Proponents hail 3-D printing as one of today’s most revolutionary technologies, even though mass adoption is still years away. Here’s how some firms are using the technology.
The Smithsonian Institution’s Digitization Program Office uses 3D scanning and printing technology to create replicas of artifacts that may be too fragile or precious to model in other ways. The printed versions can then be used for educational purposes, such as hands-on exhibits or in classrooms. The office has created plastic versions of President Abraham Lincoln’s life mask for the National Portrait Gallery and the National Museum of American History.Courtesy of the Smithsonian Institution
