What is 3D Printer Firmware and Why It Matters
When it comes to 3D printing, firmware is a crucial yet often overlooked component that plays a major role in determining how well your printer performs. Essentially, 3D printer firmware is the software that runs on the printer's mainboard, acting as the brain of the machine by translating design files (G-code) into physical movements that control the printer’s motors, extruder, and other components. The right firmware can significantly affect print quality, reliability, and even the range of features available on your machine.
Choosing the right firmware for your 3D printer can be a game-changer, especially when upgrading or customizing your printer. In this article, we’ll explore popular firmware options like Marlin and Klipper, compare them, and discuss which printer brands use specific firmware.
The Basics of 3D Printer Firmware
At its core, 3D printer firmware is the software responsible for interpreting G-code commands generated by slicing software and converting them into motor movements, temperature adjustments, and extrusion commands. Firmware resides on the printer's control board and dictates how the printer hardware operates. It controls everything from how fast the motors move to how the extruder heats and handles the filament.
Common 3D printer firmware features include:
- Temperature control
- Stepper motor control
- Extruder management
- Bed leveling systems
- Filament sensor handling
- Display interface for users
Without firmware, a 3D printer would not know how to perform these essential functions. Now, let’s dive into two of the most popular firmware types: Marlin and Klipper.
The Two Most Popular 3D Printer Firmware Options
Marlin Firmware: One of the most widely used firmware options for 3D printers, Marlin is an open-source firmware developed to run on inexpensive 8-bit and 32-bit controllers. It’s known for its reliability and versatility, which is why many manufacturers like Creality, Elegoo, and Bondtech rely on Marlin. Marlin supports a wide range of features such as auto bed leveling, filament sensors, and power loss recovery.
One of Marlin’s key advantages is its strong community support, which means there are plenty of resources available for troubleshooting and customization. The Marlin firmware is ideal for hobbyists and professionals alike who want reliable performance with lots of configuration options.
Klipper Firmware: While Marlin has been the go-to firmware for many years, Klipper has gained popularity for offering faster print speeds and improved precision by offloading much of the computation from the 3D printer's control board to a separate Raspberry Pi or similar device. Klipper is often praised for its ability to deliver smoother movements and improved accuracy without putting too much strain on the control board. Additionally, it allows for more advanced features like input shaping, which can reduce vibration and improve print quality.
Voron printers and some newer models from Bondtech and Elegoo have adopted Klipper firmware due to its focus on performance and efficiency. However, Klipper can be a bit more complex to set up than Marlin, making it more suitable for experienced users.
Marlin vs. Klipper: A Comparison
For users trying to decide between Marlin and Klipper, the question often comes down to what features you prioritize in your 3D printing experience.
- Ease of Use: Marlin is easier to set up out of the box and has wide compatibility with a large number of 3D printers. If you’re new to 3D printing or prefer a plug-and-play experience, Marlin is likely your best option.
- **Performance**: Klipper, on the other hand, shines when it comes to performance. With its ability to handle faster print speeds and advanced features like input shaping, Klipper offers significant advantages for users looking to push the limits of their 3D printer’s capabilities.
- Hardware Requirements: Marlin can run on standard 8-bit or 32-bit controllers, while Klipper requires a separate computer (usually a Raspberry Pi if the printer does not have native computing hardware) to handle much of the processing. This additional hardware requirement can be a barrier for some users but is worth it for those seeking higher precision.
Ultimately, if you are content with standard printing speeds and reliability, Marlin is a great choice. For those who want to maximize performance and don’t mind a more complicated setup, Klipper is the way to go.

Which Firmware is Used by Major 3D Printer Brands?
Many 3D printer manufacturers choose specific firmware to run on their machines, often customizing it to suit their hardware. Here is a quick rundown of some popular 3D printer brands and the firmware they use:
- Creality: Most Creality printers, such as the Ender and CR series, ship with Marlin firmware pre-installed. However, newer models have also begun to adopt Klipper due to its enhanced performance.
- Bondtech: Bondtech uses both Marlin and Klipper, giving users the flexibility to choose the firmware that best suits their needs.
- Voron: Known for its high-performance DIY kits, Voron exclusively uses Klipper firmware, which allows for fast, precise printing.
- Elegoo: Elegoo printers, including their popular Mars series, offer both Marlin and Klipper as firmware options, depending on the model.
- Snapmaker: Snapmaker uses a highly customized version of Marlin to handle its multifunctional capabilities, which include 3D printing, laser engraving, and CNC carving.
- Ultimaker: Ultimaker printers have historically used a combination of Marlin, Bondtech, and their own proprietary firmware.
- Bambulab: Bambulab operates on a proprietary firmware system, optimized specifically for their 3D printer hardware.
- Flashforge: Flashforge printers run a variety of firmware, including the Druid Firmware on their CoreBoard and Sailfish/Makerbot firmware for older models like the Flashforge Creator.
Knowing what firmware your printer uses helps determine what features you can unlock, how easy it is to customize your machine, and the level of support available.
How to Update or Change Your 3D Printer Firmware
Updating or changing your printer’s firmware can provide access to new features, improve performance, and help solve compatibility issues. Before diving into a firmware update, it’s important to research and ensure that the firmware you’re considering is compatible with your printer's hardware.
Here’s a basic overview of the steps involved in updating your firmware:
1. Download the firmware: Find the latest version of the firmware you want to install, whether it’s Marlin, Klipper, or another option.
2. Prepare your printer: Make sure your 3D printer is connected to a computer or other device capable of flashing firmware. Some printers may require a USB connection, while others can update via SD card.
3. Install the firmware: Follow the installation instructions provided with the firmware package. Marlin and Klipper typically provide detailed setup instructions.
4. Test the update: Once installed, run a few test prints to ensure everything is working correctly and that your printer is performing as expected.
Conclusion
Whether you’re a 3D printing hobbyist or a professional prototyping expert, understanding your printer’s firmware is essential to getting the most out of your machine. From Marlin’s reliability and versatility to Klipper’s advanced performance features, there’s a firmware option that suits every user’s needs.
