Additive Manufacturing technologies are based on a layer-by-layer build-up. This offers the possibility to design complex geometries or to integrate functionalities in the part. Nevertheless, limitations given by the manufacturing process apply to the geometric design freedom. These limitations are often unknown due to a lack of knowledge of the cause-effect relationships of the process. Currently, this leads to many iterations until the final part fulfils its functionality. Particularly for small batch sizes, producing the part at the first attempt is very important. In this study, a structured approach to reduce the design iterations is presented. Therefore, the cause-effect relationships are systematically established and analysed in detail. Based on this knowledge, design guidelines can be derived. These guidelines consider process limitations and help to reduce the iterations for the final part production. In order to illustrate the approach, the spare parts production via laser powder bed fusion is used as an example.

Hip joint arthroplasty is considered to be a safe, successful and cost-effective procedure to restore hip joint functionality. However, a successful hip joint arthroplasty affects different stakeholders e.g. patient and surgeon and depends on various influencing factors within the product life cycle as well as the applied technological opportunities. Due to the complex dependencies between influencing factors, technological opportunities and stakeholders, this contribution introduces an IPD-based approach to improve the quality of total hip arthroplasties.
