Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[1]VzBoT AWD 330, also written Vz330. Sold as "DIY VzBoT AWD 330 VZ330 3D Printer Kit" by Mellow[2]
Release date (announcement and actual shipping)Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$219.00 on us.elegoo.com, Aug 2026, against a compare-at price of $249.00; both the Ribbon-Cable and Type-C printhead variants are the same price[3]$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)Two printhead variants of the same machine are sold under one SKU - "Ribbon-Cable Version" and "Type-C Version" - which use different printhead parts. Within the Neptune 4 family the numbers diverge sharply and get mixed up constantly: Neptune 4 is 225 x 225 x 265 mm with a 110 C bed and 20000 mm/s2; the Plus is 320 x 320 x 385 mm with a 100 C bed and 12000 mm/s2; the Max is 420 x 420 x 480 mm with an 85 C bed and only 8000 mm/s2. The Neptune 4 Pro is a separate model again[3][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[2]
Market position: superseded? successor announced?Still listed in ELEGOO's US store Neptune section in Aug 2026 alongside the 4 Pro, 4 Plus and 4 Max, but ELEGOO's current development is on the Centauri line[6]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[1]330 x 330 x 400 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)475 x 445 x 515 mm. ELEGOO separately publishes a "maximum size for machine activity" of 475 x 550 x 735 mm including rack and tray - the depth to allow for is 550 mm, not 445 mm[1]530 x 500 x 720 mm body dimensions[2]
Net weight (kg)8.3 kg net, 10.6 kg gross[1]31 kg net, 36 kg gross[2]
Frame construction & materialCNC-machined aluminium extrusion frame[1]CNC-machined all-metal frame with carbon-rod components[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian i3 bed-slinger[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]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashTwo lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[7]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)"Silent Drive (All Axes)" is all ELEGOO publishes; no driver part number is given[7]Four external TMC5160 drivers for the LDO XY motors[2]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max toolhead speed (manufacturer claim); the Neptune 4 Plus page for the same family states a recommended 250 mm/s[1][4]Not documented
Recommended/typical print speed250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[7]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 max toolhead acceleration (manufacturer claim) - notably higher than the Plus at 12000 and the Max at 8000, because the moving mass is smaller[1][4][5]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with 2 fans[7]Lightweight all-metal direct drive with a twill drive wheel[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Brass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[7]VZ High Speed hotend[2]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature[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-sidedPEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[7]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)Manual levelling combined with 121-point auto-levelling; no full-auto calibration on this model[7]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection fitted; power-loss resume printing supported[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)ELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU published[7]32-bit mainboard, quoted by Mellow at 550 Hz. Exact board model not named on the listing[2]
Input voltage (110/220 V, switch or auto)115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[1][7]Not documented
Total rated power draw310 W rated power, 24 V output[7]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[7][8]Klipper or RepRapFirmware[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour capacitive touch screen[7]5-inch DSI display; requires a compatible host computer, which is not included[2]
On-device UI capabilities (model preview, per-object controls, etc.)Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[7]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveLAN and USB file transfer; no Wi-Fi is listed for the base Neptune 4, unlike the Plus (USB/LAN/Wi-Fi) and Max (Wi-Fi/USB/WLAN)[1][4][5]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit; some parts must be printed by the buyer[2]
Materials Support
Officially supported filament listPLA, TPU, PETG, ABS, ASA, Nylon[1]Not documented
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Operating sound published as 60 dB or less - a manufacturer figure with no distance or method stated, so it is not comparable with an independently measured reading[7]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[9]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.
