Claim 13:
14. A method of additive manufacturing an article, comprising:
dispensing a first material from a first nozzle, the first material having a first viscosity;
dispensing a second material from a second nozzle, the second material having a second viscosity that is greater than the first viscosity;
providing the support structure nozzle; and
moving the first and second nozzles with respect to a printing surface so as to form an article including an outer volume defined by the first material and an inner volume defined by the second material, wherein the first nozzle dispenses the first material in a first droplet size, and wherein the second nozzle dispenses the second material in a second droplet size that is larger than the first droplet size, wherein the first aperture diameter of the first nozzle is at least 0.5 μm to not greater than 200 μm, wherein the second aperture diameter of the second nozzle is at least 5.0 μm to not greater than 5000 μm, wherein the support structure nozzle, the first nozzle, and the second nozzle each move independently of one another in the X- Y-, Z-spatial field, wherein the first nozzle and the second nozzle are configured to dispense the first material and the second material simultaneously at different positions in the X-, Y-, Z-spatial field.
