2. INTRODUCTION
It is achieved using additive processes.
Additive process
an object is created by laying down successive layers of material
until the entire object is created.
Each of these layers can
be seen as a thinly sliced
horizontal cross-section
of the eventual object
3. INTRODUCTION
It is considered distinct from
traditional machining
techniques (subtractive
processes)
mostly rely on the removal of
material by drilling, cutting etc.
Since the start of the twenty-first
century there has been a large
growth in the sales of these
machines, and their price
dropped substantially.
4. WHAT IS 3D PRINTING? (ADDICTIVE MANUFACTURING)
A process of making
three dimensional
solid objects from a
digital file.
Performed by a
materials printer using
digital technology.
5. HOW DOES IT WORK?
It starts with making a virtual design of the object.
This virtual design is made in a CAD (Computer Aided
Design) file using
3D modeling program for the creation of a totally new object
3D scanner to copy an existing object
This scanner makes a 3D digital
copy of an object and puts
it into a 3D modeling
program.
6. HOW DOES IT WORK?
To prepare the digital file, the software slices the final model
into hundreds or thousands of horizontal layers.
When this prepared file is uploaded in the 3D printer, the
printer creates the object layer by layer.
The 3D printer reads every slice (or 2D image)
proceeds to create the object blending each layer together with no
sign of the layering visible
Resulting in one three dimensional object.
7. WHAT DOES IT USE FOR?
The technology is used in the fields of
Jewelry
Footwear
Industrial design
Architecture
Engineering and construction
Automotive
Aerospace
Dental and medical industries
Education
Geographic information systems
Civil engineering
8. SPECIFIC TECHNOLOGY: CLOTHING
3D printing has spread into the world of clothing with fashion
designers experimenting with 3D-printed bikinis, shoes, and dresses.
Commercial production
Nike is using 3D printing to prototype and manufacture the 2012 Vapor
Laser Talon football shoe for players of American football
New Balance is using 3D manufacturing custom-fit shoes for athletes.
9. HISTORY
In the history of manufacturing, subtractive methods have often come first.
The province of machining (generating exact shapes with high precision)
was generally a subtractive affair, from filing and turning through milling
and grinding.
Additive manufacturing’s earliest applications have been on the toolroom
end of the manufacturing spectrum.
For example, rapid prototyping was one of the
earliest additive variants and its mission was
to reduce the lead time and cost of developing
prototypes of new parts and devices, which
was earlier only done with subtractive toolroom methods
(typically slowly and expensively).
10. HISTORY
Additive methods are moving even further into the production end of
manufacturing.
Parts that formerly were the sole province of subtractive methods can now in
some cases be made more profitably via additive ones.
The real integration of the newer additive technologies into commercial
production is essentially a matter of complementing subtractive methods
rather than displacing them entirely.
11. FUTURE
Manufacturing firms will need to be flexible, ever-improving users of
all available technologies in order to remain competitive.
This technological development will change the nature of commerce,
users will be able to do much of their own manufacturing rather than
engaging in trade to buy products from other people and corporations.
12. FUTURE
3D printers capable of outputting in color and multiple materials
already exist
Continue to improve to a point where functional products will be
able to be output.
With effects on energy use, waste reduction, customization, product
availability, medicine, art, construction and sciences, 3D printing will
change the manufacturing world as we know it.
13. NEWS: ANOTHER 3D PRINTING PROJECT FOR
THE WORLD CUP
3D printing artists and companies are very much
into this year’s World Cup, and of course the
technique enables people to be creative and come
up with some funny World Cup inventions.
We got another World Cup initiative and it comes
from Ultimaker.
14. NEWS: ANOTHER 3D PRINTING PROJECT FOR
THE WORLD CUP
3D printing artists and companies are very much
into this year’s World Cup, and of course the

up with some funny World Cup inventions.
We got another World Cup initiative and it comes
from Ultimaker.
The company releases 3D printable mascots, which
you can download for free and print them out.
They created files for 16 unique country-related
Mascots, and you can print out the mascot that
suits your own country.
