Abstract: National major missions such as flight-frequency transportation and manned lunar landing have raised new requirements for the development of advanced equipment, demanding even orders-of-magnitude leaps in the performance metrics of key components. However, traditional design and manufacturing methods are limited by the separation of material, structure, manufacturing, and function elements, making it difficult to meet these demands. There is an urgent need to develop new manufacturing technologies capable of achieving ultra-high-performance/function structures. Building on preliminary exploration and practice, the concept of meta-structure manufacturing and attempts to elucidate its essence and characteristics from the perspectives of dimension, scale, and order is proposed. It outlines the technical framework of meta-structure manufacturing, presents several research case studies, and finally analyzes and prospects its application scenarios from the viewpoints of material utilization, energy conversion, and information regulation. Through this paper, we aim to consolidate research efforts across the industry, break through traditional concepts and paradigms, and pioneer a new disciplinary field in meta-structure manufacturing technology.
