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

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”

Library Resources

Mind Map

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

Do you know some places using 3D printing 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.

Future Development

More research and development on 3D printing Technology

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

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
