3D printing is making it easier and quicker to yield complex items with numerous moving pieces with elaborate designs, and it is affordable enough to have at home. Additive manufacturing is a category of manufacturing technology that contains 3D printing under its guidelines. Additive manufacturing is creating an article by adding a substance layer by layer to the item in which you are creating. Additive manufacturing has many aliases that you may have come across such as stereolithography, 3D layering and 3D printing. Just like how water drops layered make icicle like mineral deposits in caves, 3D printing does a similar process in which it add layer by layer of material to its base. In contrast, 3D printing is a more rapid process and shadows a programmed design provided by computer software. The computer directs the 3D printer to add each new layer at a precise cross section of the final object.
3D printing is built upon inkjet knowledge and was accessible for 2D printing since the 1960s. Nozzles in a 2D printer move back and forth dispensing a fluid. Conversely, instead of the nozzles moving the printing surface moves up and down as oppose to flat movements. Moreover, these printers don't use ink; they dispense thick waxes and plastic polymers, which solidify to form each new cross-section of the sturdy 3D object. 3D printing was modeled after the 2D printer generation which paved the way for this new exciting technology.
Binder printing is a major competitor and has a few advantages over direct 3D printing. For example, it has a tendency to to be quicker than direct printing because less material is applied through nozzles. Moreover, another advantage is that you can incorporate a wider variety of materials in the pro...

...eos on how to make them. First models were not full developed to what they are now. Some 3D printed guns that can perform just as well as a real gun. Having access to that type of information on the internet as the potential to do great harm. Now guns could be sold without serial numbers and have a high black market presence. Now everyone who has access to a 3D printer can print a gun in their own kitchen. This raised eyebrows and the government had it removed immediately from the internet when posted, but the gun’s design was on the internet for three days’ time. Which is enough for something to go viral and others copy the design and post it elsewhere. A few days afterwards the files had spread to various webpages where it has been downloaded well over 100,000 times. How can the government keep up with the threats? As of right now it is a game of cat and mouse.
...gun provided a convenient way for crime; people could get any dangerous weapons to endanger the safety of others. In the article, “At Least 9,900 People Have Died From Guns In The U.S. Since The Newtown Shooting: Slate”, Dominique Mosbergen pointed out that the number of mass shooting kept growing because of the lax gun control system. For example, 20 year old, Adam Lanza took several legal guns and went to Sandy Hook Elementary School after killing his mother. Besides that, he only spent five minutes to murder 20 children and six adult members of staff (Mosbergen). This school shooting in the United States completely shocked the whole world. At this point, many people had focused on the regulatory issues of guns. Mosbergen stated, “As the nation mourned in the wake of that unthinkable tragedy, many citizens and lawmakers raised their voices to demand” (Mosbergen).
Adam Clark Estes ' article, "3D Printed Guns are Only Getting Better and Scarier," is a new controversial twist in the ongoing gun control debate (Estes). It is an emotionally written blog for the creation of laws to hinder the making of 3D guns. Estes is a senior writer on Gizmodo, which is a website blog that focuses on technology in society. While Estes ' article is informative, it lacks a strong thesis, organization and structure. The first main point the author addresses in this blog is how easy guns are to manufacture with a 3D printer. He explains this by referencing the history of the first home-made gun printed by Cody Wilson, a twenty-five year old student from the University of Texas. Another main topic Estes elaborates on is how
With the massive rise in the quality, lower prices and availability 3d printers anybody anywhere in the world now has the ability to produce almost anything they like. Websites like https://www.thingiverse.com/ offer millions of models for almost anything someone needs to produce. Websites like https://www.upwork.com offer online consulting for 3d modelers that will design anything you need. Prior to the availability of 3d printers anything that was designed had to be manufactured at professional production facilities at huge costs relative to 3d printing it. 3d Printing lowers the barriers of entry into a market that was previously dominated by a few people because of the cost of prototyping.

