Looking for a New House – Don’t Build It, Print It

The title of this post may be a bit of an exaggeration, but technological advances now make it possible to build your own house if you have a mobile construction 3D printer that is capable of printing whole buildings completely on-site.  Based on recent experiences in the actually construction of such homes, the estimated total cost could be $10,134, or $25 per square foot, when using the highest quality materials.  The cost includes the foundation, roof, interior and exterior walls, wall insulation, windows, floors and suspended ceiling.   The company Apis Cor continues to develop the techniques and improve upon the cost per square foot; its product could have enormous benefits for providing affordable housing and allowing for faster recovery after natural disasters.

The term “3D printing” gives way to “additive manufacturing” for industrial use.  It differs from standard manufacturing processes of starting with your raw materials and then removing from them in the form of cutting, drilling, machining, and so on – all of which leave you with material waste.  Additive manufacturing means that you start with nothing and  only add what you need.  This is true in the construction industry as well.  It seems like both a financially responsible and environmentally friendly goal to have a process that would help to eliminate additional resources and the potential for a pile of construction waste at the end of the project.  The technology also allows for different methods of printing walls to achieve the desired thermal insulation.

These hi-tech homes could be very convenient “spaces” to house unexpected overnight guests and relatives.  I would not recommend, however, that in-laws be included in this category.)
