3D printing, or additive manufacturing, is a technology that creates three-dimensional objects by layering materials, with its history dating back to Charles Hull's creation of stereo lithography in 1984. Various methods, such as selective laser sintering and fused deposition modeling, have emerged, enabling applications in fields like medicine, architecture, and art. Despite its advantages, including reduced product development times and costs, the full impact of 3D printing on business and society remains uncertain.

2. Introduction
3D printing is a form of additive manufacturing technology where a three
dimensional object is created by laying down successive layers of material.
It is also known as rapid prototyping, is a mechanized method whereby 3D
objects are quickly made on a reasonably sized machine connected to a
computer containing blueprints for the object.
3D Printers are machines that produce physical 3D models from digital data by
printing layer by layer. It can make physical models of objects either designed
with a CAD program or scanned with a 3D Scanner.
The basic principles include materials cartridges, flexibility of output, and
translation of code into a visible pattern.

3. Definition: 3D + Printing = 3D Printing
3D Printing is a phrase used to describe the process of
creating three objects from digital file using a materials
printer, in a manner similar to printing images on paper.

4. Printing Process
Printing is a process for
reproducing text and images,
typically with ink on paper
using a print press.

5. History of 3D Printing
• The technology for printing physical 3D objects from digital data
was first developed by Charles Hull in 1984. He named the
technique as Stereo lithography and obtained a patent for the
technique in 1986.
• While Stereo lithography systems had become popular by the end of
1980s, other similar technologies such as Fused Deposition
Modeling (FDM) and Selective Laser Sintering (SLS) were
introduced.

6. Different Methods
Selective Laser Sintering (SLS)
Stereo Lithography
Fused Deposition Modeling (FDM)
Laminated Object Manufacturing

7. SLS Method
Selective Laser Sintering (SLS) is an additive manufacturing
technique that uses a high power laser (for example, a carbon
dioxide laser) to fuse small particles of plastic, metal (direct metal
laser sintering),ceramic or glass powders into a mass that has a
desired 3-dimensional shape).

9. Stereo Lithography
Stereo lithography is an
additive manufacturing
process using a vat of liquid
UV-curable photopolymer
”resin” and a UV laser to build
parts a layer at a time.

10. Fused Deposition Modeling
Fused deposition modeling
(FDM) is an additive
manufacturing technology
commonly used for modeling,
prototyping, and production
applications.

11. Laminated Object
Manufacturing
Laminated object
manufacturing (LOM) is a
rapid prototyping system
developed by Helices Inc. In
it, layers of adhesive-coated
paper, plastic or metal
laminates are successively
glued together and cut to
shape with a knife or laser
cutter.

13. 3D Printing Capabilities
As anticipated, this modern technology has smoothed the path for numerous new
possibilities in various fields. The list below details the advantages of 3D printing in
certain fields.
1.In Medical Field, Surgeons are using 3d printing machines to print body parts for
reference before complex surgeries. Other machines are used to construct bone grafts
for patients who have suffered traumatic injuries.
2.Architects need to create mockups of their designs. 3D printing allows them to
come up with these mockups in a short period of time and with a higher degree of
accuracy.
3.3D printing allows artists to create objects that would be incredibly difficult,
costly, or time intensive using traditional processes.

14. Success
Stories
Auto parts: For example, parts of "Formula 1" car engines, are
made by direct laser sintering of metal;
Aircraft parts: F-18 (fight aircraft) tube for the control
system environment;
Individual Orthodontics: The company Align Technology uses
the 3D Printing to generate accurate individual dental braces for
hundreds of thousands of patients worldwide by stereo
lithography from 3D-scans of the mouth.

17. 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.
