"We were challenged to provide something for the Navy and Marine Corps that they haven't thought of yet." -- Shanelle Foster
Shanelle Foster, an assistant professor of electrical and computer engineering, is a national finalist in the concept challenge hosted by the U.S. Chief of Naval Research. She will support the U.S. Navy and Marine Corps of the future with her research on 3D printing of magnetic cores used in electrical motors.
Her work was among nine projects highlighted at the Naval Future Force Science and Technology Expo in Washington, D.C., in July.
U.S. Chief of Naval Research Rear Admiral David J. Hahn introduced Foster as a finalist in the concept challenge. “The visionary ideas that we received from Challenge participants will enable us to get out in front of the rapid, ever-accelerating technology development and deployment cycle,” Hahn said.
“We were challenged to provide something for the Navy and Marine Corps that they haven’t thought of yet,” Foster noted.
She hopes to help the Navy eliminate the logistical difficulties of needing spare motors and generators in the middle of the ocean.
“In spite of the technological advancements in 3D printing, there is still a critical gap in understanding the functional and structural characteristics of deposited iron alloys for the design of magnetic cores in electrical machines, transformers, and other magnetic assemblies. While powder-based additive manufacturing processes have been used to produce fully-dense metallic parts, little has been done to develop functional 3D printed magnetic components,” she said.
Foster hopes to develop magnetic cores using additive manufacturing technology by investigating material magnetic properties. Her research will use binder-jet printing and vacuum sintering to process iron alloys, microscopy to measure the grain size and texture changes as a function of processing parameters and physical properties measures.
