1. A method of fabricating a three dimensional living tissue, said method comprising:
providing an article fabrication system comprising:
a material deposition tool;
a material deposition device having a tool interface for receiving the material deposition tool, the tool interface of the material deposition device being movable relative to a substrate to dispense material from the material deposition tool to the substrate; and
a system controller operably connected to the material deposition device to control operation of the material deposition device and
dispensing material from the material deposition tool mounted on the tool interface of the material deposition device, in amounts and at positions on the substrate in response to instructions from the system controller, whereby a three dimensional living tissue is fabricated on the substrate, and wherein the material is a hydrogel comprising seeded cells.
