3D Printing Progress
4D smart scaffolds for tissue engineering
May 25, 2018 United States
While 3D bioprinting is widely used to construct complex biocompatible structures, researchers are now attempting to extend the technique into the fourth dimension. Here, 3D printed objects can be made to "self-transform" over time, which means that they can take on different forms or functions when exposed to physical stimuli such as osmotic pressure, heat, current UV light or other energy sources.
