金属增材制造（AM）工艺，例如选择性激光熔化（SLM），使粉末金属能够形成任意三维形状。铝合金由于其低密度和良好的机械性能而在许多高价值应用中是理想的，由于激光熔化铝粉的困难，SLM被认为是具有挑战性的。然而，最近的一些研究已经证明了成功的铝加工，并继续探索其在先进AM组件中的应用潜力。除了能够制造高度复杂的结构外，SLM还可以生产具有精细微观结构的零件，这些微观结构具有独特的机械性能。该领域的研究进展迅速，取得了令人鼓舞的成果，为科学和工业领域开辟了一系列可能的应用。本文报告了这一研究领域的最新进展，并强调了需要进一步关注的关键主题。
Metal additive manufacturing (AM) processes, such as selective laser melting (SLM), enable powdered metals to be formed into arbitrary three-dimensional shapes. For aluminum alloys, which are desirable in many high-value applications for their low density and good mechanical performance, SLM is regarded as challenging due to the difficulties in laser melting aluminum powders. However, a number of recent studies have demonstrated successful aluminum processing, and have gone on to explore its potential for use in advanced AM componentry. In addition to enabling the fabrication of highly complex structures, SLM produces parts with characteristically fine microstructures that yield distinct mechanical properties. Research is rapidly progressing in this field, with promising results opening up a range of possible applications across scientific and industrial sectors. This article reports on recent developments in this area of research and highlights key topics that require further attention.
