3D Printing: Brief History of 3D Printing, How It Works, Applications and Impact on Education

1. 3D PRINTING

2. Definition
• Creating 3D solid objects using
additive process
• Additive: successive laying down of
layers of material

3. Brief History
• 1983 – Charles Hull invents
stereolithography
• Stereolithography: From digital data
to tangible solid object
• 1988 – Technology made public
• 1996 – 3D printer was used

4. How It Works
1
• Create design using CAD or
modeling software
2
• Send design to 3D printer in .STL
format
3
• Choose material (e.g. plastic,
paper, rubber, metal)

5. How It Works
4
• Filament material is fed to print
head
5
• Printer heats or melts filament
material
6
• Material is sprayed or squeezed
layer by layer

6. How It Works
4
• Object is bound by laser
5
• Printer heats or melts filament
material
6
• Material is sprayed or squeezed
layer by layer

7. Advantages
• Revolutionize manufacturing by
enabling individuals to create
products
• Various materials are used
• Plastics can be recycled
• Applications in all industries

8. Applications
Health/Medicine
• Produce hearing aids, leg braces
and even skin grafts

9. Applications
Prototyping
• Faster and more accurate creation
of models

10. Applications
Manufacturing
• Tools, musical instruments, furniture
and even bikes can be homemade

11. Applications
Fashion/Retail
• Faster production of unique clothes
and shoes

12. Applications
Aeronautics
• Real-time creation of food and tools
in space

13. Education

14. Education
• Design & technology classes in UK
primary schools and high schools
use 3D printers

15. Education
• Design & technology classes in UK
primary schools and high schools
use 3D printers

16. Education
• 3D printer company Makerbot aims
to have 1 3D printer per school in
U.S.

17. Education
• More accurate and realistic models
for Science classes

18. Education
• Easier and faster model-making for
engineering, architecture, and art
students

19. Education
• Encourages creativity, critical
thinking and excitement for students

20. Education
• Starbase Elementary Program
