I went ahead and bought a 3D printer, the Makerbot Thing-O-Matic 3d Printer. For higher quality prints, this thing probably won’t do the trick. Then it’s better to use someone like Shapeways or Ponoko. They can even print in other materials, like metal and glass. But for quick prototypes, this is hopefully enough. If anyone nearby want to come see it in action, please feel free to come around. It takes 7 weeks for them to deliver it though. I guess they’re going to make it first… well the parts. I have to assemble it. If I had time right now, I’d build one from scratch, for example with my CNC machine.
