|---|---|---|
| Identity | ||
| Brand | QIDI | VzBoT |
| Class | IDEX | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Tech i-Fast, also written iFast and "I-Fast"[1][2] | VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[3] |
| Release date (announcement and actual shipping) | Not published on the listings checked (Aug 2026)[1][2] | Not documented |
| Street price (USD; dated snapshot per entry) | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[2][1] | $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) | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[2][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] |
| Market position: superseded? successor announced? | Discontinued; QIDI's current line is the Q, Plus and Max series[2][4] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 250 x 320 mm advertised[1][2] | 330 x 330 x 400 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 710 x 510 x 670 mm[2] | 530 x 500 x 720 mm body dimensions[3] |
| Net weight (kg) | 33 kg net[2] | 31 kg net, 36 kg gross[3] |
| Frame construction & material | Fully assembled enclosed metal-frame machine[1] | CNC-machined all-metal frame with carbon-rod components[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Dual independent extruders in an enclosed Cartesian gantry[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] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[2] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive, two extruders. MK10-style nozzle[1][2] | 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] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C on the high-temperature extruder assembly[1][2] | Not documented |
| Stock nozzle size & sizes included in box | 0.4 mm nozzle diameter[2] | Not documented |
| 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) | 110-220 V[2] | Not documented |
| Total rated power draw | 700 W rated[2] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | Klipper or RepRapFirmware[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 5-inch DSI display; requires a compatible host computer, which is not included[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, LAN, USB flash drive[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 | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[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.
