Just as how the Industrial Revolution changed the face of the world, through unparalleled technological and economic progress alongside pollution, income disparity and other unforeseen outcomes. 3D Printing could also shape humanity if it fulfils its full potential but at what cost? No one will know for sure.
With the likely proliferation of 3D Printers in the future, the democratization of manufacturing will certainly change how our world functions and bring about the decentralization of business. The advent of this scenario could either bring about latency in humanity or an eruption of innovation owing to the actualization of ideas on an unprecedented level. Looking back at history, the latter would most likely occur since humanity has always built on past technologies to innovate and create new ones.
