3-D printing is driving a huge revolution in the world of design and technology. In the process, it is changing the way we think about the design, prototyping, and manufacturing of just about everything.
But anyone who has played with a 3-D printer will be aware of one significant problem. This 800-pound gorilla is the issue of color. 3-D prints can be magnificent copies of more or less any shape. But in terms of color, they are mere shadows of the originals.
Today, that looks set to change thanks to the work of Alan Brunton and pals at the Fraunhofer Institute for Computer Graphics Research in Germany, who have worked out how to produce accurate colors in a 3-D print for the first time. Their work promises to take 3-D printing to an entirely new level.
