The Smithsonian Institute has 3D scanned President Obama, and then printed out a life sized bust which will make it's way into the National Portrait Gallery along with other presidents. Obama, will stand out however, in that his bust is the first and only Presidential bust which has been 3D printed. The 3D print was unveiled at the White House Makers Faire earlier today, and attendees were pretty interested in the piece. Many of them took self photos of themselves standing next to the Obama 3D print.
