Your task is to watch the video, and then write a page or so to argue for or against the possibility of 3D printing and the likelihood that the copies will work just as well as the originals. You should refer to (or better, USE) the epistemic concepts we have been talking about in lessons in your arguments. Some possibilities to consider include (but is certainly not limited to) how certain you are, how strong their/your justification is, do you really know or are you guessing, what further information would you need to be more certain, etc.

I know that 3D printing is possible. This is because I have seen a video about it and eliminated remote possibilities such as that the video is just a scam, seeing as it is from a reliable source, an authoritative source, the National Geographic Channel. The justification provided of a wrench being produced in a video seems to be sufficient. I believe that 3D printing is only feasible for certain applications. For example, 3D printing has been proven to be feasible for opaque objects with moving parts such as wrenches through the video. For the copies to work just as well as the originals, the properties of the hardened powder must be exactly the same as the material of the originals, as materials with different properties work differently. I believe that 3D printing is only feasible where the property of the materials needed is exactly the same as that for the solidified powder, or when the difference in property of the powder from the original does not affect the use of the tool. The powder, when bound, is hard, according to the video, can be hardened with resin, can be modified, but it appears that the material, though editable, with current 3D printers appears to be only of one type of material. I am merely guessing, however, all the models shown seem to be made of a single material. Even the object designed to show

...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.

...3D Printing: New Technology Solving World Problems Berenthia Smith Lecturer: Dr. Raymond Wells Due Date: 23rd January, 2016 College of the Bahamas Abstract In the 21st century, it is inherent to say that technology is new. The word technology is symbolic of the word new in and of itself. Technology is created every day. The human race continues to grapple with the issues of today’s world and how technology can be used to solve world problems. The concept of 3D printing is discussed in relation to cost, customization and diversity. It is visible how 3D printing plays a role in solving world problems. According to White and Bruton’s definition of technology, it is defined as the way people use learning and knowledge to assist progress (2011). In other words, when people and businesses find new ways to use their experiences to solve problems, it is known as technology. Today, there are a number of technologies that are popular; whether it be because they are trendy or because they are rather useful. One of these technologies is Three Dimensional Printing (3D printing). Hoffman’s article defines it as the use of a machine to print objects through a layering process. The machine is controlled by data files usually generated from Computer Aided Drafting (CAD) or Computer Aided Manufacturing (CAM) software. The differences between 3D printing and traditional production is that the objects created the traditional way, once completed, will sometimes have to be further altered...

...Montella 3D Printing in the Medical Field And in Education Jared Berrett 12/1/13 How do 3D printers work? There were a lot of choices to choose from since 3D printing as expanded over the years. As I was looking into 3D printing to see what a good topic would be to expand on, I came across 3D printing in the dental field and in education. 3D printing in the medical field has expanded a whole lot. We can now make bones and some tissue. 3D printing can be used for several things, but I decided to specifically talk about 3d printing in the dental field and in education. First I’m going to talk about and explain why 3d printing is going to be useful in schooling and in the future schooling. Then I’m going to talk and explain some of the bad effects people see on 3d printing. Then I’m going to explain how it is useful in the medical field and how the doctors can improve on using this tool that is now out there. Then lastly I’m going to explain why 3d printing is such a good new technology that we all need to learn how to use and use one for good. How do 3D printers work? They work like inkjet printers, but instead of ink they use plastic. The machine uses ABS plastic, the same as LEGOS. So the first thing is 3d printing in school. Kids these days are going to have a lot of opportunity to learn in the field and be able to have hands on with their learning and such. I read in an article that said “Project difficulty can be tailored to a Student’s abilities and interests, so 3D printing...

3d Printing

...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.

...on the rise is three dimensional printing. Three dimensional printers are machines that can take a shapefile or design created in a computer-aided design software, CAD, and produce the custom designed image into a working test product. Three dimensional printing has taken manufacturing to a new level due to the ease of producing prototypes. Companies have harnessed this technology and used it to produce actual size prototypes that can be physically held and interpreted before producing. These prototypes can also benefit by being a “dummy” for creating injection molds. Indeed this technological advance is a great hype and improvement in the world of production saving time and money in the long run; however, the question is raised, can this epidemic be harnessed by everyday users in their home? There are both pros and cons to the use of three dimensional printers that need to be addressed before the decision can be made of whether this advancement is sensible or not. Nick Allen from Gizmodo.com is very strong on his article expressing the cons to the issue. On the other hand, Christopher Barnatt, from his website Explainingthefuture.com, takes more of a liberal stand to the issue at hand. Three dimensional printer pose numerous negative effects to the world. While this technology may seem cool, new, and intuitive, the idea of owning such printer at home may actually be a far cry from reality. The printers with the capability of printing in three dimensions use a mass...

