Based on the manufacturing technique and its energy source, AM processes are divided into several distinct types. Frazier [1] categorized these manufacturing systems into three major groups of powder feed, wire feed, and powder bed systems. Powder and wire feed systems, also known as directed energy deposition techniques, are suitable for both production and maintenance. With these systems, it is possible to deposit new layers of materials on worn old parts to repair them. Powder bed systems can generally be used for manufacturing purposes; however, they can also be considered for repair and maintenance but with more limitations [13].
