Integration of diverse materials into 3D ordered structures is urgently required for advanced manufacture owing to increase in demand for high‐performance products. Most additive manufacturing techniques mainly focus on simply combining different equipment, while interfacial binding of distinctive materials remains a fundamental problem. Increasing studies on macroscopic supramolecular assembly (MSA) have revealed efficient interfacial interactions based on multivalency of supramolecular interactions facilitated by a “flexible spacing coating.” To demonstrate facile fabrication of 3D heterogeneous ordered structures, the combination of MSA and magnetic field‐assisted alignment has been developed as a new methodology for in situ integration of a wide range of materials, including elastomer, resin, plastics, metal, and quartz glass, with modulus ranging from tens of MPa to over 70 GPa. Assembly of single material, coassembly of two to four distinctive materials, and 3D alignment of “bridge‐like” and “cross‐stacked” heterogeneous structures are demonstrated. This methodology has provided a new solution to mild and efficient assembly of multiple materials at the macroscopic scale, which holds promise for advanced fabrication in fields of tissue engineering, electronic devices, and actuators.

通过宏观超分子组装制造多种材料的 3D 有序结构
由于对高性能产品的需求增加，先进制造迫切需要将多种材料集成到 3D 有序结构中。大多数增材制造技术主要集中于简单地组合不同的设备，而独特材料的界面结合仍然是一个基本问题。越来越多的宏观超分子组装（MSA）研究揭示了基于“柔性间距涂层”促进的多价超分子相互作用的有效界面相互作用。为了演示 3D 异质有序结构的轻松制造，MSA 和磁场辅助对准的组合已被开发为一种新方法，用于原位集成各种材料，包括弹性体、树脂、塑料、金属和石英玻璃，模量从几十MPa到70GPa以上。演示了单一材料的组装、两到四种不同材料的共同组装以及“桥状”和“交叉堆叠”异构结构的 3D 对齐。这种方法为在宏观尺度上温和高效地组装多种材料提供了一种新的解决方案，这为组织工程、电子设备和执行器领域的先进制造带来了希望。
