The Elegoo Mars is a first‑generation MSLA resin 3D‑printer equipped with a 405 nm UV light source and an early RGB‑LCD panel. Due to its low optical output compared to modern monochrome LCD, COB‑LED and DLP systems, the Mars requires longer exposure times to achieve sufficient cure depth and layer adhesion. Despite its age, the platform remains compatible with a wide range of Liqcreate engineering, dental and general‑purpose resins when using validated exposure parameters. This page provides validated Liqcreate resin settings for the Elegoo Mars.
Within the Elegoo Mars‑series, the original Mars shares its general workflow and resin behavior with later models such as the Elegoo Mars 2 and Elegoo Mars 3, although each generation uses a different LCD type and optical engine. You can navigate between these printers and their validated Liqcreate resin settings using the links below.
For a complete overview of all Liqcreate materials, exposure parameters and cross‑printer compatibility, visit the Liqcreate resin parameter database. If you require assistance with exposure tuning, resin selection or workflow optimization for the Elegoo Mars, our engineering team is available through the Liqcreate support page.
Elegoo Mars resin 3D‑printing parameters
The exposure settings listed below are validated for the Elegoo Mars and optimized for its low‑power RGB‑LCD light engine. Due to the limited irradiance of this early MSLA platform, most materials require longer exposure times and extended base‑layer curing to ensure reliable adhesion and dimensional stability. Use these parameters as validated profiles or as a baseline when tuning additional Liqcreate materials.

About the Elegoo Mars and Elegoo Mars Pro resin 3D‑printers
The Elegoo Mars and Mars Pro are early‑generation MSLA resin 3D‑printers that helped popularize consumer‑grade resin printing. Both systems use a 405 nm UV light source and an RGB‑LCD panel, resulting in longer exposure times compared to modern monochrome LCD and DLP‑based printers. The Mars Pro introduced incremental improvements such as a modified light engine, activated carbon filtration and minor mechanical refinements, but both platforms share similar resin behavior and exposure characteristics.
