How 3-D printing is changing healthcare

Some research institutions, including the Mayo Clinic, have set up on-site printing labs in partnership with such makers of 3-D printers as Stratasys , 3D Systems and Formlabs. General Electric Co. and Johnson & Johnson are diving in, too, with GE focused on 3-D printers and translating images from various sources into 3-D objects, and J&J focused on developing a range of materials that can be used as “ink” to print customized objects.
