Here is a special edition Hackit in honor of Roboexotica. Ever since making the decision to attend Roboexotica we’ve been speculating on the type of machines we’d like to see at such an event. Here are a handful of ideas:
Iceware via rapid prototyping: As we type this post, [Bre] is in the background attempting to build a RepRap style rapid prototyping machine that will construct shot glasses on demand. We were thinking it would be neat to cut beverage glasses out of blocks of ice using a milling machine, but why stick with normal milling equipment? It’s ice right; you could be doing something stupid like using a butane torch for your working tool. We then began to wonder “Has anyone built an ice based rapid prototyping machine?” You could just deposit water on a frozen surface to create your glassware. A group at the University of Missouri has been investigating “rapid freeze prototyping“. Since they’re using water, they only have to create the frozen shell of the part and then fill in the empty cavity with water to create a solid.
