Click to enlarge The top images show the digital design and its printed form. Purple corresponds to ultraviolet cured stiff epoxide regions, whereas the gray regions are visible light cured acrylate regions that are soft and compliant. At the bottom, the logo for the 3D printing group, MASC, is turned into a printed object composed of both stiff, opaque regions and soft, transparent regions. 3D printing has revolutionized the fields of healthcare, biomedical engineering, manufacturing and art design. Successful applications have come despite the fact that most 3D printing techniques can only produce parts made of one material at a time. More complex applications could be developed if 3D printers could use different materials and create multi-material parts. New research uses different wavelengths of light to achieve this complexity. Scientists at the University of Wisconsin-Madison developed a novel 3D printer that uses patterns of visible and ultraviolet light to […]
