Lifelike 3D-printed organ models developed to enhance surgical outcomes

Realistic artificial organ models that mimic the anatomical structure, mechanical properties and feel of real organs have been developed using 3D printing methods.

A team from the University of Minnesota used MRI scans and tissue samples from real organs to develop customised silicone-based inks that can be tailored to precisely match the mechanical properties of each patient's tissue.

Soft 3D-printed sensors were then attached to the organ models to measure their reactions during compression tests and the application of various surgical tools, giving surgeons real-time feedback on how much force they can apply without causing damage.

This makes them ideal for use in practice surgeries, meaning they can help to improve surgical outcomes worldwide.

Lead researcher Michael McAlpine, an associate professor of mechanical engineering in the University of Minnesota's college of science and engineering, said: "We think these organ models could be game-changers for helping surgeons better plan and practice for surgery. We hope this will save lives by reducing medical errors during surgery."
