Researchers at ETH Zurich have 3D bioprinted elastic ear cartilage that retains its shape after implantation. Using cells from small surgical fragments, they grew millions of cells to create a custom ear implant that could replace current rib cartilage harvesting, which is painful and produces stiffer results. https://www.3dnatives.com/en/3d-bioprinting-of-elastic-ear-cartilage-20032026/ #3Dprint #3Dprinting #Medical #Biomedical
