PROBLEM TO BE SOLVED: To provide a method for producing parts, in particular, the parts having a shape of a casting mold or a core by the deposition method. SOLUTION: A multi-layered composite material is formed for each layer. Each layer contains a granular material, a binder and an optional processing agent. Each layer has the predetermined porosity. The binder can be hardened, in particular, with liquid hardening agent. The multi-layered composite material is formed without using any hardening agent. After the multi-layered composite material is completed, the multi-layered composite material of the predetermined part is filled with the liquid hardening agent by utilizing the remaining porosity, and the multi-layered composite material is hardened thereby.
