3D printed ear mimics real human ear texture and feel

Researchers in Switzerland have achieved a significant milestone by 3D printing a highly realistic human ear using cartilage cells from patients. This advancement, which follows decades of efforts to create functional ear tissue, has produced elastic cartilage that mimics the mechanical properties of natural ears. The development could transform reconstruction methods for individuals who have lost an ear due to injury or congenital conditions, moving away from painful rib cartilage harvesting.
