3. What is 3D Printing
 The action or process of making a physical object
from a three dimensional digital model typically
by laying down many thin layers of material in
succession.
 3D printers are a new generation of machines that
can make everyday things. They’re remarkable
because they can produce different kinds of
objects.

4. History of 3D Printing
 The first 3D printing attempts are granted by Dr.
Kodama for his development of a rapid
prototyping technique in 1980. He was the first to
describe a layer by layer approach for
manufacturing creating an ancestor for SLA

5. History of 3D Printing
 In the same time Charles Hull was also interested in
the technology and deposited a first patent for
stereolithography in 1986. He founded the 3D system
corporation and a year later the SLA-1 released.
 In 2009 the 3D printing became such a hot topic that
it was easy to believe it was a brand new innovation for
creating an object.

6. 3D Printing Capabilities
 3D printing allows artist to create objects that would
be incredibly difficult costly or time intensive using
traditional processes.
 3D saves time and cost creating complete models in a
single process using 3D printing has great benefits this
innovative technology has been proven to save
companies time man power and money.

7. 3D Printing Capabilities
 Product Formation is currently the main use of 3D
printing technology.
 In medical field surgeons are using 3D printing
machines to print body parts for reference before
complex surgeries.
 Architects need to create mockups of their design 3D
printing allows them to come up with these mockups
in short period of time.

8. How 3D Printing Works
 Before printing a 3D model from an STL file, it must
first be examine for errors. Most CAD applications
produce errors in output STL files of the following
types.
 Holes
 Faces normal
 Self-intersection
 Noise shells
 Manifold Errors

9. How 3D Printing Works
 You start by designing a 3D object on an ordinary
home PC, connect it to a 3D printer press print and
then sit back and watch. The process is a bit like
making a loaf of sliced of bread.
 3D printing turns a whole object into thousand of
tiny little slices, then makes it from the bottom-up
slice by slice, those tiny layers stick together to
form a solid object.

10. Application of 3D Printing
Manufacturing Applications
Medical Applications
Industrial Applications
Sociocultural Applications

11. Application of 3D Printing
 Manufacturing Applications- A three dimensional
printing makes it as cheap to create a single items as it
is to produce thousand and thus undermines
economies of scale.
 Medical Applications- Surgical uses a 3D printing-
centric therapies by practicing on a tactile model
before surgery surgeons are more prepared and
patients received better care. Patients matched
implants were a natural extention of this work.

12. Application of 3D printing
 Industrial Applications- 3D printing is used to
manufacture moulds for making jewelry and even the
jewelry itself. 3D printing is becoming more popular in
the customisable gifts industry with products such as
personalized models of art and dolls.
 Sociocultural Applcations- Home use market was
established with inaguration of open source project
Virtually all home used 3D printers.
