The best 3D printers aren’t the simplest gadgets, but they rank among the coolest. The best printers can produce outrageously complex objects and are getting more impressive by the year. But to ensure your printer is operating as well as it possibly can, you must keep it up to date. Below, we’ll explain all you need to know about how to update 3D printer firmware.


  • Firmware is specific software that controls a 3D printer’s mechanical movements and other critical functions like temperature control.
  • There are a handful of firmware types, each with unique advantages, such as faster printing speeds.
  • Updating the Firmware requires a user to download the file from the provider, upload it to the 3D printer software program, and then transfer it to the 3D printer.

Insider Tip

Different firmware types come with their specific benefits. For example, Klipper firmware helps to achieve faster print speed.

How to Update Firmware on a 3D Printer

To put it simply, Firmware is a specific program that controls the printer’s mechanical movements. And if you’ve ever seen 3D printers at work, you know a lot of activity is going on. Therefore, keeping the Firmware up to date helps the motors function at peak capacity and ultimately helps lower the print time and increase print precision. Although, if you’re interested in how to program a 3D printer, we have another guide for you.

There are a handful of 3D firmware types, the most common being Marlin, Klipper, RepRap, and Repetier. Each type has its unique properties and methods for updating, but there are some general guidelines across all types that we’ve outlined below.

If you finish this and feel the need to tech out a bit more, feel free to continue your reading with our guide on how to program a 3D printer.

STEP 1 Download the Latest Firmware

Go to your firmware service provider’s website and download the latest version. Sometimes, the service providers will have the version stored in GitHub.

STEP 2 Upload Firmware to Printer Software

Go into your 3D printer’s software platform and upload the new firmware file to your computer. This usually requires some form of verification process to compile the latest Firmware version.

STEP 3 Upload Firmware Update to Printer and Verify

Connect your 3D printer to your computer via a USB cable or wireless connection. Then, navigate to the option that uploads the new file. Wait for the file to upload, then restart your printer.


Some of your customized settings, like bed leveling and calibration, may reset when updating the printer firmware. Always check the settings to verify before running your next print.

STAT: About 80% of printers use marlin firmware. (source)
