Abstract
A shaped ceramic or metallic object is formed by sectioning a model of a shaped body into 2-dimensional slices. For each slice, a toner material is electrostatically printed on a polymer sheet. The toner material includes solid particles. The printed sheets are assembled into a stack and the stack is depolymerized and sintered to form the ceramic object.
