基于激光的粉末床熔化（LBPF）工艺或通常称为选择性激光熔化（SLM）自其诞生以来已经取得了重大进展。最初，传统材料如316L、Ti6 Al 4V和IN-718使用SLM工艺制造。然而，不可避免地要探索继铁基合金/钢之后的第二大最流行的结构材料，即铝基合金的SLM制造。铝基合金由于表面氧化层的存在、熔体冷却过程中的凝固开裂、表面反射率高、金属导热系数高、粉末流动性差、熔化温度低等因素而表现出一些固有的困难。研究人员克服了这些困难，成功地通过SLM制备了不同的铝基合金。然而，目前还没有评论处理不同的铝基合金的SLM，其制造问题，微观结构，以及它们与性能的详细关系。因此，本审查试图介绍SLM过程，然后详细讨论形成合金开发过程的核心的工艺参数。其次介绍了铝基合金的加工和微观组织评价（包括缺陷、内应力等）的研究现状，这是处理的基础上，个别铝为基础的系列。这些合金的机械性能进行了详细讨论，其次是其他重要的性能，如摩擦学性能，疲劳性能等，最后，在这篇评论的结尾给出了展望。
The laser-based powder bed fusion (LBPF) process or commonly known as selective laser melting (SLM) has made significant progress since its inception. Initially, conventional materials like 316L, Ti6Al4V, and IN-718 were fabricated using the SLM process. However, it was inevitable to explore the possible fabrication of the second most popular structural material after Fe-based alloys/steel, the Al-based alloys by SLM. Al-based alloys exhibit some inherent difficulties due to the following factors: the presence of surface oxide layer, solidification cracking during melt cooling, high reflectivity from the surface, high thermal conductivity of the metal, poor flowability of the powder, low melting temperature, etc. Researchers have overcome these difficulties to successfully fabricate the different Al-based alloys by SLM. However, there exists no review dealing with the fabrication of different Al-based alloys by SLM, their fabrication issues, microstructure, and their correlation with properties in detail. Hence, the present review attempts to introduce the SLM process followed by a detailed discussion about the processing parameters that form the core of the alloy development process. This is followed by the current research status on the processing of Al-based alloys and microstructure evaluation (including defects, internal stresses, etc.), which are dealt with on the basis of individual Al-based series. The mechanical properties of these alloys are discussed in detail followed by the other important properties like tribological properties, fatigue properties, etc. Lastly, an outlook is given at the end of this review.
