| 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] | LulzBot TAZ Pro Long Bed 3D Printer[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] | $7,995.00 at MatterHackers, listed as currently unavailable, 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] | Not simply a longer TAZ Pro. The Long Bed ships the Asteroid 285 tool head with a 1.2 mm nozzle, a 0.3-0.9 mm equipped layer range, an 80 °C bed cap (vs 110 °C), 150 mm/s travel (vs 300) and BLTouch 32-point mesh levelling (vs 4-point contact). Bed material also differs: blue spring-steel magnetic flex rather than glass with PEI film[3][4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 211.68 x 118.37 x 220 mm[1] | 282 x 582 x 285 mm[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] | Open frame; GT2 belt drive with Igus SST rods and polymer bushings[3] |
| Enclosure: open / enclosed; panel material; door/lid | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[1] | Open frame, no enclosure[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] | Cartesian bedslinger[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic TMC2130[3] |
| Speed & Acceleration | ||
| Max travel speed | Not documented | 150 mm/s maximum travel speed, firmware-limited[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Asteroid 285 tool head[3] |
| Filament diameter | Not documented | 2.85 mm standard, 1.75 mm optional[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 290 °C maximum, firmware-limited[3] |
| Stock nozzle size & sizes included in box | Not documented | 1.2 mm GammaMaster steel[3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | GammaMaster steel[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 80 °C maximum bed temperature — notably lower than the base TAZ Pro[3] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 360 W, 24 V silicone bed heater[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Blue spring-steel magnetic flex bed system[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, plus intelligent mechanical sensor alarms[1] | BLTouch, 32-point automatic mesh calibration[3] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 32 points[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor with runout and stripping detection[3] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | 32-bit Archim 2.2b with Trinamic TMC2130 drivers[3] |
| PSU (brand, wattage, rail voltage) | Not documented | 500 W 24 V Mean Well, auto-switching, 100-240 VAC input[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] | Marlin[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] | USB serial; 16 GB flash drive included for standalone printing[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 list | 405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[1] | PLA, TPU, ABS, PETG, PVA, PVB, nylon, PC and other materials below 290 °C[3] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1 year standard with extended options. Made in the USA[3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Positional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification)[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.
