| 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 Trident, current revision R2. Sold as "Voron Trident R2 3D Printer Kit by LDO"[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] | $1,274.99 for the LDO kit at Fabreeko, on pre-order with a mid-to-late September ship estimate, checked Aug 2026. Fabreeko's live product feed shows the Trident kit at $1,199.99 and unavailable, so the figure depends on which variant is selected[3][4] |
| 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] | Two size variants on the LDO kit: Rev D 250 mm and Rev D+ 300 mm. Distinguished from the Voron 2.4 by the Z system: Trident has a fixed gantry with three Z motors lifting the bed, while the 2.4 lifts the gantry on four belted Z motors. Colour options black, space grey, blue[3][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 211.68 x 118.37 x 220 mm[1] | 250 x 250 x 250 mm or 300 x 300 x 300 mm depending on variant. Sortable value is the 300 mm kit[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 327.4 x 329.2 x 548 mm[1] | Not documented |
| Frame construction & material | Metal housing with a flip-up cover and a drip guard[1] | Aluminium-extrusion CoreXY frame, self-assembly[3] |
| Enclosure: open / enclosed; panel material; door/lid | Flip-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 with a fixed gantry; three independent Z stepper motors raise the bed and perform bed levelling[3] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Three independent Z stepper motors under the bed[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | LDO Leviathan board: 5 x TMC2209 plus 2 x TMC5160 HV-capable drivers[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Bondtech Integrated Drive Gear Assembly (IGDA) with a Clockwork 2 motor[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | E3D Revo High Flow with a 60 W heater[3] |
| Heater cartridge power (W) | Not documented | 60 W (E3D Revo High Flow heater in the LDO kit)[3] |
| Heated Bed & Surface | ||
| Bed surface (material, texture, coating), single/double-sided | Not documented | LDO bed heater with a pre-installed magnet sheet and edge-to-edge heating[3] |
| 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 also included in the kit[3] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | LDO Leviathan control board; Nitehawk SB USB toolhead board with an integrated accelerometer[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[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB 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 lighting | Not documented | COB LED chamber lighting included[3] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit[3] |
| Materials Support | ||
| Officially supported filament list | 405 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 LCD | 10-inch 16K monochrome masking LCD, 15120 x 6230 px, XY pixel pitch 14 x 19 um (manufacturer specification)[1][2] | Not documented |
| Light source | COB light source with a Fresnel collimating lens[1] | Not documented |
| Light uniformity & intensity | Light 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/h | Up to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[1] | Not documented |
| Release film | PFA release film. No rated life published[1] | Not documented |
| LCD life & replaceability | Masking 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 & feeding | Replaceable 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.
