3D Printers are becoming more realistic

The above video (in YouTube) shows the successful replication of a wrench from the original object being scanned to the usage of the "printed" wrench as an actual tool.

I remember that I read about these 3D printers not that long ago, but seeing the process and the results in action is something else.

The following video about the ZPrinter® 650 gives a more technical description of the features and the capabilities of this device. It was uploaded last year (June 4, 2010), so there might be even more sophisticated models out there. Still, it is quite impressive. Something to see (it lasts 4'17"):
