FAA – Immediate need for AM certification path. Applicants are beginning
to seek approval for AM parts (the GE fuel nozzle was addressed as a point
solution). FAA typically relies on AMS standards to assess flightworthiness
criteria. Those standards are in work, yet currently unavailable. Advocating
development of a National Roadmap for Additive Manufacturing with
emphasis on durability and damage tolerance qualification methodologies.

AFRL/Wright-Patterson – Concerns primarily centered on reliability and
repeatability of AM parts in high-volume production settings. Extensive
work with ORNL to characterize the variability of Ti-6Al-4V built with
electron-beam powder bed process. Executing 3-year Title III agreement
with Aerojet Rocketdyne to demonstrate selective laser melting of engine
components.

NAVAIR – Advocate of applying Integrated Computational Materials
Engineering (ICME) to quantify the interdependence of processing-
structure-property-performance for AM materials. Recently qualified (as a
point solution) a flight-critical AM Ti-6Al-4V link and fitting for test flights
on the V-22 Osprey
