3D Printing: Impacting Our Future

3D Printing, also known as additive manufacturing, is a technology that has been around for a while already, but in recent years technological advances have made it significantly cheaper and more attainable for many people. You can print 3D images designed on a computer with a 3D modeling program, or you can scan an object with a 3D scanner to be replicated. To print the model of the digital file the program hypothetically slices the image into a bunch of different horizontal layers. There are a few technologies used for 3D printing, the most widespread technologies are Selective Laser Sintering (SLS), and Fused Deposition Modeling (FDM). In the SLS method a high powered laser melts and fuses tiny particles of metal, plastic, ceramic, or glass powder until the desired shape is achieved. In the FDM process a continuous feed of metal or plastic wire is fed through a heated nozzle melting the material briefly while it forms the object.

One major impact that 3D printing could impact the future is bio-printing, or the replication of human bodily tissue through 3D printing. If you’re in need of a new kidney, instead of waiting for a compatible donor, the doctor, in theory, would be able to go to his computer load up kidney.obj press ctrl + p and within minutes begin the operation. There are many more ways the technology could help the medical fields of study, such as reproducing human bones or blood vessels. Artificial limbs could be made more affordable. the cheapest artificial limbs used today are a generic one size fits all application, which could prove to be highly uncomfortable, with 3D printing they could better fit them to the wearer without having to break their bank account for comfort.

Another way 3D printing could impact our world is eliminate the need for shipping and stocking replacement parts. The parts could range from anything from your car to your stove and everything in between. Going to Auto-zone to buy a universal joint and having them inform you that the closest one is at their Biloxi warehouse and wouldn’t arrive until Thursday would be a thing of the past. All that they would have to do is load up the file for the replacement joint, fill the printer with the correct material, and within a few minutes you would have it. Also eliminating shipping and stocking should also make the price of parts drop.

3D printing could also help the pollution problems of today, if products are being printed locally on an on demand basis, many major manufacturing plants emitting pollutants into the atmosphere would have little choice but to shut down. I’m sure 3D printing will never replace major production factories completely. Maybe those factories will decide that it is more cost effective, environmentally friendly, and take less manpower to deploy large scale 3D printing than to continue the operations that they have currently going.
Surely 3D printing on a large scale will also emit pollutants but I can’t see it emitting near as much.

3D printing could be a great thing for humanity. Of course you can’t just put a kidney shaped piece of plastic in your body and expect your body to accept it. In 2010 biotechnologists started experimenting with using 3D printing with inkjet techniques using layers of living cells and a gel medium to build 3D objects. Also there would be a lot of lost jobs if shipping and stocking became obsolete. Not to mention the production jobs that would be lost. 3D printing sounds like it’s going be great for humanity, but I guess we will have to wait and see where it takes us, I for one and hopeful for it.

...Unit 1 Research Paper 1: Paradigm Shift Introduction In the past, virtual reality technology was thought of by many as a gimmick, and the hope for it to become a mainstream technology was discarded as products did not work as how the public envisioned. However, the proper technology is now available to make virtual reality just that: a reality. The entertainment industry is on the verge of a monumental paradigm shift that will completely transform the way these entertainment mediums are experienced. The typical experience of video games is one with a controller with joysticks that are used to control where the playable character is looking along with a monitor or television screen in front of the player. Today, this scenario is so typical that the detachment between the player and what is happening on the screen is something considered to be normal in the experience. In the next couple years however, this detachment will be largely erased as working virtual reality headsets become available to consumers across the world. Summary of Key Findings One notable product in the field of virtual reality technology is the Oculus Rift. What makes this product and others like it different from the virtual reality fad that permeated the entertainment industry a few decades ago? The Rift uses 360 degree low latency head tracking, an integral part of the complete virtual experience. In previous VR headsets, the latency, or delay, between a player’s head movement and the visual representation...

