2. Printing
Printing is a process for
reproducing text and
images, typically with
ink on paper using a
print press.

HISTORY OF PRINTING

4. Invention of first printing
machine
 FIRST PRINTING MACHINE WAS INVENTED BY JOHANNESGENSFLEISH IN 1803.
 THIS SUPERSEDED THE COST AND SLOW PRODUCTION.

5. HISTROY OF 3D Printing
3D printing was invented in the year 1984 by Charles Hull
with the advancements in printing methods after the
invention of inkjet printers in the year 1976.
Charles Hull is the co-founder, executive vice president and
chief technology officer of 3D systems.

7. Subtractive
Manufacturing
• Creates a product by removing sections from a block of material.
• Generates waste through the excess material that is removed.
• Limited design capabilities.

8. Computerized Numerical
Control (CNC) Machining
• A method of Subtractive Manufacturing
that removes sections from a block of
material by cutting or drilling the excess
material away.

9. 3D Printing
• A method of Additive Manufacturing that adds material to an object
layer by layer to create the final product.

10. Technique

11. A person creates a 3D image
of an item using a computer-
aided design (CAD) software
program.
The CAD information is sent
to the printer.
The printer forms the item
by depositing the material in
layers—starting from the
bottom layer—onto a
platform. In some cases light
or lasers are used to harden
the material.
How Does It Work ?

12. Different methods
Selective laser sintering (SLS)
Stereo lithography
Fused deposition modeling (FDM)
Laminated object manufacturing

13. 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

14. 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.

15. STEREOLITHOGRAPHY
(contd).
• CAD (Computer Assisted Design)
Programs help users create STL Files
for the 3D Printers to read.
• STL (STereoLithography) file format – a
file format which uses many little
triangles to make a 3 dimensional plot
of the objects intended surface.

16. FDM
Fused deposition
modeling (FDM) is an
additive manufacturing
technology commonly
used for modeling,
prototyping, and
production applications
The commonalty used
raw material is ABS-
M30 which is a kind of
plastic

17. Laminated object manufacturing
Laminated object
manufacturing (LOM) is
a rapid prototyping
system developed by
Helisys 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.

18. RAW MATERIAL USED FOR 3D PRINTING
 ABS-M30 :The ABS-M30 plastic formulation is the plastic
 ABS-ESD7 : ABS-ESD7 is the Stratasys electrostatic dissipative material
 PC-ABS
 ABS-M30i
 ABSi
 PC
 ULTEM 9085
 FDM Nylon 12
 ETC…

20. Functional Prototyping
Use:
Functional prototyping helps in
creating amazingly realistic
prototypes with the look and feel of a
real product.
Example:
Lamborghini, while developing its
new flagship model Aventador in
2011, made extensive use of 3D
printing technology to build a
functional prototype of the car.

21. Concept Modeling
Use:
Concept modeling lets small design
and engineering firms extend their
reach by testing out more ideas and
developing only the right projects. For
large companies, concept modeling
within departments — or even in
individual cubicles — is a way to hone
ideas before presenting them to
superiors.
Example:
California-based 3D Reprographics
makes architectural models for its
clients. They found 3D printing to be a
great fit for making a strong accurate
presentation model.

22. End Use Parts Use:
3D printing is capable of building
the most durable, stable, and
repeatable parts in the industry,
whose accuracy can be
compared with injection molding.
Example:
Kelly Manufacturing Company
(KMC), the world’s largest
manufacturer of general aviation
instruments, makes extensive use
of 3D printing by producing
prototypes of critical components
for an aircraft quickly; the process
would otherwise take an estimated
3-4 weeks.

23. Fashionable Plaster
This 3D-printed cast to help
repair broken bones may be the
future of medical orthopedic
casts. 3D-printed casts also bring
out the positive potential of this
emerging technology.

24. Fashion, Retail & Home decorator

25. Applications of 3D Printing
• Prototyping
• Modeling
• Custom parts
• Design
• Research

26. SUCCESS stories
3D printed Jaw
Artificial Arms for Disabled

27. Challenges Facing 3D
Printing
• Intellectual property rights of the
3D Printer users.
• Nearly anything can be printed
by 3D Printers and this is a
troubling prospect if criminals
use 3D Printers to create illegal
products.

28. In Conclusion
• 3D printing is an expanding technology
which may soon start an industry in which
everyone has the possibility of being a
manufacturer.
• 3D printing has a lot of possible benefits to
society, although the products created
must be regulated.
