BOGDÁN Preface The 4th International Interdisciplinary 3D Conference is a route leaving event in the series since this is the first time the conference is divided to sections which are held on separate locations. Our Faculty of IT and Engineering of University Pecs is proud to be organizer of the event, while the topic is fully intertwined with our goals. In March of 2018, the 3D Printing Center on the Faculty has been opened and the science of these cutting-edge technologies couldn’t be closer to our daily life since then. Researchers, teachers, students can use devices, whose can scan 3D objects, or print their project works with technologies of SLS, polyjet, FDM, etc., which is a great experience especially for students who wants to materialize their final projects or a regular design study of a building or mechanism. These technologies are useful for all disciplines therefore it was also a must to make our projects transparent and show the achievements of this part of science. This is the aim which serves this conference and fair event, where the researchers, developers, makers can show up and change their knowledge, make new contacts. It was hard during the organization, to fully separate biotechnology from engineering, while the topic of the conference assumes to be around the technologies of 3D visualization, 3D sensing (vision) and 3D printing. These technologies are utilized in engineering which have proved to could used in various parts of medicine, biotechnology since engineering can give and maintain the technical background for researchers from other disciplines. Although the other section biotechnology is only a tight area of medicine, it was hard not to include topics from the border areas. The proof of the closing areas is that a bioengineering curriculum is being developed and accredited in the cooperation of Medical and the Engineering Faculty. The future plans are to keep up with the organization of the conference, widen the impact of the fair and involve more researchers worldwide. In the name of the organizers I wish a nice and grateful experience on the conference and exhibition!
