Most 3D printers generally follow the same basic principle: build a 3D object by stacking hundreds of thin layers. It sounds simple, but there are so many different methods of 3D printing that it can be hard to wrap your head around them all. In this video, I share a handful of objects printed using all kinds of different 3D printers.
