Future Availability of 3D Printers and Its Effects
Almost every houshold has a 2D printer. This paper will talk about the 3D printer, and how it has saved lives, made lives easier, allowed people
create amazing objects with the printer, made production faster and cheaper, and how the printer will revolutionize the world as we know it. The 3D
printer goes back to 1976, around the time that the Inkjet printer was invinted. Charles Hull changed everything by making the first commercial 3D
printer. He offered it for sale through his company 3D Sytems in 1986. The way Charles's printer worked was via a technology called stereolithography.
Stereolithography is a technique that uses a laser to solidify an ultraviolet–sensitive polymer material. The technology remained unkown from the
general public until the second decade of the 21st century. Manufactures used 3D printers secretly to make prototypes of products for 20 years. In 1999
the first lab made organ was implanted into patients that were going through urinary bladder augmentation, using 3D artificial scaffold layerd with their
own cells. This technology was made by scientists at the Wake Forest Institute for Regenerative Medicine. The technology opended the door to
developing other strategies for engineering organs, including printing them, Since they are made from the patients cells, there is little risk of failure. In
2002 scientists engineered a minature working kidney that is able to filter blood abd produce diluted urine in an animal. This led them to the

Price is a key component to making this technology accessible to companies and people everywhere. If the technology is too costly then industries
cannot be expected to use the product and make profit. It wasn't until 2009 that 3D printers became available to the public (3D Printing History). As the
technology progressed the prices continued to lower and made the 3D printer more available to the average consumer. According to Hongkait you can
purchase small affordable 3D printers starting at 100 dollars and under 1,000 dollars (Voo).
Present applications and development
3D printers have the ability to do more than just make prototypes for a design company. There are medical, automotive, food, electronic, and many
more uses. The 3D printer can create weapons, prosthetics and implants, pieces of vehicles, toys and plenty of other amazing things (What is 3D
printing?). One of the most amazing things about this technology is its ability to create something, as you need it. It can cut down on time and get rid
of any shipping previously needed.
The automotive Industry was one of the first industries to adopt the 3D printer. A good example of this is the well–known company automotive
company Audi. Audi has yet to use the 3D printer in their production lines but they are getting close to that reality. Recently Audi created an entire car
using just a 3D printer and it ran smoothly (Koslow 2015, November 13). What automotive companies

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

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

NASA launched a 3D Printing machine towards the International Space Station to develop parts in zero gravity, which will aid in future
innovations in Astronomy. This new technology produced by NASA is one of the best upheavals that have occurred in that field. The Oak Ridge
National Laboratory has built a complete car body through 3D Printing. The car took less than twenty hours to print. Although the car model is not
permitted for use and its sole purpose is to be a model for upcoming inventions, this will significantly decrease the cost of cars in the future when
we will be able to drive 3D printed vehicles. In 2014, the first 3D printed skull as successfully implanted in a woman. Doctors in the Netherlands
reported that they have for the first time successfully replaced most of a human skull with a 3D printed plastic one and saved someone's life in the
process. The surgery lasted 23 long hours and took place at the University Medical Center Utrecht. The patient suffered from severe headaches due to
a thickening of her skull. Due to this condition, she slowly lost her vision and her motor coordination was suffering. Usually in brain surgery the
doctors temporarily remove part of the skull to reduce pressure, but later on put it back or replace by an artificial implant. In this groundbreaking case,
doctors inserted an entire plastic skill that was manufactured with the help of an Australian medical device company that

