Military Parts Certification: The DoD’s process for certifying parts and approving components for in- flight use will have to evolve as additive manufacturing becomes more mainstream within the defense industry. This will require process optimization within the DoD, but is also dependent upon technological advancements in the accuracy and repeatability of 3-D printed components. Existing collaboration between military and civil agencies to address the challenges in 3-D parts qualification and certification processes3 suggests that future changes to existing certification regulations may be inspired by the collective experience of numerous agencies – both civil and military – as opposed to a single authority.
