It's a pretty specialist bit of kit and...will never be a standard office gadget
Although Thomas J Watson was misquoted (http://en.wikipedia.org/wiki/Thomas_J._Watson#Famous_misquote), the thrust of the comment wrongly attributed to him was common thinking in the early computer age. The fact is, people find uses for gadgets as the price comes down, which brings the price down further, which allows other people to find uses for them, ad not quite infinitum. You might be able to turn a small profit in the mean time, but I'd expect 3d printers to be 1/10th of the current price within a decade and in place at every office where 3d objects are designed, from architects to jewellers.
