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 X-Max 3, listed by QIDI as "Qidi Tech X-Max 3 3D Printer" and in navigation as X-Max3[3][4]
Release date (announcement and actual shipping)Not documentedNot published by QIDI; the product page carries a discontinuation notice rather than a launch date (checked Aug 2026)[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]$899.00 (from a $999.00 sale reference) on us.qidi3d.com but marked Sold Out and discontinued, checked Aug 2026. 3D Printers Online Store lists $1,099 USD, also out of stock[3][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]Same-generation siblings X-Plus 3 (280x280x270, 500 mm/s, 800 W) and X-Smart 3 (175x180x170, no chamber heating, 300 °C, 350 W). All three share the Cortex-A53 1.5 GHz / 1 GB DDR3 / 8 GB eMMC control board, so shared-board specs are not evidence of shared print specs. Replaced by the Max4[4][6][7][8]
Market position: superseded? successor announced?Not documentedDiscontinued and out of production; QIDI directs buyers to the Max4[3]

Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C maximum, independent chamber heating (manufacturer claim)[3][4]
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 documentedLinear optical axis (polished steel rod) of high-strength steel[4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedDouble Z axis[4]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented<=600 mm/s (manufacturer claim)[3][4][5]
Max acceleration (claimed, mm/s²)Not documented20,000 mm/s2 (manufacturer claim)[3]
Max volumetric flow claimed (mm³/s)Not documented35 mm3/s extruder flow (manufacturer claim)[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedHigh-flow direct-drive extruder; QIDI states a 9.5:1 gear ratio for this model[3][4]
Gear ratio & drive gear materialNot documented9.5:1[3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedCeramic heating core. Two interchangeable nozzle-head sets shipped: copper alloy for standard materials, hardened steel for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[3][4]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented<=350 °C claimed[3][4][5]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented<=120 °C claimed[4][5]

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 via Klipper adaptive meshing; probe technology not named by QIDI[3]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament detection fitted; type and location not published[4]
Cooling & Air Handling
Auxiliary part-cooling fan?Not documentedAdditional (auxiliary) cooling fan fitted[4]
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedChamber circulation blower with activated-carbon air filter[4]

Light sourceCOB light source with a Fresnel collimating lens[1]Not documented
Light uniformity & intensityLight 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/hUp to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[1]Not documented
Release filmPFA release film. No rated life published[1]Not documented
LCD life & replaceabilityMasking 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 & feedingReplaceable 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.
