This document discusses 3D printing technology in construction. It provides an overview of 3D printing and how the process works to build objects layer by layer. The history and first uses of 3D printing in construction are described, including building the first 3D printed house in France in 24 hours. Comparisons are made between 3D printing and traditional construction methods, noting advantages of 3D printing like lower costs, waste, and time. Potential future benefits are outlined, such as new design possibilities, precision, and remote construction. Examples of a 3D printed bridge and canal are provided. Disadvantages and challenges are also acknowledged.

 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

9. General principles
 Modeling.
 Printing.
 Finishing.

10. 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.

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

12. 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.

14. COMPARISON BETWEEN 3D
PRINTING AND
OTHER CONSTRUCTION
TECHNOLOGIES

15. 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.

16. 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.

17. 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.

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

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

20. 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.

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

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

23. PRINTING OF 3D BRIDGE
AND CANAL

24. 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.

26. 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.

28. 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.

29.  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.

30. 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.
