The Pentagon wants to put additive manufacturing to broader use, but barriers remain.

For years, Pentagon officials have have been bullish about using 3D printing to build and fix weapons quicker and cheaper.

But its widespread use by the military has been slowed by regulatory and legal hurdles, experts say.


In hypersonics, 3D printing could cut the time to make a parts “from 18 months down to a matter of weeks,” Orringer said. But certifying new manufacturing techniques could take years, decades or more. Orringer has created a non-profit called Applied Science & Technology Research Organization of America, or ASTRO, to help bring advanced technology into defense-related manufacturing.
