Disadvantages Of 3d Printers
Amazing machines
3–D print technology has significantly altered over the years. With the help of Computer–Aided Designs, millions of items can be created via printing
them 3–Dimensionally. Whatever you can imagine, you can make! These magnificent machines have become more affordable and extremely useful,
making them a revolutionary tool in the arts of Medicine, Science, and Engineering. From prosthetics to everyday items (plates, mugs, etc.) these
machines can make them all easily and affordable; but nevertheless, can a machine like this have no drawbacks or complications?
With such high demands, the 3D printer market is expected still to grow "as high as 17.2 billion dollars by 2020". Though costs have dropped and

With this taking place, their factories become more eco–friendly by not wasting their materials and ceasing the waste products of them, while saving
time and money. But not only that, some even create full–scale cars using 3d printers.
AS well as sustaining the ability to produce prosthetic limbs, 3d printing is also extremely useful for creating artificial organs for needy patients in
hospitals. But not only organs, but skin, bone, cartilage, blood vessels, surgical tools as well as even hearts and stem cells can just as well be made by
these magnificent machines.
As 3d printing is "additive manufacturing", consequently, it's products are printed from the ground up. So therefore there's no waste of materials as
opposed to other forms of production. Another buff of having a 3d printer at–hand would be using it to design and construct spare parts for everyday
items. Say, your favorite coffee mug's handle breaks; with the right measurements, you can have a replacement part designed and printed accordingly,

The scan software estimates the relative size of the object, then produces a virtual model, adding error to the product. This error causes an
overestimation of the original object 's size, resulting in an oversized model (Pinto). Errors leading to oversized models must be kept to a minimum,
especially for models destined for the medical field. Some models are made to replicate the body structure of patients in order to provide surgeons
with a model to simulate the surgery beforehand (Petzold). These models include the structure of critical veins and areas that must be avoided to
prevent complications during surgery (Petzold). It is critical that the model accurately represents the position of such critical points so during
pre–surgery simulation/planning surgeons can construct a feasible method to avoid these areas. To increase model accuracy, accurately represent
critical features and minimize the amount of overestimation scans of objects should be taken using the maximum amount of reference points the
software and scanner allow (Pinto). The second method of attaining a .stl file does not involve estimations allowing the model to maintain the desired
geometry. The model is made directly in a CAD program then uploaded directly to the slicing software. This software slices the design into the many
layers that

3d Bone Printing And Its Effects On The Practice Of Medicine

The kidney printed for the transplant was not able to be used as it was not a live organ and it couldn 't function as a human kidney would. Researchers
by their nature are eager to embrace new technology the medical 3D printing industry has evolved in the past years. Today the researchers are trying to
3D print bones that can be transplanted in replacement of an injured bone."As of now, the only patient to benefit from the new printer is a
rat"(Abram). The 3D printed bones have not experimented on humans yet. So far the 3D printer has been used to print bones that can be implanted
into rats. The material used to print this bone was the rat bone itself. The 3D printing technology has advanced in the field of medical science by
improving health care.
The design of a 3D printer is a challenge as it involves many interacting subsystems from different areas. 3D printers involve mechanical parts that
are controlled by embedded controllers and are driven by power electronics. The motors in 3D printers are used to provide motion within 3 axes, that is
the x, y, and z. Sensors are used for end stops, which are used as interlock safety devices for the x, y, and z–axis to maintain the motion within the
distance allowed. The printer also involves a 3D scanner that is used to scan the injured bone of the individual. The printer replicates the 3D picture that

With these new advancements, doctors and engineers can now print living tissues into any shape or form to create new organs or new body parts.
Now that doctors can print up new organs, the backlog on kidney transplants to be reduced to almost none (Mukherjee). These organs have been
developed and soon to be implemented into transplants across the industry. Along with new organs, new body parts can be created for amputee
victims or anyone else who is need of a prosthetic limb. Although the industry already has realistic looking parts, with the use of tissue printing, the
parts can now have real skin to touch and possibly even have hair grow on the limb. The uses don't just stop at body parts either, doctors have
replaced a skull with 75 percent printed material (Mukherjee) and were successful with the operation. 3D printing also is used in the medical
industry for new tools or replacements. Dr. Tarek Loubani is the man who used a 3D printer to fix the shortages of stethoscopes in Gaza (The
Associated Press). Dr. Loubani used a 3D printer to print a fully functional stethoscope that doctors say "works just as good" (The Associated Press).
These new stethoscopes can be produced at a fraction of the cost of normal stethoscopes which helps eliminate a shortage of supplies. The entire

