What is 3D printing?
• It’s one rapid prototyping technologies
• It creates physical models from CAD and other
digital data—layer by layer
• It’s widely used, especially in product designing
• It reduces a lot of time and cost
• It’s a developing technology

What is prototyping?
Prototyping is a cycle
that producers or
designing teams make
models for end users to
test, evaluate, or debug,
and get feedbacks then
revise or redesign at the
pre-production or mock-
up period.

Rapid prototyping
• Stereolithography (1988)
• Fused Deposition Modeling(1990)
• Selective Laser Sintering(1992)
• 3D Printing (1997)

What do you expect to create next?
• A light bulb? A motherboard? or an iPod of
the nth generation?
-Go online, pay, and download the file
then…produce yourself!
-No packaging, no shipping,
no assembly lines needed!

Benefits of 3D Printing
• Lower cost of prototyping
• Allow more design iterations to choose
from
• Decreases length of the design process
• 3D Printers are small and affordable

Design Process
Concept Proof Of
Product Definition Development Production
Development Concept
• Costs of changing design or finding mistakes
increase the further into the design process you go
• 3D Printing helps you find mistakes early on to
save costs
12

Design Process
• Most critical phases of
design are early on
• In the first 10% of the
process nearly 80% of
the products total costs
are determined
• More early designs
mean better decision
making
13

Speed to Market
• 3D Printing increases efficiency late in the
design process
• Capable of developing parts for use in
functional prototypes
– Some models can produce pieces that can
withstand 60 psi pressure in field tests
• Cost of late entry to market is enormous
14

Small and Affordable
• Previous rapid
prototyping machines
often required their
own departments and
operators
• 3D Printers can fit
neatly near a
workstation
15

Future Savings
• A professor at USC has now created a
technology to eliminate the need of a laser
in 3D Printers
– Selective Inhibition Sintering (SIS)
• Potential cost savings of $10,000 to
$20,000 on the 3D Printing machines

3D Printing Success Story
Xerox Limited produces new-
generation printers, copiers, and
document centers. The Xerox
design team looked to a 3D
printer to help improve their
efficiency at producing
prototype parts by moving
away from the traditional
‘machining’ function and
moving more cutting edge rapid
prototyping equipment in
house.
21

3D Printing Success Story
Camera mounts for the
M1 tank and Bradley
fighting vehicle were
built and tested
directly from digital
files using the
Dimension 3D Printer.
22

3D Printing Success Story
A 3D printer proved to
be a valuable asset
and played a key role
in developing concepts
for the AMP Research
Alloy Fuel Door for
General Motors'
Hummer H2 sport
utility vehicle.

3D Printing Success Story
From furniture and
lighting to cosmetic
products and packaging,
Karim Rashid is a high-
profile industrial design
firm with an esteemed
reputation for
communicating a
contemporary view of the
world through its unique
designs.

3D Printing Success Story
Altimate Medical Inc.
manufactures standing
frames and mobility
aids for people with
disabilities, such as
spinal cord injuries,
muscular dystrophy,
multiple sclerosis and
cerebral palsy.

3D Printing Success Story
Bravilor Bonamat is
Europe's leading
manufacturer of coffee
machines for commercial
use. For more than 55
years, the family-owned
company has placed a
premium on innovative,
user-friendly design
concepts that have helped
the company distinguish
itself in the marketplace.

3D Printing Success Story
TaylorMade wanted pro golfer
Mark O’Meara to try out a new
set of irons, O’Meara asked to
use them at the 1998 Skins
Game. “We had one week to
produce two sets of irons—with
club designs still in CAD and no
tooling in place,” says Jeff
Blasius, TaylorMade’s senior
tooling engineer. “So we
created 50 wax patterns on our
3-D printer, sent them to the
foundry for casting and
finishing, and delivered them to
O’Meara on time. It was the
initial prototype test and Mark
won the Skins Game with
them.”

3D Printing Success Story
Guatemalan twins Maria
Teresa and Maria de Jesus
Quiej-Alvarez were born
joined at the head. The veins
draining the blood, were
interwoven and fed into each
others' circulatory system.
The most complex part of
the operation was to sort out
the veins and reroute the
twins' blood supply. Because
the blood vessels were
crisscrossed, tracking them
using standard, two-
dimensional x-rays was
impossible. 28

Conclusion
Nothing communicates design ideas faster
than a three-dimensional part or model.
With a 3D printer you can bring CAD files
and design ideas to life – right from your
desktop. Test form, fit and function – and
as many design iterations as you like – with
functional parts.
