Surgeons and doctors often rely on artificial models to practice delicate procedures. Researchers at the University of Minnesota Twin Cities have developed a new 3D printing technique that creates lifelike human tissue structures. Their work could reshape surgical training by offering models that look, feel, and respond more like real human tissue.
The Minnesota team found a way to control the shape and size of microscopic patterns inside the printed material. Those patterns directly influence the strength and stretchiness of the tissues, giving them realistic mechanical properties. They also built a mathematical formula to predict how the tissues behave under stress.