The Medical And Dental Industry For 3d Printing
3D Printing is a unique kind of printing system, which takes a 3D image file and creates a physical 3D image. As I mentioned before 3D files are
generated from what is called a .stl file, which is a compressed triangular meshed surface. "These .stl files were originally intended for a rapid
prototyping process called Stereolithography, and in the beginning were generated by CAD programs; however, because MRI and CT's are surface
scans, they too can generate a .stl file. These .stl files have become a world standard for exchanging 3D mesh type objects between programs"
(McNeel, Sep. 2015, par. 3). Since MRI's and CT's can be scanned and converted into stl files it has paved the way into many different aspects of the
medical and dental industry for 3D printing. When I say the medical and dental industry I am talking about many different avenues within those
industries.
Let us first take a look at the dental industry and the latest developments and how they will impact our lives. Have you ever considered braces for
fixing yours or your loved ones teeth? Remember what looked like metal tracks in someone's mouth to correct their teeth? Well, now they are using a
plastic form called invisalign instead of metal. These are all created with 3D Printing and they work just as well, and don't tear up one's gums like the
railroad track braces. The German–based company EnvisionTEC has helped to innovate many premium 3D printing materials and now they are

the following Equation: Error = r/sin (Оё/2) – r Where r = radius of the nozzle and Оё = angle of cross sectional geometry. The Following figure is
drawn between the intended angle made by nozzle in digress to the error in geometry. From the graph it gives clear idea that when the geometrical
angles are larger in any geometry the errors are less. This illustrates as we go to the larger angles the error is going to be reduced.the three lines in

The Ethics Of 3D Printing
Current medicine up has typically depended on the human body as its main model in the creation of organs for transplants and teaching methods. Up
until recently X–Rays and cadavers have served as primary reference points for the structure of bones and were used as universal models for almost
every human. However, now with the introduction of the 3D printer in the medical field, the possibilities and advancements are growing and the
options are becoming endless. Using scientific research on current studies in the medical field will demonstrate what 3D printing is, how 3D printing is
revolutionizing surgical procedures and teaching methods, and what actions should be taken to ethically use this invention.

Although Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) collect images that are three–dimensional, they are viewed on a
two–dimensional screen which limits the amount of interaction doctors and surgeons can have. The benefits that using a 3D printer would have to
print three–dimensional models of the skull and brain would be that it would allow doctors to physically visualize surgical techniques and options. For
procedures such as intracranial electrode implants being able to physically see the curvatures and convulsions would make the planning for the
operation more precise and the operation would go smoother. Two neurologists from Harvard and a Boston hospital tested the possibility of using a 3D
printer to create three–dimensional models of the skull and brain. Using MRI and CT scans they successfully printed over nineteen brain hemispheres
from 7 patients. The cost to print these hemispheres was between $1–5 each. The results showed that using a 3D printer to create the brain models
proved to be a cost effective process and could be used for surgical planning, patient education, clinical research, and teaching

Pediatric Physical Therapy

In pediatric physical therapy, it is common to see a child with cerebral palsy, muscular dystrophy or another physical deformity utilizing an ankle–foot
orthosis, which the child will inevitably outgrow in a short period of time. As one doctor so adequately states, "if there was a Murphy's Law of
pediatric orthotics, it would be that all growth spurts occur immediately after receiving a new orthosis, if one did not occur between the casting and the
fitting" (source) What if there was a way to quickly and inexpensively manufacture an orthosis to meet the changing needs of these young patients?
This is only one example in the field of physical rehabilitation where medical rapid prototyping could prove an enormous benefit. ... Show more content

Because of its increasing use in other areas of the medical field, physical therapists will likely have an amplified exposure to some form of 3D
printed technology, especially in relation to the bioprinting of skin cells, joints, and cartilage. In the past year, Wake Forest Institute for Regenerative
Medicine pioneered efforts utilizing the technology for skin grafting. A portable scanner is used to estimate the depth of a burn, which is important in
determining the types of "ink", or cells, to be printed, and then prints new skin cells directly onto a burn victim in a very precise manner (source). Due
to an increasing number of people receiving hip and knees arthroplasties, 3D printing is also being explored as a means of producing a more
personalized fitting implant that lasts equally long or longer than traditionally made artificial joints. One research group is exploring the use of calcium
polyphosphate bone "ink" coated in the patient's own (stem cell) tissue as a means to producing more natural, longer–lasting replacements. Another
group has developed a high strength fully–porous titanium material with tunable mechanical properties in order to reduce the amount of bone loss seen
in solid joint replacements (source). Bioprinting is also changing how surgeons might soon approach cartilaginous repairs. Traditionally, meniscal tears
are treated by cutting off sharp parts and smoothing the remainder of the cartilage; transplants are rarely used due to tissue compatibility issues and
stock implants are difficult to fit to a diverse range of patients. As of mid–2016, Active Implants has been recruiting for a second round of human trials
to determine the ability of its 3D–printed medical polymer–made meniscal implants to withstand high compressive loads over time frame of greater
than 10 years. In separate clinical trials, scientists at Cornell and Columbia Universities are testing 3D

