1. A method for forming a function-infused feed material for a three-dimensional printing technique, the method comprising:
solubilizing a functional additive into a medium, wherein the functional additive is selected from the group consisting of organometallic, electrochromic, and thermochromic additives; and
contacting a three-dimensional printing feed material with the medium to infuse the functional additive into the three-dimensional printing feed material to form the function-infused feed material.
