Abstract: A method for direct casting of cast components by layer-wise generation of composite molds, wherein the composite molds are generated as monolithic elements and simultaneously with their respective cores in an assembled form. The system for layer-wise generation of three-dimensional models from the powdered material in a removable container with a movable bottom, which is separated from the device for lifting and lowering the movable bottom, which is built into the system for layer-wise generation of three-dimensional models. The generation of the molds is done by application of layers of powdered material and binding of the particles of each layer through a binder, added selectively according to a program/pattern only in the volumes, where the solid body of the model is being generated.

Abstract: The method and system for layer-wise generation of three-dimensional objects from powdered material includes sequential application of powdered material and suitable binder onto a vertically mobile worktop. Depositing is performed by a powdered material application device and a binder application device. The two application devices work in two mutually perpendicular directions along two horizontal planes parallel to each other and the worktop, performing the application in both directions of movement between their final positions. Application devices move and deposit the respective substance at a different optimal rate depending on the process. The method and the system have a wide range of applications in the casting industry for the layer-wise generation of complete sand molds and/or high precision cores directly from a three-dimensional computer model.
