How a 3-D printer made a 3D model of a woman’s head to help diagnose breast cancer

A 3-d printer, which is currently being used to make 3D models of people’s heads, is making scientists use a different way of looking at the human body, and one that could eventually be used to diagnose breast cancers.The 3-dimensional printer uses laser-assisted design to print a 3,000-pixel mesh of human skin and muscle, then