3D printing technologies are changing the way we produce objects. 3D printing is part of a process known as an additive manufacturing, where an
object is created by adding layer by layer. Additive manufacturing allows designers create complex parts for machines.
Extruder is a part of the printer which draws and melts the filament. If the pressure and speed are kept constant then the material flow is maintained
uniform. The material should be in a semi–solid state when it comes out from the nozzle and should be able to solidify and bond to the previously
extruded material to form the 3D object.
How does it work?
The first step in 3D printing is to create a blue print of the object. Makerbot replicator 2 have a spool in the

Abstract. Additive layer manufacturing regarded as the driver of a "third industrial revolution" can give the industry and science significant benefits
over existing manufacturing techniques. Yet it has some disadvantages, with one of them being a wide variation of mechanical properties of additive
manufactured parts. The mechanical behavior of produced components is known to be profoundly affected by a microstructure, which, in turn, depends
on the material and process parameters. In this paper, a two–dimensional numerical model is developed to simulate the grain structure evolution during
laser additive manufacturing. The cellular automata method is applied to describe the grain growth. The Goldak's heat source model is used to define
the heat input during laser melting. Selective laser melting process, which involves sequential deposition and melting of powder layers, is considered.

Computer Printing And Its Effects On The World Essay
Introduction
In 1984, 3D printing, also known as additive manufacturing was introduced to the world. A three–dimensional (3D) printer works just as an inkjet
printer, but instead of ink, certains type of material would be deposited layer by layer until the anticipated object is constructed. A decade later, this
semi–new technology was used to make parts that could be printed overnight with minuscule imperfections. Then, in the late nineties, 3D printing
advanced to printing organs with the patient's own cells so there would be less danger of the body rejecting the new part (Cite). This led to a medical
breakthrough, an event that would ensure extended life to its owner: a functional 3D printed kidney. The 3D printed kidney was efficient in filtering
blood and producing urine, thus encouraging engineers to strive for more discoveries. By today's day and age engineers could not only mechanical
pieces, such as aircrafts, cars and such, but medically organic part as organs, blood vessels and finally, prosthetics.
The production of printed prosthetics is aimed at the younger generation because of their ever–changing bodies. According to Kids Health, "Kids tend
to get taller at a pretty steady pace, growing about 2.5 inches each year. When it comes to weight, kids gain about 4 to 7 lbs," (Gavin, 2015). The
production of these prosthesis will be at a low cost, accurate and made in a timely manner. These staggering opportunities allow many individuals to

Upcomng Advances in 3D Printing
Introduction [271]
3D printing is a means of revolutionising almost any and all aspects of life. The potential to bringing into the physical world anything that can be
conceived in the mind (and created on a computer) brings a myriad of variety ; expanding markets and capabilities, whether new or improving
products and processes that are already in practice. 3D printers are falling in price as the technology improves and the want for them increases making
the ability to create anything domestically more practical , this would allow for an influx of material that would be hard to control or monitor, this can
include guns, weapons and equipment for drugs manufacture along with the mundane domestic items like faucets, plugs or pots. Such a possibility
would involve the morals of the manufacturer and the ethics of the wider collective that have an input on the advancements, though there are other
limitations that play a part in the progression of 3D printing that are independent of ethics. As the technology and concept has the potential to create
anything, it doesn't not yet have the capability to do so therefore the anticipation of the possibilities is the only preparation the 3D printing industry can
do, as a result I shall conduct an investigation looking at the extent of ethical and moral influences as well as physical and scientific limitations and how
they could limit any potential advancements, in accordance with the resulting benefits from some upcoming advancements in

The Technology Of 3d Printing
Three–dimensional (3D) printing is an exciting feat of modern human innovation emerging at the dawn of a new industrial uprising, however as we all
know, with all beneficial revolutions come vindictive consequence. 3D printable firearms are a stain in a revolution that could potentially change the
world as we know it. These weapons are a reality and they are under much scrutiny in the engineering and technological world with major implications
on public safety and loopholes in federal regulations. The emerging technology of 3D printing has been under development for many years now and the
potential is highly underestimated. The latent violence that 3D printed weapons – or more specifically – guns could impose on society is frankly
frightening. The controversy is generated from two different sides: one side takes the stance that these guns will be used as undetectable firearms
for crime and could give anyone with a printer access to a lethal weapon; the other side believes that just as an individual could go to a hardware
store and buy tools to enact violence in some form, a 3D printed firearm is no different. Part II will present the cutting edge technology of 3D printing,
the uprising and how it has evolved. Part III introduces good and bad the 3D printing technology carries, and the reality of 3D printed firearms and
their evolution. Part IV analyses the implications that 3D printed firearms have on current and future regulations and society as well as plausible

