| 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] | Sovol Zero 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] | $389.00 on sovol3d.com against a $499.00 compare-at price, but marked Sold out, checked Aug 2026. Sovol's own announcement article quotes from $359.00[3][4][5] |
| 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] | No sibling variants at the time of checking. Sovol positions it against the Voron 0 and Bambu Lab P1P. Note the bed and nozzle limits are higher than the larger SV08 (120 vs 100 °C bed, 350 vs 300 °C nozzle), so SV08 figures must not be carried across[3][5][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 211.68 x 118.37 x 220 mm[1] | 152.4 x 152.4 x 152.5 mm advertised[3][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 327.4 x 329.2 x 548 mm[1] | 345 x 420 x 475 mm[3] |
| Frame construction & material | Metal housing with a flip-up cover and a drip guard[1] | Full linear rails on all axes; CoreXY with two motors sharing the moving mass[5] |
| Enclosure: open / enclosed; panel material; door/lid | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[1] | Fully enclosed[5] |
| 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[5] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rails on all axes[5] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 1200 mm/s maximum (manufacturer claim). Sovol's own material acknowledges 700 mm/s as the realistic figure for detailed prints[3][5] |
| Max acceleration (claimed, mm/s²) | Not documented | 40,000 mm/s2 maximum (manufacturer claim)[3][5] |
| Max volumetric flow claimed (mm³/s) | Not documented | <=50 mm3/s (manufacturer claim)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Planetary-gear direct-drive extruder[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heating plate. Brass or hardened-steel nozzles in 0.2/0.4/0.6/0.8/1.0 mm[3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=350 °C claimed[3][5] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass or hardened steel, buyer's choice[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=120 °C claimed; Sovol states the bed is AC-heated[3][5] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided PEI steel plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, plus intelligent mechanical sensor alarms[1] | Eddy-current scanning combined with pressure (force) sensing — Sovol describes it as an inductive sensor plus force sensor[3][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor fitted; type and location not published[3][5] |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Allwinner H616, 1 GB RAM, 8 GB eMMC, 64-bit[3] |
| PSU (brand, wattage, rail voltage) | Not documented | 150 W / 24 V (this is the DC supply; the bed is separately AC-heated per Sovol)[3][5] |
| 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] | Not named on the product page beyond OTA updates and OrcaSlicer support; Sovol markets the machine as open source[3][5] |
| 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] | Ethernet and Wi-Fi 2.4 GHz, WPA2 only (WPA3 not supported)[3][5] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera, 1920 x 1080[1] | Built-in camera for monitoring; resolution not published[3][5] |
| 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 print | Not documented | Arrives preassembled[5] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published[3][5] |
| 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] | PLA, PETG, TPU, PETG-CF, ABS, ASA, PA, PC[3] |
| 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.
