4. Introduction
A process of making three dimensional solid objects from a
digital file
Make use of 3D printing to make
conceptual models, functional prototyping, manufacturing tools ,
production tools, mold manufacturing and end-use parts
Several ways to do 3D printing:
Selective laser sintering, fused deposition modeling,
stereolithography

5. Project Information
 Search Strategies
1) Subject Directory
 offers a collection of links to Internet resources submitted by site creators or
evaluators and organized into subject categories
 useful  conducting general research or want to find resources recommended by
experts and evaluators.
2) Search Engine
 a searchable database of Internet files collected by a computer program
 looking for a particular web site, have a specific research question, or are looking
for the most current information
** Use Specific Words - 3D Printing
** Use Research Operators - “3D Printing”

6. Library Resources

7. Mind Map

8. Online Survey
 Purposes of the survey:
- To understand how much the general public
know about the 3D printing technology
- To understand how people feel about future
development of 3D printing technology

now?
Yes
No
We can see that most of the interviewees have not tried to
use 3D printer. And this can show that 3D printing is still
not quite common to general public nowadays.

Which of the following is/are the application(s) of 3D
printing? (Can Choose more than one answers)
From this, we can see that people think that 3d printing can
make everything that we want to produce, especially for the
art use and medical use. People are most familiar with
these two functions of 3D printing.

e.g. Find more new materials
 Refine the printing skill
e.g. Print more complicated objects
 Find some ways to reduce cost and enhance
durability
 Make it more environmentally friendly and energy
saving
 Suggestion: Rocket parts

33. Conclusion
 Most of the people know about 3D printing
technology, but only limited to basic level
 Minority of people have used 3D printing before
 Majority of people have high expectation on its
future development and bring great contribution
to the future world
