There is a conference happening on additive manufacturing for the aerospace, defense, civilian, small sat, and UAV. This event is well sponsored and has many key stakeholders presenting such as: Lockheed Martin, Airbus, Boeing, NASA, Raytheon, and Pratt & Whitney.
This is game changing stuff, and an event I highly recommend that you attend. SpaceX launched and qualified 3D-printed Main Oxidizer Valve (MOV) body in one of the nine Merlin 1D engines.
