This picture taken on January 21, 2015 shows intern doctors (R) attending a surgical lesson by Toshiaki Morikawa (not in picture), professor of Jikei University School of Medicine for using an artificial "Biotexture Wet Model" lung made by a 3D printer at the Jikei University hospital in Tokyo. An incision from the surgeon's scalpel sends liquid oozing over the surface of a the lung, but on this occasion it doesn't matter if something goes wrong -- the doctor can simply create another model with a 3D printer.
