Thanks to numerous continuous steps forward and improvements RP processes found more and more applications in daily engineering practice. One of area that has significant potential is direct production by 3DP process of ceramic based tools for casting of nonferrous alloys, also known as a ZCast.  Due to the specificity of production of objects by 3DP process there are certain smaller or larger dimensional deviations of produced parts from the original 3D CAD model. In this paper is presented an analysis of dimensional deviations of 3DP parts produced for ZCast application with the aim to determinate value of anisotropic scaling factor and post-processing parameters and achieving of adequate dimensional accuracy of produced 3DP ZCast tools.
