...3D Printing Technology To anyone who hasn’t seen it demonstrated, 3-D printing sounds space-age, like the meals that turn up in the Jetson’s oven at the touch of a keypad. The technology is quite straightforward and is a small evolutionary step from spraying toner on paper to putting down layers of something more substantial (such as plastic resin) until the layers add up to an object. And yet, by enabling a machine to produce objects of any shape, on the spot and as needed, 3-D printing really is leading in a new era. (Barnatt, 2013) The use of 3D printing is quickly becoming a very affordable option for producing physical objects. The term ‘‘3D printing’’ covers a number of closely related technologies, all of which produce a 3-dimensional physical object from a computer model by building it up in successive layers. These technologies were developed primarily for use in rapid prototyping for industrial design; they allow a designer to convert a computer model of a prototype into a physical object quickly in comparison to most previously available technologies. (Massis, 2013) The 3D printers use standard inkjet printing technology to create parts layer-by-layer by depositing a liquid binder onto thin layers of powder. Instead of feeding paper under the print heads like a 2D printer, a 3D printer moves the print heads over a bed of powder upon which it prints the cross-sectional data sent from the 3D printer software. The 3d printing system requires...

...The Third Party Doctrine: An Unreasonable Method for Determining Unreasonable Fourth Amendment Searches in an Ever Advancing Technological World The Fourth Amendment provides, “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” Viewed through the specific lens of criminal procedure, there is a long list of jurisprudence that sought to determine the most efficient manner to balance two very important, but competing, interests: the public’s interest in preserving its privacy rights and expectations, and the government’s interest in its ability to investigate and subsequently prosecute criminals. However, the methods and rules previously established have yet to be fully tested in our ever-evolving world of technological advances. This raises the question of whether certain well-established rules, specifically the Third-Party Doctrine, are ill-suited to address modern issues. As it has been applied since 1979, and in the absence of reevaluation, the Third-Party Doctrine is likely to impede, severely, on the privacies guaranteed by the Fourth Amendment. In order to fully understand the gravity of this predicament, the evolution of Fourth Amendment analysis must also be understood. In 1949, the Court...

...3D printing economic questions and considerations 3D printing economic questions and considerations Definition Three dimensional printing refers to a procedure that employs the formation of solid three dimensional objects that can take the form of any shape desired based on the designs of a digital model. In order to achieve a three dimensional print output, one is required to utilize the additive procedure that involves the use of successive material layers that are laid in arrangement such that different shapes are displayed. There have been considerations of three dimensional printing as technique of traditional machining that greatly relies on material removal through use of methods such as drilling and cutting which is part of the subtractive procedure. I) History of 3D printing technology The historical development and context of 3D printing technology Three dimensional printing has existed for over thirty years, long before it was popularized. From the 1980s this technology utilized the inclusion of a layer fused in powdered material with the combination of a laser as well as dispersion of plastic that was melted through a nozzle system and resin that was photo-cursed. Nonetheless, three dimensional printers remained expense ice and where characterized as being sluggish with inefficiencies as the industry redeveloped at a slow pace during that era (Lanzetta & Sachs, 2003). The rapid popularization and growth of three dimensional printing begun only after the start...

...What is 3D printing? 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. How does 3D printing work? 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 such as time-of-flight, structured / modulated light, volumetric scanning and many more. 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 integrated 3d scanners. Digitizing 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 30 USD DIY devices anyone can make at home. Processes and technologies Not all 3D printers use the same technology. There are several ways to print and...

...3D STREAMING TECHNOLOGY AND LIMITATIONS 3D films are not a new technology, but only recently have movies been brought into our homes thanks to the high capacity of Blu-Ray discs and because of new televisions that feature high refresh rates which show films at double the frame rate required for our eyes to distinguish motion. A 3D movie is really two entire movies shown at the same time, one that your left eye sees, and one for your right eye. Special glasses are required to switch between the two in a way that your brain perceives as three-dimensional. Because of this, twice as much data is needed for a 3D movie compared to a 2D one, which presents certain issues when trying to send this data over a medium such as the Internet. Thankfully, several technologies are emerging that will make this possible in the near future and that we believe Blockbuster is well positioned to take advantage of in order to offer 3D content streaming to their customers. The biggest factor of sending a movie over the Internet is the amount and type of compression that is used. It would be impossible to send a fully uncompressed high definition movie directly to your home, whether or not it is 3D, because the amount of data is staggering. In order to make the files smaller and able to be sent in small pieces, companies like Netflix use compression formats such as MPEG or AVI which use special technologies that result in smaller files. This involves limiting the bit depth for colors in a way...

...Technology vs. Guns: The Unseen Side Effect Gun control is a topic that is at the tip of every politicians tongue in today’s society. With mass shooting seemingly on the rise it is no wonder why many are in an almost frantic mental state to find the cure for this pandemic. Any sane person can tell you that it is a great idea to keep firearms out of the hands of criminals and the mentally unstable, but the question remains of how? With the aid of computers and a mass network of online information, many pro gun control advocates are pushing for laws that require more stringent background checks with the use of these online databases. But what if these same technologies that may help us regulate the ownership of firearms, also lead to a more easily access to firearms in the future? And will more laws for gun ownership make the country a safer place? First and foremost, do gun control laws work? According to the statistics it would seem to be so. But in order to grasp the issue fully, it is imperative to first look at the existing gun control laws that are in effect. There are numerous laws both at the federal and the state level restricting the sale, purchase and use of guns. Although they may vary from state to state there are basic federal laws that are in place nationwide. These laws include that no person convicted of a crime can own a gun and also that a person must be 21 or older to purchase a handgun. One of the laws having the most profound impact recently...

...Morals and Ethics A major issue that has risen from the personal use of 3D printing is the ability to produce weapons. This issue along with others brings the concern for the morals and ethical behavior that will come along with 3D printing. Different countries will utilize the machine in different ways, hospital usage, producing food, environmental, at risk for jobs, pirating, and the good will all need to be evaluated to determine the potential threats or success of 3D printing. Many countries have found a use for the 3D printer; China is using it for bio printing and Canada is using it as an education tool for children. “The Makerbot at the Lunenburg library is one of sixteen 3D printers distributed by the Nova Scotia government in 2013 to rural and urban locations around the province” (Barrett).The library has found a way to inspire children with more than just reading and utilizing computers. Barrett’s simple explanation of a 3D printer is; “the box is a Makerbot Replicator, a desktop 3D printer. It is reading instructions from a digital card and “printing" layers of corn-based, petroleum-free plastic to produce a usable 3D object”. Facilitating an educational use for 3D printers will give younger generations an introduction to future innovations. This allows the machine uses beyond a profit engineering tool.

...ABSTRACT 3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. The 3D printing concept of custom manufacturing is exciting to nearly everyone. This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts. Now, you can create a complete model in a single process using 3D printing. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern. 3D Printers are machines that produce physical 3D models from digital data by printing layer by layer. It can make physical models of objects either designed with a CAD program or scanned with a 3D Scanner. It is used in a variety of industries including jewellery, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education and consumer products.

Additive manufacturing's earliest applications have been on the toolroom end of the manufacturing spectrum. For example, rapid prototyping was one of the earliest additive variants, and its mission was to reduce the lead time and cost of developing prototypes of new parts and devices, which was earlier only done with subtractive toolroom methods (typically slowly and expensively).[19] However, as the years go by and technology continually advances and disseminates into the business world, additive methods are moving ever further into the production end of manufacturing—sometimes even in ways that the pioneers of the techniques didn't foresee.[19] Parts that formerly...
