摘　　要：介绍了4D打印技术的基本概念、特点和发展历程,以及4D打印技术在军事、民用方面的应用设想及案例,并在此基础上,结合卫星有效载荷技术发展的需求,对4D打印技术在卫星有效载荷中的应用进行了展望,如利用4D打印进行空间机构的展开控制、天线幅面的在轨形变控制、空间环境下的温度自反馈控制以及在轨自修复等,4D打印技术的应用将有效降低上述系统的复杂程度,并提高其自适应性和可靠性。Some basic concepts,features,development history,application assumptions and cases used in military or civil of 4D printing technology are introduced. On this basis,in consideration of the requirement of payload development,4D printing technology applying prospect in payload on satellites are presented,including spacecraft deployable mechanism control,deformation control of antenna reflectors on orbit,thermal self-feedback control in space environment and self-repairing on orbit,and so on. The application of 4D printing technology would reduce the system complexity effectively and improve the adaptability and reliability.
