 3D printing
 3D printing in construction
 3D printing technology process
 History of 3D printing technology
 Comparison with other technologies
 Future benefits
 Disadvantages of 3D printing technology
 3D moon building.

5.
3D Printing
Computer controlled sequential
layering of material.
To create three-dimensional
(3D) shapes.

6.
Construction 3D Printing
 3DCP refers to various technologies
that use 3D Printing as a core method
to fabricate building or construction
components.
 It is also known as:
Rapid prototyping
Additive manufacturing.

7.
Process of
3D printing
Construction

8.
General principles
 Modeling.
 Printing.
 Finishing.

9.
Process of 3D building construction:
1.A person creates a 3D image of an item
using a CAD software program.
2.The CAD information is sent to the printer.
3.The printer forms the item by depositing
the material in layers-starting from bottom
layer .In some cases light or lasers are used
to harden the material.

10.
History
 The technology for printing
physical 3D object from digital
data was first developed by Chuck
Hull in 1984.
 The father of 3D printing.

11.
First 3D House In World
 In French.
 Overall the 95 metre.
 Within 54 hours.
 The building cost is 20% cheaper than an
identical construction with traditional
methods.
 Good thermal resistance, air circulation.

12.
COMPARISON BETWEEN 3D
PRINTING AND
OTHER CONSTRUCTION
TECHNOLOGIES

13.
ENVIRONMENT
3D printing
 major environmentally
friendly.
 waste reduction.
 plastics,resin,certain
metals,ceramics are used.
 no environmental impact.
 no pollution.
 no waste.
other technologies
 more waste production.
 plastics, ceramics are not used
in some construction
technologies.
 Environmental impact.
 co2 is emitted.
 pollution.

14.
COST
3D printing
 low material cost.
 low labor cost.
 the printer does most
of the work.
 great for business’
bottom line.
Other technologies
 large material cost.
 high labor cost.
 take large time.
 the labors do most of
the work.

15.
TIME CONSUMPTION
3D printer
 low time
consumption.
 One day is enough.
 within 42 hours, 3D
printer build a big
house.
other technologies
 high time
consumption.
 Minimum 6 mouths are
required.
 high cost.

16.
THE FUTURE
BENEFITS
FOR 3D PRINTING IN
THE CONSTRUCTION

17.
NEW SHAPES AND DESIGN
POSSIBILITIES
 flexible in the shapes of the designs.
 build curvilinear and rectilinear structure easily
 strongest structural.
 any shapes and size.

18.
LOW COST
 low cost on both a large structure scale
and regard to parts.
 have potential for far lower material costs
and labor.
 very helpful for poor people.
 in China , they can be produced for less than
$5,000.

19.
REMOTE LOCATION
CONSTRUCTION
 out of this world use of 3D
printing.
 moon building.
 3D printing could take us
anywhere.

20.
MORE PRECISE
BUILDING
 better and more precise results.
 on small amount of area, 3D printer
build more precise building.

21.
PRINTING OF 3D BRIDGE
AND CANAL

22.
BUILDING THE WORLD’S FIRST
PEDESTRIAN 3D BRIDGE
 on 26th December 2016.
 in Madrid, Spain.
 12 meters in length.
 1.75 meters wide.
 Build by waste material.

23.
BUILDING A CANAL
 In Amsterdam.
 In 2014.
 The printer used 3D plastic to construct the
canal.
 WAAM 3D printing is used.
 Build by waste material with other material.

24.
DISADVANTAGES
 automated fabrication is not suitable for large scale
products and conventional design approaches.
 Smaller ratio of automated products in comparison with
other industries.
 only limited material can be used by automated
machines.
 Reduced employee numbers in the industry, as the 3D
printer does most of the work.

25.
 transportation of the printer to the site and safe storage
of it on site is problematic.
 any error in the digital model can result in problematic
issues on site during the printing or construction phase ,
that may require special handing .
 manufacture of conventional building products and plant
renting companies could suffer as their products demand
may decrease.

26.
3D PRINTED MOON
BUILDING
 The building have to build on moon from material already on its
surface.
 The printers , operated by robots, would use soil from the moon.
 Site-the southern pole of the moon.
 Silicon, aluminium, calcium, iron, magnesium oxide could be used by
3D printer.
 first we plan the building plan with the help of CADD software.
 It send to 3D printer to moon with robots.
 3D printer build the building on moon with moonsoil.
 Hopes to be ready to start production by 2020.
