there are commercial machines that use a liquid photopolymer and a laser.
You can scan a 3d object or feed in a autocad drawing. The object is then
"built" from the bottom up 4 thousands of an inch at a time. You can create
up to a final object size of a cubic foot with one machine I have seen. Its
really cool to watch it make a part. The photopolymer is around $5 an ounce
though (I seem to recall).
