US Navy has approved the first 3D printed metal component to be used onboard an aircraft carrier, the Naval Sea Systems Command announced in a press release on Thursday.

"A prototype drain strainer orifice (DSO) assembly will be installed on USS Harry S. Truman (CVN-75) in fiscal year 2019 for a one-year test and evaluation trial," the statement said. "The DSO assembly is a steam system component that permits drainage/removal of water from a steam line while in use."

Huntington Ingalls Industries, which builds Navy aircraft carriers, proposed the prototype to be installed on a US Navy ship for test and evaluation.

“This install marks a significant advancement in the Navy’s ability to make parts on demand and combine NAVSEA’s strategic goal of on-time delivery of ships and submarines while maintaining a culture of affordability,” said Rear Adm. Lorin Selby, NAVSEA chief engineer and deputy commander for ship design, integration, and naval engineering. “By targeting CVN-75 [USS Harry S. Truman], this allows us to get test results faster, so—if successful—we can identify additional uses of additive manufacturing for the fleet.”
