Study of dynamic material behavior using jetting and machining<\/p>\n\n\n\n

Different from using manufacturing as an approach to transforming raw materials into final products, we aim to use manufacturing to create complex dynamic loading conditions to study the dynamic material behavior of materials as well as investigate process-induced damage such as living cell injury or defect structures such as excessive grain growth. Specifically, we use inkjetting and laser-induced forward transfer to study the droplet formation behavior of complex fluids via the jetting and pinch-off process (with a shear strain rate up to 105<\/sup>\/s) and machining to study the dynamic material behavior of solids via the chip formation process (with a strain rate up to 108<\/sup>\/s).<\/p>\n\n\n\n

Three-dimensional (3D) printing of biological and engineering structures from difficult-to-print materials using inkjetting, extrusion, laser-induced forward transfer, and stereolithography<\/p>\n\n\n\n

Our additive manufacturing\/printing-related activities are to layer-by-layer scaffold-free fabricate human tissues and 3D engineering structures using jet-based (laser- and inkjet-based), filament-based (extrusion), and light-based (stereolithography) direct-write technologies. Instead of being a printing technology user, we strive to be a technology provider, which has been corroborated by our thirteen printing-related patents during the past several years.<\/p>\n<\/div>

Design and fabrication of microphysiological & engineered living systems and combinatorial materials<\/p>\n\n\n\n

Herein we strive to fabricate living cell-based 3D biological constructs using applicable printing and molecular engineering technologies. With cell\/organ printing as the most significant application venue, maskless printing is a revolutionary advance to print arbitrary cell patterns as well as to create heterogeneous 3D living constructs cell by cell. It is noted that the same approach can be readily applied to the printing of combinatorial materials as well. Most importantly, bioprinting or cell direct writing provides a promising solution to the challenge of organ donor shortage by fabricating vascularized, innervated thick tissue constructs to mimic the cellular organization of native organs, resulting in what is known as organ printing. Some envisioned products include microphysiological systems (MPS) and soft robots in addition to engineered living materials (ELM) and protocells\/prototissues.<\/p>\n<\/div><\/div>\n\n\n\n
