3D Additive Manufacturing Driven Towards the Molecular Scale

The Cluster of Excellence is a collaboration of Karlsruhe Institute of Technology (KIT) and Heidelberg University (Uni HD). It pursues an interdisciplinary approach through conjunction of natural, engineering, and social sciences. 3DMM2O establishes scalable digital 3D Additive Manufacturing transcending from the molecular to the macroscopic scale.

This approach converts digital information into functional materials, devices and systems “made to order.” 3DMM2O creates a powerful technology push and pull by treating molecular materials, technologies and applications as indissolubly intertwined.

On the technology side, the scientific challenges are “finer, faster, and more”, i.e., advance molecular materials and technologies in terms of resolution, speed, and multi-material printing by orders of magnitude.

On the application side, we aim at functional 3D hybrid optical and electronic systems, 3D artificial materials called metamaterials, and at reconstructing functioning organotypic systems by using 3D scaffolds for cell culture.

Hector Seminar Pupils Explore 3D Food Printing


On July 7, pupils from course KA 16 of the Hector Seminar explored the versatile possibilities offered by 3D food printers. Under the guidance and supervision of Cluster Young Scientists Saskia Braun, Maximilian Elter, Clara Vázquez-Martel and Pascal Kiefer, they learned the theoretical and practical basics of designing and printing with mashed potatoes, pasta dough and chocolate.

Cluster PIs Involved in Successful NFDI Consortia


On July 2, the Gemeinsame Wissenschaftskonferenz (GWK) decided the inclusion of ten additional consortia within the Nationale Forschungsdateninfrastruktur (NFDI). Among the new consortia supported in this second funding round are NFDI-MatWerk (Materials Science and Engineering) and FAIRmat (Condensed-Matter and Chemical Physics of Solids). Cluster PIs Peter Gumbsch and Ruth Schwaiger are members of NFDI-MatWerk and Christof Wöll is a member of FAIRmat.

Freestanding Walls of Water


A team of researchers that includes Cluster Young Scientist Mariia A. Kuzina and Principal Investigator Pavel A. Levkin presents a new way to contain fluids without a wall using so-called "liquid wells". The authors conclude that the water walls are self-repairing, adaptive and functional, thus displaying properties that are uncommon when it comes to solid walls. Their research was published in the journal Advanced Materials.

Bridging Top-Down and Bottom-Up Approaches in Synthetic Biology


In a new paper published in Nature Communications, a group of researchers including Cluster Young Scientist Kevin Jahnke and Principal Investigators Rasmus R. Schröder, Joachim Spatz and Kerstin Göpfrich demonstrate that the use of top-down engineered bacteria can enhance bottom-up assembled synthetic cells, thus providing a vision to bridge the gap between the two approaches in synthetic biology.

Launch of Research Data Management Online Course


Research Data Management is an important aspect of the research conducted in the Cluster of Excellence 3D Matter Made to Order (3DMM2O). In order to provide Young Researchers with the necessary tools and knowledge, a recently launched online course by the Cluster introduces good scientific practice of research data handling in an interactive way including practice-oriented examples.
