Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4 3D Printer[1][2]Sovol SV06 Plus ACE 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]$299.00 on sovol3d.com against a $349.00 compare-at price, in stock and shipping from US/EU/CA/AU/UK/CN warehouses, checked Aug 2026[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]Larger sibling of the SV06 ACE ($239, 220x220x250). Differs from the non-ACE SV06 Plus by Z height (350 vs 340 mm), Klipper on an RK3308, ceramic-plate hotend, 4.3-inch capacitive touchscreen and a camera. Notably it has NO power-loss recovery, which the older SV06 did have[3][4][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]
Machine footprint (mm) & clearance needed (cable/spool overhang)398 x 367 x 554 mm[1][2]510 x 575 x 710 mm including screen and filament holder[3]
Net weight (kg)18.3 kg[1][2]Not documented
Frame construction & materialNot documentedOpen i3-style frame; Sovol publishes no frame-material breakdown[3]
Enclosure: open / enclosed; panel material; door/lidEnclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1]Open frame, no enclosure[3]
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[3]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented500 mm/s maximum (manufacturer claim)[3]
Max acceleration (claimed, mm/s²)Not documented15,000 mm/s2 maximum (manufacturer claim)[3]
Extruder
Type (direct drive / bowden) & design nameNot documentedPlanetary double-gear direct drive, 1:7.5 reduction[3]
Gear ratio & drive gear materialNot documented1:7.5[3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedCeramic heating plate hotend; 0.4 mm nozzle included, 0.6 and 0.8 mm optional[3]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented<=300 °C claimed[3]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented100 °C claimed[3]
Bed surface (material, texture, coating), single/double-sidedNot documentedDouble-sided textured PEI plate[3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedAutomatic levelling (Sovol calls the ACE upgrade an added automatic levelling function); probe technology not named on this page[3]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament run-out sensor fitted; type and location not published[3]
Electronics & Power
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documentedRockchip RK3308 ("3308 chip"), 512 MB RAM, 8 GB eMMC[3]
PSU (brand, wattage, rail voltage)Not documented500 W / 24 V, 100-240 VAC 50/60 Hz[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. Sovol does not publish the fork or version on the product page. OTA updates supported[3]
Connectivity, UI & Camera
Display: size, type, touch?7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1]4.3-inch capacitive touchscreen[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2]Wi-Fi 2.4 GHz only, WPA2 only (WPA3 explicitly not supported)[3]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in camera, default 640x480, maximum 1280x720 (Sovol writes it as 1080x720P)[3]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedNone. Sovol's own spec table states "Power Loss Recovery: None" for this model[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, PVA[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.
