Ever heard of Nikita Chen-yun-tai? Apparently, he invented a mobile 3D printer called Apis Cor that is capable of printing buildings (http://www.forconstructionpros.com/news/12125977/russian-engineer-creates-mobile-3d-printer-for-construction). A construction company named Apis Cor has won a $45K grant. Is there a connection with Chen-yun-tai, Winsun Energy Co. Ltd. or Behrokh Khoshnevis and contour crafting?
