The Elegoo Mars 4 is a 9K MSLA resin 3D‑printer equipped with a 405 nm UV light source and a high‑transmittance 7‑inch monochrome LCD. Compared to earlier Mars‑series printers, the Mars 4 offers a significant increase in pixel density, delivering an 8520 × 4320 resolution and an 18 × 18 µm XY accuracy. This enables sharp surface detail, predictable curing behavior and broad compatibility with Liqcreate engineering, dental and general‑purpose resins. For a complete overview of all Liqcreate materials and cross‑printer compatibility, visit the Liqcreate resin parameter database.
With a build volume of 153.36 × 77.76 × 175 mm and a redesigned optical engine, the Mars 4 provides uniform irradiance across the platform, resulting in stable layer stacking and consistent dimensional performance. This page provides validated Liqcreate resin settings for the Elegoo Mars 4 (basic), including exposure times, lift parameters and workflow notes for reliable MSLA printing. You can download the validated Chitubox settings for the Elegoo Mars 4 here.
The Elegoo Mars 4 series includes four different printers: the Mars 4 (basic), Mars 4 DLP, Mars 4 Ultra 9K and Mars 4 Max. You can also view resin settings for the Elegoo Mars 4 DLP, Elegoo Mars 4 Ultra 9K and Elegoo Mars 4 Max. If you need assistance with Liqcreate resin compatibility or Elegoo Mars 4 parameters, our engineering team is available through the Liqcreate support page.

All exposure profiles for the Elegoo Mars 4 were validated using standard Liqcreate workflows. All profiles used 8 transition layers unless otherwise specified. Tough‑X, Flexible‑X and Premium Flex require heavy supports, while Elastomer‑X requires extra heavy supports due to its mechanical behavior.
About the Elegoo Mars 4 resin 3D‑printer
The Elegoo Mars 4 is built around a 7‑inch 9K monochrome LCD and a uniform UV LED matrix, providing high pixel density, strong irradiance and predictable curing behavior across the entire build area. Its stable Z‑axis mechanics and rigid frame contribute to consistent layer stacking, making the Mars 4 suitable for detailed models, engineering parts and functional prototypes. These characteristics ensure reliable performance with Liqcreate engineering, dental and general‑purpose resins when using validated exposure parameters.
