摘要： 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 (2). Depositing is performed by a powdered material application device (1) and a binder application device (3). The two application devices (1 and 3) work in two mutually perpendicular directions along two horizontal planes parallel to each other and the worktop (2), performing the application in both directions of movement between their final positions. Application devices (1 and 3) 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. They reduce the time required to produce casting shapes and improve the accuracy, and also allow the generation of more complex shapes without the need for a physical model.

摘要： The invention relates to 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 (1) with a movable bottom (2), which is separated from the device for lifting and lowering (4) 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. This procedure is subsequently repeated until the entire volume is constructed, allowing direct casting in the resulting molds without removing them from the container (1), in which they are generated, after removing the unnecessary powdered material from their working cavities.
