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]UniFormation GKtwo 10.3" 8K Resin Printer[4][5]
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]$749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[4]
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][6][2][3]UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable143.43 x 89.6 x 150 mm[1]228 x 128 x 245 mm[4][5]
Machine footprint (mm) & clearance needed (cable/spool overhang)230 x 230 x 433.5 mm[1]350 x 315 x 455 mm[4][5]
Net weight (kg)Approximately 6.6 kg[1]20 kg packaged (UniFormation publishes package weight, not net weight)[4][5]
Frame construction & materialMetal frame with adjustable foot pads[1]Not documented
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a removable UV-blocking cover[1]Open-frame MSLA with a UV-blocking cover[4][5]
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][6]MSLA — photocuring LCD, single Z axis, straight-lift peel[4][5]
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]110/220 V[4][5]
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. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[4][5]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[1]5-inch touchscreen (control panel — not the masking LCD, see W1)[4][5]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB only — no Wi-Fi on this model[1]USB file transfer[4][5]
Materials Support
Officially supported filament list405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[1]402.5-405 nm photopolymer resin. No closed compatibility list published[4][5]
Safety
Firmware safety limits (max temp cutoffs — exact values)Intelligent overheating protection stops printing above 80 °C[1]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedPrinting tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[4]
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]10.3-inch masking LCD, 7680 x 4320 px (8K), XY pixel pitch 29.6 um (manufacturer specification)[4][5]
Light sourceCOB LED at 405 nm. Elegoo does not publish an LED count or collimating optics for this model[1]Photocuring LCD light engine at 402.5-405 nm. UniFormation does not publish the LED count or optical design on this page[4][5]
Vertical print speedmm/h70 mm/h maximum (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[1]Not documented
Layer exposure timesNot documented2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[4][5]
Layer height rangeNot documented0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[4][5]
Release filmPFA film with a non-stick surface. No rated life published[1]Not documented
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]Resin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[4][5]
Fume extractionNone fitted. Elegoo states compatibility with the separately sold MARS MATE air purifier for odour reduction[1]Built-in odour filter[4][5]

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.
