[TheForge] Re: What is it

There are other rapid prototyping processes.  Others I have seen are stereo
lithography in which a tank is filled with a special liquid a laser travels
around and solidifies portions of the plastic when it is done you have a
solid model.  There is also a process where a tiny nozzle extrudes a stream
of plastic that is laid up in layers ( imagine drawing with a tube of
toothpaste).   Another I have heard of but have not seen involves a machine
that cuts out pieces of paper and glues them up layer by layer, producing
something like a plywood.
