Abstract
A method for forming a transparent ceramic, in accordance with one embodiment, includes forming a green body by material jetting an ink, and processing the green body to form the ceramic to transparency. A product, in accordance with one embodiment, includes an ink for forming a transparent ceramic. The ink is physically characterized as having a density, surface tension, and viscosity configured to enable material jetting of the ink in contained, sequential droplets having a volume in the range of about 1 picoliter to about 1 nanoliter when jetted from a nozzle having an inner diameter in the range of about 10 microns to about 300 microns. A product, in accordance with another embodiment, includes a transparent ceramic, at least a portion of the transparent ceramic having layers of less than 50 microns per layer with physical characteristics of formation by material jetting.
