Dr. Bhargava has invented a new method for 3D printing complex synthetic tissues. This new approach is quicker and far more scalable than other traditional approaches. Further, this solution has greater cell viability and adherence to hydrogel structures than other similar approaches. This method can be used to generate complex structures with sacrificial materials that have heterogeneous cellular complexes. Additionally, due to the methods used, multiple cell type in multiple layers can easily be integrated to fit the needs of the user and generate structures and complexes to fit most user needs.
