As aerospace and defense assets continue to age and exceed the lives they were expected to be in service, the need for spares and repairs continues to increase. Advanced manufacturing concepts such as Additive Manufacturing (AM) are required in order to reduce spare part lead times and the need for costly, long lead tooling. This presentation will walk through the AM technologies that are prevalent within the aerospace and defense industry for spares and repairs applications. Two technologies that will be discussed include hybrid AM and cold spray. A discussion around the advancements seen to date in AM for sustainment as well as what hurdles are still yet to be overcome will ensue.
