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.

"Exzellent Erklärt" episode published


In its most recent episode, the German science podcast "Exzellent erklärt - Spitzenforschung für alle" features the research of the Cluster of Excellence 3D Matter Made to Order (3DMM2O). In the episode, moderator Larissa Vassilian talks to Cluster Spokesperson and Principal Investigator Jochen Wittbrodt and his doctoral researcher Christina Schlagheck as well as Principal Investigator Peter Gumbsch in order to learn more about the Cluster research in the area of Organoids (Thrust C3) and Metamaterials (Thrust C2).