What Properties Are Used Plastic 3 D Filament?
The thousands upon thousands of amorphous thermoplastics in existence provide many options as to what properties a printed object can have. Both
ABS and PLA are commonly used plastic 3–D filament, but they are used for very different reasons. ABS has a higher melting temperature and
printing temperature than PLA probably due to the extra entanglement cause by the branching chains in ABS. Without a properly heatedprinting bed,
this could cause warping and shrinkage of the ABS object when lower layers cool too fast. Those lower layers will shrink due to cooling while
layers are still being added. As higher up layers cool, they too will shrink and cause the lower layers to morph even more than they have. Though
this makes working with ABS the slightest bit hard, the final product has many benefits. The object produced is fairly strong due to its "superior
layer bond." When the object does not have a large temperature as it is being printing, the layers develop a strong adhesion to each other. The object is
more resistant to impact and heat. ABS is the ideal polymer to make things such as toys, automotive parts, and electronic housing. The strength and
durability of the material will help keep the toy together as a toddler throws it about. The heat resistance can tame heat possibly produced by
electronics it stores. ABS can also be more flexible based on the composition of its monomers. PLA has decent strength and durability without the
flexibility and heat resistance ABS has.

Additive manufacturing (AM) methods in product development and manufacturing is projected to grow over 300% within the next 10 years
(Columbus). The increase in AM methods is a result of AM's ability to create products with complex internal and/or externalgeometry in a timely and
cost effective manner (Columbus). Members of the medical field rely on AM to create models for pre–surgery planning as well as structures inserted
into patients (Petzold).
Background
AM can create complex geometries; however the process struggles to maintain geometric accuracy of products (Ameta). Geometrically inaccurate
products manufactured for use in the medical field may subject patients to unnecessary complications that could have been avoided if geometric
tolerances were kept. Here I review, research that studied the parameters of the AM process and the role each parameter plays in maintaining or

PCs dislike people; they can't simply take a gander at a 3D demonstrate and basically tell their companion 'Mr. 3D Printer' what to print. Parts of 0s
are included, which means parcels and heaps of PC code. Once a 3D demonstrate is planned or just downloaded off of a storehouse like Thingiverse,
the record (these for the most part have augmentations, for example, 3MF, STL, OBJ, PLY, and so forth.) must be changed over into something many
refer to as G–code.
G–code is a numerical control coding utilized for the most part for PC helped producing (both subtractive and added substance fabricating). It is a
dialect which advises a machine how to move. Without G–code there would be no chance to get for the PC to impart where to store, cure or sinter a
material amid the creation procedure. Projects, for example, Slic3r are required keeping in mind the end goal to change over 3D demonstrate

The Fundamental Concept Of Additive Manufacturing Essay
3. What is 3D printing?
3 D printing also known as additive manufacturing or stereolithography or rapid prototyping has been predominantly explored for the past few years.
3D printing technology is called additive manufacturing because the material is built from scratch, without any loss in existing volume of an object by
chipping, drilling or cutting. (Tony Hoffman, 2016). The fundamental concept ofadditive manufacturing is printing an object by successive deposition
of layers of various materials. Before an object can be 3D printed, it first has to be sliced into thousands of horizontal and vertical planes in Computer
Aided Design (CAD). There are similar software like CAD which are used for the purpose of 'Slicing '. Some of these software are CAM– Computer
Aided Manufacturing and 3D Scanner. These horizontal and vertical planes together make up the 3D model of the object. Once a virtual design of the
object is prepared, also called as 'the feed', a file in the '.stl' format is provided to the printer which then prints the desired object. Though the basic
outcome of 3D printing is same, different technologies have been developed as per its need in the industry. Based on personal requirements, an object
can be customized on small as well as large–scale.
As 3D printing continues to grow and evolve, a number of companies are establishing their mark in this area. 3D printing not only involves the
printing of an object, but it is a step by step process ultimately

