Abstract: The present invention relates to a method for the production of a photocurable formulation (F) for the use in an additive manufacturing process. In this method a ceramic dispersion (CD) comprising at least one ceramic material, at least one first acrylate 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 the inventive method and to a method for the production of a molding in an additive manufacturing process by curing the photocurable formulation (F). Moreover, the present invention relates to the use of the photocurable formulation (F) in an additive manufacturing process.
