| 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] | QIDI Plus5, sold as "QIDI Plus5 3D Printer"[3][4] |
| Release date (announcement and actual shipping) | Not documented | Launched 5 August 2026, 09:00 EDT / 15:00 CEST[5] |
| Launch MSRP (USD) | Not documented | $749 regular launch price; a launch-window member discount put it under $700[5] |
| 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] | $749.00 for the standard model on us.qidi3d.com, checked Aug 2026. Other variants: Polar Cooler bundle $899.00, Plus5 Combo $899.00, Combo + Polar Cooler $1,049.00. No compare-at price listed[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] | Four purchase variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), and Combo + Polar Cooler. The Polar Cooler is a pre-sale add-on shipping separately, so its specs are not Plus5 specs. Replaces the Plus4 (305x305x280, 450 W + 400 W chamber)[3][5] |
| Market position: superseded? successor announced? | Not documented | Current flagship of QIDI's large-format line as of Aug 2026; sits below the Max4 (390x390x340)[3][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 211.68 x 118.37 x 220 mm[1] | 320 x 320 x 300 mm advertised — QIDI states this is about 18% more volume than the Plus4[3][4][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 327.4 x 329.2 x 548 mm[1] | 500 x 488 x 558 mm[4] |
| Net weight (kg) | Not documented | 29.0 kg net[4] |
| Frame construction & material | Metal housing with a flip-up cover and a drip guard[1] | Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[3] |
| Enclosure: open / enclosed; panel material; door/lid | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[1] | Fully enclosed, with a 3-stage air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[3][4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated, 550 W chamber heater — reported as a 37.5% increase in heater power over the Plus4 (manufacturer claim)[4][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[4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | High-precision linear rails on X[3][5] |
| Belts (type, width, e.g. Gates?) | Not documented | 1.5GT belts, 9 mm wide — wider than the 2GT 6 mm belts common in this class[3][5] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 600 mm/s (manufacturer claim)[4] |
| Max acceleration (claimed, mm/s²) | Not documented | <=20,000 mm/s2 (manufacturer claim)[4] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Resonance compensation listed as a feature; implementation not named on the product page[4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Direct drive with hardened dual gears[4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heating-plate hotend with a bimetal nozzle; 0.4 mm standard, 0.2/0.6/0.8 mm optional[4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=370 °C claimed[3][4] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=120 °C claimed, described by QIDI as an even-heating bed[3][4] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Aluminium silicone heated bed with a dual-sided textured PEI plate[4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling, plus intelligent mechanical sensor alarms[1] | Automatic levelling using an integrated load cell; QIDI describes it as direct nozzle-contact detection[4][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out sensor, plus a filament cutter[4] |

| 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 |

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.
