How to Update Elegoo Saturn Firmware

A particularly important piece of equipment that has risen in fame over the years, especially among digital designers and manufacturing industries, is the 3D printer.

With its ability to create three-dimensional objects of different and complex shapes and sizes from a digital file and with even lesser materials than would have been required in the traditional manufacturing process, it is no wonder most people interested in creative design have also opted to purchase 3D printers for their own personal use.

However, as there are several kinds of 3D printer manufacturers, it is only fair that you make the right move by purchasing one that I best suited to your needs in all ramifications, and this is none other than the Elegoo Saturn.

What Is Elegoo Saturn?

The Elegoo Saturn is a larger-than-average resin 3D printer that boasts a 4K resolution monochrome screen and a 192 x 120 x 200 mm print volume. With it being considerably larger than previous versions, the Elegoo Saturn has an internal monochrome LCD with 3840 x 2400 pixels in the printable area to give an XY-axis printing resolution of 50 microns.

It is able to cure liquid resin into solid objects with its monochrome LCD which acts as a light mask for each layer of curing, allowing a greater intensity of light to pass through. With this feature, the Elegoo Saturn is about 60% faster than similar, non-mono printers since the light-on time for each layer can be as little as 1-2 seconds.

It is the added advantages of it being of great budget and having a large print volume, fast printing speed, and great detail that make it highly desirable by consumers, so much so that upon its availability the first wave of printers shipped out was immediately carted off the market by eager buyers until occasional batches every now and then became the norm.

How Do You Update the Elegoo Saturn Firmware?

There are two major steps to take when attempting to update your Elegoo Saturn Firmware and they are:

  • Identifying Your Version: This is the first and most crucial step as the Elegoo Saturn has three different types of LCD screens so you have to be sure of your version in order to download the latest one and make the update. There are three ways to identify your Elegoo Saturn version, the first being by checking the number on the bottom of your machine. Secondly, you can open the side cover and take a picture of the screen cable, and lastly, you can check the version number of your own machine.
  • Downloading and Updating: To download the new firmware, you can click here. Once this is done, you can proceed to update the firmware by doing the following in this exact order: update the files in the firmware file and copy the files to the root directory of the USB flash drive, insert the USB flash drive into the printer, and print the files on the printer to update. The LCD file will then be automatically updated after restarting the machine in the shutdown state, so don’t update repeatedly to avoid being prompted *Same Firmware already exists!*

Why Should You Update Elegoo Saturn Firmware?

You might be left wondering why you need to update your Elegoo Saturn firmware especially if the purchase is still fairly new, however, if you’ve been using the product for a while, an update is inevitable for continuous smooth use of it.

Since Elegoo Saturn has a monochrome screen and these types of screens are known to have an approximate lifetime of 2,000 hours of operation before the exposure to UV light deteriorates the pixels causing your prints to get messier and less accurate, an update is necessary.

Due to this shortcoming, you’ll need to replace the printer’s LCD, and you can also replace other wear and tear parts like the FEP foil, with the help of the detailed tutorial videos and instructions provided by Elegoo.

Also, because of the different screen versions compatible with the Elegoo Saturn, you might need to flush the printer’s firmware depending on the screen version you choose.


Updating your Elegoo Saturn firmware is a simple feat that can be achieved if you follow the proper instructions and are patient enough to do so. Getting your firmware updated will enable you to fully maximize your Elegoo Saturn to its fullest and best version so do not wait until it is too late.
