Abstract：Aluminum alloy and aluminum matrix composite materials perfectly fit the requirements of lightweight
parts in the industrial field for their high specific strength. With the development of modern industrial, more and
more aluminum alloy parts with complex structure are required in various field, but traditional processing methods
are difficult to prepare. Selective laser melting technology can realize the near-net forming of metal parts, it can also
be used to prepare the complex shape and structure of parts. It has a wide application prospect in aerospace, advanced
transportation and other industrial fields. In this paper, the research on aluminum alloy and aluminum matrix
composites at home and abroad in recent years is summarized, and focus on the microstructure, mechanical
properties and corresponding strengthening mechanism of several typical aluminum alloy systems and composite
processed by selective laser melting. Finally, the present problems and future development trends are summarized.
