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.

Kerstin Göpfrich and Daniela Duarte Campos receive the ERC Starting Grant 2022


Cluster PIs Kerstin Göpfrich and Daniela Duarte Campos are among the winners of the European Research Council (ERC) 2022 Starting Grant that is being awarded to excellent young scientists for their promising ideas and research projects. With this grant, Prof. Göpfrich funds her project "From engineering to evolution of synthetic cells with RNA origami" and Jun.-Prof. Duarte Campos her research on surgical optogenetic bioprinting of engineered cardiac muscle. The ERC is the premier European funding organisation for excellent frontier research and funds creative researchers of any nationality and age, to run projects based across Europe.

Christopher Barner-Kowollik
Christopher Barner-Kowollik awarded with two Medals


Principal Investigator Christopher Barner-Kowollik was awarded the David Craig Medal of the Australian Academy of Science as well as the HG Smith Medal of the Royal Australian Chemical Institute for his outstanding research on light as a "molecular surgical tool" for soft matter materials. His work fuses the in-depth understanding of chemical processes that are induced by light with their use to prepare soft matter materials, with applications from 3D printing inks to photodynamic materials. His research at QUT and KIT has enabled new material concepts, for example a dynamic material that is solely stabilised by light, and led to key advances in photochemistry.

New Public Lecture Series "3DMM2O"


On November 23, our new Public Lecture Series "3D Matter Made to Order" starts with a lecture by Principal Investigator Jochen Wittbrodt about the potential and limitations of Retinal Organoids. Within this series, different Cluster PIs explain the research in their groups and present previous successes to a wider audience. It takes place regularly on Wednesdays at the Centre for Organismal Studies at Heidelberg University from 4.30 pm to 6.00 pm. Participation online is possible after registration on the page linked below.

Stefanie Dehnen
Stefanie Dehnen becomes new Cluster PI


Prof. Dr. Stefanie Dehnen has been chosen as new Cluster Principal Investigator in Research Thrust A3! Since October 2022 she is Executive Director of the Institute of Nanotechnology (INT) at KIT and head of the research unit "Cluster-Based Materials". From 2006 until 2022 she was Professor of Inorganic Chemistry at the University of Marburg. This year she received the Gottfried Wilhelm Leibniz Prize and an ERC Advanced Grant for research on bismuth clusters and also became a member of the Berlin-Brandenburg Academy of Sciences and Humanities and Editor-in-Chief of the journal Inorganic Chemistry. We warmly welcome her to our Cluster!

Kerstin Goepfrich
Kerstin Göpfrich appointed as Professor at Heidelberg University


Cluster Principal Investigator Kerstin Göpfrich was recently appointed as W3 Professor by the Center for Molecular Biology Heidelberg (ZMBH). She will also be research group leader at the ZMBH with a focus on biophysical engineering of life. We congratulate her sincerely!

To the ZMBH
We welcome two new Cluster Associate PIs


We warmly welcome Prof. Dr. Jana Zaumseil and Dr. Jens Bauer as new Associate Principal Investigators in our Cluster! Jana Zaumseil is Professor for Applied Physical Chemistry and leads the research group "Nanomaterials for Optoelectronics" at the Heidelberg University. Jens Bauer is leader of the Emmy-Noether research group "Nanoarchitected Metamaterials" at the Institute of Nanotechnology of the KIT. We wish both of them a good start in our Cluster and look forward to productive collaboration.
