| Property | Formlabs Form 4LRESIN | Sovol SV07 PlusBEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | Formlabs | Sovol |
| Class | RESIN | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4L[1] | Sovol SV07 Plus[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $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[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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] | 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[3][2] |
| Market position: superseded? successor announced? | Not documented | Delisted by Sovol; not present in the current 3D-printer collection[4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1] | 300 x 300 x 350 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 664 x 528 x 794 mm[1] | 632 x 532 x 735 mm[2] |
| Net weight (kg) | 58.5 kg[1] | 14 kg[2] |
| Frame construction & material | Not documented | Open frame, assembly kit[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a 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) with the Low Force Display engine; straight-lift peel[1] | Cartesian i3 bedslinger[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | Up to 500 mm/s (manufacturer claim); the retailer listing gives a 250-500 mm/s working range[3][2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Dual-gear direct drive with planetary gearbox[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | All-metal hotend to 300 °C, 0.4 mm nozzle[3][2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=300 °C claimed[3][2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=100 °C claimed[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | 25-point automatic levelling; probe technology not stated[3] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 25 points (manufacturer claim)[3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Enhanced triple cooling (Sovol's wording; no fan detail published)[3] |
| Electronics & Power | ||
| PSU (brand, wattage, rail voltage) | Not documented | 600 W MeanWell, 24 V, 115/230 V AC input[3][2] |
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 9 A, 50/60 Hz, 900 W[1] | Not documented |
| Total rated power draw | 900 W[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary; print preparation is PreForm[1] | Klipper[3] |
| 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[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1] | Wi-Fi, USB and USB Type-C[3][2] |
| Materials Support | ||
| Officially supported filament list | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1] | PLA, PETG, TPU, ABS, wood-filled; Sovol also lists carbon fibre[2][3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification[1] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[1] | Not documented |
| Light source | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[1] | Not documented |
| Layer height range | 25-200 um[1] | Not documented |
| Resin vat & feeding | Two next-generation resin cartridges. No vat capacity published[1] | 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.
