Abstract
Ceramic molds are produced by sintering selected portions of a ceramic material with a laser beam to form the mold. The process involves application of at least one layer of a liquid suspension or plastic mass, drying the applied layer, and sintering the dried layer with the laser beam at selected areas to form the mold.
