Method of Making Ceramic Discharge Vessels Using Stereolithography

摘要

A method of manufacturing a ceramic discharge vessel for a lamp application is described. The method uses a low viscosity suspension of ceramic powder in a liquid resin. The discharge vessel is formed layer by layer using a stereolithography system. Preferably, the layers are formed by locally exposing the ceramic-resin mixture to a UV light source that solidifies and cures the resin only in the areas which correspond to the particular cross-sectional profile of the discharge vessel for a respective layer.
