Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Elegoo Saturn 4 Ultra 16K. Elegoo's product handle is saturn-4-ultra-16k-10inch-monochrome-lcd-resin-3d-printer. 3DJake item number ELG-50.101.038300[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)$649.99 in us.elegoo.com's live Shopify product JSON, in stock, with compare_at_price also $649.99 — no discount active at the time of checking (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)Distinct from the earlier Saturn 4 Ultra (12K); the 16K carries a 15120 x 6230 masking LCD with 14 x 19 um pixels. Elegoo also sells it bundled with a Mercury Plus V2.0 wash/cure station and as a pre-owned SKU, neither of which is the printer-only price[1][2]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 usable211.68 x 118.37 x 220 mm[1]330 x 330 x 400 mm[3]
Machine footprint (mm) & clearance needed (cable/spool overhang)327.4 x 329.2 x 548 mm[1]530 x 500 x 720 mm body dimensions[3]
Net weight (kg)Not documented31 kg net, 36 kg gross[3]
Frame construction & materialMetal housing with a flip-up cover and a drip guard[1]CNC-machined all-metal frame with carbon-rod components[3]
Enclosure: open / enclosed; panel material; door/lidFlip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)MSLA with tilt-release: the vat tilts to peel each layer rather than pulling straight up. Elegoo claims the mechanism cuts curing time by 25%. Single Z axis, Z precision 0.02 mm[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[3]
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[3]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedFour external TMC5160 drivers for the LDO XY motors[3]
Extruder
Type (direct drive / bowden) & design nameNot documentedLightweight all-metal direct drive with a twill drive wheel[3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedVZ High Speed hotend[3]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented120 °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-sidedNot documented8 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)Automatic levelling, plus intelligent mechanical sensor alarms[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]
Input voltage (110/220 V, switch or auto)100-240 V, 50/60 Hz, 24 V 6 A[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Elegoo EL3D-4.0 system. Slicer is CHITUBOX[1]Klipper or RepRapFirmware[3]
Connectivity, UI & Camera
Display: size, type, touch?4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]5-inch DSI display; requires a compatible host computer, which is not included[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi, with WLAN file transfer[1]Not documented
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)AI camera, 1920 x 1080[1]Not documented
Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it?AI camera with print-failure detection[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit; some parts must be printed by the buyer[3]
Materials Support
Officially supported filament list405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[1]Not documented
Resin & MSLA
Masking LCD10-inch 16K monochrome masking LCD, 15120 x 6230 px, XY pixel pitch 14 x 19 um (manufacturer specification)[1][2]Not documented
Light sourceCOB light source with a Fresnel collimating lens[1]Not documented
Light uniformity & intensityLight energy at the plate quoted as 5 mW/cm2, i.e. 5000 uW/cm2 (manufacturer claim, attributed to the tilt-release and Fresnel optics). No uniformity percentage published and no independent measurement[1]Not documented
Vertical print speedmm/hUp to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[1]Not documented
Release filmPFA release film. No rated life published[1]Not documented
LCD life & replaceabilityMasking LCD shielded by tempered 9H protective glass. Elegoo publishes no rated screen life in hours and does not state user replaceability[1]Not documented
Resin vat & feedingReplaceable resin vat with a dual pour spout and a drip guard. Heated tank with automatic temperature measurement: Elegoo states resin reaches 25 C in 26 minutes from a 5 C ambient at 50% humidity (manufacturer figure). Capacity not published; no auto-refill[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.
