I believe the thread discussing "Rapid / Paper/Acrylic models" may be describing Stereolithography. Our company has an outside source that uses that process to produce detailed mockups using CAD files as the input to the machine. Basically a laser is suspended above a tank of liquid acrylic. As the laser hits the material it instantly cures. That first layer is the "bottom" of the part. A tray in the tank drops down about a millimeter then the laser cures the next layer. And so on and so forth. It takes quite awhile. The parts come out very nice and can be further detailed and painted. But when we had a piece made that was 6" H x"5 Lx"1W it cost +$200. It may be a bit expensive for a S sized car. They must produce those N and Z pieces in large batches to get the prices that low.
There are any number of web sites that explain the process. Try http://computer.howstuffworks.com/stereolith2.htm Bruce Yahoo!
