Organ Printing Bioprinting is a relatively new field that involves creating living tissue with a three dimensional printer. The process of 3D printing is becoming increasingly popular in many fields as it allows for the direct digital manufacture of a wide variety of plastic and metal items. While this technology is revolutionizing by itself‚ it is now being applied to the field of tissue engineering to produce biological tissue in the form of bioprinters. These devices artificially construct living
