Engineers have invented a '4-D printing' method for a smart gel that could lead to the development of 'living' structures in human organs and tissues, soft robots and targeted drug delivery.
The 4D printing approach here involves printing a 3D object with a hydrogel (water-containing gel) that changes shape over time when temperatures change,
The study, published online today in Scientific Reports, demonstrates fast, scalable, high-resolution 3D printing of hydrogels, which remain solid and retain their shape despite containing water.
The smart gel could provide structural rigidity in organs such as the lungs, and can contain small molecules like water or drugs to be transported in the body and released. It could also create a new area of soft robotics, and enable new applications in flexible sensors and actuators, biomedical devices and platforms or scaffolds for cells to grow
