Isn't it a little early to discount 3D printers? I remember in the late 70s, early 80s, dot matrix printers. Low-res, > 1 minute per page, monochrome, fanfold paper with feeds you have to tear off. Then it went laser, 300dpi, 600dpi, 1200dpi, 2400dpi, ink-jet, ink-jet color, prices went from $4k for laser printer to $80 for a scanner+fax+copy+color printer with auto-feed for scanning. Put photo paper in it and they'll print better than magazine quality color at 5760x1440dpi. Photo galleries now display ink-jet printed photos. We're in that 1980s level of 3D printer. Give it 10-20 years and who knows. Maybe they'll be able to spew out 15 steel nails per minute or print 28 different materials. In fact given they can currently print organs maybe they'll be able to print wood. I have no idea where it will go but it certainly seems silly to think that today's 3D printers is the end of 3D printer tech. That's like my high school teachers who used to tell me printers would never replace typewriters because typing looked good and 9pixel low-res dot matrix printers looked like ass.
