Revolution in biomedicine: Discover new materials for 3D printing!

On March 8, 2025, there are promising developments in biomedical engineering presented by Dr. Johannes Gurke, head of the “Applied Photochemistry and 3D Bioelectronics” working group at the University of Potsdam. His research focuses on developing new materials made by applying light in chemical reactions known as photochemistry. These innovative approaches are supported by financial support from the Federal Ministry of Education and Research (BMBF) amounting to almost 2.5 million euros, which underlines the importance and potential of these technologies.

The main goal of Dr. Gurke's team is producing electrically conductive materials from viscous resin, which are to be manufactured using 3D printing technologies. This opens up new possibilities in bioelectronics, particularly in the precise measurement of electrical signals in biological systems such as nerves and the heart. The long-term plan is to develop biomedical products that can be tailored to specific brain regions and individual patient needs. These research efforts are supported by the BMBF's “NanoMatFutur” young talent competition and a second project in the “KMU innovative” program in collaboration with xolo GmbH.

Innovative printing techniques in biomedical engineering

xolo GmbH has developed a novel 3D printing technique called xolography that combines two beams of light. This technique allows to create biocompatible materials with complex geometries and aims to use the technology in drug development. In addition, the work of Dr. Gurke is driven by scientific advances in additive manufacturing and the development of polymers. Institutes such as Fraunhofer IAP have specialized in developing polymer materials for this sector that have elastic and biomimetic properties.

The quality of these materials is crucial for creating customized prostheses and implants tailored to specific patient injuries. For example, isolation capsules for soft tissue dislocations can be designed to promote tissue perfusion. Fraunhofer IAP's approach highlights the importance of using high-quality materials that meet strict medical requirements.

Sustainable approaches in material development

Another important aspect in the development of these materials is the use of sustainable chemistry. The researchers are working on producing biodegradable implants and those made from renewable raw materials in order to avoid toxic or critical raw materials. These sustainable solutions support the increasing demand for ecologically responsible technology that pursues not only medical but also environmentally friendly goals.

In summary, the collaboration between institutions and companies shows how the innovative use of light and 3D printing technologies is creating new perspectives in medical technology. The developments of Dr. Gurke and his team at the University of Potsdam are just a few examples of advances that could have a significant impact on the future of biomedical products. At a time when innovative solutions are becoming increasingly important, these projects are at the forefront of technological change in medicine.
