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]Snapmaker J1S High Speed IDEX 3D Printer[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]$1,399.00 at MatterHackers, listed as currently unavailable with a pre-order option quoting roughly 5 weeks, 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]The J1s differs from the original J1 by an additional part-cooling fan. Usable volume depends on the print mode: 300 x 200 x 200 mm in default and backup modes, 160 x 200 x 200 in copy mode, 150 x 200 x 200 in mirror mode[3][4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable211.68 x 118.37 x 220 mm[1]300 x 200 x 200 mm in default and backup modes[3]
Machine footprint (mm) & clearance needed (cable/spool overhang)327.4 x 329.2 x 548 mm[1]539 x 401 x 464 mm[3]
Net weight (kg)Not documented25 kg net[3]
Frame construction & materialMetal housing with a flip-up cover and a drip guard[1]Aluminium-alloy frame with one-piece die casting and linear rails; Snapmaker quotes rail repeatability of +/-0.03 mm in X/Y and +/-0.02 mm in Z[4]
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]IDEX — two independently driven extruders[3][4]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedLinear rails[4]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented350 mm/s maximum (manufacturer claim)[4]
Max acceleration (claimed, mm/s²)Not documented10,000 mm/s2 maximum (manufacturer claim)[4]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented300 °C maximum (manufacturer claim)[3][4]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented100 °C maximum (manufacturer claim)[3]
Bed surface (material, texture, coating), single/double-sidedNot documentedCustom dual-sided PEI glass plate: glossy glass on one face, PEI coating on the other[3][4]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic levelling, plus intelligent mechanical sensor alarms[1]3-point bed levelling, which Snapmaker contrasts with 9-16 point systems; assisted calibration quoted at about 10 minutes[4]
Electronics & Power
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documented1 GB RAM, 8 GB eMMC; the 5-inch display runs Android[3]
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, 4.4 A max input; DC 24 V, 400 W max output[3]
Total rated power drawNot documented400 W maximum output[3]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Elegoo EL3D-4.0 system. Slicer is CHITUBOX[1]Not named by Snapmaker; the supplied slicer is Luban, with third-party software supported[3]
Connectivity, UI & Camera
Display: size, type, touch?4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]5-inch Android display, 1280 x 720[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi, with WLAN file transfer[1]Wi-Fi, USB cable, USB flash drive[3]
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
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, PC, TPU, TPE, PETG, ASA, PP, PVA, PA, PA-GF, PA-CF[3]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedLess than 50 dBA claimed by the manufacturer. No independent measurement; distance and method not stated[3]
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.
