Rick, et alii...
Such systems are much older than that. When I was a securities
analyst for a Wall Street firm back in the late 1980s, one of the
companies we followed was 3D Systems (NASDAQ: TDSC,
http://www.3dsystems.com/company/index.asp). They are the originators
of rapid prototyping technology, and were making and selling such
systems in 1986. Their popular system when I was following them used
a sort of powdered wax which was selectively sintered by lasers to
form the part, with the unsintered powdered wax simply falling away.
A friend's family owned a machine shop in the early 1990s that
employed a rapid prototyping machine which employed paper as the
medium. It digitally cut the scanned, mapped, or digitally drawn part
into a zillion wafer-thin slices (think CAT scan), cut each slice out
of paper, and stack laminated all of the slices into the finished
form. All that was required was a bit of fairing, and one had the
completed model in hand.
Of course, the technology probably goes back even farther, all the way
to Da Vinci. I think it's in his notebooks, right between the Diving
Bell and his quotation about "making stuff".
All the best.
