1. 3D PRINTING Dream it ,

2.  Method of creating 3D OBJECTS
from a digital file.
 Additive
Manufacturing.
 Opens up new
opportunities for
mass customization.
WHAT IS IT?

3. “A passive consumer to an active
creator !”

4. MAKING IT HAPPEN.
1. Create a CAD model:
 Ready-made design (Internet)
or
 Own CAD design
2. Convert CAD model
to .STL file format
3. Execute the slicing
software
4. Print the desired
model !

6. Regardless of what printing or slicing
technologies are employed , ANY 3D
object can be printed in the following
manner:

Printing Techniques
There are several methods of 3D printing , but
the most widely used process is :
Fused Deposition Modeling (FDM)
• Uses Thermoplastic filament which is heated
to its melting point.
• Extruded layer by layer to create 3D object

8. +
HOW FDM WORKS ?
FDM printers use 2 kinds of materials:
1. Modeling material , which constitutes the final product.
2. Binder , which supports the object being printed.
During printing ,
• Binder , in the form of filaments is unwound from
the coil & fed through an extrusion nozzle which
melts the filaments and extrudes them on the
base.

9. +
Contd...
• Nozzle & base  controlled by a computer that
translates the dimensions of an object into X,Y & Z
coordinates  the nozzle and base follow this
during printing.
• Extrusion nozzle moves horizontally , vertically
draws cross-section of the object.
• Thin layer of plastic cools & hardens  binds to
the layer beneath.
• Base is lowered ! Room for next layer of plastic.

11. APPLICATION DOMAIN

12. Motor Vehicles:
• Spare parts can be printed out !
• printed cars !
Many MNCs like the BMW , Boeing ,
F1 group utilize 3D PRINTING for
printing out their vehicle parts !

13. WORLD’S FIRST 3D PRINTED
FORMULA RACE CAR TESTED
IN HOCKENHEIM
For those who have doubted 3D printing durability and
what could be built with the technology, the news about
3D printed formula car might come as a shock. 16
student engineers from a Belgium based Group T hit the
headlines with “Areion” – World’s first formula car made
almost entirely of 3D printed parts.

14. Consumer Goods:
• Almost anything from toys to intricate design articles
can be printed !
• Makes teaching easy !
• Prototype making made easy ! Architects , Engineers
can now easily build models of the required design !

15. Medical:
• Prosthetic limbs for handicapped.
• 3D printed organs, making wonders !
• Face reshaping, rebuilding !

17. Fashion Industry
3D printing has also
revolutionized the fashion
industry.
As you can see, the
costume worn by the
model is a 3D printed
attire, put together 17
separate 3D printed
parts.

22. Will 3D
PRINTING
change the
world ?

23. AMAZON launches huge 3D
printing section !!

24. NASA to send 3D printers into space
in 2014 !

25. CHINESE COMPANY builds 3D
PRINTED HOUSES quickly !!
Builds 10 houses in ONE day.

26. 3D PRINTING OPEN SOURCE
REVOLUTION
• The RepRap project , a British initiative to develop a
3D printer capable of printing its own components !
• RepRap is an acronym for Replicating Rapid
Prototyper !
• As an OPEN DESIGN , all designs produced by the
project are released under a FREE SOFTWARE
LICENSE.

27. • The aim of the project is to make 3D
printers affordable and available to a
large population .
• The RepRap 3D printing kits start at a
cost of Rs.30K in contrast to the
commercial 3D printers that start off at a
huge Rs.6 lakh !
