I stumbled upon this link
today. You create a 3D model, upload it for them, and pay them to print out a physical version of your model. There are various materials you can choose from (even metals), and judging by the photos on the site, this is capable of some pretty amazing detail, including moving parts.
Now, I haven't used the service, and have no idea how well this stuff holds up, but I imagine this would be an incredible tool for people wanting unique film props. If you went for a metal print, I'm sure it could end up being fairly expensive, but for simple, small stuff, it seems affordable. I think I'm going to try this out in the next couple of months. 3D printing has interested me but I didn't realize it was prevalent enough for things like this. Looks pretty exciting.
Again, the link is www.shapeways.com
Just browse around and look at some of the things they've printed out. Really cool stuff.

, for an example, or this cube
