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.

2020 OMEx Emerging Researcher Prize for Cluster paper


With the Optical Materials Express Emerging Researcher Best Paper Prize, the journal recognizes a student or early-career researcher who is the first author of a paper that a committee of OMEx editors judged to be outstanding. The 2020 prize goes to Simon Woska for his paper "Tunable photonic devices by 3D laser printing of liquid crystal elastomers". The author list includes several Cluster Young Researchers and Principal Investigators. Furthermore, the research was supported by the recently established CZF 3D User Lab.

Printed Thermoelectric Generators


Cluster scientists have developed a mass-producible low-cost fully printed flexible origami thermoelectric generator which is able to power an autonomous weather sensor comprising a Bluetooth module and a power management system. This approach might be a milestone for the use of low-cost TEGs. They present their results in the journal npj Flexible Electronics.

Interviews with Carl Zeiss Scholarship holders


The Cluster 3DMM2O has a lot of talented Young Researchers. In order two increase their visibility, we have published two interviews with female Carl Zeiss Foundation Scholarship holders Britta Weidinger (A3) and Tamara Molitor (C3). In the interviews, they talk about their research and the role of the CZF Scholarship Program for their academic career.
