1. Literature Review
The construction and medical industries
stand to benefit greatly from the new
possibilities afforded by the rapid
development of 3D printing technology. It is
impossible to optimize medical care, surgical
planning, or building design without accurate
3D models. However, verifying the precision
of 3D models is a challenging task with farreaching consequences for health treatment
and building projects. The purpose of this
examination of the literature is to inquire into
the significance of accurate 3D models and to
introduce Shape Vault, a digital library made
to meet the crucial needs of medical and
construction experts. We hope to show how
valuable Shape Vault's methodology is by
studying related research topics and similar
systems. Shape Vault's mission is to supply
reliable and high-quality 3D models for these
critical domains.
1.1 Research Domains
This research delves into the
importance of accurate 3D models in the
medical and construction and even the
engineering field (Jiang & Ma, 2020; Kirpes
et al., 2022) , The pioneering uses of 3D
printing in medicine and construction show
the technology's revolutionary potential
across many fields. Patient-specific implants,
anatomical models, and medical gadgets are
now easily manufactured thanks to 3D
printing's
revolutionary
impact
on personalized medicine. Msallem et al.
(2020)conducted a study on 3D-printed
mandibular models, using advanced digital
analysis techniques to reduce error sources
and generate high-precision reference files
via optical scanning. The objective of the
comparative analysis of various 3D printing
technologies was to evaluate the precision of
these models for routine clinical applications.
The findings highlight the importance of
accurate 3D models in medical applications,
which facilitate surgical planning and
patient-specific treatments with dependable
outcomes. The importance of precision is
further
emphasized
by
additive
manufacturing (AM) technologies, in which
path planning has a significant impact on the
surface quality and dimensional precision of
printed products (Jiang & Ma, 2020).
Construction has also adopted 3D printing as
a cutting-edge alternative for architectural
prototyping, bespoke designs, and building
components. Xia et al., (2019)explore the
significance of path planning in achieving
precision and efficiency in constructionrelated 3D printing projects. Construction
engineers can optimize design iterations and
test structural integrity prior to the physical
construction process by using highly precise
3D models. Not does this reduce costs. It also
improves the overall reliability and
performance of the product. Additionally, the
construction industry benefits greatly from
the versatility of 3D printing as it allows for
complex designs that would be challenging to
achieve using construction methods.
Although the research highlights the
relevance of precise 3D models in both the
medical and construction areas, a lack of
knowledge and expertise in making these
models can be a significant element
contributing to the issues that are
experienced, and this can be one of the
reasons why the research was conducted
(Parmit K. Chilana, 2018). Because of the
intricacies of 3D modelling and the
complicated nature of the software features
that are necessary to produce correct designs,
professional skills and training are required.
According to Desolda et al., (2023),
inexperienced users who are not acclimated
to the workflows and geometry involved in
3D modelling may find the learning curve to
be overwhelming, which may result in errors
and inaccuracies in the 3D models they make.
The current limitations of 3D printing
technology exacerbate the difficulties
associated with precision in medicinal and
building applications. Although 3D printing
has made advancements in years it still has its
limitations. The time required to complete a
3D manufacturing procedure is a major
limitation(Attaran, 2017). Depending on the
model's complexity and size, the printing
process can take anywhere from hours to
days, impeding rapid prototyping and
production efficacy in industries that are time
sensitive.
CGTrader stands out for its commitment to
real-life accuracy in 3D models, making it a
preferred choice for industries that require
precise measurements and dimensions.
However, the platform's specialization in
architectural and interior designs raises
certain limitations. While the models on
CGTrader can serve as valuable prototypes
for creating visual scenes of the final product,
their usability as reliable sources for finished
products may be hindered by the lack of
complete information. As a result, it is
essential to exercise caution and expert
supervision before employing CGTrader's
models in manufacturing processes.
1.2 Similar Systems
Numerous platforms in the realm of
digital libraries and 3D model repositories
cater to the needs of professionals and
researchers from diverse disciplines. Each of
these platforms, CGtrader (Kalytis, M.
2011.), Sketchfab (Cédric. P. 2012),
TurboSquid (Matt. W. 2000), and the
proposed Shape Vault, possesses unique
features and capabilities. While some of these
websites offers a specific 3D model in
anatomy like Turobsquid form professional
and certified creators the same goes for
CGtrader in the construction and
architectural industries, most of them are
used for prototypes or educational purposes
they are not critically reviewed for real life
usage and have a lack of necessary
information(Angrish et al., 2019).
Figure1. CGtrader Architectural 3D models
In same case, Sketchfab is a versatile
platform for professionals, artists, and
educators due to its extensive collection of
3D models from a wide range of disciplines.
Its user-friendly interface and interactive
features enhance the overall experience for
3D design exploration and collaboration.
