Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4 3D Printer[1][2]Sovol Zero 3D Printer[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]$389.00 on sovol3d.com against a $499.00 compare-at price, but marked Sold out, checked Aug 2026. Sovol's own announcement article quotes from $359.00[3][4][5]
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]No sibling variants at the time of checking. Sovol positions it against the Voron 0 and Bambu Lab P1P. Note the bed and nozzle limits are higher than the larger SV08 (120 vs 100 °C bed, 350 vs 300 °C nozzle), so SV08 figures must not be carried across[3][5][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[1][2]152.4 x 152.4 x 152.5 mm advertised[3][5]
Machine footprint (mm) & clearance needed (cable/spool overhang)398 x 367 x 554 mm[1][2]345 x 420 x 475 mm[3]
Net weight (kg)18.3 kg[1][2]Not documented
Frame construction & materialNot documentedFull linear rails on all axes; CoreXY with two motors sharing the moving mass[5]
Enclosure: open / enclosed; panel material; door/lidEnclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1]Fully enclosed[5]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2]CoreXY[5]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedLinear rails on all axes[5]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented1200 mm/s maximum (manufacturer claim). Sovol's own material acknowledges 700 mm/s as the realistic figure for detailed prints[3][5]
Max acceleration (claimed, mm/s²)Not documented40,000 mm/s2 maximum (manufacturer claim)[3][5]
Max volumetric flow claimed (mm³/s)Not documented<=50 mm3/s (manufacturer claim)[3]
Extruder
Type (direct drive / bowden) & design nameNot documentedPlanetary-gear direct-drive extruder[3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedCeramic heating plate. Brass or hardened-steel nozzles in 0.2/0.4/0.6/0.8/1.0 mm[3]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented<=350 °C claimed[3][5]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedBrass or hardened steel, buyer's choice[3]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented<=120 °C claimed; Sovol states the bed is AC-heated[3][5]
Bed surface (material, texture, coating), single/double-sidedNot documentedDouble-sided PEI steel plate[3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedEddy-current scanning combined with pressure (force) sensing — Sovol describes it as an inductive sensor plus force sensor[3][5]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament sensor fitted; type and location not published[3][5]
Electronics & Power
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documentedAllwinner H616, 1 GB RAM, 8 GB eMMC, 64-bit[3]
PSU (brand, wattage, rail voltage)Not documented150 W / 24 V (this is the DC supply; the bed is separately AC-heated per Sovol)[3][5]
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]Not named on the product page beyond OTA updates and OrcaSlicer support; Sovol markets the machine as open source[3][5]
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-driveDual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2]Ethernet and Wi-Fi 2.4 GHz, WPA2 only (WPA3 not supported)[3][5]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in camera for monitoring; resolution not published[3][5]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedArrives preassembled[5]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery supported; mechanism not published[3][5]
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, PETG-CF, ABS, ASA, PA, PC[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]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.
