4D printing technology is a variable characteristics rapid prototyping technology, which is mainly based on 3D printing. It additively manufactures the desired object with intelligent materials. The molding firmware can be stimulated by the external environment, in terms of its shape, structure or function of the time dimension changes. Since the technology was proposed, it has attracted the attention of a large number of scholars. With the continuous deepening of research on 4D printing technology, this technology plays a significant advantage in the interdisciplinary integration. This paper first reviews the research status of shape memory intelligent materials in 4D printing, and then elaborates the application research of 4D printing technology based on shape memory intelligent materials in the fields of medical, bionic, military and life product manufacturing. Finally it looks forward to the potential applications and challenges of 4D printing shape memory intelligent materials in the future development. [ABSTRACT FROM AUTHOR]
