On September 30, 2025, our members gathered at the University of Heidelberg for this year’s Summer Cluster Meeting. The program included a general assembly with an overview of the upcoming 3DMM2O Conference 2026: Frontiers in Theory, Computation, and Design of 3D Materials, as well as scientific presentations. A newly introduced interactive smartboard session offered a dynamic way to exchange ideas across research areas. During coffee breaks, lively discussions continued, bringing fresh perspectives to the day. The focus was on the structures and projects of the second funding period, providing common ground for discussion and planning. The meeting also offered opportunities for networking and informal exchanges, strengthening connections within the community. It concluded with a sense of collaboration and excitement for the projects ahead.
