Review on Quality Control Methods in Metal Additive Manufacturing

Metal additive manufacturing (AM) has several similarities to conventional metal manufacturing, such as welding and cladding. During the process, both AM experience repeated partial melting cooling, referred deposition. Owing deposition, welded products often share common product quality issues, layer misalignment, dimensional errors, residual stress generation. This paper comprehensively reviews in monitoring methods between manufacturing. It was observed that a number of applied are interrelated; therefore, they can be used complementarily with each other.
