Additive manufacturing (AM), commonly known as 3D printing, is emerging as a promising method to produce certain EWIS components. This technology offers design freedom to create complex, lightweight structures and the ability to manufacture low-volume or custom parts without expensive tooling. In this article, we explore which EWIS parts can be built with AM, review FAA guidance on qualifying AM parts, discuss current process control standards for AM, and examine the challenges identified with 3D-printed aerospace components.
