Executive Summary
The application field of the 3D printing technology is extremely wide, from every detail
of human life to national security; almost all kinds of fields can experience its shadow. Its
application object can be in any industry, as long as these industries are providing 3D data
models or prototypes, a 3D printer can process almost everything. These industries, which have a
greater demand of 3D printers, include government, medical equipment, high-tech research,
education, manufacturing and so on. The reason why 3D printing can rapidly developed is
because 3D printing not only can save labor cost for companies, but also can shorten the
production time. In 2009, a famous hospital of Beijing created the treatments with 3D printing
spine. When the orthopedics director introduces this method, he said that they would sent spine
design drawings to manufacturers, a few hours later, they will be able to get the printing
produced. Besides, 3D printing can produce various irregularly shaped bones. No matter what
shape people want, as long as it can design out, 3D printers can achieve it for people. This
technology not only greatly improves the speed of doing things but also gives better results. This
report is a culmination of a research on 3D printing technology.
Introduction
3D printing is additionally named as added substance manufacturing as it alludes to the
way toward printing a three dimensional protest of any shape using computerized technology. It
is called added substance manufacturing in light of the fact that the printing is finished using
layers of materials which are set down in an unexpected way. This procedure is an advanced
method which varies in numerous courses from the machine techniques that were generally
utilized. The customary strategies depended on the techniques involving expulsion of materials,

for example, cutting. This is the reason they were known as subtractive procedures while 3D
printing is known as added substance process (de Jong and de Bruijn, 2013).
The 3D printing utilizes the advanced technology and these printers were initially
fabricated by China. These printers came in the late 1980's and as far back as then they have
been increasingly utilized everywhere throughout the world. In the beginning of the 21st century,
as the computerized technology turned out to be more prominent and propelled, the development
in the offers of the 3D printers was extraordinarily watched. The offers of these printers
increased in different parts of the reality where they were utilized for new and innovative
purposes. Step by step, as the deals and the demand developed, the expenses of these printers fell
massively since they were first produced. A portion of the reasons for which these machines
were utilized were in industrial utilizations, design, adornments, aviation, engineering, medical,
instruction, information systems and numerous others (Richards et al., 2013).
3D printing is the technology to create materials and objects using a sequential layers
technique. The materials which are produced by using the layering process can be anywhere in
the product life cycle. However, the subtractive methods of manufacturing objects can be used as
traditional methods in manufacturing.
Development of 3D printing
The technology that involves printing of three-dimensional objects made its way in the
year 1986. It was taken with much seriousness during that time until the year 1990 when great
scientists took interest in the technology with a view of change it could bring to the society.
Several aspects are involved in the technology with a major thing being the inputs on the design

software (Lee & Dai, 2017). The technology has undergone a series of transformation, and it is
being applied in different parts of the world impacting the social life of the individuals. Research
is still being carried out on further improvement to enable its use in the field of architecture.
The 3D printing technology is a technology that has undergone quite a series of changes
since the period of implementation. It involves the creation of printable 3D models with the use
of computer-aided design software (CAD) or through the use of what is called a 3D scanner. The
modeling process of 3D geometric data does not have a significant difference from the common
plastic applied in different parts of the world today. A process known as 3D scanning is applied
before printing, and it involves the collection and analysis of digital data in reference to the
shape of a real object. The complexity nature of both the manual and automated 3D printable
models to normal consumers is what has caused the emergence of the 3D printing places located
in different places (Sun et al., 2013).
The most interesting part of the concept is the printing part. Before the commencement of
the printing, the file that is known as the STL file must under processing that is a task performed
using the slicer software. The slicer does the conversion of the model into several systematic thin
layers and produces a command or rather instruction known as the G-code that is now sent to the
printer (Walther, 2015). The printer then systematically in accordance to the instructions lays
down the layers of the material used t produce the desired object. The major advantage of the
technology is that it can produce almost any desired provided the required instruction is well fed
to the printer.
Several changes have taken place in the quest to achieve more efficiency in the
application of the technology. The first development is on the provision of low-cost printers. In

