Been round for a while - there was an article on it in the August 2008 Silicon Chip. There are a variety of different systems, some cheaper, some higher resolution.
The process was invented by students at MIT in the early 1990s, and I first came across it then.
Costs are coming down, and increases in computing power have made it more and more affordable, but to make objects of any size and with fine resolution still requires a lot of data processing, and obviously the larger the size capability the more the cost of the machine (anyone priced A3 printers lately relative to A4 ones?).
