Additive Manufacturing (also: 3D printing, AM) enables manufacturing companies to react quickly to changes in global competition. From the end user’s point of view, the design data of 3D-printed components is particularly worthy of protection, since a significant proportion of the added value is already created in the design of the components. If the service provider knows the relevant material-specific process parameters, the manufacturing process itself is merely an enabling function, which reduces the depth of added value in this process step. Up to now, the component data for 3D printing has been sent digitally to the manufacturer, usually an external service provider. The latter is then responsible for the process of so-called data preparation, i.e. the compilation of several components into a production order as well as the corresponding further processing and preparation for the printing process. Even with secure transmission, it is possible that the data could be compromised or used for unauthorized production of similar parts. Since all steps from the design to the production of the components are extremely knowledge-intensive, the required respective know-how along the process chain serves as a unique selling point for the end customer, equipment manufacturer and service provider and is accordingly worth protecting.
