Since 3D printing is already a reality, I decided to do a bit of predicting on my own. At present, 3D printers use feedstock which must be purchased separately and brought to the printer. In the future, liquid feedstock will be delivered to users by two pipes, one containing corn or soybean derivatives as base material for food and the other pipe containing a base material for making objects. It may still be necessary to purchase printer cartridges to supply trace elements, not ink, that are needed.

When 3D printers are commonplace, only the wealthy will be able to afford real, organic food. The rest of us will manufacture our food cheaply at home.
