The process is called Stereo Lithography. At least one of the processes...
It is a laser-hardened low grade plastic that acts as a 3-D plotter for CAD
files. It is used for prototyping plastic parts.
Problem is cost of the equipment $175,000-and up (way up!). Also, the
tolerances of the prototyped part are typically less than desirable for
small Lego-type parts.
Hope this helps
