3D printing is a process that builds 3D objects layer by layer from a digital model. This process, known as contour crafting, can now print entire buildings using concrete in a similar way that 2D printers use ink. Contour crafting allows for the insertion of structural components, plumbing, wiring, and devices during the printing process. With 3D printers, buildings can now be constructed quickly from a digital design file without the need for construction labor. This new construction technique is faster, more accurate, and more sustainable than traditional methods.

3.  3D printing is a manufacturing process that builds
layers to create a 3D solid object from a digital
model.

4.  The process of printing
buildings and their
components by 3D printer
is known as contour
crafting
 It uses quick setting
concrete as a basic
construction material in
the same way as ink is
used by 2D printers

5.  Insertion of every
Structural component
plumbing, wiring and
even consumer devices
audiovisual systems is
made possible in contour
crafting
 With the invent of 3D
printers your building
is only a print command
away from you

6.  Technology of printing 3d objects from digital data was
first of all developed by Charles Hull in 1984 and was
named as stereo-lithography.
 In 1993 MIT presented another technology and named it
3D printing technique.
 In 2001 rep rap project was initiated which can print
2000 prototypes in a day from any material.
 But the actual breakthrough occurred in the year 2006
with the advent of the technology known as contour
crafting which is uniquely applicable to the
construction of large building by 3D printing.

10. There are no chances of error in 3D printed construction
.
It does not employ any labour for construction or during
construction phase.
Nothing goes waste in 3D printing construction as those raw
materials that are not used are retained by printer and
recycled.

11. It replaces the dangerous jobs on site with printing process.
It bridges gap through rapid prototype technique.
It is incredibly faster than the conventional methods hence
saves our time.
Last but not the least it is eco-friendly, as it uses recycled
materials.

12. 3D printing is not only
limited to the rapid
prototyping but a company
in china has designed a
gigantic 3D printer of the
size 32*10*6.6 meter that
can print 200 square feet
detached single story room
which costs less than $5000
and the printer can print at
the phenomenal rate of 10
buildings per day

13.  3D printers at present have created a truss support system within the
cement beams, saving weight and increasing strength at the same
time, as well the good replacement to concrete

17. NASA is planning to construct the extra terrestrial
Structures by 3D printing technology on Moon and Mars for
astronauts to stay that too by entirely commanding the printer from
earth itself.

18.  After canal house Amsterdam is going is print the
bridge from 3D printer by converting the design of
printer from a box to the robotic arms

19.  By 3D Printing, Construction of luxury structures with
exotic architectural designs involving complex curves and
other geometries is made possible.
 There are numerous research tasks that need to be
undertaken to bring the 3D printing construction technology
to commercial use.
 We hope one day we will print the entire cities, including
roads by 3D Printer.
