Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4 3D Printer[1][2]Sovol SV07 Plus[3][4]
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]$199 at 3D Printers Online Store, reduced from $379, but Out of Stock, checked Aug 2026. Sovol's own comparison quotes $259 sale / $309-379 regular[3][4]
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]Large-format version of the SV07. Distinguishers: 300x300x350 mm vs 220x220x250, 600 W MeanWell vs 350 W, 25-point levelling, and USB Type-C added. Both are quoted at 500 mm/s and 300 °C. Note Sovol's own comparison table gives 300x300x350 while some listings write 300x300x340[4][3]
Market position: superseded? successor announced?Not documentedDelisted by Sovol; not present in the current 3D-printer collection[5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[1][2]300 x 300 x 350 mm advertised[3][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)398 x 367 x 554 mm[1][2]632 x 532 x 735 mm[3]
Net weight (kg)18.3 kg[1][2]14 kg[3]
Frame construction & materialNot documentedOpen frame, assembly kit[4]
Enclosure: open / enclosed; panel material; door/lidEnclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1]Open frame, no enclosure[4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2]Cartesian i3 bedslinger[4]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documentedUp to 500 mm/s (manufacturer claim); the retailer listing gives a 250-500 mm/s working range[4][3]
Extruder
Type (direct drive / bowden) & design nameNot documentedDual-gear direct drive with planetary gearbox[4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedAll-metal hotend to 300 °C, 0.4 mm nozzle[4][3]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented<=300 °C claimed[4][3]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented<=100 °C claimed[3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documented25-point automatic levelling; probe technology not stated[4]
Mesh grid size (probe point count — firmware evidence)Not documented25 points (manufacturer claim)[4]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedEnhanced triple cooling (Sovol's wording; no fan detail published)[4]
Electronics & Power
PSU (brand, wattage, rail voltage)Not documented600 W MeanWell, 24 V, 115/230 V AC input[4][3]
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 draw480 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]Klipper[4]
Connectivity, UI & Camera
Display: size, type, touch?7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1]5-inch touchscreen[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2]Wi-Fi, USB and USB Type-C[4][3]
Materials Support
Officially supported filament listFormlabs 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]PLA, PETG, TPU, ABS, wood-filled; Sovol also lists carbon fibre[3][4]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)XY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[1][2]Not documented
Resin & MSLA
Masking LCDLow 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 sourceBacklight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[1][2]Not documented
Vertical print speedmm/hMaximum 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 range25-200 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 & feedingSingle 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.
