This document summarizes a group presentation on 3D printing. It provides background on the invention of 3D printing in the 1980s. It then describes how 3D printers work by layering materials and their common components. The document discusses applications of 3D printing in various fields like manufacturing, medicine, and engineering. It also summarizes the results of a survey that found most respondents think 3D printing is useful but not yet common. Finally, it discusses future opportunities for 3D printing including home use and medical applications but notes it still has room to grow.

5. Background Information of 3D printing
• Chuck Hull, an American
• Invented it in 1983
• After one year, he applied the patent for 3D printing
• In 1986, he founded the 3D System Corporation
• He was nominated for the European Inventor
• Award in 2014
This technology is a great success!!

6. What is 3D printing
• 3D Printing - an additive manufacturing process that creates
a solid three-dimensional object from a digital design.
• Production of the objects - done by adding materials layer by
layer
• Most common desktop 3D printer types:
1. used filament fabrication (FFF)
2. fused deposition modeling (FDM)

7. 3D printer components
• Mechanical components:
1. Print bed - surface on which the objects are printed
2. Bed surfaces - help the plastic attach on during printing &
allow it to detach when done
3. Filament - plastic that used by the printer

8. 3D printer components
4. Extruder - the core of the printer
• Electrical components:
1. Motherboard (takes command)
2. Stepper Drivers (for running stepper motors)
3. User interface (direct control)

9. Applications
• 3D printing is used in many fields
• Manufacturing field (e.g. car, aircrafts)
• Medical field
• Engineering
• Textile
• Food

10. Survey Results and Analysis
• 13 Questions
• Sampling size : 50 respondents

11. Survey Results and Analysis
•Half of the respondents
think they know little
about it
•Still not common

12. Survey Results and Analysis
- Use Internet to get
information
- Details of 3D printingis
the most available on
the Internet
- Traditional social
mediaseldomtalk
about it

DO YOU THINK 3D PRINTING IS USEFUL?
• Most of the respondents
think that 3D Printing is
useful

14. Survey Results and Analysis

15. Survey Results and Analysis
• Over 50%of the respondents
think3D printingis not very
commonnowadays.
• Also, it may take a longtime
to 3D print something.
• Improvements

16. Survey Results and Analysis
• Although a large number
of respondentsthinkthe
3D printingis useful, not
all of themagree that the
traditional production
industry will be replaced.

17. Survey Results and Analysis
- Only few respondentswill
buy a 3D printer even if it
is expensive
- Other factors
-> inability to use the printers
-> size of the printers

18. Survey Results and Analysis
• A quarter
of respondents think
the 3D printers can be
soldat a lower price
• Next thingis that the
developers should
install more functions
to the printers

19. Future development and opportunities
1. Possibly own their 3D printers at home one day
2. Build a dream house without hiring any construction
workers
3. The production of replacement or artificial organs

20. Conclusion
• Still at its growing stage
• It will probably replace the traditional manufacturing
industries one day
-> allow faster object production
-> make people’s life simpler and more convenient
Believe me, the technology will revolve and eventually
reach its peak! 
