Fax me an iPod, will ya?

Rapid Prototyping has intrigued me for some time. I think I first saw a fictional version of it in action in the movie "Small Soldiers." In the film, Chip Hazard and other characters are formed with a laser-looking thing that squirts their image into 3-D.


I saw similar technology employed in Mission Impossible, when Tom Cruise has a mask made so he can infiltrate the bad guys' camp. Basically, it's a technology that builds up layer after layer of goop into a shape designed by a computer aided drafting/drawing (CAD) system. It's called "additive fabrication," for it builds by building on itself, one tiny layer at a time. Primitive versions of this actually use old ink jet printer technology, so renaming Rapid Prototyping "3-D printing" seems to be a good idea to me.

I've seen footage of an iPod case being manufactured via rapid prototyping. It reminded me of a monster-making kit I had when I was a kid, a "fright factory!"



I've read that in short order parts can be ordered via computer over long distances and then just "printed" at your location. This will require one to have the hardware, of course, but imagine if this were to catch on!? It could reduce transportation costs, eliminate the middle men, and generally speaking be pretty darn cool! From what I understand, as this technology evolves and is coupled with nanotechnology, even computer components will be "manufactured" by pouring substances as per advanced CAD directives. One may actually, someday, be able to order something like an iPod to be built on site, on demand!
