Selective laser melting (SLM) additive manufacturing technology holds the broad prospect for the preparation of high-performance complex metal components owing to its high processing accuracy, short manufacturing cycle, and high material usage. Magnesium (Mg) alloys are the lightest metal structural material and provide the benefits of low density, substantial specific strength and specific stiffness, good damping and shock absorption performance, and good biodegradability. Thus, it is worthwhile to employ SLM to manufacture Mg alloys, which is predicted to widen the application scope of Mg alloys. In this study, a comprehensive review on SLM of Mg alloys focusing on the preparation of Mg alloy powders, SLM process parameters, metallurgical defects, microstructure and mechanical properties of the as-built state, post-processing, and special equipment developed for SLM of Mg alloys is given. Finally, the future development trends of the SLM of Mg alloys are explored.
