Additive manufacturing (AM) offers unprecedented design freedom and manufacturing flexibility for processing complex components. Despite the numerous advantages of AM over conventional manufacturing methods, there are still some issues and bottlenecks that hinder the wide-scale industrial adaptation of AM techniques. The emerging field-assisted additive manufacturing (FAAM) is a designation that combines different auxiliary energy fields (e.g., ultrasound, magnetism, etc.) to overcome limitations in AM by benefiting from the intrinsic advantages of auxiliary fields. This work provides an up-to-date and dedicated review of FAAM in metallic materials, assisted by mainstream auxiliary magnetic, acoustic, mechanical, and thermal fields, as well as some emerging fields. The work principle and interaction mechanism between the field and the deposited metallic materials are elucidated. FAAM processes simulation and modelling are also reviewed. The auxiliary fields can affect the melt pool convection and dynamics, alter the temperature profile and thermal history during material solidification and induce stress or plastic deformation to the deposited materials. Hence, the effects of the auxiliary fields on the melt pool dynamics, solidification kinetics, densification behaviour, microstructure and texture, mechanical properties and fatigue performance are reviewed and discussed in detail. The perspectives on the research gap and further development trends of FAAM are also discussed.

增材制造 (AM) 为加工复杂部件提供了前所未有的设计自由度和制造灵活性。尽管 AM 与传统制造方法相比具有众多优势，但仍然存在一些问题和瓶颈阻碍了 AM 技术的大规模工业应用。新兴的场辅助增材制造 (FAAM) 是一种结合不同辅助能量场（例如超声波、磁力等）以利用辅助场的固有优势来克服 AM 局限性的名称。这项工作在主流辅助磁场、声学、机械和热场以及一些新兴领域的协助下，对金属材料中的 FAAM 进行了最新和专门的审查。阐明了场与沉积金属材料之间的工作原理和相互作用机制。还审查了 FAAM 流程模拟和建模。辅助场会影响熔池对流和动力学，改变材料凝固过程中的温度分布和热历史，并对沉积材料产生应力或塑性变形。因此，辅助场对熔池动力学、凝固动力学、致密化行为、微观结构和织构、机械性能和疲劳性能的影响进行了详细的回顾和讨论。还讨论了 FAAM 的研究差距和进一步发展趋势的观点。辅助场会影响熔池对流和动力学，改变材料凝固过程中的温度分布和热历史，并对沉积材料产生应力或塑性变形。因此，辅助场对熔池动力学、凝固动力学、致密化行为、微观结构和织构、机械性能和疲劳性能的影响进行了详细的回顾和讨论。还讨论了 FAAM 的研究差距和进一步发展趋势的观点。辅助场会影响熔池对流和动力学，改变材料凝固过程中的温度分布和热历史，并对沉积材料产生应力或塑性变形。因此，辅助场对熔池动力学、凝固动力学、致密化行为、微观结构和织构、机械性能和疲劳性能的影响进行了详细的回顾和讨论。还讨论了 FAAM 的研究差距和进一步发展趋势的观点。详细回顾和讨论了微观结构和织构、机械性能和疲劳性能。还讨论了 FAAM 的研究差距和进一步发展趋势的观点。详细回顾和讨论了微观结构和织构、机械性能和疲劳性能。还讨论了 FAAM 的研究差距和进一步发展趋势的观点。
