1.0 Chapter 1: Introduction
Innovations in printers, especially 3D printers have had several valuable impacts on the industry
(Wu, Wang & Wang, 2016). Application of 3D printers in construction and management faces
several challenges. Some of the research problems have been discussed and detailed out in the
literature review. Analysis of research questions have been undertaken here to analyse the
potential impact of 3D printers in constructions with analysis of future scope and challenges.
2.0 Research Questions
2.1 Introduction
The inquiries of this examination are intended to analyse the requirements presented through
previous chapter. The scope of this analysis contains to address the exploration issues
characterized in the past section for analysis of 3D printing impact on the construction industry
(Gosselin et al. 2016).
Q1: What is the current perception of the 3D printing in construction industry?
One of the real finding of the scholarly analysis revealed through the papers that address the 3D
printing technology design provides that there is no experimentally information accumulation
about the impression of 3D in construction. Most of the flow coordinated in 3D printing design
endeavors to apply itself in construction and management is in accordance to the researcher’s
observation and assessment. In any case, there are not very many gathered and analytical

information attempting to concentrate and feature the fundamental issues that the 3D printing
confront primary issues by improving the present undertaking design systems.
To conduct this inquiry, a review has to be undertaken construction and management. To arrive
at appropriate results is to be able to quantify the present impression of the undertaking 3D
printing in term of the need in construction and management.
H1: Most of the construction engineers perceive 3D printing is importance in construction
industry.
Q2: What are the variables that might influence the acknowledgment of having 3D printing
techniques to be applied across construction industry?
Such inquiry may be replied by proposing the accompanying inquiries and planning the correct
speculations to answer them.
Q2a: How would the size of the organization determine the agreeableness of the 3D
printing?
In this inquiry the extent of the organization where the 3D printing stakeholder have encountered
their endeavor design experience; might influence whether they would have a positive
discernment toward having the techniques connected with construction and management.

H2a: The span of business measure impacts the impression of the 3D printer stakeholder
on the construction.
Q2b: Do 3D printers stakeholders see more positive aspects recognition about application
of the endeavor to construction engineering practices and systems than those with less or
no 3D printing approaches?
H2b: The ability of 3D printing to impact on the construction and management.
Q2c: Does more reliance of 3D printing on the present endeavor on construction contrarily
influence her/his acknowledgment impression of the 3D printing?
H2c: The reliance of big business on 3D printers in construction and management big
business design structures impacts the construction and management.
Q3: What are the 3D printing Motivators?
There are present diverse motivations to adopt 3 D printers in construction; the significant reason
is the progress and technological adaptations in businesses. In order to construct a logical
rundown of motivators various ones proposed by different scholars has to be incorporated into
Page | 5

the system plan as primary undertaking design motivators. Some of the advantages of motivators
are highlighted.
a. 3D printing responsiveness to business and IT changes.
H3a: A large portion of enterprises in the field of construction are undertaking design 3D
printing framework to be more receptive to the business and IT changes.
b. The disruptive technologies as cloud and versatile figuring challenges.
H3b: A large portion of the construction industry ought to be more adaptive to the
disruptive technologies.
c. Construction engineering constant change and criticism.
H3c: A large portion of the construction engineers stresses on the need of having nonstop
changes and input into the system.
Q4: What are the 3D printing Enablers?
3D printing enablers includes the strategies that can impact construction and management. 3D
printing has various principles and framework that help develop perspective of application on
construction and management. It may they are still so potential to be center standards to grow
such assessment structure.

1. The most noteworthy need is to customer satisfaction by means of through right on
time and consistent conveyance of profitable.
H4a1: The vast majority of the 3D printing agree that consumer loyalty through early
conveyance is an empowering agent to have a coordinated construction and management.
2. Deliver working undertaking construction, from a long time to two or three months,
with an inclination to the shorter time lines.
H4a2: A large portion of the 3D printing accept that frequent delivery is an empowering
influence on construction and management.
4. Construction and management stakeholders (customers and construction engineers)
must cooperate every day all through the task.
H4a3: The greater part of the 3D printers arise through that cooperation between
stakeholders is an empowering agent to have an effective construction engineering.
2.2 Summary of the Section
In this section the examination questions required with address the exploration issue; and
appropriately by planning the required speculations to test and answer these inquiries. To
outwardly abridge the examination inquiries and theories we built up the accompanying outline
to delineate the connections between the exploration issue, inquiries, and speculations.

2.3 Data Gathering Instruments
A questionnaire was designed keeping in mind the end goal to be circulated to the examination
populace test. To encourage a simple correspondence with the members the online questionnaire
tool from qualtrics.com was adopted (Appendix 1).
2.3.1 Target Populace Criteria
The objective populace was targeted to construction engineers, from the both genders, 18 years
of age or more, with no less than 1 years of involvement in construction and management.
2.3.2 Population Example Casing
The focused on test has been set to achieve 160+ from the above characterized target populace,
before the finish of the overview opening period (20 January 2018 till 15 April 2018) to get total
contributing 149 participants.
2.3.3 Questionnaire Correspondence
Keeping in mind the end goal to guarantee exact aftereffects of the survey, a watchful segment
procedure of the questionnaire participants needs to occur. Such cautious determination has been
accomplished by welcoming invitees who have demonstrated profiles that match the objective
populace criteria; this has been finished by auditing the profiles of the invitees on LinkedIn as a
standout amongst the most solid and endorsed proficient person to person communication media.
In the wake of evaluating the profile of the potential invitee and having a positive after-effect of