Designing A 3d Modeling Software
Once you have a 3D model the next step is to prepare it in order to make it 3D printable. Preparing a 3D model to be 3D printed is called slicing.
Slicing is dividing a 3D model into hundreds or thousands of horizontal layers. This is done with software. It can sometimes be done within a 3D
modeling software application. Certain 3D printers require a certain slicing tool. Once the 3D modelTo begin 3D printing you first have to make a
virtual design of the object that you want to create. The virtual design is a CAD (Computer Aided Design) file. A CAD file is created using a3D
modeling application or with a 3D scanner. A 3D scanner is used to make a 3D digital copy of an object.
3D scanners: Microsoft and Google have recently created hardware that can perform 3D scanning. An example of this is Microsoft's Kinect. Soon
digitizing real objects into 3D models will become much easier. Smartphones may even have integrated 3D scanners.
3D modeling software: 3D modeling software comes in many forms. There's industrial grade software that costs thousands of dollars a year, or there's
a free open source software, like Blender.
is sliced, it is ready to be sent to the 3D printer. This can be done via USB, SD, or wifi, depending on the brand and type of 3D printer you have. When
a file is uploaded in a 3D printer, the object is 3D printed layer by layer. The 3D printer reads every slice and creates a three dimensional object.

Power Of Personal Production By 3d Printing
Power of Personal ProductionImagine that you could design a three–dimensional object as quickly as it would take to decide on material and computer
design: this idea is what created the technology of 3D printing. From the conception of 3D printing in 1984, to the first stem cell transplant, 3D
printing has evolved from a sci–fi like idea to a realistic addition in individual consumer lifestyles. Now instead of relying on large manufactures to
produce a special or specific good, the consumer has the power of this production in their own home, creating individuality through cost productive
methods of production. "When you produce something yourself instead of purchasing it, that changes your relationship to it," says Chelsea Schelly,
assistant professor of social sciences, of 3D printing. "You are empowered by it." This empowerment is about to spur on a new industrial revolution in
the manufacturing and distribution cycle. In essence, this printing revolution will encourage the individual to "create, innovate, and fabricate" their own
personal design. In order to obtain a clear understanding of the increasingly popular scientific technology of 3D printing, it is necessary to research the
history, current discoveries, and applications; however, maybe the most important topics to be discussed are the future directions, possible hazards, and
intentions of this industry.
Although printing has been around for centuries, the beginnings of three dimensional printing can be

The Advantages Of 3D Bioprinting
A review of the capabilities of 3D Bioprinting and it's medical uses.
3D printing was invented by Charles Hull in the early 1980s according to C. Lee Ventola, (2014). 3D printing was formally known
asstereolithography (A.B. AlAli, M.F. Griffin, and P.E. Butler, 2015) Hull made it possible to print various complicated plastic objects by using a file
on the computer. This file gives information regarding the object's shape, colour, texture, and thickness. The 3D printer is similar to a normalinkjet
printer, but instead a 3D model is printed. "Three dimensional printing is a manufacturing method in which objects are made by fusing or depositing
materials – such as plastics, metal, ceramics, powders, or even living cells – in layers to produce a 3D object" (C. Lee Ventola, 2014). 3D bioprinting is
a branch of the 3D printing which uses living cells to produce living organs. This essay states that 3D bioprinting of prothestics, organs and tissue will
cause donors to become obsolete.

