Abstract
A 3D printable feedstock ink is disclosed for use in a 3D printing process where the ink is flowed through a printing nozzle. The ink may be made up of a non-conductive flowable material and a plurality of chiplets contained in the non-conductive flowable material in random orientations. The chiplets may form a plurality of percolating chiplet networks within the non-conductive flowable material as ones of the chiplets contact one another. Each one of the chiplets has a predetermined circuit characteristic which is responsive to a predetermined electrical signal, and which becomes electrically conductive when the predetermined electrical signal is applied to the ink, to thus form at least one conductive signal path through the ink.
