Imagine a future where biological tissue can be printed directly inside the human body. This concept, once thought to be science fiction, is inching closer to reality thanks to the efforts of Dr. Andrea Toulouse at the Institute of Applied Optics, University of Stuttgart. Recently, she secured €1.8 million in funding from the Carl Zeiss Foundation to advance her research under the initiative called 3DEndoFab.
The goal of the 3DEndoFab project is to create a micro 3D printer capable of producing tissues within the body. Currently, while 3D printing technologies can fabricate skin, cartilage, and other cellular components, they typically require implants, which pose various complications. Dr. Toulouse aims to address this challenge by developing a fine 3D printer that can fit through the lens of an endoscope. This device would print tissue on-site, allowing it to function better as it integrates directly into existing biological systems.
The project, dubbed "3D Endoscopic Microfabrication," intends to engineer a micro-optic device no larger than a grain of salt, which would sit at the tip of an optical fiber. This device would manipulate light to enable high-resolution 3D printing of complex tissue structures at a micrometer scale. Envisioned to be inserted into the body in a manner akin to a syringe, this printing process prompts several questions, particularly around the administration of materials and the potential for non-invasive applications.
3DEndoFab embodies an interdisciplinary approach, merging engineering with biotechnology. Dr. Toulouse plans to collaborate with the Bionic Intelligence Tübingen Stuttgart (BITS) research network to facilitate transitions from laboratory to clinical environments, showcasing how additive manufacturing can transform modern medicine.
