See, NASA is now funding a project in the fast-growing field of 3D printers.
These are devices that take blueprints and turn them into real objects. The "printer" has a nozzle that spits out special polymers. Once you add a binding agent, you can create everything from replica car parts to human jaws.
Now, with funding from NASA, USC engineering professor Behrokh Khoshnevis has devised a process he calls "contour crafting." The prof says the printed home of the future will have it all - wiring, plumbing, and air conditioning. He says this field has the "potential to build safe, reliable, and affordable lunar and Martian structures, habitats, laboratories, and other facilities before the arrival of human beings."
