Researchers have used model systems to mimic key aspects of in vivo human physiology and disease, and develop new fundamental understanding that would inform potential clinical therapies. In the past decade, three-dimensional (3D) cell culture models such as scaffold-based tissue engineering constructs, organ-on-a-chip, and organoid culture have been extensively used in the field. These 3D models provide good balance in experimental complexity between simple 2D cell cultures and systemic animal experiments. In this seminar, I will present recent work in our group related to the development of 3D in vitro models and new biofabrication       capabilities using extrusion- and light-based 3D printing technologies. First, I will present the development of a scalable model for bone tissue engineering using a   combination of cell-laden hydrogels and off-the-shelf sacrificial material and 3D printers. Second, I will present a femtosecond laser based processing method that    enables microscale interrogation of cell-ECM interactions occurring within 3D       hydrogel systems. Lastly, I will present the design and development of a new laser-based biofabrication platform that allows multiscale printing of ready-to-use  hydrogel biochips. I will also discuss the current challenges and new opportunities in this field.
