Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[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)$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[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)Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[1][4][5]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 usable175 x 180 x 170 mm advertised[1][2]330 x 330 x 400 mm[3]
Machine footprint (mm) & clearance needed (cable/spool overhang)370 x 362 x 397 mm[1]530 x 500 x 720 mm body dimensions[3]

Kinematics & Motion Hardware

Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[1][2]VZ High Speed hotend[3]
Max nozzle temp claimed AND firmware max temp limit (both values)<=300 °C claimed[1][2]Not documented
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Brass[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit<=120 °C claimed[1][2]120 °C maximum bed temperature (manufacturer claim)[3]
Bed heater type (DC/AC mains) & wattageNot documented750 W silicone bed heater on an 8 mm aluminium plate[3]
Bed surface (material, texture, coating), single/double-sidedDouble-sided flexible magnetic RF plate[1]8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)16-point automatic bed levelling per QIDI's US page; probe technology not named[2]Not documented
Mesh grid size (probe point count — firmware evidence)16 points (QIDI's US page). Not verified against firmware[2]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection fitted; type and location not published[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documented32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[3]
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxCortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[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.
