Robot prototype 3D prints biomaterials inside human body, lowering surgical risks

Biomedical engineers in Australia have developed a prototype of a small flexible robot that they say can be used to 3D print biomaterials directly inside the human body. The device called F3DB functions like an endoscopic tool, and may have applications as a way to repair ruptured tissue or blood vessels without the need for more invasive surgeries. The alternative treatment could in turn low risks associated with surgery, including blood loss and infections.
