In this method a ceramic dispersion (CD) comprising at least one ceramic material, at least one first acrylate N and at least one dispersant is mixed with a solution (S) which comprises at least one second acrylate and at least one photoinitiator to ---. obtain the photocurable formulation (F). The present invention furthermore relates to the photocurable formulation (F) obtainable by I N the inventive method and to a method for the production of a molding in an additive manufacturing process by curing the photocurable 1-1 © formulation (F). Moreover, the present invention relates to the use of the photocurable formulation (F) in an additive manufacturing ei process. C
