Defense companies are using Additive Manufacturing more often today to build parts for weapons: Aerojet Rocketdyne is using the technology to build rocket engines, Huntington Ingalls is using it to build warships and Boeing is 3D printing parts for its commercial, defense, and space products. “In particular, rapid prototyping, along with the creation of highly specific and technical parts are orders of magnitude faster and cheaper than traditional manufacturing methods,” said a recently released RAND report.
Someday, the military will 3D-print missiles as needed, the U.S. Air Force’s acquisition chief says. In the shorter term, he just wants to use Additive Manufacturing Technology to get broken planes back in the air. The roadblock is legal, not technical: “I have airplanes right now that are waiting on parts that are taking a year and a half to deliver. A year and a half,” Will Roper, the assistant Air Force secretary for acquisition, technology and logistics, said in an interview.
The Air Force is already 3D-printing niche projects whose original suppliers no longer exist. The problem is with parts whose manufacturers are still around, but which no longer make the specific item in need. Today’s 3D-printers could make short work of those deliveries, but some of those parts’ original manufacturers control the intellectual property —and so far, the service lacks clear policy for dealing with that: “The reason I can’t say we’re going to do it is we’re talking about government contracts and IP, so I have lawyers that are helping me and other contracts folks,” Roper said. “But it’s an area I’m going to stay focused because I see a way for win-win. And that doesn’t happen often in the government.”
