US Naval Sea Systems Command (NAVSEA) recently approved the first metal part created by additive manufacturing (AM, also known as 3D printing) for shipboard installation, and Huntington Ingalls Industries’ Newport News Shipbuilding (NNS) sees long-term potential for ship construction, maintenance, and logistics if the 3D-printed part installation and operation proves successful. A prototype drain strainer orifice (DSO) assembly will be installed on US aircraft carrier USS Harry S Truman (CVN 75) in fiscal year 2019 for a one-year test-and-evaluation trial, NAVSEA confirmed on 11 October. The DSO assembly is a steam system component that permits drainage/removal of water from a steam line while in use.
