The University of South Wales Sydney 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 highly maneuverable swivel head that 'prints' the bioink, attached to the end of the arm, all of which can be controlled externally.

The research team said that with further development, and potentially within five to seven years, the technology could be used by medical professionals to access hard-to-reach areas inside the body via small skin incisions (vết rạch trên da) or natural orifices.
