I was watching Al Jazeera and this group of people were talking about how 3-D printing was not going to be the wave of the future but rather the actual raw materials that make up a component or consumer device. They likened it to amino acids in a DNA chain.
In other words I buy a turntable,,,,when I do not need it anymore I take it somewhere were the basic raw materials are exchanged back for a different item or for future production. They called it circular production; more complex than recycling. I could not really understand it that well.
