3D printing has revolutionized the way we think about gears and gearboxes. With the right knowledge, you can now 3D print gears and 3D print gear mechanisms that are functional and reliable. One of the best things about 3D printing gears is the ability to adjust the gear ratio to match the specific needs of your project.

When it comes to the strength of 3D printed gears, there have been many concerns in the past. However, the strength of 3D printed gears has significantly improved with the advancements in materials and printing technology. With the right combination of material and printing process, 3D printed gears can be just as strong as traditional gears.

If you're looking to get started with understanding gears and mechanical principles, 3D printing gears is a good place to start. You can learn how to design 3D printed gears using popular CAD software like Fusion 360, which has a gear generator tool available as a plugin called ‘GF Gear Generator’. Alternatively, you can use FreeCAD to design 3D printable gears.

When it comes to materials, Polymaker Polymax PC is a popular choice for those looking to 3D print gears. Polymax PC, with its high strength and durability, is perfect for printing gears with 3D printer.

In this video I talk to you about how to design and 3D print gears that are optimised for strength and durability. This is based on my experience with 3D printed gears during my Raptor 2 project. I discuss the various types of gears available such as spur, helical and herringbone. I also discuss the importance of print orientation when 3D printing gears. This video is sponsored by Polymaker. I used PolyMax Polycarbonate to 3D print the gears shown in this video.

To summarise, with the correct tools and materials, you can easily 3D print a gearbox or 3D print a planetary gearbox that is functional and reliable. Whether you're just starting out or looking to improve your existing designs, the options for 3D printing gears are endless. In addition to the advice that I provide in this video, don't hesitate to experiment with different materials, like ‘Polymaker's Polymax PC Max’ and ‘PolyMaker PolyMide’.
