1. (a new emerging technology)

2. Imagine a near future in
which a device connected
to your desktop prints a
SOLID OBJECT!!!!!!

3. Applying a 2-D image on
a 3-D surface
Additive
manufacturing or 3D
printing is a process of
making a three-
dimensional solid object
of virtually any shape
from a digital model. 3D
printing is achieved using
an additive process,
where successive layers
of material are laid down
in different shapes.

Printing

5. Modeling:
Additive manufacturing
takes virtual blueprints
from computer aided
design (CAD)
or animation modeling
software and "slices" them
into digital cross-sections for
the machine to successively
use as a guideline for
printing.

6. Printing:
To perform a print, the
machine reads the design and
lays down successive layers of
liquid, powder, or sheet material
to build the model from a series
of cross sections. Printers melt
or soften material to produce
the layers. These layers, which
correspond to the virtual cross
sections from the CAD model,
are joined together or
automatically fused to create
the final shape. The primary
advantage of this technique is
its ability to create almost any
shape or geometric feature.

8. The main considerations
in choosing a machine
are generally speed, cost
of the 3D printer, cost of
the printed prototype,
and cost and choice of
materials and color
capabilities
Printers that work
directly with metals are
expensive. In some
cases, however, less
expensive printers can
be used to make a
mould, which is then
used to make metal
parts.

9. ABSplus, the most commonly used ink for all
modern 3D Printers, is a production-grade
thermoplastic that gives models the ability to
perform just like production parts in real-world
functional testing.

11. Ability to revolutionize manufacturing and
society
 Shift from mass production to customized products for
consumers
Printing generates almost no waste during
manufacturing, and does not require lubricants
Expansion beyond simple prototyping
 Printers have ability to print final products

12. Food industry

15. 3D printed Jaw

16. 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.

17. 3D printing is an expanding
technology which may soon
start an industry in which
everyone has the possibility of
being a manufacturer.
