...Introduction Many products and parts made by the industry are produced by taking pieces of raw material and cutting away sections to create the desired part or by injecting material into a mold; however, a relatively new process called additive manufacturing is beginning to take hold where material is aggregated together rather than formed in a mold or cut away. Additive Manufacturing (AM) is defined as “the process of joining materials to make objects from 3D model data, usually layer up on layer ,as opposed to subtractive manufacturing methodologies, such as traditional machining” (ASTM Standard). The lack of tooling makes RM economically suitable for low and medium production volumes. Using additive techniques, an assembly of parts made...

...IMPACT OF 3D PRINTING ON ENGINEERING PRACTICE Name: Institution: Introduction 3D printing is the procedure of creating an objective material from a three-dimensional digital replica. Characteristically, this is done by laying down vast succeeding thin layers of a material (3-D printing: additive manufacturing, 2015). To print a 3D object, the manufacturer needs to employ a 3D computer-aided design. Consequently, this report paper shall attempt to look at the impact of 3D printing on engineering practice during the couple of years. Body Engineering practice is the technological activities that guarantee an organization or a company create products of the needed eminence as anticipated (ISPE Good Practice Guide: Good Engineering Practice, 2015). The impact of 3D printing on the medical application is considered to be developing quickly and is anticipated to change the health care. Medical uses of 3D, mutually definite as well as latent, can be arranged into broad alternate groups comprising of tissue along with organ fabrication. Other impacts of 3D printing engineering practice in the field of medicine include the formulation of modified prosthetics, anatomical structures as well as the use of implants in the human body. It is vital to acknowledge...

...GUO, Ming C. LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1]. It is also known as additive fabrication, additive processes, direct digital manufacturing, rapid prototyping, rapid manufacturing, layer manufacturing and solid freeform...

...| Consumer 3D Printing “3D printing has the potential to change everything” * Former Ship Engineer What is 3D Printing? The process of making a three-dimensional solid object of virtually any shape from a digital model is 3D printing. It is also known as Additive manufacturing. Using an additive process successive layers of material are laid down in different shapes. 3D printing is different from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes). A materials printer usually performs 3D printing processes using digital technology. 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. History of 3D Printing This technology was called Rapid Manufacturing; a term coined by inventor S. Scott Crump who founded Stratasys in the late 1980′s. During the same time the similar technology was called additive manufacturing or stereolithography and was created by 3D Systems founder Charles ‘Chuck’ Hull. While these two companies are market leaders, the entire publicly traded market cap for 3D printing companies is comparatively small, roughly 2 Billion USD. Many companies that work in this...

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, the inception of this technology would not exist. Following that, we will answer the following questions: (1) What is 3D printing? What is the science behind it?

...1. General Introduction to technology Technology is a vast area that wraps the majority of the world. Emergence of technology is the milestone of the world history. Ever since the invention of fire from rubbing two stones, technology has enormously developed in almost all the parts of the world. The context surrounding the emergence of technology matters. The reason for the emergence at that particular time and the impact and the consequences of the emergence of that particular technology play important roles in relating the context. This paper focuses on two major expanding technologies; mobile phones and 3D printing. 1.1. Introduction to 3D printing Three dimensional printing â_œemploys an additive manufacturing process whereby products are built on a layer-by-layer basis, through a series of cross-sectional slicesâ__ (Berman, 2012, para.2). 3D printing is compromised of various other technologies and the commonly used software is the Computer aided design also known as CAD. 3D printing is a developing concept that is yet to bring a lot of new creations into the world of technology. 1.2. Introduction to Mobile phones Mobile phone is a mobile device traditionally used to make and receive calls. There are many categories in mobile phones. For example, smartphone is â_œa category of mobile phones that read email, take pictures, and surf the internet in addition to making and receiving callsâ__ (Flew & Smith, 2011, p.72)...

...• www.Mojo3Dprinting.com • 10 CASE STUDIES A New Mindset in Product Design 3D printing can help bring better products to market faster By Stratasys Inc. What is 3D printing? The terms “3D printing” and “additive manufacturing” refer to processes that automatically build objects layer by layer from computer data. The technology is already well-used in many sectors including transportation, health care, military and education. Uses include building concept models, functional prototypes, factory tooling (such as molds and robot-arm ends), and even finished goods (such as aircraft internal components). The aerospace and medical industries in particular have developed advanced applications for 3D printing. 3D printing is sometimes referred to as “rapid prototyping,” but this term does not encompass all current uses for the technology. Materials used in 3D printing include resins, plastics and, in some cases, metal. 3D PRINTER Since 3D printing’s inception, system reliability and model quality have increased, resulting in diverse applications. At the same time, prices have gone down to the point where some systems are affordable even for small businesses. In a 2011 report, Wohlers Associates predicted that worldwide annual sales of additive manufacturing systems will reach 15,000 units by 2015 — more than double the 2010 rate. Lower-priced professional systems will drive most of this growth.1 In FDM Technology™, printer software on the user’s Windows network or workstation...

