Yes--amazing!
DH's research has used a 3D printer (to print out a computer program's self-generated design for a "robot"), but the printed objects were pretty small. That was maybe 8 or 9 years ago, when 3D printers were in their infancy. I can't believe how much they've evolved!
I just read a column yesterday about the potential applications to fashion (and other kinds of personal consumer) manufacture. I hope it doesn't come about in my lifetime--I don't think I could adapt!
