Commonly used to support or replace body parts that don’t enter the bloodstream, 3-D printing has the ability to fabricate prosthetic limbs, layer by layer, from the ground up. What is 3-D printing? What is 3-D printing? In medicine, 3-D printing, also referred as additive manufacturing, is the process of using plastic or metal gel to shape a replacement body part based on a patient’s MRI or CT scan. 3-D printing is allowing prosthetics to be produced and personalized in complex shapes including hands and fingers. No longer will these devices cost thousands of dollars, removing much of the financial burden patients and their families may face. “If a parent wanted to purchase a 3-D printer of their own and produce hands for their own child, the cost of the printer and
