ClassRESINRESIN
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]Formlabs Form 4 3D 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]Starting at $2,625.00 at GoEngineer, in stock, checked Aug 2026. Formlabs sells the printer as part of packages (Form 4 Complete Package etc.), so package prices are much higher than the printer-only figure[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][6][2][3]Three machines share this platform and are constantly conflated. Form 4: 200 x 125 x 210 mm, 50 um pixels, 18.3 kg, 480 W, one resin cartridge, NOT biocompatible. Form 4B: identical hardware but validated for 38 Formlabs materials including 15 biocompatible. Form 4L: 353 x 196 x 350 mm, 46 um pixels, 58.5 kg, 900 W, two cartridges[4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable143.43 x 89.6 x 150 mm[1]200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[4][5]
Machine footprint (mm) & clearance needed (cable/spool overhang)230 x 230 x 433.5 mm[1]398 x 367 x 554 mm[4][5]
Net weight (kg)Approximately 6.6 kg[1]18.3 kg[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]Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[4]
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]Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; 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]100-240 VAC, 4.8 A, 50/60 Hz, 480 W[4]
Total rated power drawNot documented480 W[4]
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]Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[5]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch resistive touchscreen (control panel — not the masking LCD, see W1)[1]7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB only — no Wi-Fi on this model[1]Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[4][5]
Materials Support
Officially supported filament list405 nm photopolymer resin. Elegoo does not publish a resin compatibility list on this listing[1]Formlabs resins across rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic and castable families. Biocompatible resins require the Form 4B, not the Form 4[4]
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 documentedXY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[4][5]
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]Low Force Display masking LCD with a 50 um pixel size and pre-tuned anti-aliasing. Formlabs does not publish the screen diagonal or pixel count[4][5]
Light sourceCOB LED at 405 nm. Elegoo does not publish an LED count or collimating optics for this model[1]Backlight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[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]Maximum 100 mm/h; average 40 mm/h at a 100 um layer height (manufacturer figures — GoEngineer publishes both, which is unusually explicit about the basis). Formlabs separately claims most prints finish in under 2 hours[5][4]
Layer height rangeNot documented25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[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]Single next-generation resin cartridge; Formlabs claims 5-10x faster filling and 63% less waste. Resin tank rated for 75,000+ layers with any Formlabs material. No vat capacity published[4][5]
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.
