This new process essentially bio-fabricates usable conglomerations of human stem cells by printing bio-ink, made up of a number of organic components including HEK293 (human embryonic kidney) via a valve-based printer with very fine nanoliter capacity (an ounce of liquid contains 29,573,529 nanoliters). The nozzle of the valve-based printer that they used is only .002 inches wide.
