Q3 ANALYSIS

• 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.

SURVEY RESULTS Q4: Where did you get the information about 3D printing?

From schools

From friends or families

From the TV

From the Internet

from the mold making industry

From newspaper

From radio

Q4 ANALYSIS

• And, more than half of them choose ‘From the Internet’ in this question. We can see that the Internet plays an important role in spreading a new innovation.

SURVEY RESULTS Q5: Have you ever heard of any applications of 3D printing?

Few90%

Q6 ANALYSIS

• 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 ANALYSIS

• 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.

SURVEY RESULTSQ8: Below were achievements made in 3D printing during the 21st century. Which one was achieved in priority?

Printed Organ Printed blood vessels

Printing gold and silver Usable prosthetic leg

SYRVEY RESULTSQ8: Below were achievements made in 3D printing during the 21st century. Which one was achieved in priority?

a. First printed organ

b. Printed blood vessels

c. Printing gold and silver

d. First usable prosthetic leg (Prosthesis: a device, either external or implanted, that substitutes for or supplements a missing or defective part of the body. )

Q8 ANALYSIS

• 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.

SYRVEY RESULTSQ9: 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 using ______________ lamps.

Q9 ANALYSIS

• 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.

SURVEY RESULTSQ10: Which sneakers are probably made by 3D printing?

SURVEY RESULTSQ10: Which sneakers are probably made by 3D printing?

Upper one

Middle one

Bottom one

0 2 4 6 8 10 12

Q10 ANALYSIS

• 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.

SURVEY RESULTSQ11: What is the form of 3D printing's copy?

Digital copy

Real copy

Virtual copy

0 2 4 6 8 10 12

Q11 ANALYSIS

• 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.

SURVEY RESULTSQ12a: What is another function of 3D scanner other than making a 3D digital copy of an object?

Putting it into a 3D modeling program

Putting it into a virtual design made in a CAD

Putting it into an existing object

0 1 2 3 4 5 6 7 8 9 10

12a ANALYSIS

• 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.

SURVEY RESULTSQ12b: Which is the service about 3D printing?

Shapeways

Instagram

Whatsapp

0 2 4 6 8 10 12 14 16

Q12b ANALYSIS

• 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.
