Abstract

Four-dimensional (4D) printing recently emerges as an important development by adding a time dimension to 3D printing technology. The fabricated structures by 4D printing have been developed so that can transform their geometry precisely from a flat shape to a deployed configuration in response to an environmental stimulus. There are various stimuli that enable direct 2D-to-3D transformation by bending, folding, twisting of the printed structures. This chapter deals with the 4D printing concept for the design and fabrication of origami structures using active materials. The latest advances in stimulus-responsive materials, design concept, and printing techniques as well as the operational parameters which have a high impact on the functionality of the origami structures will be the major focus of this study. Lastly, the potential and functionality of the 4D printed origami structures for various applications will be discussed, followed by technical consideration for the fabrication process.
