The first presidential portraits created from 3-D scan data are now on display in the Smithsonian Castle. The portraits of President Barack Obama were created based on data collected by a Smithsonian-led team of 3-D digital imaging specialists and include a digital and 3-D printed bust and life mask. A video released by the White House details the behind-the-scenes process of scanning, creating and printing the historic portraits and can be seen below. The portraits have been on view in the Commons gallery since Dec. 2nd and were previously displayed at the White House Maker Faire June 18.
The Smithsonian-led team scanned the President earlier this year using two distinct 3-D documentation processes. Experts from the University of Southern California’s Institute for Creative Technologies used their Light Stage face scanner to document the President’s face from ear to ear in high resolution. Next, a Smithsonian team used handheld 3-D scanners and traditional single-lens reflex cameras to record peripheral 3-D data to create an accurate bust.
The data captured was post-processed by 3-D graphics experts at the software company Autodesk to create final high-resolution models. The life mask and bust were then printed using 3D Systems’ Selective Laser Sintering
The data and the printed models are part of the collection of the Smithsonian’s National Portrait Gallery. The Portrait Gallery’s collection has multiple images of every U.S. president, and these portraits will support the current and future collection of works the museum has to represent Obama.
The life-mask scan of Obama joins only three other presidential life masks in the Portrait Gallery’s collection: one of George Washington created by Jean-Antoine Houdon and two of Abraham Lincoln created by Leonard Wells Volk (1860) and Clark Mills (1865). The Washington and Lincoln life masks were created using traditional plaster-casting methods. The Lincoln life masks are currently available to explore and download on the Smithsonian’s X 3D website.
