Introduction RTI – Regional Technological Institute, a research center of the Faculty of Mechanical Engineering of the University of West Bohemia in Pilsen, has been engaged in R&D of additive technologies for more than 10 years. RTI has high-quality facilities for printing test samples and components using the SLM method (2 x EOS M290, 1 x EOS Abstract RTI – Regional Technological Institute, a research center of the Faculty of Mechanical Engineering of the University of West Bohemia in Pilsen, has been engaged in research and development of additive technologies for more than 10 years. Research and development of additive manufacturing of metals is the flagship of RTI in the field of international cooperation. And the development of international cooperation is also one of the monitoring indicators of a new project with the acronym RTIdigi. In the first part, the contribution provides an overview of several R&D projects that were implemented in cooperation with RTI's foreign partners. In the second part, the first findings from the chosen approach to using machine learning for quality management in additive manufacturing, based on outputs from in situ monitoring of the printing process, are presented. The fourth European Conference on the Structural Integrity of Additively Manufactured Materials (ESIAM26) Research and development of additive manufacturing at the RTI research center implemented in international cooperation - overview and main outputs, including ML activity Miloslav Kepka a, *, Adam Polansky a a University of West Bohemia, Faculty of Mechanical Engineering, Regional Technological Institute, Univerzitni 2732/8, 301 00 Pilsen, Czech Republic
