8. Most people have heard of 3D printing which implies
that 3D printing is quite famous nowadays, especially
among teenagers and people in employment.

Q3: When did you hear about 3D printing?
10. •However, we can see that only less than 20% heard
about 3D printing before 2010, and most of them
heard about it in 2012 and 2013. Although 3D printing
is developed in early years, it became popular among
public within these few years only.

Q6: Which application(s) do you know about?
15. • The most famous application is rapid prototyping as
we can see from this chart. Some applications are
not very familiar to them. ‘Rapid manufacturing’,
‘Art’, ‘Education and research’ are also popular
choice. Actually, 3D printing can be applied to many
fields. But some fields are not very known to public.

Q7: When was 3d printing invented?
17. •Only 30% of them answered correctly that 3D
printing was invented in the 80s. It did not turn out
surprisingly that the majority believed 3D print was
invented in the 90s because the technology has only
become hot spot since the 90s.

Q8: Below were achievements made in 3D printing during the 21st
century. Which one was achieved in priority?
20. • From the normally distributed data above, we can see
that respondents were not familiar with the history of
3D printing. Nonetheless, plenty of them (30%) picked
the correct answer. It is believed that respondents
thought 3D print was priori applied in medicine field
rather than other industries, such as manufacturing
industry century.

Q9: Stereolithography is the basic
methodology behind 3D printing for making
solid objects by successively “printing” thin
layers of the ultraviolet curable material one
on top of the other. Before 3D printing was
invented, Chuck Hull, the German inventor, was
actually working as an engineer in a small
business that made tough table coatings

23. •We let respondents read a few sentences about the
theory behind 3D print before answering the question
above to see if they could relate the theory to the job
Chuck worked before 3D print was invented. It turned
out half of them answered correctly. We can conclude
that 50% of the respondents acknowledged Chuck was
originally working as an engineer, figuring out how to
make use of ultraviolet to make tough table coatings.

Q10: Which sneakers are probably made by 3D printing?
26. •The answer is bottom one. From the above graph,
there are mainly three answers in the question, upper
one, middle one and bottom one. Existing 10
respondents believe that the upper one is the answer,
while 9 people think that middle one is the ideal one.
Extremely, there is only 1 person answering bottom
one as the solution. The reason maybe the difference in
the bottom one with other 2 is quite obvious. Thus, the
bottom one is extremely having a small amount of
people answering for.

Q11: What is the form of 3D printing's copy?
28. •The digital copy is the answer. The graph presents 3
form of 3D printing’s copy, digital copy, real copy,
virtual copy. 10 people and 9 people have a belief that
are digital copy and real copy respectively. On the
other hand, virtual copy just have 2 people thinking of.
The reason maybe 3D printing involving digital things,
so others consider digital copy as the answer.

Q12a: What is another function of 3D scanner other than
making a 3D digital copy of an object?
30. • The correct answer is putting it into a 3D modeling
program. This question is about another function of 3D
printing rather than making a 3D digital copy of an object.
9 citizens feel putting it into a 3d modeling program. 6
residents believe putting it into a virtual design made in a
CAD. On the other hand, just 5 people fill putting it into an
existing object in the question. The possible reason of the
name of 3d printing , letting them having a prerequisite
concept of 3d modeling program is another function about
3d printing.

Q12b: Which is the service about 3D printing?
32. •The correct answer is Shapeways. Services about 3D
printing in this questions have 3 answers, Shapeways,
Instagram, Whatsapp. The majority of respondents, 14
people believe Shapeways as corrent answer, while 4
people and 2 citizens believe whatsapp and instagram
as answers respectively. The major reason that they
are corrent is that they know the services of whatsapp
and instagram, which they use in their daily life.