Another fear, held by both companies and consumers alike, is the possibility of counterfeit products. Individuals would have the power and opportunity
to print and sell different products to buyers who believe they are purchasing and paying for the original and genuine product. Those who oppose
leaving 3D printers unrestricted also anticipate that it could lead to intellectual property laws being eradicated completely, as the government loses
complete control over 3D printing all together.
The current difference between all other creative mediums and 3D printers at this time is that all the others are well established and known by the
public throughout the world. 3D printing is still so young, it was only in the 1980's that engineers began to use 3D printers in their work (Barnett).
Most of the general public have only now begun to learn about the existence and understand what a 3D printer is. Due to the fact that 3D printing is

now receive printed tissue cells instead of the previous methods of having to surgically graft their skin. Although the previous method is highly
successful and leads to functioning skin cells after the healing process is over, "The grafts... ideally come from locations that are not ordinarily
visible, such as the buttocks or upper thighs, because the donor sites will not be normal in appearance after they heal" (Skin Grafts for Burn

Application Of The Additive Manufacturing
INTRODUCTION Additive manufacturing has been developing since 19841. Charles hull invented it. In additive manufacturing 3 dimensional
products are built by staking materials layer by layer. It is also known as 3D printing. The scope of technology is sky rocketed with the intervention of
the fourth–dimension time, which is 4D printing technology. The interesting feature of 4D printing is it can transform from 1D to 3D shape, 1D
surface to 3D shape, or can morph from 3D form to another form. In other words, the products can change and adapt to the external stimuli. This is a
recent advancement in technology additive manufacturing combined concepts of shape memory materials and biomimetic composite In a TED
conference Sky Tibbits head of MIT self–assembly lab, he presented, how 4D printed object will perform self–assemblies over time period. He
demonstrated this process by using 3D printed multi–layer material. The multi–layer material was strands of standard plastics which has property of

3d Printing Is Changing The World
3D printing is changing the world we live in today. Business Insider calls 3D printing "The Next Industrial Revolution" (Rega). Imagine having the
capability of producing any product you want at your fingertips within minutes; it is now possible because of 3D printing. Simply put, 3D printing is
the process of creating real objects by "printing" chosen substances layer by layer until the desired product is made, therefore 3D printing is sometimes
referred to as additive manufacturing. There are endless possibilities with 3D printing from the medical field, to manufacturing, automobiles, to
airplanes, and also personal use. 3D printed objects are going to be an integrated part of everyday life. Contrary to what you may think, 3D printing is
not new. Its roots stem from inkjet printer concepts. However, instead of printing with ink, it prints with material. The concept of 3D printing has
been around for about 30 years. It inventor Chuck Hull discovered it in 1983. One day, Hull became frustrated at how long it would take for small
plastic parts that he needed for his job to be manufactured and decided to fix this problem. At the time he was working for a business that made
plastic veneers for tables and other furniture items. They would put this liquid like substance on objects and then dry it using Ultra Violet (UV) light.
Hull got the great idea to take this liquid substance and the UV light and create 3D images by layering the liquid. Originally he called this

Innovation Represented By My Artifact: 3D Printing
The innovation represented by my artifact is additive manufacturing, more commonly known as 3D printing. 3D printing is the process of turning
digital designs into 3D objects in real life. This is done by slicing the digital design into layers and recreating those layers with molten filaments.
Filaments come in different variety and size. Some including ABS plastic, metal alloys, skin tissues. 3D printing was created in 1983 by Chuck Hull.
Hull patented his technology as stereolithography. The technology was patented, so at the time 3D printing was a innovation few know and use.In the
year 3D printers can be categorized in two sections, consumer printers and industrial printers. Consumer printers are mostly desktop size, customized
for personal uses. Industrial printers are customized for factorial use. They can print larger designs along with a broader range of filaments than
consumer printers.

