Housing and shelter remains the most important of human
needs, and a majority of the urban population in developing countries is in
desperate need for this very fundamental of human needs. Despite this we do not
see significant advancement in technologies that address this critical issue.
Recently, a friend shared this video about this new technology that could be
the beginning of an answer.
3D printing is fast gaining popularity in the field of
product prototyping. Now, we can print an entire 2,500 sqft house in 20
hours. In manufacturing we use a process called CAD/CAM (computer-aided
design / computer-aided manufacturing). 3D models are designed on a computer
and then manufactured using CNC Machines or 3D printers. The design is
manufactured into a physical object automatically, with instruction from 3D
computer model to physical object without human interface. Automated
construction basically scales up this process. The size of the 3D printer is
large enough to construct walls by depositing concrete based material layer
upon layer to build a wall.
We all know that the way towards affordability is:
1. Modularity
2. Standardization
3. Mass production
In the past, these have given rise to the post WW-II housing
in Europe and tract housing in the US. The reason behind this was that the
available technology produced similar-looking, homogeneous places. But
this technology has the potential to address that, allowing us to produce
unique houses, as was demonstrated using Nader Khalili's vaulted mud houses.
By integrating BIM/ BAM with CAD/ CAM will take
Computational/ Parametric Design to a whole new level. This is a new frontier
for architectural design and impact potential on urban environments.
In the TED Talk video below, Behrokh Khoshnevis, a professor of Industrial & Systems Engineering at the University of Southern California (USC), demonstrates automated construction, using 3D printers to build an entire house in 20 hours.