(A.B. AlAli, M.F. Griffin, and P.E. Butler, 2015). The main advantage of the usage of 3D Bioprinting in medical procedures is that all the models can
be modified at the patient's desire. This means that Bioprinting may change a lot in the ongoing years considering organ transplantation.For example,
the usage of body's own stem cells to create new organs that can be transplanted. This means that rejection of the printed donor organ is minimal since
own cells were used to produce the organ (C. Lee Ventola,

Scan, Modify, 3D Print: Revolutionizing the AFO
Problem Statement
Last summer, I started an internship with Shriners Hospital for Children in their Motion Analysis Lab. During my internship there, I realized that
many children could not afford to wait the three months necessary for standard ankle braces. In addition, many poorer families struggle to afford such
expensive devices. My goal for this invention is to develop a feasible and medically accepted system in which a 3D scan of the patient's foot will be
manipulated on the computer to create a custom, 3D–printed brace. This innovative new process, combining the new technologies of 3D scanning and
3D printing, will result in an orthotic that can be produced quickly and inexpensively.
Research & Background
The Ankle
The ankle is an incredibly complex component of the skeletomuscular system. The ankle–foot complex must provide both stability and mobility. It is
responsible for providing a stable base of support for the body (stability), but must be flexible enough to absorb the body's weight during gait (mobility).
The talocrural joint, or ankle joint, is formed by the articulation of the talus with the tibia and fibula. The talus's shape allows 3 planes of motion:
dorsiflexion/plantarflexion, inversion/eversion, and pronation/supination. The purpose of an AFO (Ankle–Foot Orthotic) is to stabilize the talocrural
joint.
Orthoses
Orthoses (plural form of "orthotic") refer to a broad group of medical devices that support, immobilize, or treat muscles, joints or skeletal

The Concept Of Interpolation In An Animation System
To compute a new image from a new perspective, in the first instance we project the two images among which the user is currently on the 3D model
retrieved using the triangulation. The two meshes will overlap on a part of the model. The part which does not overlap, is then projected on the image
plane, which is, in our system, the plane $mathcal{P}$, the billboard. However, if the ray between the image plane and the 3D point is interrupted by
another section of the 3D model, that point is not shown in the image plane. This is an improvement of the textit{margins} described in section

The last component to be produced is a player for the content produced with our system. The content could be played inside the game engine, but
providing a standalone player has several advantages. The first advantage is the extensibility of the system. We are planning to prepare a plug–in for
several game engines, starting with Unity3D, but expanding, in the future, for instance to the Unreal Engine. Having an animation software and a
media player both independent from the plug–in allow us to develop it for every engine we need without the obligation to create a specific player for
each of them. Moreover, it is more appropriate for the users who will enjoy the content, who should not download and install an entire game engine
just to access it. In this section it will be illustrated the work plan for the project. At the end of the section are presented Gantt Diagrams with a visual
explanation of the planned work. During the third year, the first four months, between October 2017 and January 2018, will be dedicated to the
improvement of the game engine plug–in based on the triangulation, explained in section ref{sec:fw–improving–2.5D}. We plan to publish a paper
about this work. The four next months, between February and May, will be committed to develop the key technologies required for the animation
software, while in the following three months the focus will be on its user interface. This last task is particularly important, since the user interface must

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

3d Printing And Its Effects On The World Of Manufacturing
What if there was a machine that could make anything, in any combination of materials with infinite complexity, enabling users to manufacture goods
instantly at home? There would no longer be a need to go to a store or order a product online, saving people time and money. Fortunately, this
technology was invented 33 years ago and is known as 3D printing (Reichental). It is a reality today to create, 3D scan, or download 3D blueprints for
any physical object and manufacture them affordably in the home. With such technology, it is possible for anyone to produce high quality products
without having to buy them. This revolutionary technology is proving to be a game changer in the world of manufacturing, but it is causing many to
question the ethics of hyper–localized manufacturing and the ability for anyone to make anything. 3D printers are generating controversy surrounding
the ownership of designs, copyright laws, patent infringement, democratized counterfeiting, and illegal possession. 3D printing is ushering in a new
industrial age, but is challenging the current US patent system and compromising intellectual property rights, requiring reform to support next
generation design and manufacturing systems. 3D printing, also known as additive manufacturing is the process of making three dimensional objects
by depositing a material layer by layer. It was invented by Chuck Hull in 1983 and was called Stereolithography because of the layer by layer
production process

