More than 200 participants learned about the latest trends in materials technology over two days on February 25/26 at the Materials Technology Symposium. Both the industrial and the research side of the topic were examined. The special Clausthal "care package" ensured a real conference atmosphere at the online event.
In his welcoming remarks, Prof. Joachim Schachtner gave a brief overview of the highlights of the program and outlined the circular economy as the new mission statement of Clausthal University of Technology. Plastics can also make an important contribution to the aspect of sustainability, as Guido Frohnhaus from Arburg addressed in his subsequent keynote speech "Challenges in the plastics industry". However, this requires a cross-industry, fact-based discussion that goes beyond science. As a technical example of the sustainable use of plastics, he presented, among other things, that recyclates, i.e. recycled plastics, can already be used on a large scale in certain component areas (e.g. without color fastness requirements).
The second keynote lecture by Prof. Norbert Enzinger from Graz University of Technology was dedicated to the topic of 3D printing of metals using wire arc additive manufacturing (WAAM), i.e. metal inert gas welding. Metal powder-filled welding wires were investigated to specifically influence the material composition and the associated adaptation of the material properties. In contrast to plastics, 3D printing of metallic materials with high deposition rates is not fully established according to the state of the art. Contributions from Clausthal also dealt with this highly topical subject, e.g. the generation and properties of multi-material structures, metrological aspects with regard to component distortion and process control techniques using artificial intelligence methods.
In addition to 80 specialist presentations, participants were also able to attend a virtual poster show and demonstrator exhibition of the Lower Saxony innovation network GROTESK "Generative Manufacturing of Optical, Thermal and Structural Components", e.g. on the construction of lasers. The partners here are TU Clausthal, Leibniz Universität Hannover, Hannover University of Applied Sciences and Arts and the Laserzentrum Hannover.
As it was not possible to hold the event in person, all participants were sent a Clausthal "care package" in advance, as Prof. Maus-Friedrichs, CZM Board Spokesman, called it in his welcoming address. In addition to all the conference utensils, it also contained some culinary resin specialties to at least create a certain genuine conference atmosphere. According to the feedback from some of the participants, this was also present at the latest during the evening lecture by Prof. Martin Korte from the TU Braunschweig on the subject of "Lifelong learning".
Prizes for particularly successful presentations were awarded to 3 speakers. Mr. Benedikt Dorbath from the Friedrich-Alexander University Erlangen-Nuremberg from the Chair of High Frequency Technology. He presented new wireless sensor concepts with which the curing processes in epoxy resins and fiber composite components can be detected in-situ. Mr. Tobias Grabe from the Institute for Product Development and Device Engineering at Leibniz Universität Hannover was awarded for his contribution to the modelling of thermomechanical effects in the additive manufacturing of glass waveguides. Dr. Manel Ellouz from the Laboratory for Materials Testing at Bielefeld University of Applied Sciences and Arts also received an award for her presentation on the computed tomography examination of an automotive chassis hybrid component consisting of aluminum and CFRP.
To conclude, Dr. Henning Wiche looked ahead: "We expect all guests to be present again at the Materials Technology Symposium in February 2023 in the best Harz winter weather. What's more, the 5th Materials Technology Symposium will be a small premiere, and guests can certainly look forward to a surprise or two.