Nevertheless, Sketchfab's association with
cinematic settings and artistic creations
frequently prioritizes aesthetics over
accuracy. Consequently, it may not
consistently provide the precision required
for specialized medicinal and construction
applications.
Figure2. Sketchfab 3D printable models
Turning our attention to TurboSquid, this
platform serves as a popular hub for 3D
artists to showcase and sell their creations. Its
vast library encompasses a wide range of 3D
models, making it a valuable resource for
professionals in various industries. However,
the accuracy of sizes and dimensions can
vary depending on individual artists'
practices, potentially posing challenges for
applications
that
require
precise
measurements, while some could be highly
precise and would fit the expert’s needs but
in other cases could visually look right but the
measurements inside of the 3D files could be
twisted and not the right proportions and that
makes it hard to monitor all the times and
could lead to potential errors.
Figure3. Turbosquid Anatomical Models
In response to these limitations Shape Vault
acknowledges that it may lack the scale and
diversity of some of its competitors.
However, the platform’s primary purpose is
to be a trusted source for accurate and
printable 3D models, supporting businesses

models.
In the medical domain, physicians, surgeons,
medical researchers, dentists, and healthcare
professionals seek precise and realistic 3D
models for applications such as surgical
planning (Kim et al., 2018), medical
education, and patient-specific treatment.
These professionals rely on accurate
representations of anatomical structures and
medical devices to optimize diagnostic and
therapeutic interventions, ultimately leading
to improved patient outcomes.
Similarly, within the construction industry,
architects, engineers, and construction
professionals seek highly precise 3D models
for architectural prototyping, structural
analysis, and building complex component
design (Zhang et al., 2019). The construction
sector benefits immensely from 3D printing's
ability to create intricate and complex
geometries, but this necessitates models with
precise measurements to ensure seamless
integration with existing projects and
construction processes.
Moreover, researchers and academics from
both domains play a pivotal role in shaping
the evolution of their fields. Their demand for
accurate 3D models extends beyond practical
applications
to
include
research,
experimentation, and scientific exploration.
Reliable 3D models are vital tools for
investigating new medical procedures,
analyzing building designs, and conducting
simulations in controlled environments.
2.2 Sampling method
Purposeful sampling will be used in
the development of Shape Vault. Approaches
like this help ensure that the collection of 3D
models on the platform is of quality and
suitable for printing. To cater specifically to
the needs of professionals in building fields
researchers can employ sampling techniques
to narrow down models that are most
relevant, for these areas.
Shape Vault will collaborate with industry
specialists as professionals working in
construction and medical sectors to initiate a
deliberate sampling process. By consulting
experts such as doctors, surgeons, architects,
and engineers from fields we will learn about
the types of 3D models essential for their
work. These specialists require a level of
precision and reliability when dealing with
anatomical structures, medical equipment,
architectural components, and construction
designs.
In addition, Shape Vault will work to form
alliances with the industry's top providers of
3D models for use in healthcare and building.
These trained designers and artists can make
photorealistic 3D models fit for professional
use. Together with Shape Vault, they'll be
able to compile a specialized assortment that
meets the exact standards of the healthcare
and building sectors.
The number of professional needed to start
the idea suggested would be roughly around
5 experts on each field, by interviewing 5
experts in the medical field and 5 experts on
the construction field that would give a good
incite oh what are the different point of
views, what are the specific things experts are
looking for, what are the most needed objects
needed for this idea to work What are the
most used technologies or gadgets needs to
be considered first before initiating in
designing the model.
For this kind of idea to work it needs to be
monitored all the time with newer updates so
having more and more interviews and
consultations is a must, but to start up a small
number of people are required, if we were to
take too much information at once there
might be conflict in points of view and there
will be a confutation on what suggestion is
right or wrong and that is why having a small
number at first is the ideal option.
2.3 Data Collection Method
In the context of Shape Vault
gathering data is essential as it helps us gain
an understanding of the intricate details
involved in developing accurate 3D models.
We will obtain data by collaborating with

experts and qualified 3D model designers to
conduct interviews and seek their advice, in
fields like medicine and construction. These
interviews will primarily focus on gathering
information about structures, medical
equipment, architectural details and building
layouts.
Shape Vault can ensure that the 3D models
curated by the platform comply to industryspecific measuring practices and quality
standards
by
conducting
qualitative
interviews with professionals in these fields
to gain a deeper understanding of the unique
issues and requirements encountered by these
groups.
Furthermore, qualitative data will be
acquired through the evaluation and
verification of preexisting 3D models. The
platform's team of expert evaluators will do a
qualitative evaluation of the models by
comparing their dimensions, proportions, and
scale to real-world measurements and
industry standards.
