Additionally, it is not possible to achieve tight dimensional tolerances or low surfaces roughness. Hence, a process chain has to be set up to combine additive manufacturing (AM) with further machining technologies. To achieve a continuous workpiece flow as basis for further industrialization of L-PBF, the paper presents a novel substrate system and its application on L-PBF machines and post-processing. The substrate system consists of a zero-point clamping system and a matrix-like interface of contact pins to be substantially connected to the workpiece within the L-PBF process.}, language = {en} } @article{WittBogner1990, author = {Witt, Klaus and Bogner, D.}, title = {Druckmessung mit zukunftsorientierten Perspektiven}, series = {Sensor Report. 5 (1990), H. 1}, journal = {Sensor Report. 5 (1990), H. 1}, isbn = {0179-9592}, pages = {8 -- 14}, year = {1990}, language = {de} } @article{WillmsBeerFroehlkeetal.1993, author = {Willms, Herbert and Beer, Stefan and Fr{\"o}hlke, K. and Haidn, O.J. and [u.a.],}, title = {Regelung eines Wasserstoff-/Sauerstoff-Dampferzeugers mit Hilfe eines modifizierten Zirkondioxid-Sensors}, year = {1993}, language = {de} } @book{WillmsBeer1993, author = {Willms, Herbert and Beer, Stefan}, title = {Regelung eines H2/O2-Dampferzeugers}, publisher = {DLR, Zentrale Allgemeine Dienste, Versand}, address = {K{\"o}ln}, pages = {116 S. : graph.

During handling operations of the powder material, several influencing factors can affect the properties of the powder material and therefore directly influence the processability during manufacturing. Contamination by moisture due to handling operations is one of the most critical aspects of powder quality. In order to investigate the influences of powder humidity on LPBF processing, four materials (AlSi10Mg, Ti6Al4V, 316L and IN718) are chosen for this study. The powder material is artificially humidified, subsequently characterized, manufactured into cubic samples in a miniaturized process chamber and analyzed for their relative density. The results indicate that the processability and reproducibility of parts made of AlSi10Mg and Ti6Al4V are susceptible to humidity, while IN718 and 316L are barely influenced.}, language = {en} } @inproceedings{WeingartSchneiderWollert2009, author = {Weingart, Daniel and Schneider, Ulf and Wollert, J{\"o}rg}, title = {Doppelt gekoppelt - Kabellose und dynamische Anbindung von CANopen an Profinet IO}, series = {Elektrische Automatisierung - Systeme und Komponenten: SPS-IPC-Drives 2009, Fachmesse \& Kongress, 24. - 26.
