| Property | Formlabs Form 4RESIN | UltiMaker S7INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Formlabs | UltiMaker |
| Class | RESIN | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4 3D Printer[1][2] | UltiMaker S7[3] |
| Street price (USD; dated snapshot per entry) | Starting at $2,625.00 at GoEngineer, in stock, checked Aug 2026. Formlabs sells the printer as part of packages (Form 4 Complete Package etc.), so package prices are much higher than the printer-only figure[2] | $5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Three machines share this platform and are constantly conflated. Form 4: 200 x 125 x 210 mm, 50 um pixels, 18.3 kg, 480 W, one resin cartridge, NOT biocompatible. Form 4B: identical hardware but validated for 38 Formlabs materials including 15 biocompatible. Form 4L: 353 x 196 x 350 mm, 46 um pixels, 58.5 kg, 900 W, two cartridges[1] | 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)[3][4][5] |
| Market position: superseded? successor announced? | Not documented | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[5][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[1][2] | 330 x 240 x 300 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 367 x 554 mm[1][2] | 495 x 585 x 780 mm with the spool holder[3] |
| Net weight (kg) | 18.3 kg[1][2] | Not documented |
| Frame construction & material | Not documented | Fully assembled professional chassis[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2] | Dual-extrusion gantry with auto nozzle-lifting and swappable print cores; kinematic layout not published[3] |
| Speed & Acceleration | ||
| Max volumetric flow claimed (mm³/s) | Not documented | Build speed under 24 mm3/s (manufacturer figure)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Dual extrusion with swappable print cores[3] |
| Filament diameter | Not documented | 2.85 mm[3] |
| Hotend & Nozzle | ||
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm standard; 0.25, 0.6 and 0.8 mm available separately[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | PEI-coated flexible build plate, 20-140 °C[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | PEI-coated flexible build plate[3] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 4.8 A, 50/60 Hz, 480 W[1] | Not documented |
| Total rated power draw | 480 W[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[2] | Not documented |
| 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 (1000 Mbit), USB-C 2.0[1][2] | Wi-Fi 2.4 GHz and 5 GHz, LAN, USB[3] |
| Materials Support | ||
| Officially supported filament list | Formlabs resins across rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic and castable families. Biocompatible resins require the Form 4B, not the Form 4[1] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Under 50 dBA operating sound, manufacturer figure. No independent measurement[3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[1][2] | XYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification)[3] |
| Resin & MSLA | ||
| Masking LCD | Low Force Display masking LCD with a 50 um pixel size and pre-tuned anti-aliasing. Formlabs does not publish the screen diagonal or pixel count[1][2] | Not documented |
| Light source | Backlight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[1][2] | Not documented |
| Vertical print speedmm/h | Maximum 100 mm/h; average 40 mm/h at a 100 um layer height (manufacturer figures — GoEngineer publishes both, which is unusually explicit about the basis). Formlabs separately claims most prints finish in under 2 hours[2][1] | Not documented |
| Layer height range | 25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[1][2] | Not documented |
| Resin vat & feeding | Single next-generation resin cartridge; Formlabs claims 5-10x faster filling and 63% less waste. Resin tank rated for 75,000+ layers with any Formlabs material. No vat capacity published[1][2] | 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.