Three Dimentional Printing
3–D Printing
Albert Einstein once said: "Anyone who has never made a mistake has never tried anything new." Mankind is the most advance being on planet earth,
since the beginning of our time we have been pushing the boundary of the impossible and redefining the very rule of reality itself. Things we use to
see in cartoons and images in science fiction books are now becoming reality, so real that some of those futuristic technology are now part of our
everyday lives, and this is only the beginning of the technological revolution.
This century most unreal and controversial innovation is the 3–D printer; most people see 3 dimensional printing as way to make the world a better
place. But like everything in the this world where there is good there is also evil, and with this technology in hand some other people see an
opportunity to abuse the system and take advantage of the freedom to create whatever they can possibly think of to make the world worst than it
already is. So is it true that some things are best left untampered...?

Stephanie Crawford says SLA Printers work by a focused beam of UV rays on the surface of the object to be recreated. The CAD designed object
is filled with what 's called resin (photopolymer). When the light hits the resin, the liquid hardens to form a high resolution 3D model of the object
that you designed. Hull, a few years later co found 3D Systems Corporation, one of the first companies to sell a high end 3D printer and still is one of
the leading companies with this technology today. Charles Hull's first RP system, the SLA–1, was revealed in 1987 and quickly followed ongoing
testing until this system was sold in 1988. As always after new technology is discovered, there is always new competition, in 1987, Carl Deckard,
who at the time was working for University of Texas, filed a patent in the US for the Selective Laser Sintering (SLS). SLS method is somewhat similar
to stereolithography (SLA) but instead of using liquid resin, you can use powdered material in the instead. SLS made it possible to use a variety of
materials ceramics, nylon, aluminum, glass and steel or silver. In 1989 another new Printing process was invented by Scott Crump, he too co found
a leading company today Stratasys Inc. Scotts process was called Fused Deposition Modelling (FDM). This process is what is widely used by
beginners in 3D printing do to its easy refillable and cheap material. FDM works by melted thermoplastic materials joined together in

Makerbot Extruder Case Study
Makerbot extruder
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?

3D Printing Technological Advancement? I will be talking about whether or not we as a society should use the new "hot" product; the 3D Printer.
Overall I am for using the 3D printer. However there are ways the 3D printer is not a great item to use. The first printer dates back to the year 200 in
ancient China, back then it was called "woodblock printing." However the use of printing did not become popular until the 1440's when the printing
press came out. 3D printing or Stereolithography is fairly recently working, but the original technology for 3D printing was created by Charles W.
Hull in 1984. The reason why 3D printing is an issue is because it has beneficial and disadvantageous properties, and is becoming more prominent in
our society. There are both benefits and disadvantages of the 3D printer. As for benefits there are: bio–manufacturing, low cost of manufacturing, quick
production, and less waste. On the other though the disadvantages are: Guns, drugs, safety, and criminal uses. When it comes to disadvantages some
of these are atrocious. Not that long after the 3D printer came out some people tried making guns with the 3D printer, which is highly unsafe in the
wrong hands. If we can create human organs, why can't the 3D printer make drugs? Also are the plates we make with the 3D printer safe to eat off of?
Another thing to think about is the criminal uses, most recently some criminals in Texas printed an ATM scanner and put it on the sides of ATM's to

Advantages And Disadvantages Of 3d Printing
Introduction
We live in a time where technology is improved and advanced every single day. The health care environment is no exception. The technology used for
health care is constantly being refined and advanced in hopes to allow even better and more efficient care. One of these technological advancements
that could revolutionize health care is 3D printing. Benefits 3D printing could provide include construction of prosthetic limbs as well as anatomical
models aimed at determining patients' needs and many more (Ventola, 2014). However, there are also disadvantages of this technology and one of the
main disadvantages is the security issues it presents. There are both advantages and disadvantages of 3D printing but there is no denying the promise of
this technology and the potential impact it could have.
History
3D printing is a technology that was invented in the early 1980s by a man named Charles Hull (Ventola, 2014). Since its creation, 3D printing has
branched into many different aspects of the world and is being utilized in fields like the automotive industry, medicine and is even being used for
everyday purposes. Later on, Charles Hull founded a company called 3D Systems which developed the first ever 3D printer. In 1988, Hull and his
company 3D Systems, put forth the first commercially available 3D printer. From this point on, 3D printing would be advanced and evolved to the
point where it would have the opportunity to create a revolutionary impact on the world we