3d printing takes time, the more material required to create something, the more time it takes up. Designers use as less material as possible in their
designs to decrease the wait time, unintentionally reducing producing waste too. structures reduce waste up to 80%. In manufacturing industries,
3D printed parts are estimated to save waste by 30%. 3D printing can also help conserve the environment. One major example of this is the coral
reefs. Coral reefs are an important part of the marine ecosystems but they are in decline due to climate change and ocean acidification. Corals can be
replicated with 3D printing. In 2014, the world's first 3D printed coral reef was sunk. The reef was printed with sandstone to resemble actual reefs. It
has a low carbon footprint and does not produce greenhouse gases until concrete. These artificial reefs not only can provide marine lifes with a home

You pack everything that you think you need for deployment. You conduct your demand analysis that leads you to believe that what you packed is
just what you need. Every deployment you had been on before confirms that those are the assets that will lead you to mission success. However, this
deployment is different and just about everything you brought is not required and to source it from else where will take too long. In the near future the
most viable solution will be to print it. As 3D printing now formally known as Additive Manufacturing (AM) evolves, the possibility of have everything
you need at your fingertips will have a profound impact on your operational readiness. Implementation of additive manufacturing at the Intermediate
level (I Level) of a Marine Aviation Logistics Squadron, will drastically reduce the acquisition and production lead–times associated with low demand
items, items that are impacted with obsolescence, and drastically reduce cost and footprint of conventional logistic models. One advantage of AM is
dramatically reducing acquisition and production lead–time associated with low demand items. Currently, Defense Logistics Agency's (DLA) demand
forecasting is predicated on either previous demand history or flight hours which will determine how much to buy and how much to stock. This
formula is great for the high demand and major end items as they are more predictable with continuous monitoring for any changes in pattern. Utilizing

Especially for large volume the production speed in additive manufacturing does not allow an economical usageof this technology. Therefore, the
inclusion of additive processes into the production chain of conventional manufacturing is part of the recent research, which concludes hybrid
processes. The additive manufacturing is a sequenced method the combined processes should be repeatable in sequences as well. The most obvious
combination is the additive manufacturing process with a subtractive process liNe milling. Both technologies require a 5Yaxis machine for a full three

Crystal Structures and Additive Manufacturing Report
Introduction
Crystal structures refers to the certain ordered pattern of stacking atoms, and it can repeat and stack to form the material (Wikipedia, Crystal structure).
We are studying how atoms are arranged within a unit cell. It is crucial that different crystal structure can determine the properties of materials. By
analyzing the crystal structure, we can create the materials with certain properties. The additive manufacturing, also called 3–D printing, means that we
can 'print' parts or actual structure just by repeating and stacking small piece of material layer by layer to create the material we want (3dprinting.com,
what is 3d printing). We studied this to know how to create crystal structure in .stl file and how 3D printer creates 3D models. This is important
because 3D printing can create actual structure instead of assembling parts, which is more convenient than the old ways.
Crystal Structures
The atomic difference between amorphous glass and conventional metal is the length of the range order. The conventional metal has long range order
of unit cell, whereas the amorphous glass do not. Therefore, metals have certain melting point, but amorphous do not have. The short range order
means that the unit cells forms short periodic arrays, so amorphous are short range order. In contrast, the long range order contains long arrays, and it
always forms larger grains (Rempel, "Relation between"). Therefore, long range

3d Printing In Archaeology
Will 3D printing revolutionize our understanding of archaeology? 3D printing is a captivating advancement of technology that has profuse uses.
Different from all the previous manufacturing methods, 3D printing generates a product in an additive mode to form an intricate three dimensional
object, and therefore has the ability to produce the most complicated irregular object. This unique characteristic deems it highly impactful for
archaeology, where the structures of historical human forms and the tools they used are often very complicated and unique, and there are currently no
simple means to reproduce and study them. Clearly, 3D printing and scanning has many useful benefits to archaeology, and there is definitely room for
improvement. ... Show more content on Helpwriting.net ...
First of all, plastic is the main material in most printers, and this material biodegrades EXTREMELY slowly: 450 to 1,000 years! This would
create a serious environmental problem if objects were discarded and thrown into landfills, especially because technology is bound to become
cheaper, and this will lead to more people owning personal 3D printers. Another worrying aspect is the fact that guns and other weapons can be 3D
printed with ease, though it would take quite a long time. Already some people own their own 3D printer, and the numbers are sure to rise in the
following decades. It will be quite difficult to keep tabs on the printers, causing a dangerous issue. Of course, if the trouble increases, it is always
possible for the government to set a law stating that only individuals with a license can own 3D printers. The difficulties don't end there, though.
Consider this dilemma. If every single human in the world owned a personal 3D printer and scanner, what would happen to businesses? If there was
a product someone took interest in, they could simply print it at home without spending any money! In archaeology, complications arise as well. In
order to print larger artifacts, you need a substantially larger 3D printer. If you were to replicate a house, a relatively sizable printer would be
required, along with a large stock of plastic and a printer larger than a house. This also means that the cost of

