A new research project at the Hebrew University of Jerusalem is working to develop a new 3D printing manufacturing process that will enable designers to easily create hybrid machine elements and sensors that allow for the development of completely interactive systems. Working proofs of concept have been developed by the researchers as individual mechanical components that have fully integrated sensors capable of performing mechanical functions while sensing and reviewing its own performance. An example of the hybrid element in action is a 3D printed screw and a dedicated, 3D printed screwdriver that was designed to monitor the screw while it is being driven in with the screwdriver.
