3D printing - 3D printing is gaining traction in Africa. In 2013, WoeLabs tech hub in Togo made the first "Made in Africa" 3D printer from e-waste. They want to use the 3D printer to revolutionize Africa. They're starting by putting a machine in every school within 1km of the workshop. Buni Hub is another tech center, based in Tanzania, that is building 3D printers.
