New 3D Printing Method Creates Photo-Real Objects

Most 3D-printed objects currently come in a variety of exciting monochromatic colors. You've got red, white, blue and, if you're really lucky, a mix of two colors. And while the objects may have a great deal of detail, the surface will be bland. Now, researchers have found a way to precisely affix complex coloring to objects, making them look somewhat photo-real (and perhaps a bit creepy). The method, developed by a pair of teams at Zhejiang University and Columbia University, is called computational hydrographic printing.
