研究界和工业界甚至公众都一致认为，能够加工金属材料的增材制造（AM）工艺是一套改变游戏规则的技术，具有传统制造技术无法比拟的独特功能和巨大的应用潜力。不幸的是，尽管增材制造所能提供的一切，金属零件的质量和可重复性仍然严重阻碍了它们作为可行的制造工艺的广泛应用。在航空航天和医疗保健等对零件质量有严格要求的工业领域尤其如此。克服这一挑战的一种方法最近受到越来越多的关注，那就是过程监控和实时过程控制，以提高零件质量和可重复性。过去十年中，许多研究工作已经解决了这个问题，并继续被确定为高度优先的研究目标。在这篇综述论文中，我们填补了文献中的一个重要空白，即缺乏一个单一来源来全面描述已取得的成就，并提供有关金属增材制造工艺过程监测和控制领域仍需要实现的目标的见解。
There is consensus among both the research and industrial communities, and even the general public, that additive manufacturing (AM) processes capable of processing metallic materials are a set of game changing technologies that offer unique capabilities with tremendous application potential that cannot be matched by traditional manufacturing technologies. Unfortunately, with all what AM has to offer, the quality and repeatability of metal parts still hamper significantly their widespread as viable manufacturing processes. This is particularly true in industrial sectors with stringent requirements on part quality such as the aerospace and healthcare sectors. One approach to overcome this challenge that has recently been receiving increasing attention is process monitoring and real-time process control to enhance part quality and repeatability. This has been addressed by numerous research efforts in the past decade and continues to be identified as a high priority research goal. In this review paper, we fill an important gap in the literature represented by the absence of one single source that comprehensively describes what has been achieved and provides insight on what still needs to be achieved in the field of process monitoring and control for metal-based AM processes.
