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.

Although many research groups focus on digital twins and create meaningful outputs, the technology has not yet reached a broad application in the industry. The main reasons for this imbalance are the complexity of the topic, the lack of specialists, and the unawareness of the twin opportunities. The project "Digital Twin Academy" aims to overcome these barriers by focusing on three actions: Building a digital twin community for discussion and exchange, offering multi-stage training for various knowledge levels, and implementing realworld use cases for deeper insights and guidance. In this work, we focus on creating a flexible learning platform that allows the user to select a training path adjusted to personal knowledge and needs. Therefore, a mix of basic and advanced modules is created and expanded by individual feedback options. The usage of personas supports the selection of the appropriate modules.}, language = {en} } @inproceedings{UlmerLaiChengetal.2019, author = {Ulmer, Jessica and Lai, Chow Yin and Cheng, Chi-Tsun and Wollert, J{\"o}rg}, title = {Integration von VR und AR in Produktlebenszyklen - Eine {\"U}bersicht {\"u}ber die Nutzung virtueller Technologien im industriellen Umfeld}, series = {Automation 2019}, booktitle = {Automation 2019}, pages = {1 -- 12}, year = {2019}, language = {de} } @inproceedings{UlmerBraunWollert2018, author = {Ulmer, Jessica and Braun, Sebastian and Wollert, J{\"o}rg}, title = {Generische IoT Adapter f{\"u}r semantische Maschinenschnittstellen}, series = {Internet of Things - vom Sensor bis zur Cloud}, booktitle = {Internet of Things - vom Sensor bis zur Cloud}, pages = {1 -- 5}, year = {2018}, language = {de} } @inproceedings{UlmerBraunWollert2021, author = {Ulmer, Jessica and Braun, Sebastian and Wollert, J{\"o}rg}, title = {Adaptive VR-Produktionsumgebungen f{\"u}r Evaluations- und Schulungst{\"a}tigkeiten}, series = {Automation 2021: Navigating towards resilient Production}, booktitle = {Automation 2021: Navigating towards resilient Production}, publisher = {VDI}, address = {D{\"u}sseldorf}, isbn = {978-3-18-092392-5}, issn = {0083-5560}, doi = {10.51202/9783181023921-55}, pages = {55 -- 64}, year = {2021}, abstract = {Industrie 4.0 stellt viele Herausforderungen an produzierende Unternehmen und ihre Besch{\"a}f-tigten.
