This study aims to present approach of the accuracy improvement of the reconfigurable facet molds process for rapid prototyping of casting parts using FEM simulation. Simulation will allow predicting thermal distortions and to rescale the 3D model put in account different scale factors in different directions in virtual phase. In the initial 3D geometry targeted to reach maxim value of accuracy of final molding components. The results obtained were implemented for small lots of nonferrous metal
