Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Snapmaker U1 3D Printer[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)$849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[1]$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)An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[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 usable270 x 270 x 270 mm[1]330 x 330 x 400 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)584 x 499 x 730 mm[1]530 x 500 x 720 mm body dimensions[2]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[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]

Extruder
Type (direct drive / bowden) & design nameNot documentedLightweight all-metal direct drive with a twill drive wheel[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedVZ High Speed hotend[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 °C maximum (manufacturer claim)[1]Not documented
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Stainless steel as standard; hardened steel needed for fibre-filled grades[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 °C maximum (manufacturer claim)[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-sidedFlexible steel sheet with a PEI surface[1]8 mm aluminium plate with a magnetic spring-steel PEI-coated sheet[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out detection, plus air-printing detection and RFID filament recognition[1]Not documented
Multi-material/multi-color capability or official upgrade pathFour toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designMain plus auxiliary part-cooling fans[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[2]
Total rated power drawMaximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[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.
