In the last decade, 3D printing has become an integral part
of many industries. One of those industries is the construction industry in which
companies are beginning utilize methods to print and build complete structures
using 3D printers. These companies are utilizing different techniques in order to
print structures, such as printing off-site and then shipping the printed parts
in sections to the site or bringing a large scale printer to the construction
site to print the structure in place. Both of these techniques are advantageous
over customary construction process. According to National Building
Specification (NBS) website, either of these options are advantageous over the
customary construction process[i].
Another advantage that the NBS states is that printers allow for faster and
more accurate construction, this means that errors rarely arise from
construction but instead from the digital model being incorrect or failure in
the material or equipment. Printed construction also reduces labor costs
because of a minimal amount of human effort required to complete the
construction. The NBS states another advantage to be reduced waste generated
during the construction process as each component is printed individually. A
final advantage that the NBS states is a reduced carbon footprint which is due
to less machinery being needed and depending on the type of material used less
carbon produced through the manufacturing of the material used[ii].
The adaptation
of 3D printing will change how buildings are constructed and the speed at which
they are constructed. According to the developer of Contour Crafting, Behrokh
Khoshnevis, our conventional construction practices are inefficient and outdated[iii].
He also claims that they are slow, labor intensive, and very dangerous thus by
switching to 3D printed buildings, the construction process will progress at a
much quicker pace, require less laborers, and eliminate some danger on
construction sites[iv]. These
methods alleviate the problems by first having all the pieces either fabricated
on site by a printer or fabricated offsite and then shipped at once to increase
the speed the building is erected. Offsite fabrication will speed up the
process because the components can be printed ahead of schedule or in a factory
by multiple printers. Printed buildings require fewer laborers to build the
structure because the printed pieces would need to be assembled as compared to
customary construction in which studs are erected, sheathed, and finally
finishes are added. The printed buildings already have their finished textures
printed onto them which eliminates the time it takes to add these finishes in
customary construction methods.
This
thesis seeks to define a series of building components when assembled become a
house. A building is made up of many different components that when each are
put together become a building. By taking each of these components and looking
at how they are put together a new method of construction can arise out of the
new technology at hand. Printers can build these pieces to allow for the
components to fit together and become a shelter.
