Abstract
A method for producing a pattern for the precision-cast representation of a component having a cavity is provided. In the method wherein the component is a turbine component having a cavity, the finished pattern comprises a core and an outer contour pattern, the outer contour pattern at least partially surrounds the core and at least partially defines the outer contour of the turbine component. The core is produced from a curable core material, which cures during the course of the method, and the outer contour pattern is produced from a material which can be burned or melted out. In this case, first the outer contour pattern is produced with a cavity corresponding to the cavity of the turbine component and subsequently the curable core material is filled into the cavity and cured to produce the core.