Gs1140 Unit 1 Research Paper 1 Electrolysis and Cars

...Electrolysis and Cars Roy Howe ITT-Tech Abstract In an article on the Stanford University website I found an article about something that I think has a tremendous amount of potential. It is the process of electrolysis, the splitting of water into hydrogen and oxygen. The man problem with this process has been that you always had to put more into the process then you gained from it. I believe that has changed with this breakthrough that is written about in this article. Scientist at Stanford University have developed a low-cost, emissions free device that uses ordinary AAA batteries. Electrolysis and Cars Introduction Automakers have long considered the hydrogen fuel cell a promising alternative to the gasoline engine. Fuel cell technology is essentially water splitting in reverse. A fuel cell combines stored hydrogen gas with oxygen from the air to produce electricity, which powers the car. The only byproduct is water – unlike gasoline combustion, which emits carbon dioxide, a greenhouse gas. (SHWARTZ, 2014) The implications of this are vast, one of the areas that this will change in the next 20 years is that we will have a clean zero emissions way of producing gases that can be burn within automobiles. The Technology The proton exchange membrane electrolyzer also works in exactly the same way, by decomposing water with an electric current. The distinctive feature is a proton-permeable polymer membrane. An external voltage is applied to its electrodes, which...

...Unit 2 Research Paper 1: Global Warming During the last fifty years, two environmental issues have received significant attention: global warming and the hole in the ozone layer. As scientists have investigated these two environmental phenomena some have made some effort to show that these two effects are somehow related. In this research paper I will further elaborate on their relationship. Ozone high in the atmosphere absorbs ultraviolet radiation from the sun, thereby protecting living organisms below from this dangerous radiation. The term ‘ozone hole’ refers to recent depletion of this protective layer over Earth's Polar Regions. People, plants, and animals living under the ozone hole are harmed by the solar radiation now reaching the Earth's surface—where it causes health problems from eye damage to skin cancer. In the 1980s, scientists discovered that the ozone layer was thinning in the lower stratosphere, with particularly dramatic ozone loss known as the ozone hole in the Antarctic springtime. This is caused by increasing concentrations of ozone-depleting chemicals in the stratosphere that come from spray cans and refrigerants. These long-lived chlorofluorocarbons or CFCs (chemical compounds with chlorine and/or fluorine attached to carbon) remain in the atmosphere for decades to over a century depending on the CFC. At the poles CFCs attach to ice particles. When the sun comes out again in the polar spring, the ice particles melt, releasing the ozone-depleting molecules...

...Zombie Virus or Rabies-Flu Hybrid? Could a highly improbable genetic tweak cause a mutant virus? Hollywood would sure like us to believe it, or else they would lose at the box office. Though humans once dead can’t rise from the grave, it is possible that certain viruses can cause violent aggressive behavior, one such virus is Rabies, which could cause some zombie-like traits. Rabies is a viral disease and it causes the central nervous system to become afflicted with horrible symptoms, causing a human to act like a stark raving mad lunatic. Once infected, humans do not immediately show signs of the disease. Actually, the first signs of rabies, such as confusion, hallucinations, anxiety, and paralysis- could lay dormant in the body and not typically appear for a week up to a year. Once symptoms do appear, if left untreated, could be fatal within a week. Now take the influenza virus’ ability to spread rapidly through the air, and combine it with rabies. Could this combination possibly cause a zombie apocalypse? I think if this were to happen, gun sales would sky rocket. Can you picture it? The caption would read, “Now open, Zombie Season, how many can you get?” Rabies though is no laughing matter. Viruses can exchange pieces of genetic code, but they have to be related. It’s scientifically unheard of when two different viruses like rabies and influenza merge, because they are too different. Viruses don’t mix and match, they interchange only with their own gene family. Nature...

...GS1140 Problem Solving Theory Unit 1 Research Paper 1: Paradigm Shift Daniel Yerger Page 1 Robotics Technology The idea of robots came about in 1495 by Leonardo Di Vinci who designed the first humanoid robot. The first computer-controlled robotic arm was designed by George Devol and Joe Engleberger in 1954 this led to the development of the first industrial robot in 1961. In 1977 Star Wars the movie creates the strongest image for the human future with robots like R2D2 and C3PO in the 1960s it inspired a generation of researchers in the robotic technology field. In 1989 a walking robot name Genghis was developed by the mobile robots group at MIT and was known for the way it walks called the Genghis gait. It is predicted by the Japanese Mitsubishi research Institute that each household would on a robot by 2020. Robots are mechanical devices that does some type of work or has a purpose that people would normally do, some robots are totally controlled by an onboard computer system and sensors, and some robots are controlled by people. Cybernetics is also a type of robotic technology device that can replace limbs, some of these devices are controlled by the nerves of the limb that was severed in some way. In 20 years we should be able to replace limbs that will look part of the body and be controlled as if it was the original. Industrial robots are used in it in a vast number of factories the well-known ones are in the auto manufacturing industry. A lot of the products...

