The Elegoo Mars 2 and its sibling, the Mars 2 Pro, represent the the second version in Elegoo’s highly regarded line of MSLA resin printers—delivering good print quality, faster curing, and enhanced durability compared to earlier models.
Both machines feature a 6‑inch 2K monochrome LCD, enabling dramatic reductions in layer exposure times compared to conventional RGB-type LCD screens. Bringing down exposure time to a few seconds per layer. Thanks to their COB UV LED array and optimized light engines, the Mars 2 series achieves high-resolution prints with minimal layer lines and good detail. The build volume is identical for both printers, measuring approximately 129 × 80 × 150 mm (Mars 2) and slightly taller at 160 mm for the Mars 2 Pro.
Key shared features include:
-
– Faster curing monochrome LCDs with over 2,000 hours of lifespan
-
-Solid build quality with all-metal bodies and textured sandblasted build plates for improved adhesion
-
-Simple front‑mounted USB touch-screen interfaces and support for ChituBox slicing.
However, several practical upgrades distinguish the Mars 2 Pro:
-
Air filtration system with a carbon filter and ventilation fan—a plus for reducing resin fumes, though users report filters wear out and can be difficult to replace.
-
A durable aluminum resin vat in place of the Mars 2’s plasticky version.
-
Extra Z‑axis clearance: about 10 mm more build height from a shorter bed knob (160 mm vs. 150 mm) .
-
Additional accessories included out of the box: spare FEP sheets, drip tray, and enhanced CNC-machined components.
In summary, choose the Mars 2 for a lean, cost-effective resin printing setup with fast speeds and quality output. Opt for the Mars 2 Pro if you value the carbon-filtered enclosure, robust aluminum vat, extra build height, and included extras—but be aware these are mostly convenience and durability enhancements, not performance upgrades.