3d Printing

...3-D printing sounds futuristic, something that’s destine to succeed in our future. It is a small evolutionary step from spraying ink 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, 3-D printing really is bringing in a new era. 3-D printing gives the business an opportunity to expand their sources into this new era. Using a 3-D printer I will not only impact the business on a national scale but it will mainly target businesses locally and eventually localize them. Although this might increase prices for items but it will eliminate costs like shipping, this could also mean parts and items could be made on site, as they are needed. However if this carries out it will shrink the size of Chinas work force, as it is the workshop for the world. Experts agree that rising Chinese labor costs and improving, technology will gradually cause significant manufacturing activity to return to their own countries. One of the most promising research activities is boiprinting. This type of 3-D printing is working to develop and refine various boimanufacturing required for organ tissue fabrication. This means that a glucose-sensitive pancreatic organ can be grown in a lab then transplanted anywhere inside the body to regulate the glucose level of blood. If something like this can go ahead and succeed it will open up the world of 3-D printing and...

3d Printing Opportunities

...In your view, is 3D printing the most important opportunity facing manufacturers in the UK? 3D printing is the process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material. In my view 3d printing is currently the most important opportunity facing UK manufacturers however, there are also many other exciting opportunities becoming available to the UK manufacturing industry. Previously 3D printing was simply an idea that had a lot of issues to resolve but now the machines have become more reliable and can be used to produce various products from a number of different materials including but not limited to plastic, metals, glass, concrete and chocolate. 3D printing is ideal for products that need low quantities producing or where high customisation is required (mass customization). Now, instead of using the technology to make prototypes it can be used to produce the real thing quicker and probably cheaper than ever before. This significant cost reduction should help to reduce unit costs and improve competitiveness as well as reducing manufacturing waste by up to 90%, and with our strong heritage in engineering and materials science, the UK is definitely in the right place to take advantage of 3D printing which will not only encourage investment in to our economy from abroad but it should also revolutionise the way manufacturing is conducted in the UK making Britain a template for a changing...

Through further research and development, this technology has the potential to save lives through medical uses, equip military members with necessary tools, reduce manufacturing costs, and help the environment. 4) INTRODUCTION h) Today, 3D printers have evolved to make a variety of objects using a laser or extruder (the material output part of the printer, best described as a futuristic hot glue gun) that move along an X, Y and Z axis to build an object in three dimensions, layer by layer, sometimes only microns thick at a time, depending on the desired resolution of the object. This method eliminates a lot of wasted materials. For example, in ship manufacturing any leftover powdered substrate can be immediately used on another project, alleviating the need for injection molding, setup costs, cutting, sanding, drilling and having scraps of material left over, as is common with traditional manufacturing methods. (Hart, 2012) i) The history of this technology must first begin by briefly describing the history of all printing methods. Without those first basic principles...

Amazon and 3d Printing

...3d printing is no longer a theory or a concept. It has been available to industrial manufactures for the last few year but now as technology is advancing at its usual frightening pace the first home consumer printers are becoming available and like the original printers they are rapidly moving on from their slow, expensive and cumbersome beginnings . The Makerbot replicator 2 is an example of a 3d printer available to the consumer retailing for approx $2000. 3d printing relies on additive manufacturing which allows objects to be built layer by layer only using the exact amount of material needed reducing waste and of course allowing for more complicated designs to be printed in full form. Users can design a 3d model in computer software programs such as CAD and print off the design by inputting materials such as plastic or mouldable metal and other forms of materials that allow the object to be printed in full form. The technology has already being used to print off a replacement jaw for an 83 year old woman out of titanium powder and many believe the technology will greatly enhance medical services . Furthermore ,the technology has endless less obvious benefits such as printing off replacement parts and printing off designs that are impossible to be handcrafted but entirely possible when designed and produce on CAD or similar software. Many are predicting 3d technology to be a game changer to the entire world. Amazon is a global leader in e-commerce offering a wide range...
