I wanted a cast of my face: a 3D positive, as closely resembling my real face as possible. I considered using 123D Catch to model my face and then print it out on our fancy 3D printers. But that's needlessly expensive and inaccessible (except for 123D Catch, which you should look up if you haven't heard of it). This method is messy and fun, and can be done in your home.
So I got some materials online, a (mostly) willing volunteer
, and some helpers
, and we set about things.
I got a lot of help from this instructable
, but we modified the process enough that I think it deserves its own step-by-step.
Why did I want a cast of my face? It will all be explained in time. But rest assured, I have further plans for it.
