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]Flashforge Guider 3 Ultra; the FlashForge spec table gives the machine name as "Guider 3 Ultra"[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]$2,399.00 against a $3,499.00 regular price on flashforge.com, but the listing checked is the refurbished SKU and is marked Sold out (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]Top of the Guider 3 series. Build size depends on which head is used: 330 x 330 x 600 mm with one extruder, 300 x 330 x 600 mm with both. Siblings Guider 3 (300x250x340) and Guider 3 Plus (350x350x600) are both single-extruder. A refurbished SKU exists alongside the new machine, so check which one a price refers to[3][4][5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable211.68 x 118.37 x 220 mm[1]330 x 330 x 600 mm with a single extruder; 300 x 330 x 600 mm when both extruders are in use[3]

Enclosure: open / enclosed; panel material; door/lidFlip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[1]Closed design with an air filter fitted[3]
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 two extruders, per a third-party buyer's guide. FlashForge's own spec table does not state the kinematics[6][3]

Max acceleration (claimed, mm/s²)Not documented20,000 mm/s2 maximum (manufacturer claim)[3]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedActive vibration compensation, which FlashForge says was enhanced for this model. Implementation not named[3]
Extruder
Type (direct drive / bowden) & design nameNot documentedTwo extruders[3]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented350 °C maximum extruder temperature (manufacturer claim)[3]

Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament run-out reminder[3]
Cooling & Air Handling
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedAir filter fitted; filter media not specified in the FlashForge table[3]
Electronics & Power
Input voltage (110/220 V, switch or auto)100-240 V, 50/60 Hz, 24 V 6 A[1]AC 100-240 V, 50/60 Hz[3]
Total rated power drawNot documented850 W maximum[3]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Elegoo EL3D-4.0 system. Slicer is CHITUBOX[1]Not named; slicers are Orca-Flashforge and FlashPrint 5, with OrcaSlicer listed as compatible[3]
Connectivity, UI & Camera
Display: size, type, touch?4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]7-inch touch LCD[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi, with WLAN file transfer[1]USB, Ethernet, Wi-Fi, plus cloud[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]PLA, ABS, HIPS, ASA, PETG, CoPA, PLA-CF, PETG-CF, PAHT-CF, PAHT-GF, PET-CF, PET-GF, PA12-CF, PA-CF, PA-GF, NexPA-CF25[3]
Safety

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.
