Abstract
A method for producing a three-dimensional component having one or more cavities by powder-based additive manufacturing, such as selective laser melting or electron beam melting, using an additive manufacturing machine. The method includes creating 3D-CAD-data of the component to be produced using a computer-aided design method; b) identifying the cavities of the component in the 3D-CAD-data and verifying, that each cavity has at least one outlet passage connecting the cavity to the outer environment of the component, wherein, if there is no such outlet passage, it is created within the 3D-CAD-data; c) producing the component on a construction platform of the additive manufacturing machine on the basis of the 3D-CAD-data; d) removing powder present within the cavities and within the outlet passages through the outlet passages and e) heat-treating the construction platform and the component arranged thereon in a heat treatment oven.
