When spare part obsolescence occurs, quick solutions are needed. A reproduction of obsolete parts is often connected to long waiting times and minimum lot quantities that need to be purchased and stored. Spare part storage is therefore challenged by growing stocks, bound capital and issues of part ageing. A possible solution could be a virtual storage of spare parts which will be 3D printed through additive manufacturing technologies in case of sudden demand. As mechanical properties of additive manufactured parts are neither guaranteed by machine manufacturers nor by service providers, the utilization of this relatively young technology is impeded and research is required to address these issues. This paper presents an examination of mechanical properties of specimens manufactured from stainless steel through the selective laser melting (SLM) process. The specimens were produced in multiple batches. This paper interrogates the question if the test results follow a normal distribution pattern and if mechanical property predictions can be made. The results will be put opposite existing threshold values provided as the industrial standard. Furthermore, probability predictions will be made in order to examine the potential of the SLM process to maintain state-of-the-art mechanical property requirements.}, language = {en} } @inproceedings{GabrielliMathiesGrossmannetal.2015, author = {Gabrielli, Roland Antonius and Mathies, Johannes and Großmann, Agnes and Herdrich, Georg and Fasoulas, Stefanos and Middendorf, Peter and Fateri, Miranda and Gebhardt, Andreas}, title = {Space Propulsion Considerations for a Lunar Take Off Industry Based on Regolith}, series = {International Symposium on Space Technology and Science (ISTS).
