More InformationThe 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.

3DMM2O Secures Second Funding Period
We are proud to announce that our Cluster of Excellence 3D Matter Made to Order (3DMM2O) has secured funding for a second period through the German Excellence Strategy. Following the submission of our renewal proposal in August 2024 and a successful on-site evaluation in January 2025, this achievement represents a significant milestone in our ongoing commitment to advancing 3D Additive Manufacturing at the intersection of technical and life sciences. 3DMM2O will now begin on a new chapter filled with innovative research projects and interdisciplinary collaboration. We extend our heartfelt thanks to all who made this success possible.

Tunable Hydrogels for 4D Printing
In a new publication, Principal Investigator Eva Blasco, Cluster Alumnus Christoph Spiegel, and H. B. Duc Tran developed a new class of smart hydrogel inks based on OEGMA for 4D microprinting. They created materials with tunable thermoresponsive behavior across a broad temperature range (33–66 °C) by combining OEGMA with MEO2MA and HEMA, surpassing traditional systems. Using two-photon laser printing, the researchers produced precise 3D microstructures that change shape predictably and reversibly with temperature. This breakthrough opens new possibilities for soft microrobotics, smart sensors, and biomedical microdevices.
A Review of Nonlocal Metamaterials and Metasurfaces
A new review article featuring Cluster Postdoctoral Researcher Yi Chen and PI Martin Wegener, published in Nature Reviews Physics, explores the concept of nonlocality in metamaterials and metasurfaces. Unlike traditional materials, which have local responses, nonlocality enables a material’s behavior to depend on fields at multiple locations. This unlocks novel ways to control wave propagation across optics, acoustics, elasticity, and diffusion. The review highlights surprising phenomena, like unusual wave dispersion, long-range static effects, and spatially tailored responses in thin metasurfaces. These effects can be engineered using classical building blocks, paving the way for advanced applications in compact, wave-based technologies, like mobile devices and optical neural networks.
Explore the World of 3D Printing: A free Summer Workshop for Girls
Are you curious about turning ideas into real, usable objects? Our 2025 Summer 3D Printing Workshop for Girls is the perfect place to start! This free, hands-on workshop will be held on August 6–7 at the ZEISS Innovation Hub on the KIT Campus North in Karlsruhe. Girls and young women aged 13 to 19 are invited to attend and learn about the exciting world of 3D printing. Participants will learn to sketch ideas, model them in Fusion 360, and bring their designs to life with 3D printers. Whether you dream of creating keychains, phone stands, or something entirely unique, this is your chance to bring your imagination to life.
The Manfred Fuchs Prize 2025 awarded to Prof. Dr. Pascal Friederich
Pascal Friederich, our Cluster PI from the Karlsruhe Institute of Technology (KIT), has been awarded the Manfred Fuchs Prize 2025 by the Heidelberg Academy of Sciences. The €10,000 prize recognizes early-career researchers in Baden-Württemberg who bridge disciplines and drive scientific innovation. Friederich’s research combines artificial intelligence with materials science to accelerate the discovery and simulation of new materials, which is crucial for green energy technologies and pharmaceutical innovations. His data-driven approach is helping redefine the design of future materials.
