| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4 3D Printer[1][2] | Formlabs Form 4L[1] |
| 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] | Not documented |
| 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 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] |
| 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] | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 367 x 554 mm[1][2] | 664 x 528 x 794 mm[1] |
| Net weight (kg) | 18.3 kg[1][2] | 58.5 kg[1] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1] | Enclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2] | Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 4.8 A, 50/60 Hz, 480 W[1] | 100-240 VAC, 9 A, 50/60 Hz, 900 W[1] |
| Total rated power draw | 480 W[1] | 900 W[1] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[2] | Proprietary; print preparation is PreForm[1] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1] | 7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2] | Dual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1] |
| 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] | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[1][2] | XY dimensional tolerance +/-0.15% — a manufacturer specification[1] |
| 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] | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[1] |
| Light source | Backlight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[1][2] | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[1] |
| 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] | 25-200 um[1] |
| 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] | Two next-generation resin cartridges. No vat capacity published[1] |
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.
