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.

3D Laser Nanoprinters Become Compact


Currently, 3D Laser Printers require big and expensive laser systems. Cluster researchers from KIT and Uni HD now present an approach to use two-step absorption with inexpensive and small, blue laser diodes instead of two-photon absorption to realize smaller, more compact printers. This could pave the way to make 3D laser printing accessible for a wider audience. The paper was published in the journal Nature Photonics.

Event Series "Successes & Challenges" starts at CAM


On November 16, the first "Successes and Challenges" event took place at CAM Heidelberg. Once a month, two presenters report on their successes while also highlighting their challenges to start a collaborative exchange with the audience. The first presenters were Tobias Spratte (AG Selhuber-Unkel) and Cluster Postdoctoral Researcher Lucie Zilova (AG Wittbrodt). The next event will take place on December 14, 03:15 p.m. at CAM and online.
