Voronoi Toolpaths for 3D Printed Lung Tissue Scaffolds

Researchers from Politecnico di Torino and Maastricht University have pioneered a novel computational design tool specifically for 3D printing lung tissue models. This software, known as PyVoroGen, utilizes Voronoi geometries to create irregular, biomimetic scaffolds that traditional slicing programs cannot easily produce. By combining extrusion-based printing with electrospun membranes, the team successfully replicated the complex alveolar-capillary barrier for laboratory testing. Their hybrid constructs supported the simultaneous growth of epithelial and endothelial cells, effectively mimicking the structure of human lungs. This advancement offers a more physiologically accurate platform for medical research and drug testing by moving beyond simple, repeating shapes. Ultimately, the study provides a standardized framework for integrating natural biological complexity into additive manufacturing workflows.
