摘要： The present invention relates to a method for additive manufacturing of a position sensitive colored ceramic article comprising: a) providing at least one flowable ceramic component; b) forming a green body by sequential deposition of the ceramic component provided in step a) and optionally a support material not intended to be part of the final article; c) position sensitive application of a coloring substance in a solvent to at least a part of the surface of the green body formed in step b), wherein the coloring substance is applied simultaneously to the sequential deposition; d) heat treatment or curing of at least a part of the green body surface obtained in step c); wherein the method steps a)-d) are at least performed once; e) optionally removing the support material from the green body; and f) sintering the green body to obtain the ceramic article; wherein the coloring substance is a dyestuff according to ISO 18451-1:2019(E). In addition, the present invention relates to a system adapted to perform the method and a control data set configured, when implemented in an additive manufacturing system, to cause the system to execute the steps of the inventive method.
