ELEGOO Mars 5 Ultra vs Phrozen Sonic Mini 8K S — documented properties and sources

ClassRESINRESIN
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]Phrozen Sonic Mini 8K S 7.1" LCD 3D Printer. Manufacturer number 51010040501102[4][5][6]
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]$270.00 on us.phrozen3d.com, backordered with an end-of-September ETA, checked Aug 2026. The collection page rendered it as unavailable on the same day[6][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[7][1][2][3]Phrozen's 7.1-inch line is easy to confuse: the Sonic Mini 8K S ($270) sits beside the older Sonic Mini 8K ($340, sold out) and the 5.5-inch Sonic Mini ($129.99). The 10.1-inch Sonic Mighty family is a different size class entirely. The 8K S is the only one of the group with a single linear rail and a lead screw rather than a ball screw[5][4][6][8]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable153.36 x 77.76 x 165 mm[1]165 x 72 x 170 mm[4][6]
Machine footprint (mm) & clearance needed (cable/spool overhang)260 x 268 x 451.5 mm[1]290 x 290 x 430 mm[4][6]
Net weight (kg)Approximately 8.8 kg[1]10 kg[4][6]
Frame construction & materialNot documentedBlack textured housing with a neon-green plastic cover[4]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a removable UV-blocking cover[1]Open-frame MSLA with a UV-blocking plastic 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, single Z axis on one linear rail with a lead screw, straight-lift peel[4][6]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedOne linear rail; lead screw (not a ball screw)[4][6]
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]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)100-240 V, 50/60 Hz, 24 V 3 A[1]24 V DC, 2 A[6]
Total rated power drawNot documented48 W maximum system power[6]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named by Elegoo. Supported slicer is CHITUBOX[1]Not named by Phrozen. Native file format .PRZ; compatible slicers CHITUBOX, Lychee and VoxelDance Tango[4][6]
Connectivity, UI & Camera
Display: size, type, touch?4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[1]3.5-inch touch panel (control panel — not the masking LCD, see W1)[6]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi[1]USB only[4][6]
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]Not documented
Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it?AI camera detects empty build plates and print errors[1]Not documented
Materials Support
Officially supported filament list405 nm photopolymer resin. No compatibility list published on this listing[1]405 nm photopolymer resin; 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 LCD7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[1][3]7.1-inch 8K monochrome masking LCD, XY pixel pitch 22 um. Phrozen does not publish the pixel count for this model[4][6]
Light source25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[1]Linear projection LED module. Wavelength not published for this model[4][6]
Light uniformity & intensity92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[1]Not documented
Vertical print speedmm/h150 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]Max 80 mm/h (manufacturer claim). Phrozen does not state the layer height or resin type the figure assumes[6]
Layer exposure times1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[1]Not documented
Layer height rangeNot documented0.01-0.30 mm[6]
Release filmNot documentedFEP film — note this is plain FEP, whereas the Sonic Mighty Revo 14K ships nFEP. No rated life published[6][8]
LCD life & replaceabilityMasking 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]Not documented
Resin vat & feedingResin tank supplied with the machine; resin-shortage and residue-detection alarms fitted. 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.
