It is possible to produce multi-material structures and functionally graded materials with LPBF. The usability of powder mixtures provides a great potential for the production of metal matrix composites (MMCs) with advanced mechanical properties. Among the wide variety of MMCs, aluminum matrix composites are highly potential candidates for aerospace, automotive and biomedical applications due to their outstanding properties including high wear resistance, better chemical inertness and excellent mechanical properties at elevated temperature. Therefore, in this study, ceramic particle-reinforced Al-based MMCs produced by LPBF method are reviewed for the recent developments. Feedstock preparation methods for MMCs are emphasized. The effects of reinforcement particle properties and LPBF process parameters on the microstructure, densification behavior, hardness and tensile properties are discussed comprehensively. The strengthening mechanisms that occur with the addition of ceramic reinforcement are examined. Summary of the findings from this review and trends for future research in the development of Al-based MMCs by LPBF are addressed in the final section.
