Digital part materialization, otherwise known as 3D printing, is one of the most exciting new technologies to emerge in the new millennium. The benefits of the digital process go far beyond minimizing waste and saving time. However, as a mass production technique, it is still in its infancy. One of the companies pioneering this revolutionary process is ExOne GmbH in Gersthofen, Germany. Having gone well beyond the prototyping stage, this technology is now ready to come of age.
