Research

From human organs to engineering tools that are used in aerospace and automotive sectors, 3D printing promises to open up novel and significant manufacturing methods. These methods and other potential benefits have led to accelerated investment in the validation of current 3D printing technologies and the rapid exploration of new concepts, such as lightweight structural components and multifunctional tissue scaffolds. The rapid growth and disruptive potential of 3D printing demand further research that addresses the fundamental principles of 3D printing and likewise enables engineers to realize its capabilities. We can use these capabilities to develop material systems that obtain some of their properties via their structural organization rather than their intrinsic constituents. I am interested in applying the fundamentals of engineering mechanics to investigate novel material systems (e.g., nature-inspired and mathematical systems) with qualitatively different mechanical behaviors but using the same material composition. If structural patterns with different length scales are combined in a hierarchical manner, mixed-mode mechanical responses, such as bending–stretching, are possible. Multiscale metamaterials with properties heretofore unseen in engineered materials can be created by the 3D printing of flexible inks.
