| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Mars 5 Ultra. Elegoo's product handle is mars-5-ultra-9k-7inch-monochrome-lcd-resin-3d-printer[1][2][3] | 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[4][5] |
| Street price (USD; dated snapshot per entry) | $269.00 in Elegoo's live US product feed, in stock, checked Aug 2026. The Mars 5 Series collection page rendered $259.00 against a $338.00 compare-at price on the same day, so the two Elegoo surfaces disagree by $10[3][2] | $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)[5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Not a trim of the Mars 5 — a different imaging stack and a different release mechanism: 7-inch 9K LCD and 18 um pixels vs 6.6-inch 4K and 35 um, 150 vs 70 mm/h, tilt-release vs straight lift, an AI camera, and Wi-Fi added. Seven bundle SKUs pair it with Mercury Plus V2.0/V3.0 or Mercury XS at $363-$432[6][1][2][3] | 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[4][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 153.36 x 77.76 x 165 mm[1] | 211.68 x 118.37 x 220 mm[4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 260 x 268 x 451.5 mm[1] | 327.4 x 329.2 x 548 mm[4] |
| Net weight (kg) | Approximately 8.8 kg[1] | Not documented |
| Frame construction & material | Not documented | Metal housing with a flip-up cover and a drip guard[4] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a removable UV-blocking cover[1] | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | MSLA with tilt-release: the resin tank tilts after each layer to peel the part rather than pulling straight up. Single Z axis[1] | 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[4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, one click, via an intelligent mechanical sensor. One-Click Self-Check routine. Alarms for resin shortage, residue detection and levelling failure[1] | Automatic levelling, plus intelligent mechanical sensor alarms[4] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 V, 50/60 Hz, 24 V 3 A[1] | 100-240 V, 50/60 Hz, 24 V 6 A[4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named by Elegoo. Supported slicer is CHITUBOX[1] | Elegoo EL3D-4.0 system. Slicer is CHITUBOX[4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1] | 4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | USB and Wi-Fi, with WLAN file transfer[4] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | AI camera fitted; Elegoo does not publish its resolution for this model[1] | AI camera, 1920 x 1080[4] |
| Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it? | AI camera detects empty build plates and print errors[1] | AI camera with print-failure detection[4] |
| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin. No compatibility list published on this listing[1] | 405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[4] |
| Safety | ||
| Firmware safety limits (max temp cutoffs — exact values) | Overheating protection activates above 80 °C[1] | Not documented |
| Resin & MSLA | ||
| Masking LCD | 7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[1][3] | 10-inch 16K monochrome masking LCD, 15120 x 6230 px, XY pixel pitch 14 x 19 um (manufacturer specification)[4][5] |
| Light source | 25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[1] | COB light source with a Fresnel collimating lens[4] |
| Light uniformity & intensity | 92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[1] | 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[4] |
| Vertical print speedmm/h | 150 mm/h maximum, which Elegoo attributes to the tilt-release mechanism (manufacturer claim). Elegoo also offers switchable slow and fast print modes but does not state the layer height the figure assumes[1] | Up to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[4] |
| Layer exposure times | 1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[1] | Not documented |
| Release film | Not documented | PFA release film. No rated life published[4] |
| LCD life & replaceability | Masking LCD protected by a scratch-resistant tempered 9H glass cover that also guards against resin leakage. Elegoo publishes no rated screen life in hours and does not state whether the user can replace the LCD[1] | Masking LCD shielded by tempered 9H protective glass. Elegoo publishes no rated screen life in hours and does not state user replaceability[4] |
| Resin vat & feeding | Resin tank supplied with the machine; resin-shortage and residue-detection alarms fitted. Capacity not published; no auto-refill[1] | 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[4] |
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.
