Quoting the Smithsonian by way of an article posted to Yahoo, the word is:
Digital imaging specialists have created a 3D-printed bust and life mask of Obama, which will be his first presidential depictions in the National Portrait Gallery collection.
Anyone who has seen a 3D printer knows that the unit lays down a layer of plastic with each pass.
Considering his campaign claims, his scandals, and his record so far, it seems fitting since:
What you have said in the dark will be heard in the daylight, and what you have whispered in the ear in the inner rooms will be proclaimed from the roofs. (Luke 12:3 NIV)
