Welcome! Our group focuses on the development of novel additive manufacturing technologies to create unique functional, interwoven architectures and devices that cannot be created with conventional fabrication methods. We seek to advance the scientific understanding that enables the assembling and processing of functional nanomaterials as well as the seamless integration of diverse classes of materials. We develop a multi-scale, multi-material 3D printing approach that is fundamentally free from the constraint of the conventional two-dimensional, top-down fabrication methodologies. The abilities to create freeform multi-scale functional architectures and devices could overcome the geometrical, mechanical and material dichotomies between conventional manufacturing technologies and a broad range of three-dimensional systems. Ultimately, we strive to address unmet clinical needs by creating tailorable three-dimensional free-form biomedical devices with our advanced manufacturing technologies.
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.