the past, the 3D printers were extremely expensive, and the majority of the people willing to
invest in the same could not be able to afford a printer. The other development is a 3D modeling
software. In the past, the software used was complex and tough to use which is contrary to the
recent times where software development techniques has made it possible for local people to
understand how to generate a 3D model (Yazdi et al., 2016). These include software such as
Autodesk 123D and Google SketchUp. The other development is on the material that can be used
in the printer. After the introduction of the technology, only polymers and plastics could be used
as material. Technological advancement and research have made it possible to use other
materials such as paper, wax, gypsum, and metals among others.
Benefits of 3D printing
There are numerous advantages of 3D printing which is the reason it is tremendously
utilized as a part of the present reality. Numerous architects utilize the 3D printing techniques to
quickly plan the ideas and transform them into 3D models or fast prototyping. It additionally
takes into account the quick outline changes which empowers the fashioners to do their work
quickly and easily using the up and coming advancements. The makers are additionally
permitted to create the items quickly on demand instead of on expansive run, which likewise
increases the administration of the adequate measure of inventory and lessens the distribution
center space (Romano, 2013).
3D printing techniques can help the general population living in remote areas to create
the articles that would be inaccessible to them generally. 3D printing must be an onetime cost on
the grounds that once the planners and businesses have purchased the machinery for 3D printing;
they can spare a great deal of material and cash which is utilized as a part of subtractive
techniques of manufacturing. The material in this strategy is penetrated, cut and shaved off;

subsequently crude material can be squandered. 3D printing is favored additionally on the
grounds that it enables the articles to change the idea of manufacturing for example by allowing
the clients to download the documents utilized as a part of printing 3D protests in their own
particular homes including electronic devices (Vijayavenkataraman, Fuh and Lu, 2017).
3D printers can make numerous models and models from the PC helped plan drawings.
Architects to a great extent utilize these printers to make models, models and additionally the
final items. There are numerous things that come in the scope of these items. These things are
shoe outlines, wax castings for adornments making, furniture plans, instruments, blessing things
and toys. There are a few different things utilized as a part of the day by day life of individuals
which are created using 3D printing techniques. This causes the fashioners to make new plans,
quickly create them and make them alluring for the clients (Rouiller et al., 2013).
Not only these industries, but rather the flying and car industries likewise to a great extent
utilize the 3D printing techniques to create parts. Additionally, craftsmen utilize these printers to
influence figures and planners to make models for their activities. Archeologists make 3D
sweeps of delicate ancient rarities and then print the duplicate of the question. Similarly the
scientistss copy, for example, a skeleton of the dinosaur for show. 3D printing is utilized by the
doctors to make hearing guides, prosthetics, bone drafts, counterfeit teeth and they can likewise
imitate models using 3D techniques of organs, and internal structures of the body appeared in CT
outputs to get ready for medical procedures.
Fused deposition modelling
To begin with this is an additive manufacturing technology. It is used in various
applications namely production applications, modeling, and prototyping. The fused deposition
modelling also is one of the methods employed in 3D printing. The technology has existed

drawing back from 1980 by Scott cramp; the technology has proved effective over years by
applying the additive principles in its operation. It works by laying materials in layers, and a
metal wire or filament made of plastic is relaxed from a coil hence distributes materials to
produce apart (Hoy, 2013). The technology is termed as simple to explore and clean; it also
supports thermoplastic grade production that are mechanically and environmentally stable.
New HP 3D Printer technology
An added substance technology the 3D printing, objects are not created from the specific
option of material rather than the molding of subtractive machining. 3D creates objects from
cross-areas in the new 3D printer they are worked as a solid course of action or from
subcomponents. The new Hp 3D innovations have two awesome highlights they have machines
that smooth parts with excellent subtle elements and additionally create excellent quality (Visser
et al., 2013). Hp Multi-fly combination technology is the new brand and technology; it offers
lucrative administrations, for example, excellent speed and great control over properties and
parts found in other 3D printing techniques. It works through a format of a thin layer of material
in the working region. Moreover, it has a carriage that has a Hp warm Inkjet connecting left and
right, printing along the zone of work. It transforms each layer course of carriages for ideal
profitability.
Disadvantages of 3D printing
Though the overall production of products using 3D is cheaper as compared to
conventional techniques, people have to incur the cost of buying the printers and a computer in
order to be able to use the technology. The fact that new types or designs of 3D printers are been
developed everyday can be extrapolated to mean that these printers are developed in different
sizes. A particular size of a printer can therefore only print a product of a size that can fit in that

