A prototype drain strainer orifice assembly will be installed on USS Harry S. Truman for a one-year test and evaluation trial, say the US Navy.
While the US Navy has been using additive manufacturing technology for several years, the use of it for metal parts for naval systems is a newer concept.
“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.”
The test articles passed functional and environmental testing, which included material, welding, shock, vibration, hydrostatic and operational steam, and will continue to be evaluated while installed within a low temperature and low pressure saturated steam system. After the test and evaluation period, the prototype assembly will be removed for analysis and inspection.
Additive Manufacturing is a term used to describe the technologies that build 3D objects by adding layer-upon-layer of material.
