Abstract
Methods of forming three-dimensional metallic objects are provided. A metal oxide paste comprising metal oxide particles, a polymeric binder and an organic solvent is extruded through a tip to deposit sequential layers of the metal oxide paste on a substrate to form a three-dimensional metal oxide object. The three-dimensional metal oxide object is exposed to a reducing gas at a temperature and for a period of time sufficient to reduce and to sinter the metal oxide particles to form a three-dimensional metallic object. Depending upon the composition of the metal oxide paste, the three-dimensional metallic object may be composed of a single metal, a simple or complex metal-metal alloy, or a metal-ceramic composite.
