Re: OT: How Amazing
Yeah, they use those 3D printers to make models of new cars and things. It's really sci-fi looking.
Talking about "printing" 3D objects- I can't remember if it was here or somewhere else but I read about a new type of printer- that "prints" buildings! it's a robot that scoots around and leaves a trail of concrete behind it. It "draws" out the outline of the walls, waits for the concrete to set, then lays the next layer of concrete on top, and the next...
It can only do single-story buildings with domed roofs, but it sounds like a way-cool toy.
