On 02.03.2023 the "ACstyria LEICHTBAUTAG 2023" took place in cooperation with the A2LT at the Red Bull Ring. The most current topics in lightweight engineering, such as lightweight construction aspects in additive manufacturing, the importance of lightweight design, sustainable composites and other aspects were discussed. The TCKT was also able to use this platform to show results from current research. Our presentation on sustainable composites was followed with interest and was thought-provoking. In addition to the good presentations, there was also good networking. A thoroughly successful event!
