Abstract

Oak Ridge National Laboratory (ORNL) and Lockheed Martin demonstrated the capability of additive manufacturing (AM) technologies to reduce the cost and material scrap associated with the production of aerospace components. The AM technology demonstrated the ability to fabricate fully functional complex components at reduced production costs and significant material and energy savings. AM also had the potential to decrease component lead times and fabricate complex designs considered impossible through conventional processing technologies. A Bleed Air Leak Detect (BALD) bracket used in the hot side of the engine on Lockheed Martin's Joint Strike Fighter platform was selected for this study. The BALD was classified as a tertiary structure under light loading, which simplified the certification process and increased the potential to implement AM technology into production.
