10. A multi-nozzle biopolymer deposition apparatus comprising:
-
(a) a data processing system which processes a designed scaffold model and converts it into a layered process tool path;
(b) a motion control system driven by the layered process tool path; and
(c) a material delivery system comprising multiple nozzles of different types and sizes which deposits specified hydrogels with different viscosities thereby constructing a scaffold from the designed scaffold model.
