It is clear that these advances will continue to be shaped by cutting-edge research from across this field. As a discipline, materials science has rapidly grown in profile as one of the most vibrant and pioneering areas of study, resulting in substantial growth in the numbers of published articles and associated research materials. In order to expedite these discoveries and maximize their impact, ensuring the availability of open and reproducible materials science research is vitally important, as well as embracing the opportunities provided by emerging cross-disciplinary fields such as artificial intelligence. The open sharing of materials research and data can encourage further exploration, improving collaboration between researchers and, ultimately, accelerating the discovery, design, and deployment of new materials as well as new business models. Materials Open Research, a new publication venture from publishers F1000 and Taylor & Francis, has been conceived and launched with these principles in mind. All research shared on the platform will aim to provide impact, nurture innovation, and lead to a more sustainable future.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41504700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In most of the previous works, the focus in process monitoring and control was on the control of energy input, by controlling the properties of the melt pool. However, the powder mass input is as important to monitor as the energy input, in order to preserve the equilibrium of the process. Methods: In this paper, the authors present the first test results of the Pyzoflex® sensor for powder flow monitoring in L-DED using real powder feeding system in the robot-based laser-processing cell. The sensor was tested against the powder projected from the powder feeder under typical flow regimes and the real-time measurements were taken using a specifically designed software tool. Results: The graphical representation of the registered sensor signals are clearly correlated with the powder flow values set at the powder feeder, which demonstrates that the piezoelectric sensors can detect the powder flow with elevated precision in real time. Conclusions: The first laboratory tests of flexible printed piezoelectric sensors demonstrate that they are fast and precise in the powder flow measurement, but that more effort must be invested in the robustness of the measurement setup as well as in clearing and stabilization of the registered signal.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49402068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