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

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

Advantages And Disadvantages Of 3d Printers
Introduction Paragraph: 3D printers have came a long way since their early days,They are used in so many ways today that help society and have
pushed the cutting edge of technology by a staggering amount. In this article I will be talking about how they've done that and provide some additional
information.
What Are 3D Printers??? At this point you have probably heard about 3D printers, but you may want to know more about them. To start off, I'll talk
about the genius mind behind this innovative machine.
The first official ВЁ3D printerВЁ was created by Charles W. Hull in 1983. Although, the first patent forstereolithography(a 3D printing technique) was
sent in by a Japanese engineer named Dr. Hideo Kodama, but the patent was rejected. Hull was born in 1939, he grew up in clifton colorado. He
found his love for science and engineering in high school and took that passion to college to get a bachelors degree in engineering physics.
Moving on, the first 3D printer was invented 1983, It was a lot like the printers today just a lot slower and clunkier. The main difference from now
and '83 is that printers use a different technique, they used to use something called stereolithography. Stereolithography is similar to the method we
use now (which is Computer Aided Design or CAD), it takes liquid plastic and turns it into structures, the only problem with this is that it requires a
very specific machine and it was very complicated to use. Although 3D printers were first invented in 1983 they didn't become mainstream until the
early 2000s. This was mainly due to the price and just overall how hard they were to use or even acquire. So as you can see it was very impractical to
use these machines back then, They were big, expensive and not very efficient.
What are they use for??? Before the 2000Вґs, 3D printers weren't used for much, they were in an experimental stage, but after that they started to gain
publicity. More resources went into making them better. After they started to get popular, they were more viable to buy and big industries started to
use them. Now they probably have hundreds of uses but there is only a handful of important uses. More recently people have started to make food with
them, This

Additive manufacturing, usually mentioned as 3D printing, has the potential to greatly accelerate innovation, reduces supply chains, reduces materials
and energy usage, and lower the waste.
Originally developed at ... Show more content on Helpwriting.net ...
By definition 3D printing is a very versatile and fast process accommodating geometry of varying complexity in many different applications, and
supporting number of of materials. This paper describes the core technology and its wide applications.
Additive manufacturing, usually referred as 3D printing, is a new method manufacturing products and parts from a digital model. Like an office
printer that puts 2D digital files on a sheet of paper, a 3D printer creates parts by depositing thin layers of material one after another ,only where
needed , using a digital blueprint till the whole part has been created.
Additive machines can now use metals, polymers, composites, or some other powders to "print" a variety of useful parts, layer by layer, as well as
complex structures that can't be manufactured by other processes.
By eliminating production steps and using very less material, 'additive' processes are able to lower waste and save over 500th of energy compared to
today's 'subtractive' manufacturing processes, and reduce material prices by up to ninetieth. the utilization of additive manufacturing can potentially

benefit a large number of industries as well as defense, automotive, biomedical, consumer products, and metals manufacturing and Even

In MakerBot's Thingiverse, a design community for discovering, making, and sharing 3D printable designs of shoes, jewelry, models of building,
tools, and other many goods are made (MakerBot's Thingiverse). Three dimensional printers have made a significant impact in prosthetics. Many
know that prosthetics are expensive and hard to come around. Many children in America and around the world with limb reductions can't afford to
have prosthetics. Most prosthetics would cost thousands of dollars, and with children growing every two or three months, parents aren't able to buy
one every three months. Most children would just wait until they grow up in order buy a prosthetic. If a prosthetic is damaged and needs to be
repaired, or a child is in need to get a new one, it will take the manufacturer's months to have it ready and delivered. Jen Owen, a volunteer at E–nable,
a volunteer based organization, says, "Using 3D Printing To Give The World A Helping Hand" (Owen). This organization helps, and gives robotic

