The process begins with searching and identification using Scopus with 212 records and Web of Science with 320 records. Next, multimaterial metal additive manufacturing is identified, including material extrusion, sheet lamination, liquid metal deposition, binder jetting, directed energy deposition, and powder bed fusion. Screening removes duplicate records and records not relevant to the topic. Then multimaterial laser powder bed fusion is separated into single material microstructure and properties, and single material functionality and applications. In parallel, welding, directed energy deposition, and other multimaterial metal additive manufacturing methods lead to dissimilar metal joining. Finally, the review includes technology overview, multimaterial laser powder bed fusion interface metallurgy, and multimaterial laser powder bed fusion functionality and application.Systematic literature selection and categorization process flow for the two-part review of multimaterial laser powder bed fusion (MM-LPBF)
Note(s): The methodology integrates primary LPBF research with foundational knowledge from dissimilar metal joining and directed energy deposition (DED) to establish metallurgical and functional frameworks
