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 preproduction or mock-up
period.

Rapid prototyping

Stereolithography (1988)
 Fused Deposition Modeling(1990)
 Selective Laser Sintering(1992)
 3D Printing (1997)
Why 3D printing has become the most
popular one?
Ans: faster and more inexpensive

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

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

WORKING OF 3D PRINTER







The computer file travel to the 3d printing
machine
A layer of powder spread into the 3d printer
Temperature is raised(laser)
A laser harden powder and the model gets
its shape
The new layer of powder is spread out and
the process is repeated many times
The model is returned out of the printer and
cleaned
Model is finished by hand

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

11
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
12
Small and Affordable
Previous rapid
prototyping
machines often
required their own
departments and
operators
 3D Printers can fit
neatly near a
workstation

13
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.

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.

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.
