Curtiss-Wright and Sintavia Deliver First Submarine Component Utilizing an Additively Manufactured Impeller to be Installed in a U.S. Navy Vessel

Curtiss-Wright’s EMS Division today announced that it has delivered the first submarine component with an additively manufactured (AM) impeller that will be installed in a U.S. Navy vessel.  

Curtiss-Wright’s Engineered Pump Division (EPD) in Bethlehem, PA, Bechtel Plant Machinery Inc. (BPMI) in Monroeville, PA, and Sintavia, LLC in Fort Lauderdale, FL, collaborated to develop, manufacture, test, and supply the first submarine component utilizing a qualified, metal additively manufactured part. Sintavia, a leader in designing and manufacturing critical additively manufactured defense components, provided the AM impeller after a thorough qualification process. This impeller was assembled into the pump and tested at Curtiss-Wright’s facility in Bethlehem, PA.  

Additive manufacturing technology offers a solution to the development of a product or component that historically has been difficult or costly to manufacture, often resulting in delays. The use of this technology is expected to provide a reliable and high-quality domestic source while also leading to shorter manufacturing lead times, increased quality, lower risk in performance, and improved delivery to further meet the needs of the U.S. Navy.  

“Sintavia has proven to be an invaluable industry partner, and we are excited about the opportunity to further solidify our partnership by increasing the number of additively manufactured parts for this application and other critical naval defense components,” said David Micha, Sr. Vice President and General Manager of the EMS Division. “In addition, we are proud to be providing the first critical service equipment utilizing an additively manufactured component to the U.S. Navy’s submarine program and look forward to expanding these capabilities in the future to more efficiently serve our customer.”  

“We would like to thank both Curtiss-Wright and BPMI for the opportunity to leverage Sintavia’s additive technology in the production of this critical component,” said Lindsay Lewis, Sintavia’s Corporate Vice President. “Leading-edge manufacturing processes such as AM will continue to be key differentiators in developing superior defense components in the years to come.”
