| 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 U1 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] | $849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked 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] | An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 211.68 x 118.37 x 220 mm[1] | 270 x 270 x 270 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 327.4 x 329.2 x 548 mm[1] | 584 x 499 x 730 mm[3] |
| Net weight (kg) | Not documented | 18.2 kg[3] |
| Frame construction & material | Metal housing with a flip-up cover and a drip guard[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[1] | Open as sold; a top cover is an optional accessory that raises the supported material range[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] | Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 500 mm/s maximum toolhead speed (manufacturer claim)[3] |
| Max acceleration (claimed, mm/s²) | Not documented | 20,000 mm/s2 maximum (manufacturer claim)[3] |
| Max volumetric flow claimed (mm³/s) | Not documented | 32 mm3/s maximum hotend flow (manufacturer claim)[3] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input shaping with an accelerometer, run as a calibration routine[3] |
| Extrusion Pressure Control | ||
| Pressure advance (Klipper) / linear advance (Marlin) supported? | Not documented | Pressure advance, with automatic flow compensation calibration[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 300 °C maximum (manufacturer claim)[3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Stainless steel as standard; hardened steel needed for fibre-filled grades[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 100 °C maximum (manufacturer claim)[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Flexible steel sheet with a PEI surface[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, plus intelligent mechanical sensor alarms[1] | Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out detection, plus air-printing detection and RFID filament recognition[3] |
| Multi-material/multi-color capability or official upgrade path | Not documented | Four toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Main plus auxiliary part-cooling fans[3] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 V, 50/60 Hz, 24 V 6 A[1] | Not documented |
| Total rated power draw | Not documented | Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[3] |
| 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] | 3.5-inch, 320 x 480 touchscreen[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi, with WLAN file transfer[1] | Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera, 1920 x 1080[1] | 2 MP built-in chamber camera for live view[3] |
| Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it? | AI camera with print-failure detection[1] | Not documented |
| 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] |
| 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] | Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[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.
