1. A method for manufacturing nano-scale materials comprising:
flowing a first fluid carrying a first reagent through a first flow space of a first capillary, the first flow space being external to a cylindrical length of a second capillary that is concentric with and internal to the first capillary;
flowing a second fluid carrying a second reagent through a second flow space of the second capillary, the second capillary having an end that is the termination of the cylindrical length and that is within the first capillary; wherein the first fluid and the second fluid, upon passing the end of the second capillary, pass into a first mixing region, wherein the first fluid exhibits a laminar flow pattern through the first flow space and the first mixing region and the second fluid exhibits a laminar flow pattern through the second flow space and the first mixing region, the first and second reagents interacting within the first mixing region to form a nano-scale material;
flowing a third fluid carrying a third reagent through a third flow space of a third capillary, the third capillary being external to and concentric with a cylindrical length of the first capillary and the cylindrical length of the second capillary, wherein the nano-scale material within the first mixing region flows past a termination of the first capillary and thereupon passes into a second mixing region, wherein the third fluid exhibits a laminar flow pattern through the third flow space and the second mixing region and the flow exiting the first mixing region exhibits a laminar flow pattern through the second mixing region, the third reagent modifying the nano-scale material; and
depositing the modified nano-scale material from a print head to a print bed.
