Additive Manufacturing (AM) is one of the innovative technologies to fabricate components, parts, assemblies or tools in various fields of application due to its main characteristics such as direct digital manufacturing, ability to offer both internal and external complex geometries without additional cost, and the potential of varying materials at the voxel level. However, despite high anticipations, AM as a real revolution for serial production of metal components has yet to be seen, mostly due to lacks of fundamental understanding, design engineering tools, and the global robustness of the value chains. This paper aims to provide a vision about the future of metal AM based on the collective knowledge of all ten scientific and technical committees of the International Academy of Production Engineering (CIRP).

增材制造 (AM) 是在各个应用领域制造组件、零件、组件或工具的创新技术之一，其主要特点包括直接数字制造、无需额外成本即可提供内部和外部复杂几何形状的能力，以及不同材料在体素水平上的潜力。然而，尽管人们对增材制造抱有很高的期望，但增材制造作为金属部件批量生产的真正革命尚未出现，这主要是由于缺乏基本了解、设计工程工具和价值链的全球稳健性。本文旨在基于国际生产工程学院 (CIRP) 所有十个科学技术委员会的集体知识，提供金属增材制造未来的愿景。
