Abstract

The invention relates to a method for generatively producing a dental molding for at least one of dental restoration and dental prostheses. The method comprises the following steps: a) providing at least one layer of a dispersion, particularly an aqueous dispersion, wherein the dispersion comprises at least one binder, and wherein the dispersion comprises ceramic particles and/or glass ceramic particles and/or powder metal particles; b) applying hardeners to the layer of dispersion in places for activating the at least one binder for hardening the layer of the dispersion in places, whereby a rough blank is obtained, particularly a green body, wherein at least two hardeners having different material composition from each other are used; and c) sintering the rough blank into the dental molding.
