I know nothing! Where is the place to start on 3-D printing? I called
some of my old friends in my old business and they said that they knew
nothing but had a whole bunch of projects that 3-D printing would
benefit. Things like simple representations of prototypes and such. I
need to make some parts for one of my wacky inventions. So, can I learn
enough and make a good purchase decision? I wouldn't mind having a
little desk-top business for a few clients that I know have a LOT of
money and do things by throwing it around.

I know nothing, either, so maybe start here?
