2.  A process for making a physical object from
a three-dimensional digital model, typically
by laying down many successive thin layers
of a material.
 This also called as additive manufacturing.

3. History of 3d Printing 3D PRINTER-DESIGNER
 This technology
developed by Charles
Hull in 1984. He
named the technique
as Stereo lithography
and obtained a patent
for the technique in
1986.

 Cad means ->computer
aided design which
performs creation,
modification, analysis, or
optimization of a design.

5.  Stereo lithography(SL).
 Fused deposition modeling(FDM).
 Selective laser sintering (SLS).
 Multi-jet modeling (MJM).

6. Fig:2
 In this process layers
are added by
curing photopolymers
with ultraviolet
light lasers. Hull
defined the process as
a "system for
generating three-
dimensional objects by
creating a cross-
sectional pattern of the
object to be formed.

7. fig:3
 FDM begins with a
software process which
processes an STL file
(stereolithography file
format).

8. fig:4
 Selective Laser
Sintering (SLS) is an additive
manufacturing technique
that uses a laser as the
power source
to sinter powdered material
(typically metal), aiming the
laser automatically at points
in space defined by
a 3Dmodel, binding the
material together to create
a solid structure

 Ink jet printing comes
from the printer and
plotter industry where
the technique involves
shooting tiny droplets
of ink on paper to
produce graphic
images.

12.  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.

13.  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.

14.  Misusage of this technology by anti-social
persons like terrorists causes great effect.
 Unchecked production of dangerous items.
 imitations of size, raw material.
 Cost of printers

15.  We can give life to our ideas from our
desktop.
 Not time consuming process.
 3D printing can provide great savings on
assembly costs.
 3D printing could even challenge mass
production method in the future.
