Abstract: 4D printing，also called variable-property rapid prototyping，is a technology that combines material， mathematics，and additive manufacturing． The materials used in 4D printing are smart materials，and the printed structure，shape，attributes，or function can change over time under environmental stimuli． With its characteristics of self-assembly，self-adaptation and self-repairing，flexible，personalized and intelligent structures can be designed． This article firstly introduced 4D printing technology，including the characteristics of 4D printing，molding methods，materials used and deformation forms，and then explained the application progress of 4D printing． Finally，it discussed the key issues and the future development direction of 4D printing．

Key words: 4D printing, research, application, progress