Designing A 3d Design Of 3d Printing
3d printing is the process of three dimensional solid objects from a computer file. The following information is about 3D printing and the processes
that it takes to 3D print. There are many pro and cons to 3D printing that I will list below. In this paper I will also talk about what equipment it will
take to make a 3D print, But first we will talk about the steps to make a 3D design.
There are eight steps to print a 3D design. The first step is to start with making a virtual design of an object you want to create. The file that you
create the image from is called a (CAD) or Computer Aided Design file. This software may provide some hints to the structural integrity you can
expect in the finished product. It will also help you with specific data about certain materials to create virtual simulations of how the project will behave
under certain conditions.
The second step is called Conversion to STL. You will have to convert the CAD drawing, to the STL format. STL is an acronym for standard
tessellation language. Which is a file format developed for 3D Systems in 1987 for use by its stereolithography apparatus (SLA) machines. Most 3D
printers use STL files in addition to some proprietary file types such as, ZPR by Z corporation. Some of the types of printers include, Sterolithography
or (SLA), Digital Light Processing (DLP), Fused deposition modeling (FDM), Selective Laser Sintering (SLS), Selective laser melting (SLM),
Electronic Beam Melting (EBM), and Lamainatied

option of printing food in space is still under research.
8.Reduction in Plastic Waste:
Plastics are non–biodegradable and pose a major environmental threat. Fortunately, with plastic 3D printing, one can recycle plastics into filaments, as
it uses less energy to convert. One company has also developed a 3D printer that only works with recycled plastics.

The Pros And Cons Of 3D Printing
INDUSTRIAL REVOLUTION: ARMY PRODUCTION
INTRODUCTION
The Economist (2012) titled its article about 3D printing as 'The Third Industrial Revolution', implying that 3D technology has a potential to do so.
Will it really be happen? The answer remains to be seen, but considering the capabilities of 3D technology, it seems absolute. When we look back to
history, wheel, steam engine, and light bulb were all breakthroughs that shaped the way societies lived. In the 21th century,3D printing is the biggest
nominee for the title of new 'breakthrough' or 'game changer'. Taking into account the varieties of products that are the harvest of 3D printers, 3D
printing has already deserved that title and changed many traditional production rules. 3D printing or AM is used not only in civilian logistics but also
in military applications. Although it has some implications and drawbacks, 3D printing provides great opportunities for humanity, if used correctly.
On one hand, it can reduce costs and help us to gain more; on the other hand it can save the lives of people who are in need of urgent medical help.

The laser beam then traces the boundaries and fills in a two–dimensional cross section of the model, solidifying the resin wherever it touches. Once a
layer is completed, the platform descends a layer thickness, resin flows over the first layer, and the next layer is built. This process continues until
the model is completed. There is also process that uses extrusion tube that flows out melting plastics or other materials that will take shape in 3D
object and a process where glue or laser fuse together metal in a similar process to the stereolithography where by the plastic is replace by metal grinds.

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

How Digital Printing Is Revolutionize Our Modern Day Lives?
Where do you think the future of medicine will be in the next decade? With diseases and illnesses advancing, technology has been improving and
advanced innovative ways have been surfacing. Something that has modernized our way of life without even realizing it is a printer. Do you ever
foresee that printers could other than put ink on a piece of paper? Three–dimensional printing is revolutionizing our modern day lives in our own
selves as we speak. Although there are several types of 3D printing, one version that has caught the public's attention is 3D medical printing, or also
known as bio printing. This emerging technology will enable future 3D printers to produce synthetic human tissue, and eventually human organs and
transform how doctors and patients view medicine.
The use of 3D Printing dates back to 1980's when Charles Hull developed stereolithography (3D Printing). Hull received a BS in engineering and
physics from the University of Colorado in 1961. He was successful in integrating the computer for developing parts based on digital information.
3D printing is a printing process that allows digital data to create 3D objects. The creation of a 3D printed object is achieved using additive
processes. In an additive process, laying down successive layers of material until the entire object is created creates an object. Each of these layers

