That's been out for a few years now. Basically it can make anything out of plastic. If you want metal you still end up using a 5 axis waterjet though. 3D printing is mainly for testing work to make sure parts will fit together right. Just a fancy version of the computer based 3D modeling that we've been using for years.
We used a '3d printer' aka rapid prototype machine to produce wings, fuselage parts, and other pieces for wind tunnel modles in college right from our 3d computer models. Works great, but is brittle. They probably have better ones now.
I would wear it out printing copies of everything I could find. In the end, I would have a life-size plastic replica of my car.
Most of the ones I've seen only work on parts up to 8" long. I've heard of bigger ones but never seen it yet. The plasic that it uses basically is full of air pockets and isn't very thick, so if you expect to actually handle the part more than a dozen times or have big hands expect to make a few pieces so you have a spare. The most common use you'll see in the automotive field is to print out a part and than use that as the basis for testing aerodynamics or flow rates or what ever before tooling is made for the actual parts.
