A 4D printer for smart materials with magneto- and electro-mechanical properties

Researchers at Universidad Carlos III de Madrid (UC3M) have created software and hardware for a 4D printer with applications in the biomedical field. In addition to 3D printing, this machine allows for controlling extra functions: programming the material’s response so that shape-changing occurs under external magnetic field, or changes in its electric properties develops under mechanical deformation. This opens the door to the design of soft robots or smart sensors and substrates that transmit signals to different cellular systems, among other applications.
