Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Mars 5. Elegoo's own product handle spells the configuration out: mars-5-4k-6-6inch-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)$179.00 on us.elegoo.com against a $225.00 compare-at price (20% off), in stock, checked Aug 2026. The live product feed shows the same $179.00[2][3]$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)Sold beside the Mars 5 Ultra, which is a materially different machine: 7-inch 9K masking LCD vs 6.6-inch 4K, 18 um vs 35 um pixels, 150 vs 70 mm/h, a 4.0-inch capacitive control screen vs 3.5-inch resistive, and Wi-Fi (the plain Mars 5 is USB only). Elegoo lists ten further Mars 5 / Mars 5 Ultra bundle SKUs pairing the printers with Mercury wash-and-cure stations at $302-$432; those are not printer prices[1][7][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]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)MSLA — UV LCD masked stereolithography. Single Z axis, build plate lifting straight out of the vat (no tilt-release on this model, unlike the Mars 5 Ultra)[1][7]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]
Heated Bed & Surface
Bed surface (material, texture, coating), single/double-sidedLaser-engraved build plate with a quick-release design[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic levelling, one click. An intelligent mechanical sensor detects resin residue to prevent LCD damage[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 slicers are Voxeldance Tango and CHITUBOX; STL and OBJ accepted[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?3.5-inch resistive 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 only — no Wi-Fi on this model[1]USB only[4][6]
Materials Support
Officially supported filament list405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[1]405 nm photopolymer resin; no closed compatibility list published[4]
Safety
Firmware safety limits (max temp cutoffs — exact values)Intelligent overheating protection stops printing above 80 °C[1]Not documented
Resin & MSLA
Masking LCD6.6-inch 4K monochrome masking LCD, 4098 x 2560 px, XY pixel pitch 35 x 35 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 sourceCOB LED at 405 nm. Elegoo does not publish an LED count or collimating optics for this model[1]Linear projection LED module. Wavelength not published for this model[4][6]
Vertical print speedmm/h70 mm/h maximum (manufacturer claim). Elegoo does not state the layer height or resin type 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 height rangeNot documented0.01-0.30 mm[6]
Release filmPFA film with a non-stick surface. No rated life published[1]FEP film — note this is plain FEP, whereas the Sonic Mighty Revo 14K ships nFEP. No rated life published[6][8]
Resin vat & feedingReplaceable resin tank with two pouring openings and screw caps. An intelligent mechanical sensor detects resin residue in the vat. Capacity not published; no auto-refill[1]Not documented
Fume extractionNone fitted. Elegoo states compatibility with the separately sold MARS MATE air purifier for odour reduction[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.
