Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[1]VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[2]
Street price (USD; dated snapshot per entry)Not documented$1,360.00 at Mellow, available and shipping from China, checked Aug 2026[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[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[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable180 x 180 x 165 mm[1]330 x 330 x 400 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1]530 x 500 x 720 mm body dimensions[2]
Net weight (kg)3 kg net; 5.5 kg with the hard case[1]31 kg net, 36 kg gross[2]
Frame construction & materialFolding frame designed to fit in a filament box; supplied with a black hard case[1]CNC-machined all-metal frame with carbon-rod components[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY, inverted — the machine prints upside down[1]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[2]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedLDO 9 mm rail on X; LDO 12 mm dual rails on Y; 10 mm optical shafts on Z[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedFour external TMC5160 drivers for the LDO XY motors[2]
Speed & Acceleration
Max print speed (claimed, mm/s)250 mm/s maximum print speed (manufacturer claim)[1]Not documented
Max acceleration (claimed, mm/s²)8,000 mm/s2 (manufacturer claim)[1]Not documented
Extruder
Type (direct drive / bowden) & design nameBowden-style, single extrusion[1]Lightweight all-metal direct drive with a twill drive wheel[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)PS plated-copper nozzle, 0.4 mm[1]VZ High Speed hotend[2]
Max nozzle temp claimed AND firmware max temp limit (both values)260 °C maximum (manufacturer claim)[1]Not documented
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Plated copper[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[1]120 °C maximum bed temperature (manufacturer claim)[2]
Bed heater type (DC/AC mains) & wattageNot documented750 W silicone bed heater on an 8 mm aluminium plate[2]
Bed surface (material, texture, coating), single/double-sidedHeated removable ITO glass bed[1]8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)LDO Positron mainboard[1]32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[2]
PSU (brand, wattage, rail voltage)DC 24 V, 200 W[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Klipper[1]Klipper or RepRapFirmware[2]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch LCD touchscreen[1]5-inch DSI display; requires a compatible host computer, which is not included[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi, USB, Ethernet[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printSelf-assembly kit, manufactured in China[1]Self-assembly kit; some parts must be printed by the buyer[2]
Materials Support
Officially supported filament listPLA and PETG only, per the manufacturer[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.
