My daughter asked me the other day. "what if there was a machine that we could just take some pictures and tell it what you wanted and it would spit it out? would that be great?"
My answer was "wait for it honey, eventually 3-d printing will get to a point where it'll be like the printer we have at home."
I then had to explain 3-d printing to two small kids. But 3-D printing strikes me as something that could be incredibly useful for everyone. Instead of ordering products online and waiting for them, some could be printed right off. I see the next generation embracing that sort of instantaneous purchase, nevermind the possibilities to create from a home office.
