Elegoo is manufacturing and developing resin 3D-printers since 2017. With the release of the Elegoo Mars it was competing for the entry-level resin 3D-printing market with competitors like Anycubic, Phrozen3D, and many others. With Elegoo pushing the prices further down and has entry models like the Elegoo Mars C even below $200. Today it has expanded its offering with monochrome 2K & 4K LCD screens and bigger build plates, like the Elegoo Saturn. With the release of the Mars 3, Elegoo is following the steps of Phrozen as the Mars 3 is similar to the Phrozen Sonic Mini 4K. A small 4K resin 3D-printer with high resolution (35 micron pixel size). 3D-printing parameters for Liqcreate resins on the Elegoo Mars 3 can be found here.
What are the differences between the different Elegoo resin 3D-printers?
There are some differences between the 3D-printers of Elegoo. To start with, their Mars and Mars Pro printers are from the first generation and are equipped with a 2K RGB screen, meaning that the print speed is slower. The Mars 2, Mars 2 Pro and Saturn have a new Monochrone LCD screen, increasing the print speed by factor 2-4 and also increasing the lifetime of the LCD screen. When purchasing a new entry-model resin based 3D-printer, we would always advise to choose a 3dprinter with a monochrome LCD screen. It is quite difficult to find big differences between the Mars 2 and the Mars 2 Pro. Both have the same single guided z-axis and a 2K monochrome screen with similar pixel sizes, build area and print speed. Looking at their website and reviews, the two major differences would be that you will get a metal resin tank with the Pro version. And the Elegoo Mars 2 Pro version has an active carbon filter, reducing resin smell. Most of the Liqcreate resins have no odor, therefor we do not see the value of the Mars 2 Pro compared to the Mars 2. With the new Mars 3, it Elegoo is launching a small 4K resin 3D-printer with incredible small pixel size, supporting extremely accurate models to be printed.
