Abstract In order to enhance the experimental interest and operational ability of undergraduate students, and further cultivate good scientific research literacy and innovation ability, we have designed an innovative experiments based on photocuring 4D printing technology for undergraduates. The experiment adopts digital light processing (DLP) based 4D printing technology which is based on photoinduced free radical polymerization. During the experiment, student can involve in every part of the experiment and experience entire printing process, which is aiming at enabling students to understand the principles of 4D printing, the material synthesis and 3D structure design. At the same time, through innovative design and programming of 4D printing structures, students can not only deeply understand and learn from the design and manufacturing process of deformable structures, but also deformation control mechanism of flexible structures. This approach fosters the experimental interest and improves the material design ability, experimental and practical ability of students, thereby enhancing their enthusiasm and participation in experiments.
