The Elegoo Mars 2 and Mars 2 Pro represent the second generation in Elegoo’s well‑known MSLA printer lineup, offering fast curing performance, stable optical output and reliable print quality for engineering parts, dental models and general‑purpose prototyping. Both printers use a 6‑inch 2K monochrome LCD with high UV transmission, enabling significantly shorter exposure times compared to older RGB‑based systems. Combined with a COB‑LED light engine, the Mars 2 series delivers uniform irradiance across the build area, resulting in predictable cure depth, consistent dimensional accuracy and clean surface detail when using Liqcreate 405 nm resins. Both printers require exposure settings tailored to their 2K monochrome LCD, ensuring controlled cure depth and consistent layer adhesion across all Liqcreate materials.
Because the Mars 2 and Mars 2 Pro share the same optical architecture, resin settings transfer seamlessly between both machines with only minor adjustments for build height and airflow differences. Users working with multiple Elegoo printers will find that the exposure behavior of the Mars 2 series aligns closely with newer systems such as the Elegoo Mars 3, while also sharing several light‑engine characteristics with larger platforms like the Elegoo Saturn 4 Ultra. This makes the Mars 2 series a stable reference point within the broader Elegoo ecosystem. For users transitioning to higher‑resolution systems, the Elegoo Mars 3 resin settings page provides a useful comparison baseline.
This page provides complete Elegoo Mars 2 and Mars 2 Pro resin settings, including validated exposure times, lift parameters, bottom layer behavior, light‑off delays and recommended support strategies for all tested Liqcreate materials. For a broader overview of compatible printers and materials, you can explore the full resin setting database, which includes baseline parameters for nearly all monochrome MSLA printers.

*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.
About the Elegoo Mars 2 and Mars 2 Pro resin 3D‑printers
The Elegoo Mars 2 and Mars 2 Pro are second‑generation MSLA printers built around a 6‑inch 2K monochrome LCD and a COB‑LED light engine, providing fast exposure performance and stable optical output for consistent resin curing. Both machines share nearly identical imaging behavior, meaning resin settings transfer reliably between them with only minor adjustments for build height and airflow differences. Their combination of uniform irradiance, high UV transmission and predictable cure depth makes the Mars 2 series a dependable platform for Liqcreate engineering, dental and modeling materials.

Specifications of the Elegoo Mars 2 Pro resin 3D‑printer
The Elegoo Mars 2 Pro builds on the core architecture of the Mars 2 platform with several hardware refinements that improve durability, stability and long‑term usability. While print performance and exposure behavior remain identical to the standard Mars 2—thanks to the shared 2K monochrome LCD and COB‑LED light engine—the Pro model introduces a sturdier aluminum resin vat, an integrated carbon‑filter ventilation system and slightly increased Z‑axis height. These enhancements make the Mars 2 Pro a more robust and user‑friendly machine without altering the resin settings required for accurate curing and dimensional consistency.

FAQ — Elegoo Mars 2 / Mars 2 Pro resin settings & printer comparison
1. How do the Elegoo Mars 2 and Mars 2 Pro differ in printing performance? Both printers produce identical curing behavior because they share the same light source and LCD technology. The Mars 2 Pro only adds hardware refinements—such as a metal vat, carbon filtration and slightly increased Z‑height—which improve usability but do not affect resin exposure requirements.
2. Are Mars 2 resin settings directly compatible with the Mars 2 Pro? Yes. All Liqcreate settings transfer seamlessly between both machines. Only very tall models may benefit from a minor lift‑speed adjustment due to the Mars 2 Pro’s extended Z‑axis.
3. How does the Mars 2 series compare to newer printers like the Elegoo Mars 3? The Mars 3 uses a higher‑resolution LCD and a more efficient light engine, enabling shorter exposure times and finer detail reproduction. Mars 2 settings can serve as a starting point, but the Mars 3 typically requires more precise tuning of off‑delay and exposure duration.
4. Can all Liqcreate resins be used on the Mars 2 and Mars 2 Pro? Yes. Both printers are fully compatible with the entire Liqcreate 405 nm portfolio, including engineering, dental, flexible and specialty materials. Some resins—such as Tough‑X, Flexible‑X and Elastomer‑X—require reinforced support structures for optimal adhesion.
5. Why do some resins need different exposure values on the Mars 2 series compared to other Elegoo printers? Exposure requirements depend on each printer’s optical characteristics, including UV transmission, pixel size and irradiance distribution. Because the Mars 2 series uses a specific 2K monochrome LCD and light profile, certain materials may cure differently than on higher‑resolution or higher‑output Elegoo systems. Printer‑specific settings ensure consistent accuracy and reliable layer bonding.
