High entropy alloys (HEAs) with multi-component solid solution microstructures have the potential for large-scale industrial applications due to their excellent mechanical and functional properties. However, the mechanical properties of HEAs limit the selection of processing technologies. Additive manufacturing technology possesses strong processing adaptability, making itthe best candidate method to overcome this issue. This comprehensive review examines the current state of selective laser melting (SLM) of HEAs. Introducing SLM to HEAs processing is motivated by its high quality for dimensional accuracy, geometric complexity, surface roughness, and microstructure. This review focuses on analyzing the current developments and challenges in SLM of HEAs, including defects, microstructures, and properties, as well as strengthing prediction models of fabricated HEAs. This review also offers directions for future studies to address existing challenges and promote technological advancement.

具有多组分固溶体微观结构的高熵合金（HEA）由于其出色的机械和功能特性而具有大规模工业应用的潜力。但是，HEA的机械性能限制了加工技术的选择。增材制造技术具有很强的加工适应性，使其成为克服此问题的最佳候选方法。这份全面的综述检查了HEA选择性激光熔化（SLM）的当前状态。将SLM引入HEA处理是由于其高质量的尺寸精度，几何复杂性，表面粗糙度和微观结构。这篇评论的重点是分析HEA SLM的当前发展和挑战，包括缺陷，微观结构和性能，以及制造的HEA的强化预测模型。这篇综述还为将来的研究提供了方向，以应对现有挑战并促进技术进步。
