Old 3D print of Hagia Sophia emerges

In the 1990s Professor Ely Sachs of the Massachusetts Institute of Technology (MIT) was the first person to coin the phrase “3D printing.” Utilizing a printer, which worked with alumina powder and a binding agent, several prints were created in surprising detail for the mid-1990s. Most of these prints were lost, but one has recently emerged, a 3D print of the Hagia Sophia.