invented his machine in 1983, and he called it stereolithography and he later went on to co–found 3D system Corporation, which created the first 3D
printer. Many other companies have since then developed 3D printers for commercial applications.
3D printing or Additive Manufacturing is a process that takes digital input in the form of Computer Aided Design (CAD) model and creates solid,
three–dimensional parts through an additive, layer by layer process. It can also be defined as a manufacturing process by which objects are created
by fusing or depositing materials such as plastic, metal, living cells in layers to create a 3D item.
3D printers work like the inkjet printers but does not use ink, rather 3D printers deposit Materials in layers to create a physical object from a digital file.

Many people have one foot that is larger than the other or may be wider than the other and finding a pair of shoes that fit both feet is extremely rare.
And to make things even more difficult when buying shoes, the shoe sizing system is limited to the length of a person's feet without taking into
account how wide the feet are. With 3D printing all of these problems will be solved.
How Does it Work?
Rather than trying on numerous pairs of pre–manufactured shoes in standard sizes, a photograph is taken of your feet from various angles which is
downloaded into a computer to create an accurate 3D model of your feet. Information such as your weight, height, and daily activities are also
entered into the computer and combined with the details of your feet. A blueprint of the perfect shoes for your feet is then downloaded into the 3D
printer and a pair of shoes tailored exactly for your feet is printed. In some cases, this can be done in the store right in front of your eyes as is the case
at United Nude stores, or you can have them sent to you by companies such as Feetz.
3D printing shoes is not only used for fashion shoes but also has therapeutic applications. Makers of corrective orthotics are using 3D printing to create
custom–made orthotic shoes to alleviate foot pain and improve a patient's comfort.

Types of 3D Printers
Facts
There are two main types of 3D printing technologies for the consumer fused deposition modeling (FDM) and stereolithography apparatus (SLA).
FDM printers use a plastic filament that is melted and then pressed through an extruder in a layer upon layer fashion until an object immerges. FDM
printing is the more affordable of the two types as the overall cost associated with printer, filament, and printing accessories are cheaper. These prices
can start as low as $199 for a printer, $14 for filament, and accessories vary depending on accessory. Of the two types FDM has the most variety and
availability.
SLA printers use a vat of resin with a build plate inserted into it. A laser strikes the build plates to cure the resin. After a layer has be completed the
build plate moves away from the laser and the laser cures another layer of resin. This process continues until a 3D object is created. This type of
printer provides better prints and faster print times, but is far more expensive. Then entry level SLA printers start at $1099 and the resin comes in two
pack ranging from $119–$512.
Analysis
Given the two types of 3D printers the best printing type to center a business around would be the FDM style printer. These printers overall are simpler
in construction, cheaper to build and maintain, and easy to teach to students. The affordability of the printer and materials would make

3d Printing Or Additive Manufacturing
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object
is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is
created. Each of these layers can be seen as a thinly sliced horizontal cross– section of the eventual object. It all starts with making a virtual design of
the object you want to create. This virtual design is made in a CAD (Computer Aided Design) file using a 3D modeling program (for the creation of a
totally new object) or with the use of a 3D scanner (to copy an existing object). A 3D scanner makes a 3D digital copy of an object. 3D scanners use
different technologies to generate a 3d model from something that already exists. Recently, many IT companies like Microsoft and Google enabled
their hardware to perform 3D scanning, a great example is Microsoft's Kinect. This is a clear sign that future hand–held devices like smartphones will
have 3D scanners. To digitize real objects into 3d models will become as easy as taking a picture. Prices of 3D scanners range from very expensive
professional industrial devices to devices anyone can make at home. To prepare a digital file for printing, the 3D modeling software "slices" the final
model into hundreds or thousands of horizontal layers. When the sliced file is uploaded in a 3D printer, the object
