4. INTRODUCTION with 3D Printing
3D printing is a modern
technology in which 3
dimensional objects are
printed from digital data.
Three dimensional object is
created by laying down
successive layers of material.
5. What is 3D Printing ?
3D printing or additive manufacturing is a method of
converting a virtual 3D model into a physical object.
The creation of a 3D printed object is achieved using
additive processes.
In an additive process a 3D object is created by laying
down successive layers of material.
6. History of 3D Printing
The first 3D printer was created in 1984 by
Charles Deckard Hull of 3D Systems Corp.
He named the technique as Stereo lithography
and obtained a patent for the technique in 1986.

Print head/extruder Building platform Building material
Electronics
8. How 3D Printing 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.
9. Current 3D Printing Technologies :- 1
Stereo lithography:- It is an additive manufacturing process
using liquid UV-curable photopolymer “resin” and a UV laser
to build parts a layer at a time.
10. Current 3D Printing Technologies :- 2
Fused deposition modeling (FDM):- It is an additive
manufacturing which uses hot semi-liquid extrude directly to
print objects.
11. Current 3D Printing Technologies :- 3
Laminated object manufacturing(LOM) :- In this, layers of
adhesive-coated paper, plastic or metal laminates are
successively glued together and cut to shape with a knife or
laser cutter.
12. Current 3D Printing Technologies :- 4
Selective laser sintering (SLS):- an additive manufacturing
technique that uses a high power laser (eg:-, CO2 laser) to fuse
small particles of plastic, metal , ceramic or glass powders into
a mass that has a desired 3-dimensional shape.
13. Materials Used
• Thermoplastics :
ABS,PLA(poly lactic acid),acrylic,
elastoplastics , nylon ,
polypropylene, polyethylene
,polyamide etc.
• Metolids:- Titanium, Stainless
Steel, and Tool Steel powders.
• Ceramics, glass ,resin, rubber.
• Composite powder.
•
•
•
•
ABS plus
The most commonly used ink
for all modern 3D Printers
14. ADVANTAGES
In Medical Field, Surgeons are using
3d printing machines to print body
parts.
3D printing allows artists to create
objects that would be incredibly
difficult,costly, or time intensive using
traditional processes.

15. ADVANTAGES
Product formation is currently the main use of 3D printing
technology.
3D Saves Time and Cost:
Creating complete models in a single process using 3D
printing has great benefits.
This innovative technology has been proven to save
companies time, manpower and money.
16. Challenges 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.
18. Future Scope
With today's 3D printers, if you lose your TV remote's battery cover you
can print a replacement battery cover. With tomorrow's, if you lose your
remote, you'll be able to print a new remote.
3D printers are always getting cheaper and better.
There is currently research going on to create 3D printers that could print
out organs for people in need of a transplant.
Within a decade, 3D printers will become commonplace in houses.
The benefits of such technology are endless
22. Conclusion
Relatively New Technology.
No restrictions on industry.
Significant decrease in product development cycle and costs.
Full effects on business and society still not know.
Resistance to change.
