  • Temperature-controlled multi-material overprinting
    Patent number: 11826951
    Abstract: A three-dimensional (3D) bioprinting method and system are disclosed. The method includes disposing/immersing a printing platform or surface into a first bioink, such as a bioink resin, curing one or more layer of the first bioink resin onto the printing platform or surface, and removing the printing platform or surface from the first bioink resin. The process is repeated with a second bioink resin such that the second bioink resin is cured on top of the one or more layer of first bioink resin, and can be further repeated with a third or even fourth bioink resin. By varying constituents of one or more or each bioink resin (such as living cell type or polymer), complex, multilayered tissues can be engineered. A system capable of performing the method is also disclosed.
