Seems to be something of a fad to find out what you can do with 3D printing. If only someone would actually do something with the technology. No Elon Musks at Boeing or Lockheed I'm afraid.

Dulles, Virginia, January 18, 2016 -- Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, announced today that it has successfully tested a 3D-printed hypersonic engine combustor at NASA Langley Research Center. The combustor, produced through an additive manufacturing process known as powder bed fusion (PBF), was subjected to a variety of high-temperature hypersonic flight conditions over the course of 20 days, including one of the longest duration propulsion wind tunnel tests ever recorded for a unit of this kind. Analysis confirms the unit met or exceeded all of the test requirements.
