The future of food?

The new world of 3D printing is on its way to revolutionizing personal weapons after the successful test of the first entirely 3D printed gun in early May, but mechanical engineer Anjan Contractor sees a different future for 3D printing: ending world hunger.

"One of the major advantages of a 3D printer is that it provides personalized nutrition," Contractor said. "If you're male, female, someone is sick — they all have different dietary needs. If you can program your needs into a 3D printer, it can print exactly the nutrients that person requires." Deseret News
