Multi-scale 3D Printing of Active Electronics and Devices
Developing the ability to 3D print various classes of materials possessing distinct properties could enable the freeform generation of active electronics in unique functional, interwoven architectures. Achieving seamless integration of diverse materials with 3D printing is a significant challenge which requires overcoming discrepancies in material properties in addition to ensuring that all the materials are compatible with the 3D printing process. Indeed, to date, 3D printing has been limited to specific plastics, passive conductors, and a few biological materials. Here we are developing a multi-scale extrusion-based 3D printing approach that enables the integration of a diverse classes of materials to create a variety of 3D printed electronics and functional devices with active properties that are not easily achieved using standard microfabrication techniques.
