Customer Andreas Kroker looks at a 3D-printed figure of himself at the Twinkind 3D printing studio in Berlin, December 13, 2013. A 3D-printed likeness is produced by taking a 360 degree photographic scan of a person, which is then rendered into a 3D digital model and retouched to meet the requirements for printing. The printing machine uses this digital model to produce a high-resolution solid figure. Twinkind co-founder Timo Schaedel said, people often come to the session well-groomed, with fresh hair-cuts and their best clothes, “just as they used to do in the past, when they had their portrait taken in a photo studio”.
