Over the weekend I came across this article on 3D printer manufacturer MakerBot Industries on the Guardian website. Their product, the Thing-O-Matic Cupcake CNC, is a relatively affordable 3D printer at $649 USD. This is compared to other commercially available 3D printers which have been known to sell at prices over $35,000 USD!
Now it's still very likely that you'll have to learn the various 3D modeling and CAD software to create 'stuff' from the thing, but it seems to bring this technology well within the grasp of many.
If you are interested you can read the article at The Guardian, or go straight to the source and check out Brooklyn, NY based MakerBot Industries' website today.
