"Printing soft and living matter in three dimensions"
The ability to pattern soft and living matter in three dimensions is of critical importance for several emerging applications. In this talk, I will first describe the fundamental principles that guide the design of printable materials and matrices for both direct and embedded 3D printing. I will then introduce new multimaterial printheads for patterning soft materials with spatially controlled composition and architecture. Such objects may find potential application as soft electronics, sensors, actuators, and robotic matter. Finally, I will highlight our recent efforts to create vascularized human tissues through the tight integration of stem cell biology, organoid differentiation, and bioprinting.
