The tiny, flexible device has the ability to enter the body like an endoscope and print multilayered biomaterials directly onto the surface of internal organs and tissues. They predict that within 5 to 7 years they'll be able to acess hard-to-reach areas inside the body through small skin incisions or natural orifices.
"Existing 3D bioprinting techniques require biomaterials to be made outside the body and implanting that into a person would usually require large open-field open surgery which increases infection risks"

This system offers the potential for the precise reconstruction of three-dimensional wounds inside the body, such as gastric wall injuries or damage and disease inside the colon"