specific printer. In other words, an individual in need of producing products or merchandise for
commercial purpose, and of different sizes, has to buy different sizes of printers. This can be
very expensive (Barker et al., 2013).
There are also legal issues that arise in reference to 3D printing. An example given by
(Barker et al., 2013) focus on liability issues, for instance when a printed item causes damage or
injury to a human being or property. Questions arise on who ought to pay for damages in such a
case. Due to counterfeiting, a manufacturing company could be wrongly held accountable and
end up spending millions in litigation fees.
Nowadays, the development of technology always brings a lot of surprises and incredible things
to people. With the continuous development and innovation, technology gradually affects every
aspect of human life. Whether people are working or in everyday life, people cannot live without
the support of technology. Although the technology has begun to make so much contribution to
the business field, when 3D printing technology appeared, it allowed people to experience the
life-change by introducing the next generation technology.
Recommendations
Whatever we create utilizing 3d printing technology, similar to restorative field builds up
the organs or military creates automatons or specialists create development gadgets, it will be
relatively exceptionally modest than the first ones and with a few changes in the technology, it
will be extremely enhanced later on. 3D printing techniques are advancing day by day but yet
they have not been advances enough that they be used for mass production. Currently their speed
is slow and this limits their usage. There are many tools used to overcome this problem such as
by using machines that combine with printers and increase their speed. This can be to print the

multiple colors, multiple prints at the same time and using different polymers. The aim is to
increase the printing speed while printing multiple objects and using less cost of capital than two
machines as a single controller may be used. New printers also offer two print heads in order to
increase the speed and production quantity at one time.
The 3D printing technology is largely being used worldwide. It initiated in America but it
has a widespread range of its machinery and usage in China and Australia. Engineers and
industrialists have used the new technology in China as the revolutionary 3D printing
manufacturing was advancing. In order to initiate the advanced technology of 3D printing all
over a China, many universities such as Beijing University is working on a research which would
examine the industry sources that are a breakthrough for the 3D printing techniques to produce
large components for aircrafts.
Conclusion
To sum up, 3D printing can overcome some difficulties which traditional manufacture cannot
conquer, and produced a more complex structure. Indeed, in recent years, with the development
of technology, 3D printing has pioneered a breakthrough on medical applications. This is mainly
because the medical industry, especially in the field of restorative medicine, needs significant
character customization, little standard quantitative production. Thus, personalized, small batch
and high precision is exactly where the 3D printing technology advantage is. In detail, the
application of the 3D printing technology means creating a new way of the medical treatment. At
the beginning of 2010, when American researchers successfully printed an organ, it seems that to
directly print the human body is not impossible (Hsu, 2013). It is more similar to the cloning
technology. Patients will not reject organs that are printed out from 3D printers. It can also print
hands, teeth, hearing aids and so on. People have to admit that the power of technology is great

and cannot be ignored. In the future, 3D printers probably will do anything for people, for the
entire society or for the earth. People just need to offer an idea, some of the material, and a 3D
printer. Then every idea will become a reality. Moreover, in medical term, 3D printing
technology will introduce a new concept of human implantation, medical treatment, or organ
substitutes. The future of 3D printing definitely will be promising.
