Multi-material processing in selective laser melting (SLM) using AlSi10Mg and UNS C18400 copper alloy was carried out. The interfacial characteristics were analyzed with FIB, SEM, XRD, EDS and EBSD techniques. Al2Cu intermetallic compound was formed at the Al/Cu bond interface after the SLM process....
