Engineers have developed a flexible robot that enters the rectum to 3D print living cells on damaged organs, eliminating the need for patients to 'go under the knife.'
The University of South Wales team designed the miniature robotic arm to directly deliver 'bioink,' made of gelatin, collagen, human cells and other materials, onto the surface of internal organs and tissues.
The proof-of-concept device, known as F3DB, features a head that 'prints' the bioink, attached to the end of the arm, all of which can be controlled externally.
