In an embodiment, a system includes a three-dimensional (3D) printer, a feedstock, and a laser. The three-dimensional printer includes a platen including an inert metal, and an enclosure including an inert atmosphere. The feedstock is configured to be deposited onto the platen. The feedstock includes a halogenated solution and a nanoparticle having negative electron affinity. The laser is configured to induce the nanoparticle to emit solvated electrons into the halogenated solution to form, by reduction, a ceramic and a diatomic halogen.

An ink mixture is manufactured by mixing carbon, graphite, and solvents in a mixing system which may include a Cowles disperser. The conductive portions (e.g. carbon, graphite) are evenly and universally dispersed, because an even dispersal means the conductivity of the resulting conductive strip (electrode) will be even, consistent, and reliable. The various embodiments of the ink mixture comprise a blend of different conductive pigments, including but not limited to carbon black and graphite. These embodiments must be grinded until below 6.5 Microns in particle size.

An ink contains an organic solvent and a coloring material, wherein the ink has a droplet breakage time of 17.0 msec or less according to elongation viscosity measuring.
