This research work takes a look at the rapid
development of the 3D printing community,
and the changing patterns of production,
keeping especially in mind the expectations
that 3D printing is a part of an emerging
“revolution in manufacturing”.
• Printing is a process for reproducing text and images,
typically with ink on paper using a print press.
•Creates a product through adding materials to the object.
•Adds material layer by layer until printing is finished.
•Allows for complex and intricate designs.
•
• A method of Additive Manufacturing that adds material
to an object layer by layer to create the final product.
•Imagine a near future in which a device connected to your
desktop prints a SOLID OBJECT!!!!!!
 Selective laser sintering (SLS)
 Stereo lithography (SL)
 Fused deposition modeling (FDM)
 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).
Stereolithography 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.
• CAD (Computer Assisted Design) Programs help users
create STL Files for the 3D Printers to read.
• STL (STereoLithography) file format – a file format which
uses many little triangles to make a 3 dimensional plot of
the objects intended surface.
• Fused deposition
modeling (FDM) is an
additive manufacturing
technology commonly used
for modeling, prototyping,
and production applications
a) Preparation :
• Once you click “3D print “ from Z-print , the printer initiates
the pre build routine
• First it warms the air inside the printer and creates optimum
operating environment.
• At the same time , it fills the ‘Build Chamber’ with 1/8th inch
layer powder ( so that finished parts rest on it).
b) Printing :
• Once the pre-build is complete , the printer begins
printing the layers created in the Z-print software.
• The machine deposits 0.1mm thick layer of powder from
the ‘Hopper”.
• The ‘Print Carriage’ then moves across this layer
depositing the binder.
• The binder solidifies the powder in that cross
section of the model.
• The piston below the ’Build Carriage ’ lowers the
powdered bed by 0.1mm , preparing the next layer.
• The process repeats until the model is complete
c) Depowdering/Recycling :
• When finished the model, it is suspended in the powder to
cure.
• At the end of curing time , the machine then automatically
removes most of thepowder around the model by vaccum
pressure.
• The loose powder is pneumatically conveyed through the
system for reuse.
1. Medical industry
2. Food preparation
3. Fashion and retail
4. Defense and space
5. Game and entertainment
6. Architecture
• 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.

  • 9. • CAD (Computer Assisted Design) Programs help users create STL Files for the 3D Printers to read. • STL (STereoLithography) file format – a file format which uses many little triangles to make a 3 dimensional plot of the objects intended surface.
  • 10. • Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications
  • 11. a) Preparation : • Once you click “3D print “ from Z-print , the printer initiates the pre build routine • First it warms the air inside the printer and creates optimum operating environment. • At the same time , it fills the ‘Build Chamber’ with 1/8th inch layer powder ( so that finished parts rest on it).
  • 12. b) Printing : • Once the pre-build is complete , the printer begins printing the layers created in the Z-print software. • The machine deposits 0.1mm thick layer of powder from the ‘Hopper”. • The ‘Print Carriage’ then moves across this layer depositing the binder.
  • 13. • The binder solidifies the powder in that cross section of the model. • The piston below the ’Build Carriage ’ lowers the powdered bed by 0.1mm , preparing the next layer. • The process repeats until the model is complete
  • 14. c) Depowdering/Recycling : • When finished the model, it is suspended in the powder to cure. • At the end of curing time , the machine then automatically removes most of thepowder around the model by vaccum pressure. • The loose powder is pneumatically conveyed through the system for reuse.

  • 16. • 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.
