High speed 3d printing system for wound and tissue replacement

A method for creating a three-dimensional tissue construct of a desired shape for repair or replacement of tissue of a tissue cavity of an organism, the method comprising:

• injecting at least one biomaterial and at least one cell in a three-dimensional pattern into a first material such that the at least one biomaterial and the at least one cell are held in the desired shape of the tissue construct by the first material.
