I recently held a 3D printed exhibition at Heathrow Terminal 5 (summer 2016)- the exhibition was sponsored by AutoDesk, Nikon, Ultimaker, 3d Filaprint and MyMiniFactory and was seen by an estimated 5 million passengers. I have just launched a kickstarter project that explores the potential of 3d printing and casting from photogrammetry and be great to get feedback on this- if you like it please pass it on!
