Describes about the basics of 3d printing

1. 3D printing
ENDLESS OPPERTUNITIES

2. Title
• “3D printing” or “Additive Manufacturing”
takes digital input in the form of Computer
Aided Design (CAD) model and creates
solid, three dimensional parts through an
additive, layer by layer process.

3. How does it work
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.

1999
First application of 3D printing in the medical field
- creating the human bladder

6. 2000
Miniature human kidney created through 3D
printing

The Selective Laser Sintering machine – printing
multiple materials & fields
2009
First usable prosthetic leg – this opens the door
for customized products using 3D printing
2011
3D printers start offering 14k gold as printable
material

7. Projected growth
It is predicted that the 3D printing industry is set to grow 300% in the next 7
years!

9. 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.

10. unctional 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.

11. Manufacturing tools
Use:
Quick, low-volume tooling and
custom fixtures give
manufacturers the flexibility to
embrace more opportunities.
Example:
Xerox introduced a low-volume
printer to serve a specialized
market. 3D printing offered quick
solutions with 350 components
printed and generated within 1
hour for testing of the new
machine.

12. d 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.

13. Finishing Use:
Sealing, polishing and painting
expand the possibilities of
what a 3D printer is capable of.
Example:
Product Development
Solutions (PDS) specializes in
supplying components to a
wide range of industries
including medical and
aerospace. It makes extensive
use of 3D printing technology
in finishing and painting the
parts for a better look and feel
of components.

15. 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.

16. icial Arms for Disabled
Richard Van As, a South African
carpenter, assembles a Robohand and
fits it to Liam Dippenaar. Liam was
born without fingers on his right hand.
Makerbot provided them with the 3D
printing technology that they used to
print the parts for the Robohand.

17. Bionic Ears
Scientists, including an Indian-origin
researcher, have created a 3D-printed
bionic ear that can "hear" radio
frequencies far beyond the range of
normal human capability. Using off-
the-shelf printing tools, the scientists
at Princeton University explored 3D
printing of cells and nano particles,
creating the bionic ear.

18. Secrets of the Heart
Laura Olivieri, a pediatric cardiologist
at the Children's National Medical
Center in Washington DC (which spent
$250,000 on the 3D printer) says that
these replica hearts are ideal for dry
runs of complex operations, allowing
the surgeon to see beforehand the
exact anatomical landscape they will
have to navigate.

19. ow Your Own Organs
Surgeon Dr. Anthony Atala
demonstrated during TED an early-
stage experiment that could someday
solve the organ-donor problem: a 3D
printer that uses living cells to print out
a transplantable kidney.

20. st Toying
Crayon Creatures is a service to turn
children’s drawings into figurines—
nice-looking designer objects to
decorate the home and office with a
colorful touch of wild creativity.

21. mated Characters
Sony pictures was the first to embrace
the concept of 3D printing to create
characters for the movie Pirates – A
Band of Misfits.

22. rinting and Sustainability
• 3D printing with non
harmful chemicals.
• 3D printing generates
almost no waste during
manufacturing, and does
not require lubricants.
• 3D Printing can be used to
create replacement parts.

23. enges 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.
