I remember seeing a web page describing a process that deposited (sprayed?)
material (plastic?) to build up a CAD design so that in the end you have a
3-D prototype of your design.

Basically, a CNC machine that adds material, not takes it away.

Can someone point me to a web reference of this type of machine?

Thanks,
Dave
