3. Overview of 3D Printing
“3D printing” or “Additive Manufacturing” takes digital input
in the form of Computer Aided Design (CAD) model and creates
solid, three dimensional parts through an additive, layer by
layer process.
4. Types of Manufacturing
Additive Manufacturing
Subtractive Manufacturing
Additive Manufacturing
could reduce energy use by
50% and reduces material
costs by up to 96% compared
to traditional
manufacturing.
5. General Principles
1.Modelling:It takes virtual blueprints from modeling software
and “slices” them into digital cross-sections for the machine to
successively use as a guideline for printing.
2.Printing:To perform a print, the machine reads the design
from an .stl file and lays down successive layers of liquid,
powder, paper or sheet material to build the model from a
series of cross section.
3.Finishing
6. A person creates a
3D image of an
item using a CAD
software program.
The CAD
informatio
n is sent
to the
printer.
The printer forms the
item by depositing the
material in layers—
starting from the
bottom layer—onto a
platform. In some
cases light or lasers
are used to harden
the material.
How Does It Work?
7. Methods of 3D Printing
1.SelectiveLaser
Sintering(SLS)
2.Stereolithography
3.FusedDeposition Modeling(FDM)
Stereolithography
FDM
8. Selective Laser Sintering
It is an additive manufacturing technique that uses a high
power laser( for eg. CO2 laser) to fuse small particles of
plastic, metal, ceramic or glass powders into a mass that
has a desired 3D shape.
9. Stereolithography
It is an additive manufacturing process that works by
focusing an ultraviolet (UV) laser on to a vat of
photopolymer resin.
10. Fused deposition modeling
It build parts layer-by-layer from the bottom up by heating
and extruding thermoplastic filament. Used for modelling,
prototyping and production applications.
14. Applications
1.Concept Modeling :This lets
small design and engineering firms
extend their reach by testing out
more ideas .
2.Functional Prototyping: It
helps in creating amazingly
realistic
prototypes with the look and feel
of a real product.
Example:
Lamborghini, while developing its
new flagship model Aventador has
made extensive use of 3D printing
technology to build a
functional prototype of the car.
15. 3.Manufacturing Tools:
Quick, low-volume tooling and
custom fixtures give
manufacturers the flexibility to
embrace more opportunities.

17. Future Scope
1.Complex Engine parts.
2.On demand parts in Space.
3. Aircraft Wings.
4. 3D Printing as a Service(3DPaaS)
20. Conclusion
3D Printing is an expanding technology which
may soon start an industry in which everyone has
the possibility of being a manufacturer.
3D Printing has a lot of possible benefits to
society, although the products created must be
regulated.
