Does a 3D printed plastic living hinge need to be thick? Can 3D printed plastic living hinges last for hundreds or even thousands of cycles?

It's a common belief that to make a 3D printed living hinge you need to make it thick and the plastic hinge will only last for a handful of cycles.

In this video we will challenge these common beliefs and show how to make a living hinge that can last for hundreds, and possibly even thousands of cycles.

Living hinge bend radius, material, thickness, and 3D printing parameters are the four main parameters in plastic living hinge design.

We will explore these in detail using a small case as an example design.

By the end of this video you will learn some basic design principles and guidelines so that you can design living hinges that will last for a long time.
