Hi Paul,
Ran across this at a recent trade show here in Oz. (www.amaero.com.au <http://www.amaero.com.au>) They are associated with Monash university in Melbourne (Australis) and have 3D printed a Jet Engine out of a variety of exotic metal powders. I asked a few question about cost and while it is still expensive it is amazing how quickly the cost of 3D printing is reducing. Apparently it is also very strong which is the thing that I could never get my head around when it comes to 3D printing. Worth a look.
