3. Introduction
3D printer is a modern technology in which 3 dimensional
objects are printed from digital data
Three dimensional object is created by laying down
successive layers of materials.
4. History
The technology for printing physical 3D object from digital data
was first developed by Chuck Hull in 1984. He named the
technique as Stereo lithography and obtained a patent for the
technique in 1984.
5. What is 3D Printing?
3D Printing is a form of additive manufacturing in which
components are fabricated in an additive fashion by adding
successive layers of materials together.
It is also know as:
Rapid Prototyping
Additive manufacturing.
3D printing or additive manufacturing 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. In
an additive process an object is created by laying down
successive layers of material until the entire object is created.
7. How 3D Printing work
1. A person created a of an item using a computer aided design
Software Program.
2. The CAD information is send the printer.
3. The Printer forms the item by depositing the materials in
layers, Starting from the bottom layers on to a platform. In
some cases light or lasers used to harden the materials.
10. Modeling
Additive Manufacturing tasks virtual blueprints form computer aided design (CAD) or
animation modeling software and “Slices” them into digital cross-sections for the
machine to successive use a guideline for printing.
11. Printing
The perform a print, The machine read the design and lays down successive
layers of liquid, powder, or sheet materials to build the model from a series of
cross sections. These layers, Which cross ponds to the virtual cross section
from the CAD model, are join together or automatically fused to create the
final shape. The primary advantage of this technique is its ability to create
almost any shape or geometrical feature.
12. Finishing
Though the printed product resolution is sufficient for may applications,
Printing a slightly oversized version of the descried of in slandered resolution,
and the removing materials with a higher-resolution subtractive process can
archive a higher-resolution.
13. Different Methods
Stereo lithography
Selective laser sintering (SLS)
Fused deposition modeling (FDM)
Ink-Jet 3D Printing
14. Value proposition of 3D Printing
Fabrication on demand
Shorter Product development time due to rapid prototyping
Less reliance on logistics
Mass Customization
Caters to each individual’s wants and needs instead of mass production and
consumption
15. Advantages
Print movable parts
Print Items in remote locations
Ability to send items over internet and print out at home
Plastic use is strong
16. Disadvantages
No regulations on what can be made example weapons
Kids could print out dangerous Items
Provide advantages for criminals
Counterfeiting
Expansive

18. Conclusion
Nothing communicates ideas faster than a three dimensional parts or model.
With a 3D printer you can bring CAD file and design ideas to life- right form
your desktop. Test form, Fit and function as and many design variations as
you like with functional parts.
