Hi Folks,
Rapid prototyping has been around a while. I first was exposed to it in about '89.
Certainly not an end all, but it's widly accepted industrially. The most bisarre thing
we "printed" was a human skull with a tumor, took the information from an MRI, next
day the model was in the hands of a surgeon for review so he could form his procedure.
All kinds of neat stuff
Cheers.
