A method includes designing a part. The part includes at least one internal structure. The internal structure is designed to provide strain mitigation, energy dissipation, or impact resistance for the part during an emergency condition. The part is built by a layer-by-layer additive manufacturing process. While building the part, the internal structure is connected to the part.
