The term project focuses on the present status of construction using 3D
concrete printing and how it can be improved, specifically the "concrete
mix" in order to achieve construction of big complex structures (i.e. high
rises, bridge decks) and the socioeconomic impact of this technology in the
society. 3D printing also known as additive manufacturing is a process of
producing a three-dimensional object/structure by laying down successive layers
of material until entirely completed. Each layer is a thing horizontal cross
section of the finished product. 3D printing technology has evolved over the
years to an extent that it is now capable of producing bigger
structures/objects of varying complexity. In 2014, A Chinese Company “Winsun
Decoration Design Engineering Co” printed 10 houses in 24 hours using a 3D
printer with a mixture of recycled construction waste and quick-drying cement.
In 2015, the same company demonstrated exceptional capabilities of the 3D
printing technology as they built the world’s tallest 3D printed building i.e.
a five-story apartment building. The building was created using a 6.6 by 10
meter printer which pours layers of a mixture composed of glass fiber, steel,
cement, hardening agents and recycled construction waste. Sections of the
building were printed in the plant and were assembled on site which is similar
to prefabricating concrete designs to create the final building. The building
met relevant national standards in terms of building code, it was declared
safe, reliable and features a good integration of architecture and decoration.
The rapid evolution and improvement of the 3D concrete printing has led
to numerous research on how this can be improved to build projects of even
bigger scale and complexity such as high rises, bridge decks, dams etc. The
main ingredient of this process is the concrete mix and thus it determines the
strength, size and complexity of the structure. Improvement in the concrete mix
leads improvement in the overall technology. Also, our research will comprise
if the possibility of 3D printing can be achieved using different construction
materials not only concrete hence increase the variety/options of construction.
The growth of this technology will have socioeconomic impact such as reduction
of housing costs hence improving standard of living (since 3D concrete printing
is cheaper than conventional construction method), impact on labor union can be
enormous since this process in general replaces labor work by the use of a
machine which pours layers of concrete.
The research will begin with a brief introduction of 3D concrete printing
technology, history and its evolution in the construction industry. Technical
aspects of the 3D concrete printing will be discussed such as the machine
pouring the concrete mix, the concrete mix itself and its properties as well
the as the assembly of the 3D printed construction elements i.e. walls, beams,
columns etc. The current application and the future of this industry will be analyzed
i.e. what scale and complexity of construction can be achieved as well as the
alternative materials which can be used instead of concrete. Furthermore,
socioeconomic impact of 3D concrete printing will be explored i.e. impact on
economy, labor union and improvement in living standards.

Maria - I agree with you
that robots such as SAM are used in the construction industry at present and it
is not only saving time but also reducing construction costs. With the
development of such machines, the future holds more prospects of extensive use
of robots in the construction industry which will be more powerful, efficient
and capable of doing complicated tasks. However, this can have major
socioeconomic impact on the society since it is replacing jobs of construction
workers hence creating a vacuum in the job market which in turn may have a
negative impact on the economy. Therefore it is important to factor in such
impacts due to advancement of technology and to find the balance so that the
impact is minimized.

Samuel - RTLS has a
wide range of scope, it is like a GPS device attached to every single person in
the building however in this case it holds more information than just the
location. It can be used in hotels where each guest is wearing a wearable that
provides information about his sleep patterns, choice of food/drinks, so that
the hotel personnel know when to wake him/her up or what type of food he/she
may like etc. This is an interesting idea, and its applications are immense, As
Derek mentioned in a big construction site where hundreds of workers are
working it can be used to locate a special technician when needed.