...GS1140 Unit 1: Research Paper 1: Paradigm Shift Introduction: In this research paper I will be talking about cell phone technology and how I think it might change the way we live in 20 years. I will be talking about how cell phones will be used in the medical field by doctors, how we will use them for entertainment purposes, and how we will use them for connecting to our family in everyday life. I will also talk about what might prevent this technology from advancing and become obsolete. Cell phones have come a long way since the first call was made April 3, 1973 by Martin Cooper. The first cell phones were big and bulky, so big that they weighed a little more than 2lbs. They were so big that some were carried in small brief cases, and others looked like a brick with an antenna. The first cell phones were something that the very elite or very wealthy had, because they were very expensive going for about $2500-$3000. The first cell phones only had about 30-45 minutes of talk time and took about 10-12 hours to charge the battery. The old cells phones did one thing and that was to make phone calls very expensive call. They didn’t even store any number/contacts in them. Today it seems that everybody has a cell phone. Today there are more than 5 billion cell phones in use today. The phones today come in just about every GS1140 color and in a bunch of different styles. They are nowhere as expensive as they once were. Today’s cell phones have more memory, computing...

The problem is: how to waste less time waiting at the DMV? There are many possible solutions, but the one I choose to test is: by making all DMV services available online, with only a limited number of physical DMV locations and services available. Modern technology maximizes operations while reducing associated costs. (Hanington, 2012, p.43). The first step in order to test if this solution is appropriate is to look at cost viability. How cost efficient and practical will it be to conduct operations entirely online? Some costs, such as staffing and building utilities will go down, but other costs like web developers and advanced software will occur. I think the data will be in favor of online business. According to the Financial Planning Info Guide, service usage and profitability is higher for online businesses, while the costs for content and production, distribution and service is lower for online businesses than traditional ones (2013). Another step is to test if going completely online is an appropriate solution is to look at the market for it. Surveys and interviews can determine how many DMV patrons are internet savvy, or if the majority of DMV patrons have a preference for online or in-person service....

The previous owners landscaped part of the backyard, but she would like help in landscaping the rest of it. Andy has the potential to be a great landscaper, but isn’t very good at math and will need Jourdan’s help before he can get started. Jourdan’s yard is 200 feet long, and its width is 75% of its length. The portion of her yard that does not need to be landscaped is along the shortest part of the yard and is 10% of the width of that part of the yard. Jourdan would like to put in grass, but does not want it to take up more than 1/25 of the space in her yard (space is in ft2). What is the largest area the grass can take up? If Jourdan’s grass takes up that much space and each grass piece 4ft wide, how long are they? Jourdan would like to add some brick to her patio. If each of those bricks is 6 inches long 3 inches wide. She only needs to cover 15 square feet, how many bricks does she need? We have discovered that the length of her yard is 150 feet. She will not need to landscape 15 square feet. 120 square feet of yard space will be covered in grass. Each piece of that grass is 30 feet in length.

...GS1140 Unit 2 Research Paper 1: Experiment You are a supervisor in an office setting and you have noticed tension growing amongst your staff members. The problems have become apparent not only to other employees but to the customers as well. For fear of damaging the business’ reputation and in turn this affecting sales, it is necessary for you to investigate the situation further and to restore a pleasant work environment. To begin you must establish a plan of action. First identify the main source of the problem. Interview all parties knowledgeable of the situation. Be sure to take note of comments and suggestions given by staff members during your one-on-one interviews. Often those close to the situation have great insight on how to end such conflicts. Once you have conducted your investigation determine the level of priority this situation deserves. Ask yourself if this is low priority, meaning something that can possibly work itself out or is it a situation that needs prompt attention and an immediate solution implemented. Consider if the problem may be solved amongst staff or perhaps a third-party intervention may be necessary. Remember, you have to work with the individuals, so it might be necessary to involve a third-party. When you have planned your course of action, it is time to bring everyone together and inform them of your solution. Remember to remain calm, communicate effectively, be fair and use good management skills. Once you have given set instructions...

