There are several different technologies used in "Rapid Prototyping". They each have advantages and disadvantages. The technology Eric refers to above was Selective Laser Sintering or SLS. The powder used for SLS only came in packages that cost about $4k. That was several years ago and while I continue to be active in the field, I no longer worry about budgets so I have no idea what costs are now.

"3D printing" is often used to refer to a different process called Fused Deposition Modeling, or FDM. The raw materials are much cheaper and there are FDM machines available that a typical team could afford if they make a lot of use of it. I'm talking <$2K. You have to put it together yourself, but that is just part of the fun.
