2. What is 3D printing?

3. What is 3D printing?
• Making three dimensional solid objects from
a digital file.
• Created by laying down successive layers of
material until the entire object is created.

4. How does 3D printing work?

5. How does 3D printing work?
• Starts with making a virtual design of the object
you want to create.
• Use CAD file using a 3D Modeling program
• Use of a 3D scanner
• 3D scanner makes a 3D digital copy of an object.

6. How does 3D printing work?
• Microsoft and Google enabled their hardware
to perform 3d scanning, a great example
is Microsoft’s Kinect (Using Kinect Fusion)
• A clear sign that future hand-held devices like
smartphones will have integrated 3d scanners.

7. How does 3D printing work?
• 3D modeling software “slices” the final model
into hundreds or thousands of horizontal layers.
• When the sliced file is uploaded in a 3D printer,
the object can be created layer by layer.
• The 3D printer reads every slice and creates the
object, blending each layer with hardly any visible
sign of the layers, with as a result the three
dimensional object.

8. Processes and Technologies

9. Processes and Technologies
• Not all 3D printers use the same technology.
1) Vat Photopolymerisation
2) Material Jetting
3) Binder Jetting
4) Material Extrusion
5) Powder Bed Fusion
6) Sheet Lamination
7) Directed Energy Deposition

10. Processes and Technologies
Most Common Technologies
• Selective Laser Sintering (SLS)
• Fused Deposition Modeling (FDM)

11. Selective Laser Sintering (SLS)

12. Selective Laser Sintering (SLS)
• The ability of SLS to produce several pieces at
one time.
• Good choice for Direct Digital Manufacturing
(DDM) of products requiring strength and heat
resistance.

22. 3D Printing Industry

23. 3D Printing Industry
Medical industry
– Improved quality of care through 3D printed implants
and prosthetics never before seen.
– Tissue engineering applications where organs and
body parts are built using inkjet techniques.
– Layers of living cells are deposited onto a gel medium
and slowly built up to form three dimensional
structures

24. Medical Industry

25. 3D Printing Industry
Aerospace & Aviation industries
– For a large part, be derived from the
developments in the metal additive
manufacturing sector.
– NASA for instance prints combustion chamber
liners using Selective Laser Melting.

26. Aerospace & Aviation industries

27. 3D Printing Industry
Automotive Industry
– Simple concept models for fit and finish checks
and design verification
– Functional parts that are used in test vehicles,
engines, and platforms.

28. Automotive Industry

29. Industrial Printing

30. Industrial Printing
Rapid Prototyping
– Manufacturers use 3D printers in their design process to
create prototypes for traditional manufacturing and
research purposes.
– For example, Nike uses 3D printers to create multi-colored
prototypes of shoes. They used to spend thousands of
dollars on a prototype and wait weeks for it.
– Now, the cost is only in the hundreds of dollars, and
changes can be made instantly on the computer and the
prototype reprinted on the same day.

31. Industrial Printing
Rapid Manufacturing
– Manufacturers use 3D printers for short run
custom manufacturing.
– In this way of manufacturing the printed objects
are not prototypes but the actual end user
product.

32. Personal Printing

33. Personal Printing
• Mainly for hobbyists and enthusiasts.
• Rapid development within this new market
printers are getting cheaper and cheaper.
• Prices typically in the range of $250 – $2,500.

34. Future

35. Future
• 3D Printing technological development will change the nature of
commerce.
• End users will be able to do much of their own manufacturing
rather than buy products from other people and corporations.
• 3D printers capable of outputting in color and multiple materials
already exist.
• Will effects on energy use, waste reduction, customization, product
availability, medicine, art, construction and sciences.
• 3D printing will change the manufacturing world.
