OG exemplary drawing
 
1. A device for producing components comprising a mold building device for producing lost casting molds, and a casting device connected to the mold building device for casting the components in the lost casting molds,
wherein the mold building device is configured for the continuous layering of molding plates, wherein a respective at least three of said molding plates form a lost casting mold of the lost casting molds,
wherein the mold building device is configured to at least temporarily change a stacking direction in such a way that a vertical stack of molding plates is adjacent to a horizontal stack of molding plates.
 
6. A method for producing castings, in which first molding plates are produced and automatically continuously layered in a mold building device, a respective casting mold being formed by at least three molding plates delimiting a common cavity, wherein a stacking direction is at least temporarily changed and a vertical layer stack of molding plates is rotated by 90 degrees after it has been layered and is joined together with further mold elements, and a casting material then being poured into the casting molds within a casting device connected to the mold building device.
