The Necessity of Defect and Inner Structure Inspection in Additive Manufacturing
With conventional machining of metal component parts, the interior structures are often taken for granted as solid, leaving little room for doubt about the internal quality. With additive manufacturing (AM), however, the part isn’t affected by welding or machining but rather by the quality of powder used in the material and how it spreads or layers during the build process. These concerns, as well as other factors that might cause voids or material impurity to form in the structure, are critical elements for inspection in the quality assurance process for AM.