Digital Printing And Its Effect On Building Houses
Your next house could be made out of concrete, by a 3D printer, in 20 hours. 3D printing, also known as Additive Manufacturing, is revolutionizing the
way we build houses. This topic is extremely important, as it could save us time and money. While it could be expensive to build the printers and
research the idea, this new idea of this construction method is worth the preliminary investment because 3D printing saves money on building
materials, labor, and building 3D printed homes releases half the pollution of a normal construction site. Currently, the commercially available 3D
printers we have are only able to print in plastic. Some custom printers are able to print in concrete, such as the Concrete Printer by Andrey Rudenko,
or the printers owned by the company Win Sun, based in Shanghai. But no printer is capable of printing an entire house, so far the printers are only
able to print out the pieces. Each piece is assembled into the house at the construction site.
If we had a strong enough and large enough printer that could print entire houses, many communities that suffer from homelessness problems could
set up some kind of funding to be able to provide housing for many people, and homelessness would no longer be a problem the United States has to
bear any longer. The 3D printers you can buy on the internet are around $500 for a basic printer, to $4500 for a professional home printer. A printer of
significant magnitude and size able to print in concrete is estimated

3d Printing And Its Effect On The Entire Supply Chain Forever
Introduction
3D printing is a new technology that could potentially change the entire supply chain forever. It is rapidly evolving and gaining a place in many
companies. According to a survey performed by the Business Insider as seen in figure 1, 60 percent of firms are either actively using or are evaluating
the potential of using 3D printing (Wile). There are an infinite number of uses for 3D printing that come along with advantages and disadvantages.
The 3D Printing Process
3D printing, also known as additive manufacturing, is the process of successively layering material to form a 3D object ("What is 3D"). This process
begins with the formation of an idea. This object can be anything from a hand, to a vehicle component. Using computer aided design (CAD), the
user can transform an idea into a computerized 3D model. However, if the item already exists, the operator can use a 3D scanner to make a digital
copy of the object and shorten the process ("What is 3D"). After the user has the digital 3D model, the computer horizontally divides the virtual object
into hundreds or thousands of "slices," as seen in figure 2. The printer then starts producing the object, layer by layer. The printer head moves
side–to–side and up and down as it deposits layers of material ("How 3D Printing"). As each successive layer is printed, they are blended so that the
human eye can hardly see the individual layers, if at all ("What is 3D"). The mixing process is crucial for the visual and

How Technology Has Changed The World And How Things Are Done
3–D printing is an emerging technology, that if properly done, has the potential to change the world and how things are done. Although there have been
many advancements over the years, with further research and development this technology can become less expensive, easier to make, and bring us
things like household products and printed pizza. The Oxford dictionary defines 3–D printing as "a process for making a physical object from a
three–dimensional digital model, typically by laying down many successive thin layers of a material" (Definition of 3D printing in English).
3–D printing has existed for decades and has morphed from a simplistic technology into a complex one. It all started in 1984, when Charles Hull came
up with the idea of a 3–D printer. The online book Where are you from? states that, "It first started with The Charles Hull's invention of stereo
lithography, which gave engineers and designers the ability to create 3–D models of their designs by printing them". The printers use lasers and
materials like plastics and polymers, that scan back and forth making objects that were previously designed on a computer and then uploaded onto the
printer.
Now deciding what type of 3–D printer to buy can be the hardest thing. In certain cases, 3D printers are better bought either fully–assembled or
self–assembled. A lot of places go ahead and buy a printer that is fully assembled and that can work as soon as they take it out of the box. Although
some people feel that

that technological developments have pushed out human society into a state where technology has become interwoven into our daily lives. 3D printing
technologies also have the potential to change the political order. It is accepted that technologies have political elements and 3D printing may underline
the relationship between technology and economic and political order. Capitalist order was mainly built upon machines. So could the generalization of

