A miniature 3D bio printing robot has been developed.
The 30mm long robot when introduced into the body, unfolds & starts bio printing.
It was fitted onto an endoscope which was snaked through a curved pipe into a stomach model.
The device then printed gels packed with lab grown human stomach lining and muscle cells.
These cells remained viable over the course of 10 days.
The technology will be useful to repair wounds and to augment existing surgical procedures.
Later it can be used to bioprint living organs that can be used for transplant.
