Hi everyone! Code the cat here! Today we will be using pictures to look at 3D printing and how it relates to computer science!

This is a 3D printer! It is currently printing an intricate ball out of plastic. But how did it get to here?

It first has to be designed using a computer program of course! You can use programs like Blender or go to websites like "Thingyverse" where people already have models created for you to use!
