derived from statistical data at 95% dimensional yield; Z accuracy carries an extra -0.000/+slice-height tolerance[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.
