The additive manufacturing technique is gaining attention because of its rapid prototyping ability, the ability to manufacture intricate geometries, and flexibility in changing designs. However, it suffers from drawbacks such as dimensional accuracy, surface finish and unfused powder particles. The unfused powder inside the artifact is mainly due to process parameters such as laser speed and laser power. These sorts of defects are responsible for the failure of the part. The goal is to employ a non-destructive testing technique as an in-situ to signify the presence of the defect early in the product development cycle so that manufacturing parameters can be changed to avoid the defect in the successive part.
