Setting up the Mars 3 Pro is a straightforward process. Here’s a step-by-step guide to help you get started:

Unboxing and Assembly

Carefully unpack the printer and ensure all the components are present. Follow the provided instructions to assemble the printer, attaching the build plate, resin vat, and cover.

Software and File Preparation

Install the Mars Pro software on your computer. This user-friendly software allows you to prepare 3D models for printing, add supports, and adjust settings. Import your STL files and position them on the virtual build plate.

Printing Materials and Settings

The Elegoo Mars 3 Pro utilizes UV-curable resins for printing. Ensure you have compatible resins and choose the appropriate settings in the software, including layer height, exposure time, and curing parameters.

IV. Printing with the Elegoo Mars 3 Pro

Now that you have your printer set up and the files ready, let’s delve into the printing process with the Mars 3 Pro:

Preparation and Calibration

Before starting a print, make sure the build plate is clean and leveled. Proper calibration ensures accurate prints and prevents adhesion issues.

Resin Printing

Pour the desired resin into the resin vat, ensuring it’s at the recommended level. The Elegoo Mars 3 Pro uses an LCD curing technology that selectively cures each layer of resin. The UV LED light source projects the layer onto the monochrome LCD, solidifying the resin. The build plate gradually rises as each layer is cured, creating the final object.

Post-Processing Techniques

Once the print is complete, carefully remove the object from the build plate using a spatula or scraper. Clean the print with isopropyl alcohol to remove excess resin. Depending on the desired finish, additional post-processing techniques such as sanding, polishing, or painting can be applied.

One crucial aspect of resin 3D printing that deserves its own focus is the wash and cure process. After your model has been printed on the Elegoo Mars 3 Pro, it’s imperative to properly clean and cure the print to ensure durability, clarity, and the desired finish.

This step involves removing any uncured resin from the surface of the print. You can use a wash and cure station, or if you don’t have one, immerse the print in a container with isopropyl alcohol (IPA) or a similar cleaning solution, gently agitating it until all the uncured resin is dissolved. This step is crucial to ensure that the print doesn’t remain tacky and to prepare it for the curing phase.


Once cleaned, the print needs to be exposed to UV light to finalize the polymerization process and harden the resin. This is done using a curing station or a UV chamber. Ensure you follow the recommended curing times based on the type of resin you’ve used. The curing process enhances the print’s mechanical properties, ensuring it’s strong and durable.

Safety Note: Always handle uncured resin and post-processed parts with gloves, and work in a well-ventilated area. Dispose of used cleaning solutions responsibly.

V. Upgrade Kit For Elegoo Mars and Elegoo Mars Pro

Upgrading your Elegoo Mars 3 Pro with ChiTu Systems’ 6.08 Inch Mono LCD Upgrade Kit can significantly enhance your 3D printing experience. Here’s what you need to know:

  • Faster Printing Speed: The mono LCD offers better UV light transmittance. This means quicker curing times for the resin, reducing the layer exposure time significantly compared to RGB LCDs. For large prints, this can save a substantial amount of time.
  • Increased Durability: The mono LCD is optimized for longer use under UV light, with a life expectancy of over 2,000 hours. This is much more compared to the 200 hours typically offered by RGB LCDs, making your printer more reliable in the long run.
  • Improved Print Quality: A better contrast ratio provided by the mono screen results in sharper details and clarity in your prints, especially beneficial for models requiring high precision.
  • Compatibility and Installation: This upgrade kit is compatible with both the Elegoo Mars and Mars Pro models.
