Metamaterial Design and Additive Manufacturing

Metamaterials are engineering materials that exhibit special mechanical, acoustic, thermal or electromagnetic properties through macro and micro cross-scale structural design. Additive manufacturing (AM) is an effective means to realize the forming of complex, integrated and personalized high-performance metamaterials, which changes the design from process-oriented to performance-oriented design, greatly improves the design space, and has a large application space in aerospace and other fields. To meet the multi-performance requirements of high-end equipment for components, the structural design has developed from mechanical metamaterial design to multi-physical field coupling functional metamaterial design. The metamaterial design and additive manufacturing of multi-physical field coupled functional metamaterials is an important development direction.

The problems to be solved in this Research Topic include the manufacturing accuracy analysis of additive manufacturing metamaterials, the structural design method of metamaterials based on additive manufacturing constraints, the multi-performance coupling mechanism of metamaterials in multiphysical fields, the influence of metamaterials' topological shapes on multiphysical properties, the influence of additive manufacturing process strategies on metamaterials' properties, and the research on high-precision, multi-material, and cross-scale additive manufacturing processes for metamaterials' geometric properties.

Possible topics, within this scope, include but are not limited to:
- Micro- and nano-lattices
- Mechanical metamaterial design and additive manufacturing
- Acoustic metamaterial design and additive manufacturing
- Thermal metamaterial design and additive manufacturing
- Multimaterial additive manufacturing technology
