This document discusses 3D printing technology used to construct large buildings. It describes a massive 3D printer with a build volume of 12m x 12m x 12m that was used to print full scale houses and other structures in China. The 3D printer extrudes a mixture of cement and recycled materials layer by layer to build according to CAD designs. This technology allows construction to be done faster, cheaper, and more sustainably by reducing waste and using recycled materials. It has potential applications to provide affordable housing and construct large buildings like skyscrapers.

2. INTRODUCTION:-
3D printing or additive manufacturing is a
computer-controlled production technique
that builds a product layer by layer.
It is called additive manufacturing because a
new material is continually added to it when
it wants

3. DIMENSIONS:-
This massive 3D printer has
a build volume of 12 m x 12
m x 12 m. According to Wang
Hong, company's founder
and CEO, the company has
spent the last 6 months
developing this giant printer.
It weighs more than 120 tons
and was assembled using
cranes and other machines.

4. DESIGN COMMAND:-
Using CAD software for
the architectural plan,
calculated tracing paths
consider insulation
materials, plumbing,
electrical lining &
windows, which can later
be out fitted once the rest
of the structure is
assembled.

5. ASSEMBLING PROCESS:-

6. FUTURE DEVOLPMENTS:-
The Chinese company Win Sun
has built houses using large 3D
printers sparing a mixture of quick
drying cement and recycled raw
materials. This technology can be
used to build cost effective,
environmentally sustainable
affordable housing. Large
buildings, including skyscrapers,
are expected to be built using this
technology.

12. Print stock from pollution

13. Curve appeal

14. ADVANTAGES:-
Recycle concrete, building waste &
industrial wastages are used in
stood of using bricks & motor.
Cheap in construction when
compared to reinforced cement
concrete.
By using waste materials like
concrete waste etc are recycled.

15. ADVANTAGES:-
The system extrudes a mix of
high grade cement & glass
fabric material, layer by layer,
similar to traditional rapid
prototyping process gives more
strength to this concrete.
Less labor is required in this
construction works.

16. ADVANTAGES:-
Durability of this concrete is very
high.
It is easy to construct a colony
within a short period of time.
This printed is easy to carry by
folding it.
It can fit windows, electrical lines
& plumbing works etc.

17. DISADVANTAGES
Reduced employee numbers in the industry, since the 3D
printer does most of the work
A limited number of materials can be used, since the same
printer might not be able to print the required multiple materials
Higher risks – any errors in the digital model can result in
problematic issues on site during the printing/construction
phase
Conventional product manufacturing companies and plant
renting companies could suffer as their products are no longer
required

18. CONCLUSION:-
By using this technology the
structures will constructed
quickly, cheaply, economically,
recycles, reduction of waste
materials & eco friendly .The
technology used to build
colonies for people who are
economically poor with low
capital. This technology will
create a resolution in future in
civil engineering projects.
