Rapid prototyping is nice, but today's rapid prototyping machines can't make "almost anything", not by a long shot. They can make a lot of pretty neat things, but not very much valuable. I have seen cup holders, iPod accessories, shot glasses and various kinds of support material. All in plastic, of course - these parts will not stand up to any significant forces. You can't make a combustion engine out of them, or anything requiring significant rigidity. (Want a skateboard? Keep dreaming).

I'm very excited about the future of rapid prototyping, but the headline is very misleading.

Other manufacturing machines also look promising (computer-controlled laser mills, CNC mills, etc), but I'm pretty skeptical that they will be available at reaasonable prices in the near future. I hope you'll prove me wrong, though.
