SLA light sensitive printers have been around since the 80s.

The Powder Printing Patents ( yes the alliteration is real ) that expire this year are the keys to useful parts printers. Hopefully they do become common place and as low cost as a good welder. 150 Watt Diode lasers and micro powders are common place and should be coming down in price. The key patent mechanisms that will allow powder printing are the only real barriers to driving down the price to where small shops and entrepreneurial individuals could afford them.
