3D-printing is in an innovative stage where research institutions and companies are making fast and interesting progress to use the technology within many different fields. However, Harvard is already running successful research and development projects with 4D-printing where the fourth dimension is time. This means that researchers are creating materials that changes shape in response to environmental stimuli. The inspiration comes from how natural structures like plants respond and changes form. The researchers are using 4D-printed hydrogel composite structures as the printing material. Potential applications for 4D printing technology include smart textiles, soft electronics, biomedical devices and tissue engineering, which gives very interesting prospects for the future.
