Abstract

A method for the additive production of a ceramic main part has the following steps: providing a slip of ceramic base material particles suspended in a liquid phase; producing a slip layer; orienting the radiation of a laser light source onto a section of the slip layer; evaporating liquid phase out of the slip layer in the section of the slip layer onto which the radiation of the laser light source is oriented or was oriented; forming a section of the ceramic main part in the slip layer in a sinter-free manner; optionally repeating the steps of producing a slip layer, orienting the radiation, evaporating the liquid phase, and forming a section of the main part in a sinter-free manner until the ceramic main part is provided; and separating the ceramic main part from the slip.
