3. 3D printing is a process of
making a 3 dimensional
solid object of virtually any
shape from a digital model,
also known as
ADDITIVE MANUFACTURING.
WHAT IS 3D PRINTING?
3D PRINTER

5. PROCESS
1.ADDITIVE MANUFACTURING –
Process where successive layers of material are
laid down in different shapes.
It is done by the process of
EXTRUSION DEPOSITION
It lays down material in layers; a plastic filament
or metal wire is unwound from a coil and supplies
material to produce a part. Polymers like ABS are used.
GRANULAR MATERIALS BINDING
The technique fuses parts of the layer,
and then moves the working area downwards, adding
another layer of granules and repeating the process
until the piece has built up.

6. ADDITIVE MANUFACTURING(CONTD.)
LAMINATION
Sheet is adhered to a substrate with a heated roller.
Platform with completed layer moves down out of the way.
Fresh sheet of material is rolled into position.
Platform moves up into position to receive next layer.
The process is repeated.
PHOTOPOLYMERIZATION
is used to produce a solid part from a liquid where
liquid polymer is exposed to light from a DLP projector under
safelight conditions. The exposed liquid polymer hardens.It is
also known as STEREO LITHOGRAPHY.

7. 2.RAPID PROTOTYPING
Technique used to quickly
fabricate a scale model of a
physical part.
3.SUBTRACTIVE PROCESSES
Removal of material by methods
such as cutting or drilling.

8. APPLICATIONS
Creating open-source scientific equipment to create open
source labs.
Reconstructing fossils in paleontology.
Replicating ancient and priceless artifacts in
archaeology.
Reconstructing bones and body parts in forensic
pathology.
Reconstructing heavily damaged evidence acquired from
crime scene investigations.
The technology currently being researched for building

10. 3D Printing technology could revolutionize and re-shape the
world. Advances in 3D printing technology can significantly
change and improve the way we manufacture products and
produce goods worldwide.
