Four-dimensional (4D) printing technology is an extension of three-dimensional (3D) printing technology that enables a 3D-printed static structure to dynamically change its shape with time.Therefore,the re-sulting structure can undergo self-folding/unfolding assisted by some stimuli.This technology has made much initial progress in many industrial fields.Aiming to investigate the in-depth application value of 4D printing,this study reviews the recent research and application breakthroughs of 4D printing in sev-eral emerging directions,including the simulation of plant and animal behaviors,smart tissue scaffolds and biomedical devices,food printing,digitalization of industrial art design,renewable energy,intelligent communication,soft electronics and robots,vehicle optimization,textile customization,and flexible ma-chinery and mechanical structure.Based on the analyses of specific cases and processes,we present the current obstacles to large-scale applications and the future prospects.
