Just a little thought about modeling in general...

just was watching this programme about the newest printers, and they were experimenting with a 3-d plastic printer.
I was wondering, could this mean the next step inmodel car making?
First developping a 3-d model, "printing" it, and making moulds of it ?
This could mean we could have every model of every car ever made! and It doesn't seem so far of. Imagine within a few years the priices of those machines will be as low as computers, one with skill and dedication would be able to make models of every car he-she wants!
chack this out ;
