Sydney: Researchers have taken 3D printing a step further by creating a soft printer that can print cells directly onto human organs. University of New South Wales (UNSW) experts’ robot can print cells on human tissues and organs inside the body. Although bioprinting robots that print heart tissue, biological components, and gastrointestinal grafts have been in the works for a long time, there has been little success until now. It is a small and flexible robotic arm that can be inserted into the body like an endoscope. The robotic system injects the biomaterial directly into tissues and organs. However, it has not been tested yet, instead experts have made a model that enables this process, which can be called a proof of concept.
