I am working with a global supplier right now on using Electron Beam Melting technology. We are very far from growing a functional turbine, but I am making a real engine parts that will fly in a year or so. Small steps. Most of the stuff you see actually has as much machining as a traditionally machined part, but this is changine very rapidly. Titanium, CRES, Inco.....lost of good materials available.

Very cool stuff!
