Abstract: Additive manufacturing (AM), i.e., building up 3D objects by adding materials layer upon layer, has produced high-value, sophisticated components that cannot be fabricated using traditional methods. There are various AM methods, which are classified based on the input material and the type of process: bonding or melting techniques are utilized for solid materials, and if the input material is powder, however, binding, sintering, and melting processes are employed. Variations in raw materials and process parameters often cause uncertainties such as dimensional inaccuracy, discontinuities, nonhomogeneous microstructure, and anisotropic behavior. These may adversely affect the structural integrity and functionality of the product. Thus, the qualification of AM components requires more effort to verify their structural integrity and performance. Because differences in volume, build lots, and platforms make destructive testing for the qualification purpose less successful with AM techniques, non-destructive evaluation (NDE) has grown in popularity. However, due to their complicated geometry and high microstructural variability, AM parts are challenging to check with traditional NDE techniques. This paper reviews the current state of the NDE approaches used for assessing and qualifying additively manufactured metallic components.
