NextEngine 3D scanner
This just looks way too cool

I'm not sure how they do the single casting moving parts (like the steam engine near the end of the clip) as I would intuitively think assembly would be required. And how can the scanner see those gaps that are hidden?

They are talking about two separate technologies - scanning and printing. That the printer can print fully assembled products does not mean that the scanner can scan them, and I bet it can't. The 3D models for those prints were done in some kind of CAD software.
The printer slices the 3D model up into very thin layers and builds up the print layer by layer- each layer needs to be "somewhat" attached to the layer below it, but this support can be made so that it'll break when the part is moved.
So my guess is that they print in one "connected" piece, but with the supports that connect e.g. two cogs small enough that they simply snap off when you first turn it.
