5. The Founders
The first 3D printer, which used the
stereo lithography technique, was created
by Charles W. Hull in the mid1980s.
Stereo lithography is largely an expensive
commercial technique 1984s.
with machines often costing $100,000

6. History Of 3D Printing
 1984
Charles (Chuck) Hull developed the 1st 3D printer and
named the technique as Stereo Lithography.(SLA)
 Later 1990’s
Other companies developed 3d printers.
 2005
Z Crop launched first High definition color 3D printer.

7. Printing
Printing is the processes for reproducing text and images.
Device. used PRINTER
Types Of Printing.
 Dot Matrix
 Ink Jet
 Laser
 Lcd

8. What is 3D printing?
How Does 3D Printing work?

9. Introduction of 3D Printing
• 3D printing is a form of additive manufacturing technology where a three
dimensional object is created by laying down successive layers of material.
• It is also knows Additive Manufacturing.
• 3D Printing is archived using an additive processes, where successive layers of
material are laid down different shapes.

10. Working
 We only need a Printer, Raw Material, and Software ( CAD) to tell the printer
what to print.

11. Working Chart

12. 1st Step On CAD
A model of the object is created on a computer software analyses this model
taking a series of cross section and working out the distribution of space and solid
matter within each layer.

13. 2nd Step
CAD file is exported to a 3D printing Machine.

14. Layer By Layer
In layer system we are using material and create the any object with layer by
layer and create the final object.

15. Step 3 Actual Object
Once each layer in complete, the build tray is lowered by a fraction of a
millimeter and the construction of the next layer being. When all the layers have
been completed, any axcess material is cleaned away to reveal the finished
object.

17. Types of 3D Printing
There are some different types of 3d printers. There are (Four) types of these printers.

18. Current 3D Printing Technologies
Different methods.
 Selective laser sintering (SLS)
 Stereo lithography
 Fused deposition modeling (FDM)
 Laminated object manufacturing

19. SLS method
Selective laser sintering (SLS) is an additive manufacturing technique that uses a high
power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal
(direct metal laser sintering),ceramic or glass powders into a mass that has a desired 3-
dimensional shape).

20. 2nd TYPE STEREOLITHOGRAPHY
Stereo lithography is an additive manufacturing
process using a vat of liquid UV-curable
photopolymer ”resin” and a UV laser to build
parts a layer at a time.

21. STEREOLITHOGRAPHY WORKING

22. 3rd Fused deposition modeling (FDM)
Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for
modeling, prototyping, and production applications.

23. 4th Laminated object
manufacturing
LOM is a rapid prototyping system
developed by Helices Inc. In it, layers
of adhesive-coated paper, plastic
or metal laminates are successively
glued together and cut to shape with
a knife or laser cutter.

24. Application

25. Advantage & Disadvantage
Advantages.
 Customization. A major advantage in 3D printing. With just a raw material, a blueprint and 3D
printer one can print any design no matter how complex it might be.
 Increased productivity. Large amount of production rate.
 Affordability. The initial cost for setting up a 3d printing facility is definitely high, compared to
labor cost.
 Storage. In 3d printing there are no storage required because when needed thus excess product
are eliminated and no storage cost is required.
 Employment opportunities. Increase the demand of engineers who are needed to design and
built these printers.
 Health care. Customizable human body part and organ can now be manufactured.

26. Disadvantage.
 Decrease in manufacturing jobs. The greatly effect the economy of countries that rely
on a large number of low skill job.
 Limited size. With the help of 3d printer we are create a small size of object but in the
feature we are use in large items such as architectural.
 Limited Raw material. Traditional raw material are used in 3d printing. Presently we
are using 100 different types of raw material approximately.
 Production of Dangerous Items. With 3d printers, plastic guns, plastic knife, and any
other hazardous object can be created.

27. What will be in the future?
For many products the
standard conveyors can
be greatly reduced or completely
replace by 3D-printer, because the
end product - for example,
a car - will not be collected
from hundreds or thousands
of individual parts but will
be produced in one process

28. SUCCESS stories
 Auto parts: for example, parts of "Formula 1" car engines, are made by
direct laser sintering of metal;
 Aircraft parts: F-18 (fight aircraft) tube for the control system environment;
 Individual orthodontics: the company Align Technology uses the 3D Printing to
generate accurate individual dental braces for hundreds of thousands of patients
worldwide by stereo lithography from 3D-scans of the mouth; polymer is used as a
material for the production of staples;
 Individual hearing devices: manufactured by companies Siemens and Phonak, based
on 3D-scan of the ear canal, so that the device is ideally suited to the user;

29. SUCCESS stories
3D Printed Jaw

30. Conclusion
 Relatively New Technology.
 No restrictions on industry.
 Significant decrease in product development cycle and costs.
 Full effects on business and society still not know.
 Resistance to change.
