| Property | Formlabs Form 4RESIN | VzBoT AWD 330COREXY |
|---|---|---|
| Identity | ||
| Brand | Formlabs | VzBoT |
| Class | RESIN | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4 3D Printer[1][2] | VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[3] |
| 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] | $1,360.00 at Mellow, available and shipping from China, checked Aug 2026[3] |
| 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] | Ordered by colour (black or silver) and mains voltage (110 V or 220 V). Mellow describes the kit as a test version that still requires the buyer to print some components, and the 5-inch DSI screen requires a host computer that supports DSI — neither is included[3] |
| 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] | 330 x 330 x 400 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 367 x 554 mm[1][2] | 530 x 500 x 720 mm body dimensions[3] |
| Net weight (kg) | 18.3 kg[1][2] | 31 kg net, 36 kg gross[3] |
| Frame construction & material | Not documented | CNC-machined all-metal frame with carbon-rod components[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2] | CoreXY in an AWD (all-wheel drive) arrangement — two motors on X and two on Y, four in total for the XY plane, each on its own external driver[3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | LDO 9 mm rail on X; LDO 12 mm dual rails on Y; 10 mm optical shafts on Z[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Four external TMC5160 drivers for the LDO XY motors[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Lightweight all-metal direct drive with a twill drive wheel[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | VZ High Speed hotend[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 120 °C maximum bed temperature (manufacturer claim)[3] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 750 W silicone bed heater on an 8 mm aluminium plate[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | 8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[3] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | 32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[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 draw | 480 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 or RepRapFirmware[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 DSI display; requires a compatible host computer, which is not included[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; some parts must be printed by the buyer[3] |
| 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] | Not documented |
| 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 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] | Not documented |
| Light source | Backlight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[1][2] | Not documented |
| 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] | Not documented |
| 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] | 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.
