Over the past decade, 3D printing has shown great potential for medical applications. It has been used to manufacture hearing aids, surgical implants, and anatomic models, as well as biomaterials that mend or replace bone, skin, and blood vessels. Scientists hope that one day 3D printing could even help produce complete artificial organs.
Typically, 3D-printed tissues are created outside the body and then implanted surgically, a method that carries a risk of infection and other complications. It is also invasive, involving complex procedures and leaving large surgical incisions.
Recently, a team of scientists from the Terasaki Institute for Biomedical Innovation, Pennsylvania State Univ. (PSU), and Ohio State Univ. (OSU) developed a way to 3D print artificial tissue directly into the body. The technology shows promise for advancing the field of tissue engineering...
