LOME, TOGO  13-05-31   -  Kodjo Afate Gnikou and his $100 US 3D printer W.AFATE, which is largely made of e-waste, in Lome, Togo on May 31, 2013. Gnikou dreams of sending a larger version to Mars to print tools and homes for future colonizations. &quot;They all say it is merely a dream and it will never happen,&quot; says Gnikou, pointing out that there are already robots on Mars. &quot;I really want my 3D printer to be the first on Mars so people can say it was an African who had the idea to put a 3D printer on Mars.&quot;  Photo by Daniel Hayduk
