4D Printing and Smart Structures
4D printing is a combination manufacturing technology of 3D printing and smart materials. It means 3D printed structures can perform a shape change into a new structure by certain stimuli. As figures show that simple and flat structures can become into complex helical, twisting and DNA structures. We realized our designs by controlling printing path and the properties of smart materials. We are able to produce smart structures with unique function, excellent mechanical strength, and special physical properties. For example, we designed an adaptive Poisson’s structure with our 4D printing technology. Therefore, 4D printing opens opportunities for many fields, such as robotics, aerospace, and drug delivery, etc.
