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]Voron 2.4, current revision R2, kits shipping as Rev D and Rev D+. Sold as "Voron 2.4 R2 (Rev D+) 3D Printer Kit by LDO"[3][4]
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]$1,399.99 for the LDO Rev D+ kit at Fabreeko (300 mm and 350 mm are the same price), on pre-order with a mid-September estimate, checked Aug 2026. Fabreeko's live feed shows the base 2.4 kit listing at $1,299.99 and available. 3DJake lists an LDO 350 RevD kit but will not ship to the US[3][5][6]
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]Sizes 250, 300 and 350 mm; LDO ships Rev D and Rev D+. Colours black, space grey, blue. Do not confuse with the Trident: the 2.4 lifts the whole gantry on four belted Z motors, the Trident lifts the bed on three screws. The Rev D+ kit includes a Raspberry Pi 4B; the older 3DJake-listed RevD kit explicitly does not include a Pi[3][4][6][7]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable211.68 x 118.37 x 220 mm[1]300 x 300 x 300 mm or 350 x 350 x 350 mm. Sortable value is the 350 mm kit[3][4][6]
Machine footprint (mm) & clearance needed (cable/spool overhang)327.4 x 329.2 x 548 mm[1]Not documented
Frame construction & materialMetal housing with a flip-up cover and a drip guard[1]Blind-joint aluminium-extrusion frame with a complete panel set; stainless-steel linear rails throughout[4][6]
Enclosure: open / enclosed; panel material; door/lidFlip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[1]Enclosed by the supplied panel set. A Nevermore Micro V5 internal circulation filter is included in the LDO kit[6]
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 on linear rails, with a belted flying gantry on four Z motors[4][3]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedLDO Leviathan board: 5 x TMC2209 plus 2 x TMC5160 HV-capable drivers, ready for 48 V upgrades[3]
Extruder
Type (direct drive / bowden) & design nameNot documentedClockwork 2 with a Bondtech BMG / Integrated Drive Gear Assembly, in a Stealthburner toolhead[3][4][6]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedE3D Revo Voron (24 V), all-metal, high-flow variant in the Rev D+ kit, with a 60 W heater; upgradeable to a Phaetus Rapido HF for $9.99[3][4][6]
Heater cartridge power (W)Not documented60 W (E3D Revo High Flow heater)[3]
Heated Bed & Surface
Bed surface (material, texture, coating), single/double-sidedNot documentedCast 5083 aluminium plate with a magnetic base and a powder-coated PEI sheet; LDO silicone bed heater with edge-to-edge heating[4][3][6]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic levelling, plus intelligent mechanical sensor alarms[1]Omron inductive probe supplied; Klicky-mod parts included. Voron Tap is available as an add-on rather than standard[3][4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedLDO x Voron Leviathan mainboard (replacing the earlier BTT Octopus), plus a Nitehawk SB USB toolhead PCB[4][3][6]
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, hosted on a Raspberry Pi 4B (included in the Fabreeko Rev D+ kit, not in the older 3DJake RevD kit)[3][4][6]
Connectivity, UI & Camera
Display: size, type, touch?4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]4.3-inch touchscreen included in the LDO kit[6]
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
LED chamber/toolhead lightingNot documentedCOB LED strips included[3][6]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit; some parts must be printed by the user, and the LDO kit supplies pre-cut, pre-crimped cables and a heat-set insert soldering tip[6]
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.
