Similar to computer technology in the '60s, 3-D printing is a universal technology that has the potential to revolutionize our life by enabling individuals to design and manufacture things.
From Hod Lipson
Worrying about how you're going to make something is a huge constraint - most people can't make anything at home because it's too expensive.
We tend to think of science as finding equations, like E=MC2, that are simple and elegant. But maybe some theories are complicated, and we can only find the simple ones.
Basically, any material you can squeeze, melt or generate into a powder, you can print.
When it costs you the same amount of manufacturing effort to make advanced robotic parts as it does to manufacture a paperweight, that really changes things in a profound way.
