The document discusses the history and principles of 3D printing. It provides details on the different 3D printing technologies including stereolithography, fused deposition modeling, and selective laser sintering. Applications of 3D printing discussed include industrial design, agriculture, and defense/aerospace. The document outlines the 3D printing process and common materials used such as plastics and metals.

3. • 3D printing is a process of making
three dimensional solid objects
from a digital file.
• The creation of a 3D printed
object is achieved using additive
processes.
3D + Printing = 3D Printing or “Additive Manufacturing”

4. 1984
Charles (Chuck) Hull developed the first 3D printer and named the technique as Stereo
lithography.
1990
Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) were introduced.
1993
MIT patented another technology, named "3 Dimensional Printing techniques", which is similar to the
inkjet technology used in 2D Printers.
2005
Z Corp launched first high definition color 3D printer.

5. Additive Manufacturing
Subtractive Manufacturing
Additive Manufacturing could reduce
energy use by 50% and reduces
material costs by up to 96% compared
to traditional manufacturing.

6. 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.

7. A person creates a 3D
image of an item using a
CAD software program.
The CAD
information 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?

8. Methods of 3D Printing
1.Selective LaserSintering(SLS)
2.Stereolithography
3.Fused DepositionModeling(FDM)
Stereolithography
FDM

9. 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.

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

11. 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.

15.  Designers use 3D printers to quickly create product models and prototypes.
INDUSTRIAL DESIGN

16. • In producing agricultural machinery and spare parts.
• In producing working tools and customized elements for building
farms.
• In producing irrigation systems, pottery and other customized objects for
agriculture.

• Prototypes for different types of sprinklers can be designed and then tested in the gardens and
fields.
Self-designed drip irrigation structures can also be
printed
