I’m sure everyone knows what 3D printing is but for the uninitiated; you create a 3D CAD model of whatever it is you want to make, you then make a tool path of the model for the molten plastic to follow, then you send the tool path program to a specialised printer add some molten plastic and hey presto! If it was that simple of course we’d all be doing it but that isn’t the point of this post.
