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.

Cluster Young Scientist invited to Lindau Nobel Laureate Meeting


The Lindau Nobel Laureate Meetings aim at exchange between different generations, cultures and disciplines by bringing together Nobel Laureates and the next generation of leading scientists.This year, the Chemistry meeting takes place from June 26 to July 1. Cluster Young Scientist Clara Vázquez-Martel from the group of Principal Investigator Eva Blasco is one of the participants of this prestigious event.

Publication on Gear-Based Metamaterials


In a new paper published in Nature Materials, researchers including PI Peter Gumbsch show their research on metamaterials that can fully reconfigure their meta-atoms in a wide range, allowing direct access to anisotropies of different types. The approach is based on connecting classical gears, with the gear-based metamaterials providing excellent properties. This allows for metamaterial customization and brings fully programmable materials and adaptive robots within reach.
