| Property | Formlabs Form 4LRESIN | Stratasys F120INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Formlabs | Stratasys |
| Class | RESIN | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4L[1] | Stratasys F120, part of the Stratasys F123 Series[2] |
| Release date (announcement and actual shipping) | Not documented | The F123 series spec sheet carried is revision 0721a (July 2021). Stratasys does not print a launch date on it[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Same Low Force Display engine as the Form 4 but a different machine on every physical figure: 353 x 196 x 350 mm vs 200 x 125 x 210, 46 um vs 50 um pixels, 58.5 kg vs 18.3 kg, 900 W vs 480 W, two resin cartridges vs one. Formlabs lists Basic, Premium and Complete packages, whose prices are not printer-only prices, and no printer-only USD figure was found on a live listing[1] | 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[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1] | 254 x 254 x 254 mm (10 x 10 x 10 in)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 664 x 528 x 794 mm[1] | 889 x 870 x 721 mm (35 x 35 x 29 in)[2] |
| Net weight (kg) | 58.5 kg[1] | 124 kg (F120) or 227 kg with consumables (F170, F270, F370)[2] |
| Frame construction & material | Not documented | Fully enclosed office/classroom-grade cabinet, factory assembled[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1] | Enclosed build chamber[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 9 A, 50/60 Hz, 900 W[1] | 100-132 V / 15 A or 200-240 V / 7 A, 50/60 Hz[2] |
| Total rated power draw | 900 W[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary; print preparation is PreForm[1] | 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[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1] | 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[2] |
| Materials Support | ||
| Officially supported filament list | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1] | 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[2] |
| Safety | ||
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | CE (low-voltage and EMC directives), FCC, EAC, cTUVus, KC, RoHS, WEEE, REACH, RCM[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | 46 dB maximum during build, 35 dB idle — manufacturer specification, no distance or method stated, and not an independent measurement[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification[1] | 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[2] |
| Resin & MSLA | ||
| Masking LCD | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[1] | Not documented |
| Light source | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[1] | Not documented |
| Layer height range | 25-200 um[1] | Not documented |
| Resin vat & feeding | Two next-generation resin cartridges. No vat capacity published[1] | Not documented |
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.