Accompanying the high margin for human error, untrained citizens can use firearms in unlawful ways. According to a violence policy center analysis of news reports, CCW (carrying a concealed weapon) permit holders have killed at least 14 law enforcement officers and 622 private citizens since May 2007 (LCPGV 1). Most if not all of those deaths could have been avoided if there was no concealed carry law. People now need to be informed of the facts, and not some old false reasoning. What holds many people back from seeing the truth is the disadvantageous annotation that comes with change. Sure, this country was built on people who rose up and overthrew the unethical government with their own weapons, but that is not what is being threatened; the right of a militia and to own firearms is written in the second amendment. What does need to change, however, is the idea that the constitution is flawless and covers all things. Although the constitution does lay very stable ground rules for a country to be governed, laws are meant to change with new inventions and ideals. New models of more and more deadly firearms are created everyday, each being deadlier that the latter. What could be called into the question is not the banning of the weapon, but the banning of the deadliness of the weapon. New guns can be specially constructed to wound a
The controversy over assault rifles is one of the most problematic issues related to the contributions of gangs, drug traffickers, and most criminal activity. More often than not, criminals have access to the weapons of their choice more easily than it should be. Getting them from licensed dealers, black markets, and family members’ homes, the availability of these militia weapons has become to effortless to obtain. The rise of criminal activity is part of the reason more than one-third of high school students have easy access to a weapon or gun. “Four out of five guns brought to school are actually brought from their own homes” (Page par 2). This is one of the biggest problems when faced with where criminals get their guns. They either steal them from relative’s homes, ask to borrow them, or steal them from licensed sellers. There are a lot of ways people can get guns. People who should not be able to purchase a firearm are allowed to, and illegal transactions are also a huge issue with criminals getting their guns. For all these reasons that is why Government should require restricted gun ownership to protect society, prevent crime, and allow for recreational use.
Due to the alarmingly large number of public massacres, gun reform has yet again become a highly debated issue in America. In the past, laws were enacted that were meant to restrict ammunition and military classes of weapons from resale in the United States. Due to strong lobbying efforts of the National Rifle
Gun violence is one of the United States' most serious crime problems. The total cost of gun violence in the United States, including medical, criminal justice, and other government and private costs, is at least $6 to $12 billion a year (Cook, P. J. & Ludwig, J., 2000). The Bureau of Alcohol, Tobacco, Firearms and Explosives’ (ATF) mission is to track firearms. It reported that firearms sales have risen since 2005. According to the ATF Online Statistics website, in 2005, ATF processed 147,484 National Firearms Act forms.... ...
In present time, if we look closely around everything we visualize: the clothes we wear, the colors of the room in which we find ourselves, the traffic signs, the television etc., everything around us had a process in which made the picture the sign the logo, Film, video, That where Graphic designs, photography, printmaking, computer-aided design and digital art come into play. Printmaking is a mechanical method to reproduce texts and images on paper, cloth or other materials. In its classic form, it consists of applying an ink, usually oily, on metal pieces to transfer it to a paper by pressure. There is a couple of different technique when it comes to printmaking like relief, intaglio, lithography, and serigraphy which matrices included wood
People nowadays might get the impression that the 3D printing technology is a relatively new concept in our daily life. However, 3D printing technology is invented and utilized in many fields such as creating human organs in healthcare, building architectural models in engineering, even forming components that can be used in aeronautic fields long ago. Since Charles W. Hull has invented the 3D printing technology in the 1980s, scientists, engineers, and even normal people were and still are trying to discover more possibility of the usages and changes on this technology. Same as every invention of the new technology, with its undeniable beneficial effects, 3D printing also faces lots of limitations

4D printing offers the ability to make things that literally pull themselves together. The technology could also create objects that last longer than their 3D-printed counterparts and adapt to specific conditions on command. 4D printing is relay about using a 3d printer to print self requfingering programmable material. For example you have a non-living object that can change his shape and behavior over time kind like a robot but no microprocessors, in fact something that looks like a plastic. Skylar Tibet’s, the man who came up with whole idea has gone even fodder; he created a programmable sheet material. It look like a plastic, that in combination with the water it could change the shape in the cube. And the cube is just a beginning. It will be a million of shapes. It could be so useful, not just on the Earth but in the orbit as well. This idea could change the world, and living on it. Imagine you could just print your furniture. An...
Warfare is what led to the creation and manufacturing of firearms all over the world. Firearms made war less savage and protected soldiers in battle without them needing to even get close to their enemy. In today’s society, guns have reached far past being used in warfare, being used to murder, steal, and threaten. People are terrified now more than ever because of guns falling into the wrong hands. Although guns have many cons, they have many advantages to back them up in recent protests against them.
The topic I have selected for my essay will be on 3D printing in education, I chose this emerging technology because of my place of work and how 3D printing may be involved their within the next few years. This would require me to research how 3D printers work and how to operate them. I also believe that having 3D printers in schools will generate a new wave of creative children in the future. In this essay I will be showing how a 3D printer works and how the machines operate. I will be providing example on why I think 3D printing is important for education, as well as showing what hurdles 3D printing has to overcome in regards to Intellectual property rights and the legality of what you can and cannot print. In this essay I am going to point out the advantages of what a 3D printer can achieve for the future and how it can possibly shape the way we educate our children.
