3D printed gears - Which one performs the best?

PCBWAY is your best 3D Printing & CNC service: I’ve used almost all types of 3d printing gears and wondered which one performs the best. So I made some speed, torque and sound test for spur, helical and herringbone gears. At the end of this video, when you are going to do a mechanical project where you need to use a gearbox or gear, you will learn which gear type you should use, which I think is an important topic.
