New 3D printing techniques are providing a way for an RIT researcher to create platforms to help regenerate human tissue that allows the body to heal itself more effectively. This work could reduce the need for human organ donations in the future. Iris Rivero, an engineering professor at Rochester Institute of Technology, has found that compatible combinations of polymers and biomaterials can be successfully used to fabricate “scaffolds,” 3D-printed structures that signal the body to begin its ...