Ict And Its Impact On The Society
Innovation in ICT and its impact on the society has been astounding. It is considered to be "crucial for economic activity" (Jorgenson and Vu, 2007) as
it not only "increases productivity and boost economic growth," (Jorgenson et al, 2008) but "generates complementary innovations that improve
economies ' total factor productivity." (Ceccobelli et al, 2012)
3D printing is where a "three–dimensional object is created by laying down successive layers of material that adhere to one another, creating a
three–dimensional output." (Kurt and Colegrove, 2012) It has the ability to "turn digital files created on a CAD or CAM program into physical
objects." (Hoffman, 2015) MakerBot Replicator is a typical example of a product that uses 3D printing. (Figure 1)
The Replicator uses 1.75mm polylactic acid (PLA) filament. Various colors are available, meaning that lots of flexibility is given as to the final look
of the product that's printed.
As its software, MakerBot Desktop software is used. This allows individuals to "save files in a personal Library that you've created, printed, or want to
print; find new objects in the Thingiverse to print; and access instructional and troubleshooting videos." (Hoffman, 2015) In other words, it's software
that enables you to manage and print objects.
Aside from the main software, individuals can also "print from a computer over a USB, Ethernet, or Wi–Fi connection, as well as over Wi–Fi from an
iOS or Android phone or tablet with the MakerBot

Three Dimensional Printing Is An Additive Manufacturing...
THREE DIMENSIONAL PRINTING TECHNOLOGY
INTRODUCTION
Three Dimensional Printing or 3D Printing is an additive manufacturing process of creating a wide variety of products covering diverse sectors of
manufacturing. It is called an additive process because of the fact that material is added in this process of manufacturing instead of machining it out
from a base substance.
The basic principle behind the working of a 3D Printer is to convert a digital file into a three–dimensional model by adding material layer by layer to
obtain the entire object. It is a sequential process of depositing material in successive layers on the basis of the digital model prepared by CAD Software.
But just preparing the 3D Model is not the end of the manufacturing process. To enhance the existing properties of the object further and to attain some
specific properties, the object needs to undergo some other operations as sintering (in case of ceramics to obtain the required strength and high
temperature stability).
STEPS INVOLVED
1. 3D Model Design
The first step of this process is to design the model of the object of desire using Computer Aided Design (CAD) Software. The model should be the
exact replica of the object to be created by 3D Printing. In the 3D Digital Model itself we need to slice the object into very thin layers of about
0.03–0.1mm thickness. These layers will serve as the guidelines for the printer to print the object.
2. Selection of Material
The next step will be to feed the

A Report On Additive Manufacturing
Additive Manufacturing(AM) is a manufacturing technology that creates objects rapidly with the help of Computer Aided Design (CAD) files.
Different from traditional manufacturing method, additive manufactured models are usually stacked out by a serial of planer slices which are
produced by processing wanted CAD designs with mathematical code.
Stereolithography, commonly known as SLA, is one of the most applied forms of AM technology. Stereolithography researches were first appeared in
1970s, then in 1986 Chuck Hull patterned a technique capable of stacking planer cross–sectional geometries, in the direction of bottom to top, into a
complete physical model. The unique material in Hull's pattern was ultraviolet sensitive photopolymer. This technology was named and coined as the
term "Stereolithography". In the same year, Hull also founded 3D system Inc., currently known as the first and biggest 3D printing enterprise.
After decades of development, stereolithography now can be described as an Additive Manufacturing process that hardening or curing photopolymer
resin layer by layer into actual objects. The light source, usually using ultraviolet light, provides essential energy for stimulating and maintaining
photo–polymerization reaction in which smaller molecules bond and form cross–linking polymer molecular chains. The energy source of
photo–polymerization reaction can be a laser beam or mask projection patterns. The laser beam moving trajectories or mask projection

3d Printing And Its Effects On The Economy

in popularity of the new technology. Because of this, a new market of 3D printing will begin to grow and emerge very rapidly due to curiosity which
makes this new technology a huge effecting factor on the economy.3D printing is the process of additive manufacturing which creates objects by using
a nozzle with a ABS plastic filament, melting the plastic, and layering the plastic in the appropriate locations in order to create an object. Though it is
a relatively simple process, it takes a lot of calibration and fine tuning and the end result can be breathtaking. Because of the rapid growth and
popularity of this new technology, many different people, commercial manufactures to household families, are curious to get their hands on a 3D
printer. Since the technology is bound to change the way people and businesses handle daily tasks, 3D printing may have some negative economic
effects such as hurting international trade with other countries and harmful health effects due to the chemicals used in the printing process. Though
these are harmful to the economy, there are even more positive effects such as helping provide clean water for 3rd world countries, producing
