Minnesota engineers create realistic 3D-printed human tissue for surgical training

Minnesota engineers have developed 3D-printed human tissue that mimics the feel and stretch of real organs, improving surgical training models. The new technique controls microscopic patterns to create realistic mechanical properties and includes blood-like liquids sealed within microcapsules for enhanced realism. Surgeons rated these models higher for tactile feedback and cutting response compared to conventional replicas. This advancement could lead to more effective surgical preparation, potentially improving patient outcomes. Future research aims to replicate diverse organ shapes and functions, and explore bionic organ development.
