seminar on 3d-printing.

2. 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”.

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

4. •Creates a product through adding materials to the object.
•Adds material layer by layer until printing is finished.
•Allows for complex and intricate designs.
•

5. • 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!!!!!!

6.  Selective laser sintering (SLS)
 Stereo lithography (SL)
 Fused deposition modeling (FDM)

7.  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).

8. 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.

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.
