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. The following settings are optimized for Liqcreate resin.

*Printing with supports is advised for Wax Castable resin on the Elegoo Mars 2 and the Elegoo Mars 2 pro. This way the resin has a stronger adhesion to the build plate of the Elegoo Mars 2 and Elegoo Mars 2 pro.
** Tough-X, Flexible-X and Premium flex require heavy supports, Elastomer-X requires extra heavy supports.
*** Print with extremely thin raft to prevent adhesion issues to the platform. in the link on subject support is more information available.
