3D printers capable of making 3D replicas of any 3D design have come to transform our lives. Allowing from small toys to homes of different designs.
From the typical houses of the Eskimos: The igloos, to tipis (typical shops of the American Indians), pasiegas cabins (typical of Cantabria) malocas (typical Amazonian Indians), houses on land (Constructions buried in Nordic countries), etc.
The houses of the world evolve in houses in 3D.
The houses in 3D in principle seemed that they were going to be basic houses to improve the life of people who lived in shacks in areas of few resources or as houses built to replace the usual ones when natural catastrophes are lost. Now it is planned to build 3D houses in residential areas as in Eindhoven, the Netherlands.

Another way of using the 3D printer will be in the construction of parts such as certain windows or structures. As well as to make the small pieces that we need at the moment either for technological devices or machinery of any kind.
The future real estate is reaching new limits unimaginable just a century ago and only time can tell us how far.
In another field different but not less useful prostheses that are already starting to be exported to African countries will be another way to improve the lives of many people and one of the best utilities of these printers so far.

Although the great revolution can be in the food world when you can clone a food in 3d printers. Not being necessary therefore the annihilation and death of so many animals in a world with more and more overpopulation and less resources.
