A method for direct casting of cast components by layer-wise generation of composite molds comprising the following successive stages: - a stage of layer-wise generation of composite molds comprising multiple sequential application of a powdered material and of a suitable binder onto a vertically movable worktop in a system for layer-wise generation of three-dimensional objects from a powdered material, where the application of the binder is carried out following a preset pattern over a subsequent layer of the molds being generated, and the said worktop is a vertically movable bottom of a removable container for direct casting, located in a work area of the system, wherein onto said movable bottom are generated one or more non-detachable monolithic composite molds with or without integration of one or more cores; - a stage of lowering the movable bottom in a lower position, after the generation of the said one or more molds in the event that at the preceding stage of generation of the composite molds the entire working height of the removable container was not used; - a stage of removal of the removable container for direct casting with the already generated one or more molds from the work area of the system for layer-wise generation of three-dimensional objects from a powdered material; - a stage of removal of excess unbound powdered material from working cavities of said one or more molds, which are thus prepared for direct casting into the removable container for production of cast components; - a stage of direct casting in said one or more molds without removing them from said removable container; - a stage of removing the cast components from said container after they are cooled down and subsequent cleaning of residual powdered material; - a stage of final removal of the sprue systems, feeder heads, and other elements of the cast components until the desired cast element is obtained. - a stage of layer-wise generation of composite molds comprising multiple sequential application of a powdered material and of a suitable binder onto a vertically movable worktop in a system for layer-wise generation of three-dimensional objects from a powdered material, where the application of the binder is carried out following a preset pattern over a subsequent layer of the molds being generated, and the said worktop is a vertically movable bottom of a removable container for direct casting, located in a work area of the system, wherein onto said movable bottom are generated one or more non-detachable monolithic composite molds with or without integration of one or more cores; - a stage of lowering the movable bottom in a lower position, after the generation of the said one or more molds in the event that at the preceding stage of generation of the composite molds the entire working height of the removable container was not used; - a stage of removal of the removable container for direct casting with the already generated one or more molds from the work area of the system for layer-wise generation of three-dimensional objects from a powdered material; - a stage of removal of excess unbound powdered material from working cavities of said one or more molds, which are thus prepared for direct casting into the removable container for production of cast components; - a stage of direct casting in said one or more molds without removing them from said removable container; - a stage of removing the cast components from said container after they are cooled down and subsequent cleaning of residual powdered material; - a stage of final removal of the sprue systems, feeder heads, and other elements of the cast components until the desired cast element is obtained.