The procedure-in which a knee or a hip is replaced with an artificial implant-is highly invasive, and many patients delay said surgery for as long as they can. A doctor by the name of Jennifer Elisseeff , a biomedical engineer at Johns Hopkins University, hopes to change that with a simple and quick procedure that does away with surgery entirely. Dr. Elisseeff and her colleagues have developed a way to inject joints with specially designed mixtures of polymers, cells, and growth stimulators that solidify and form healthy tissue. This form of technology can eliminate the need for many expensive and dangerous surgeries. Surgeries involving muscle development, the cardio vascular system, and even limb repair after a traumatic incident. This form of technology can improve our health care system dramatically and open new windows of opportunity for new forms of medicine. Even the possibility for new cures for diseases that we currently fight every day such as cancer and possibly even HIV, eliminating the need for long and expensive treatments. As well as repairing worn or damaged tissue, this form of engineering can also be used in the future for growing new organs or limbs to replace old damaged or missing ones.

The more the population grows, the more congested our roads get with more vehicles. Besides leaving hours before traffic starts to avoid traffic jams there has to be another solution. Some solutions include: employee parking cash-out, tolls for single use carpool lanes, and tolls during high peak hours on freeways. An employee cash-out can reduce the amount of vehicles on the road by giving an incentive not to drive (Bullokk, 2011). Companies would give a certain amount each month to the employee who participates in the program. Through data mining, the decrease in the demand of parking can be obtained. The information needed to gather this would be: the number off employees in the program, the financial incentive amount, and the amount of time the incentives were given at separate but equal intervals (Bullock, 2011). A decrease in cars on the road would limit the amount of traffic on the road and also free up precious parking space. Tolls for single use carpool lanes will also benefit in decreasing traffic. The carpool lane is mostly always free of traffic during rush hours which is good for carpoolers, but also counter intuitive. The carpool lane turns into a wasted lane if people are not taking advantage of carpooling. Sensors can be placed in cars to automatically charge the fare for...

Some people get depressed more than others due to serious amounts of stress. I have experienced a certain amount of stress that has led me to be depressed and has led me to think about doing unimaginable things. A friend of mine was depressed to the point of almost trying to commit suicide again. I however didn’t agree with his course of action so I talked to him and got him to relax. I told him there are plenty of solutions to keep yourself happy and to stay away from depression. My solutions consisted of hanging out with your friends, Playing games or watch your favorite shows or to have happy thoughts. If I ever get depressed I typically go straight to my friends. Having friends around helps because they do anything to make people happy. Talking to our friends makes us forget about the depression we go through and makes us think about others for a change. Thinking about others can lead to changes in action upon depression such as suicide. If you think about what your friends might go through if you die you most likely won’t commit to such course of action. You’ll choose to live on for them and start doing all you can to make yourself happy. Usually when I’m down in the blues ill tend to play some video games or watch anime.

.... Course GS1140 (Wed) ITT Tech 12/18/2013 Unit 1 Research Paper: Paradigm Shift Electric cars are technology currently in use today. Instead of using a commonly used gasoline engine the car is driven by an electric motor and is usually powered by battery. There are also hybrid cars which use a combination of electricity and gasoline. These are also starting to become popular. Some benefits of an electric car over gasoline cars are a quiet ride since it has less moving mechanical parts, environment friendly since it doesn’t put out harmful emissions and lowering dependence on foreign oil companies. One impact that will occur from electric cars is the loudness of cars. Because a car would be more quieter this could have two related impacts. This could affect road safety because drivers and more importantly pedestrians may have a harder time locating on coming vehicles since most people identify with sound quicker before sight. The second impact of having quieter cars is proximity of roads and highways. Since homes and residences usually avoid noisy highways having quieter cars could allow a change toward having more highways through residential areas. This could significantly affect building zones and regulations. The second and probably the most important impact would be the effect on the environment. Since gasoline engines put out harmful emissions there is no doubt electric cars would provide a cleaner healthier environment. This could have a long term effect...
