Joachim Messemer, M. Sc.

The doctorate's focus is on the scientific investigation and the development of competence in energy and resource efficiency through generative manufacturing processes. Innovative, generative production techniques of the entire manufacturing process from the idea to the finished component are examined. An enormous obstacle to the use of additive manufacturing processes is not only the high investment costs but also sensible and resource-efficient use. The technology requires a complete rethinking of the entire production process, which is why the consideration of energy consumption has been pushed into the background. Initial investigations on parts printed with plastic show potential optimization in the design and production machine. Also, geometries and designs can be produced that were previously only possible in simulations. Components can be produced pre-assembled, with integrated functions and taking into account force flow-oriented designs.

The Ph. D.'s innovative character is reflected in the investigation of heterogeneous groups of workpieces concerning energy and resource requirements. In previous studies, neither the research nor the application focus of generative manufacturing has been considering energy and resource requirements. The doctoral thesis, based on fundamental research in cooperation with the Technical University of Kaiserslautern, is intended to develop possible forecasting tools and statements on energy and resource consumption as early as the design/simulation phase. Besides, it is expected that the design parameters and generally valid specifications sought by industry can be developed, published, and disseminated in training courses.
