These manufacturing technologies promise resource-saving, tool-free production of almost any complex product with a high degree of flexibility in terms of size, quantity and material for a wide range of applications. The laser- and powder bed-based Laser Powder Bed Fusion (LPBF) process for the production of metallic functional components is of particular importance in this context. Due to the increasing industrialization of LPBF in recent years, the need for integration into an existing production environment based on conventional manufacturing technologies is increasing for economical production. As a result, the requirements for LPBF production machines are changing more and more, and the pressure on machine manufacturers to meet these requirements with suitable, economically reasonable machine technology is increasing. In order to fully exploit the economic and technological potential of LPBF and to establish it in production, the requirements of the product programs to be manufactured, as well as of the users and industries using these machines, must already be considered in the conception of new LPBF production machines. The aim of this thesis is therefore the development and validation of a application-oriented methodology for the systematic determination of requirements for the conception of industry- and application-specific LPBF production machines, taking into account production and economic indicators from the view of the machine operator. The focus is on the early phase of product development (in particular product planning, task clarification and conceptual design) in order to quickly evaluate inconsistent development paths and avoid redundant or contradictory activities. The methodology is thus intended to contribute to a reduction in effort and a concomitant shortening of the time-to-market for machine manufacturers. In addition to classic customer requirements, production (e.g. production efficiency) and economic (e.g. volume costs) indicators based on the product programs of the machine operator are also used for the focused development of the machine technology. The developed methodology serves the user on the one hand to simplify the decision-making process in the collection and selection of relevant customer requirements and differentiation from competitor products. On the other hand, the user can select suitable machine technology for the respective industry or application, thus contributing to the positioning of the customer in terms of production technology. %F PUB:(DE-HGF)11 ; PUB:(DE-HGF)3 %9 Dissertation / PhD ThesisBook %R 10.18154/RWTH-2023-00166 %U https://publications.rwth-aachen.de/record/861680