...Jimmy Hernandez 11/24/2013 NT1110 Computer Structure and Logic Week 10 Research Project 3D Printing Today and Tomorrow I chose to do my research paper on 3D printing, were we are today and what the future looks like. While researching this project I learned that 3D printing has been around since the 80’s, and that it is also known as additive manufacturing. I chose this topic for a few reasons; first off this is a topic that has interested me fo a while now and I enjoy learning more about it. I believe this technology is going to have a huge impact on our future, like the computer, and the internet it will change the way we do things. I like that its impact is not limited to one area. I highlight in my project seven different areas that 3D printing is already being used and is reshaping those industries. One of these industries is architecture, construction, and engineering. Architects are using 3D printing to save time when putting together their scale models. In the future there will be no limitations to their designs; the reason for this being that construction companies are now experimenting with 3D printing to build parts of buildings. They have started to print using concrete and have been able to print up some wild angles and designs. These were difficult to pull off before because it was hard to make the form to pour the concrete. In the future architects and project managers will be able to work together and print sections of a building in one...

...Personalizing Medicine By: Daniel Ostroff 12-09-2009 I believe it is absolutely essential to take steps to further personalize medicine. There are too many generalized treatments that may work for most patients, but still a great many patients with slight irregularities are not eligible because of these slight differences. For example, research is being done at the BIO5 Institute at the University of Arizona by Dr. Jonathan VandeGeest and his laboratory to switch the commonly used generalized metallic stents to treat an aortic aneurysm to custom manufactured Functional (due to the use of dendrimers for drug delivery) Polymeric Endoluminal Paving prototypes. The development of these customized prototypes for aneurysm patients is a massive step forward in personalized medicine. The traditional procedure to correct this condition involved complex open-chest surgery. Depending on the size and growth rate of the aneurysm, surgery can take many hours and may require multiple return visits. During surgery, the two traditional treatments are aortic grafts or metallic stents. The grafts are a wire mesh that is sewn into place to prevent further growth and leaking, which involves an extremely dangerous and invasive procedure. Otherwise, a generalized metallic stent is used, but because this device is pre-formed, it will only fit a select group of patients whose aorta is in a straight and vertical orientation. Any other shape and the treatment...

...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. There were two librarians who decided to raise funds to have two additional 3D printers added to another library. The librarians also organized a program for children...

...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...

...The vocational area of my selection is Graphic Design. Graphic Design is the art or skill of using typography and images to compose a visual message, usually conveyed in magazine covers, book covers, advertisements, posters and so on. It uses a variety of software, from the likes of adobe photoshop, to the simple Microsoft word, but may also be done by hand by using paints and stencils. Following this vocational area, I will now further explore what graphic design is, where it comes from and the opportunities and disadvantages that come with it. Going back to the origins of Graphic Design, this study will take you back to the ancient Chinese, Egyptian and Greek civilizations where it was bountifully used in manuscripts. Throughout those years and for many more after, Graphic design had made very little advancements, dissimilar to the likes of painting and sculpture that were evolving with thanks to the Renaissance. It wasn’t until the 15th century, when printing was invented by Johannes Gutenberg, that graphic design was then allowed to advance and evolve from what it was for hundreds of years. In the early 19th century Graphic Design began to flourish in the western parts of the world. It began to be recognized as a profession and people began to specialize in the job. The industrial revolution brought in many new opportunities for Graphic designers due to the new production methods. As Ireland is widely known to be a slowly developing country, Graphic Design had little to no...

...Animation refers to the creation of the sequence of images drawn, painted, or produced by other artistic methods that change over time portray the illusion of motion. Animators are artists who specialize in the creation of animation. Animation has 2D and 3D, for 2 dimensional figures are created or edited on the computer using 2D bitmap graphics or created and edited using 2D vector graphics. This includes automated computerized versions of traditional animation techniques, for 3 dimensional is digitally modeled and manipulated by an animator. The animator usually starts by creating a 3D polygon mesh to manipulate. A mesh typically includes many vertices that are connected by edges and faces, which give the visual appearance of form to a 3D object or 3D environment. Lotte Reiniger is a European Animation artist from Germany and was a German film director and the foremost pioneer of silhouette animation, she anticipating Walt Disney by over 10 years. Reiniger made over 40 films over her career all using her invention. Lotte Reiniger was born in Berlin Charlottenburg, German Empire on 2 June 1899. She died on 19 June 1981 at the aged 82 years old a t Dettenhausen, West Germany. She active for 61 years from 1918 until 1979.
