| Abstract Scope |
As the Nation’s largest University Affiliated Research Center, the Johns Hopkins University Applied Physics Laboratory (JHU/APL) maintains a long-term, trusted relationship with the DoD and contributes greatly to the nation’s defense needs. JHU/APL conducts scientific research and engineering in the national interest, with additive manufacturing (AM) work focused on inventing new alloys, understanding solidification and defect formation mechanisms, and creating unique structures to enable new capabilities. Custom-tailored alloys are designed using computational insights and produced for sponsor-defined applications. Topology optimization and lattice design are coupled with AM to enable enhanced thermostructural capabilities. In situ monitoring, statistical design sampling, high-throughput testing and nondestructive evaluation, and machine learning are leveraged to understand and predict properties. Mission-driven AM research will be presented, providing examples of rapid material development for high temperature or corrosive environments, topology optimized structures for structural enhancement or thermal mitigation for aerospace applications, and novel actuation devices for spacecraft deployables. |
