The increasing complexity of products requires efficient computer-aided methods and tools in product development. Data and information from quality assurance, such as industrial computed tomography (iCT), are increasingly being used. With this technology it is possible to detect 3D information of internal structures and geometries and to use it for design and numerical issues within the product development. The previous procedure for use CT data in the product development comprises several iterative step sequences. Starting first from an image stack a discrete model description, such as a STL file format (Standard Tessellation Language) is created. This data description can be used for numerous applications in the product development such as target-actual comparison in the component inspection. For information, which also exist during entry (f.e. production faults), there is no established process sequence. However, the characteristics on the errors can also contain causes for defects and should therefore take into account in product development. For this reason, a concept is presented in the following article to use CT data and additional information specifically for the product development. Using a continuous process chain between quality management (QM) and the product engineering this approach should be clarified. To integrate the description and characterization of the information an already existing standard will be used and extended accordingly. An essential application of this approach is the component testing of additive manufactured parts by CT within the product development process. The combination of this Non-Destructive Testing (NDT)-Technology with the advantages of additive manufacturing processes such as the creation of internal structures makes a continuous process chain unavoidable. For this reason, an example of an additively manufactured impeller clarifies the approach.
