Method and device for the manufacturing of ceramic bodies

摘要

Production of ceramic molded bodies comprises applying a layer of a liquid suspension or plastic composition; drying the layer; and sintering the dried layer using a laser beam on selected sites to form the molded body. An Independent claim is also included for a device for the production of ceramic molded bodies comprising a support surface (4), a unit for applying layers of ceramic material in the form of a liquid suspension or plastic composition on the support surface, a drying unit (6) for the applied layers, and a laser unit (3) for producing a laser beam with devices for directing the beam onto selected sites of each layer to sinter the laser-radiated material and form the molded body. Preferred Features: The ceramic material is aluminum oxide, porcelain powder, highly pure silicic acid, aluminum nitride, silicon or silicon nitride.
