3D Matter Made to Order

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.

Enzyme-Degradeable Photoresist

A new paper published in Advanced Functional Materials, introduces a biocompatible and photocurable resist for scaffold fabrication that can be readily degraded by a certain enzyme. The authors, among them Cluster PIs Eva Blasco, Martin Wegener and Christopher Barner-Kowollik, describe their photoresist as a step towards "enabling 3D tissue constructs to be created to heal patients with tissue loss or to guide tissue regeneration".

Microstructures for Cell Stress Testing

Researchers of the Cluster 3DMM2O developed a new method to analyze the impact of external forces on singular cells by creating microstuctures using 3D printing to stretch the cells. The scientists were able to observe how different cells counteract or give in to the pressure.

The paper describing the method was published in the journal Science Advances.

New photoresist enables 3D printing of nanoporous structures

In a paper recently published in the journal Advanced Materials, Cluster researchers describe a newly developed photoresist for 3D laser microprinting that can be used for manufacturing nanoporous polymer microstructures. By tuning the writing parameters, the porosity of the printed material can be controlled.
