Heat Source Model: Advantages And Disadvantages Of Additive Modeler 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.

There is nothing more satisfying than being able to complete a sheet metal fabricating task flawlessly and efficiently. Regardless of what metal component you are using, you can always come up with a utilitarian piece or a work of art for as long as you put patience and dedication to your project.

Picture this, almost out of thin air, what resembles the sole of a shoe starts to materialize from a viscous pool of liquid polymer. This isn’t a scene from a sci-fi movie, it is actually the future of manufacturing. The athletic wear company, Adidas, has already started using 3D printing, also known as additive manufacturing, in their two new highly automated factories. Flashback to the 1980s, invented by Charles Hull, the 3D printer was originally called a stereolithography. Basically, 3D printing uses a blueprint created from software on a computer uploaded to a printer that uses certain materials such as glass, metal, plastic, ceramic, and in the case of

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

Therefore, the limitations of self-production have shifted from hardware difficulties to software or materials issues. The technology is becoming simpler to use, but it might harm light manufacturing industries because some designers may be able to use their own 3D Printers to produce a sample instead of finding established producers that use traditional manufacturing methods. Because of these improvements, the potential for 3D Printing is bright, but the light manufacturing industry might be negatively affected by it.

The laser beam then traces the boundaries and fills in a two-dimensional cross section of the model, solidifying the resin wherever it touches. Once a layer is completed, the platform descends a layer thickness, resin flows over the first layer, and the next layer is built. This process continues until the model is completed. There is also process that uses extrusion tube that flows out melting plastics or other materials that will take shape in 3D object and a process where glue or laser fuse together metal in a similar process to the stereolithography where by the plastic is replace by metal grinds.

It would have been clear by now that 3D printing has some obvious advantages. However, sensitivity to a number of considerations is needed when new boundaries are broken using science and engineering. Following are the common issues that arises out of the emergence of 3D printing

3D printers use a technique known as additive manufacturing which could be seen as a parallel to subtractive manufacturing. Both systems start with a computer generated model and are transferred to an external device that operates on an X Y Z axis system. In simple terms printing is traditionally done by stacking thousands of thin layers on top of each other until the object is completed. While

3D printing, also known as additive manufacturing, is the process of successively layering material to form a 3D object (“What is 3D”). This process begins with the formation of an idea. This object can be anything from a hand, to a vehicle component. Using computer aided design (CAD), the user can transform an idea into a computerized 3D model. However, if the item already exists, the operator can use a 3D scanner to make a digital copy of the object and shorten the process (“What is 3D”). After the user has the digital 3D model, the computer horizontally divides the virtual object into hundreds or thousands of “slices,” as seen in figure 2. The printer then starts producing the object, layer by layer. The printer head moves side-to-side and up and down as it deposits layers of material (“How 3D Printing”). As each successive layer is printed, they are blended so that the human eye can hardly see the individual layers, if at all (“What is 3D”). The mixing process is crucial for the visual and

3D printing has many advantages over traditional construction methods. With the help of 3D printing, an idea can transform a designer’s computer to actual finished product or component, potentially skipping many of traditional manufacturing steps, which includes procurement of parts, creation of moulds, creation of parts using different moulds, welding metal parts together, machining to carve parts from blocks of material and final assembly. It also reduces the amount of material wasted in manufacturing and creates difficult objects with complex geometric structures like fractals which can add strength, or are natural in shape, may reduce weight, or increase functionality. In a typical metal manufacturing, for example,

Objective: Develop a deep learning (DL) approach that incorporates the thermal history and physical parameters of an additively manufactured part to predict distortion for any part geometry.

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

3D printing is a method where three-dimensional physical object’s can be created to any shape from a digital model. In the early 19’s, 3D printing was an impractical idea that was only a dream. However, in 1980 the first 3D printing technology was invented by Charles Hull and it was called stereo lithography. The inventor of 3D printing Charles Hull mention that “This invention relates generally to improvements in apparatus for forming three-dimensional objects from a fluid medium and, more particularly, to stereo lithography involving the application of lithographic techniques to production of three-dimensional objects, whereby such objects can be formed rapidly, reliably, accurately and economically” (Hull, C. W.,1986). People think that 3D printing technology will have a strong grip on to our everyday life’s and it has more positive benefits than the negatives. Moreover, 3D printing can
