The Production Of Additive Manufacturing

3D printing or additive manufacturing is a process of making three-dimensional solid objects from a digital design. The creation of a 3D printed object is achieved using additive processes. In an additive process the desired object is created by laying down successive layers of material (usually molten alloy or plastics) until the entire object is formed. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

3D printing might seem like a daunting task only accessible to the elite members of the market, but because of its continuous growth and advancement, 3D printing has developed into technology available to nearly anyone and everyone. 3D

Why go to stores and spend lots of money buying toys, jewelry, cups and many other plastic utilities when you can only press one button and print them out for yourself. This futuristic idea is not only innovating the scientific and technological world, but it is also innovating modern day households. The possibilities of 3D printing are extremely captivating, making this one of the most exciting innovations in recent times. 3D printing, also known as additive manufacturing, makes three-dimensional solid objects from a digital model or command. To picture how this process works, 3D printers use an additive process, where adding layers of a successive material creates an object. Traditional machines, however, uses a subtractive process by

You pack everything that you think you need for deployment. You conduct your demand analysis that leads you to believe that what you packed is just what you need. Every deployment you had been on before confirms that those are the assets that will lead you to mission success. However, this deployment is different and just about everything you brought is not required and to source it from else where will take too long. In the near future the most viable solution will be to print it. As 3D printing now formally known as Additive Manufacturing (AM) evolves, the possibility of have everything you need at your fingertips will have a profound impact on your operational readiness. Implementation of additive manufacturing at the Intermediate level (I Level) of a Marine Aviation Logistics Squadron, will drastically reduce the acquisition and production lead-times associated with low demand items, items that are impacted with obsolescence, and drastically reduce cost and footprint of conventional logistic models.

3D printing is a process where a digital design is turned into a physical object using additive manufacturing. In contrast to subtractive manufacturing, where an object is carved out of a larger solid piece of material, additive manufacturing involves

Overview: On many roadmaps for Additive Manufacturing (AM), repeatability is listed as a challenge that must be overcome before the commercialization of AM [1]. Recently, researchers have tried to optimize the design of AM parts through Finite Element Modeling [2]. Optimally designed AM parts decrease the variation in printed parts, but due to the high uncertainty in the AM process, these methods have only improved repeatability marginally. There are currently no methods tailored to

3D printers have been in the market for over 30 years up until now, starting at the 1980 's. Since the beggining, 3D printers have greatly developed but they are still in the process of researching and improving. The 3D market is expected to have many future advancements that will highly contribute to the different industries, including medicine, CAD/CAM dentistry, automotive, aerospace and defence, and the printing industry itself.

3D printing has been quoted by the Financial Times and from other sources as, “Possibly being bigger than the internet”(Jun 21, 2012). The earliest 3D printing technologies first became visible in the late 1980’s. There are multiple different types of 3D printing technologies, which process different materials in unique ways to create the desired object. Since the emergence of 3D printing, developments and improvements to the process and the materials has greatly expanded the various applications. 3D printing was invented as a means of speeding up the early stages of product development, using simple material, and multiple applications.

To prepare a digital file for printing, the 3D modeling software “slices” the final model into hundreds or thousands of horizontal layers. When the sliced file is uploaded in a 3D printer, the object

Within the past decade, innovation in the field of 3D laser-based printing is revolutionizing the efficiency the world operates at. Primary process such as selective laser sintering (SLS) and selective laser melting (SLM) will be proven to illustrate the impact they are having on world industry. Applications of 3D Laser-based printing allows the completion of complex geometries to assist in aerospace, biomedical and much more. Laser-based printing dates back to the late 1980’s with the first commercially produced 3D printer (SLA-1, 3D systems), although methods of constructing parts using additive approaches dates back over 100 years (Bourell, 2016). The first use of a 3D printer was in 1990 by Bourell who created a metal part by the laser

3 D printing also known as additive manufacturing or stereolithography or rapid prototyping has been predominantly explored for the past few years. 3D printing technology is called additive manufacturing because the material is built from scratch, without any loss in existing volume of an object by chipping, drilling or cutting. (Tony Hoffman, 2016). The fundamental concept of additive manufacturing is printing an object by successive deposition of layers of various materials. Before an object can be 3D printed, it first has to be sliced into thousands of horizontal and vertical planes in Computer Aided Design (CAD). There are similar software like CAD which are used for the purpose of 'Slicing '. Some of these software are CAM- Computer Aided Manufacturing and 3D Scanner. These horizontal and vertical planes together make up the 3D model of the object. Once a virtual design of the object is prepared, also called as ‘the feed’, a file in the ‘.stl’ format is provided to the printer which then prints the desired object. Though the basic outcome of 3D printing is same, different technologies have been developed as per its need in the industry. Based on personal requirements, an object can be customized on small as well as large-scale.

AM can create complex geometries; however the process struggles to maintain geometric accuracy of products (Ameta). Geometrically inaccurate products manufactured for use in the medical field may subject patients to unnecessary complications that could have been avoided if geometric tolerances were kept. Here I review, research that studied the parameters of the AM process and the role each parameter plays in maintaining or

This graph depicts the comparison between traditional manufacturing process and 3-D manufacturing. For a firm to test a new product in the market or for testing a new prototype they have a high cost to manufacture small units or may have a stock pile if they decide to manufacture at lower cost. 3-D printing can help reach their goal without higher cost or stock pile up.

The first step of this process is to design the model of the object of desire using Computer Aided Design (CAD) Software. The model should be the exact replica of the object to be created by 3D Printing. In the 3D Digital Model itself we need to slice the object into very thin layers of about 0.03-0.1mm thickness. These layers will serve as the guidelines for the printer to print the object.

Initiation of 3-D printing took place in end 1980s. Fundamentals of 3-D printing were laid by Japanese Professor. Although he was not able to contribute 100% with his idea, but later on, Mr. Charles Huck carried on with this idea and finally came up with a machine that can create prototypes. Later he also co-founded a 3-D manufacturing company that is right now one of the largest 3-D company in the world and contributes a lot to modern era problems. After this initiative, progress on additive manufacturing process or 3-D printing got started, and since then, it became one of the most important sector of science, specifically engineering, as it have produced a lot of useful results and have also simplified some lengthy tasks, transforming them into efficient, accurate and cost effective activity.
