Advantages And Disadvantages Of Laser 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.

Also known as additive manufacturing because 3D printing is the process of making an object by depositing material by layers at a time. This is useful and was created because many businesses use subtractive manufacturing, where they tend to have material and carve into it and make something out of it, thereby wasting a lot of material. While using the additive manufacturing they are able to use the material with 98% efficiency to create something, which is why 3D printing is burgeoning and more research is being conducted to increase the 3D printers

Some car manufacturing companies are already using 3D printing tool that help in increasing the strength of car parts and is also

3D printing is chosen because it has lower costs than the other manufacturing techniques, easy to duplicate the products and higher product security. For example, the chief designer of Futurefactories stated that it is the same price to produce two different products as producing two identical ones therefore the economies of scale concept does not apply.(Thilmany, 2009, p. 39, cited in Berman, 2012, p.159).

“Although 3-D printers are not yet a standard part of home-computing equipment, the latest generation of devices, such as Cube® by 3D Systems, the Cubex™ or Makerbot’s Replicator™2X - which retail for between one and three thousand US dollars - are bringing the possibility of home manufacturing one step closer to reality” (Jewell). Now the biggest difference between traditional manufacturing and 3D printing will be the emergence of mass customization. Goods will be, “infinitely more customized, because altering them won’t require retooling, only tweaking the instructions in the software. Creativity in meeting individuals’ needs will come to the fore, just as quality control did in the age of rolling out sameness” (D'Aveni). When you have a product that is printed out individually from software with your own customization, then there would be no reason in buying a product that will look like something another person can own because of its ordinary accessibility. Creating physical 3D models in a fast, easy and affordable way has great potential, especially when you can do it in the comfort of your home.

As the new age of manufacturing is beginning, it brings with it the associated technology, which caused the change. In this case it is 3D printing. There are significant revolutionary differences between using 3D printing for manufacturing and traditional manufacturing techniques, like the ones that are more commonly used.

Then 3D printing is one of the best options for manufacturing due to one reason compared of using

Factories: Assembly lines and supply chains are reduced. Factories have highly developed and specialized 3D printers. Spare parts are 3D printed on demand instead of being stock-piled. Broken goods can be repaired by simply printing the spoiled component.

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

Rapid production of models, 3D printing allows rapid production of models or small-scale versions of the real target. it can helps engineers and researchers planning the factual object and catch any defects in the design, which may impact functionality and the quality.[7]

With the rapid development in technology over the past few years it is understandable that many new manufacturing techniques have arisen in order to fine tune the precision of the characteristics and finishes of products. This report will discuss some of these manufacturing techniques and their disadvantages and advantages.

A wide range of application domains, including medicine, aerospace, defense, and automotive industries, have benefited [1–3]. The term “ALM” relates to several different types of additive manufacturing, which can be categorized in different ways [2]. Among them are such types as extrusion (fused deposition modeling), wire (electron beam freeform fabrication), powder bed (selective laser melting) types and so on. The ALM technique studied in this work is selective laser melting (SLM) where metal powders are selectively melted by a focused laser beam in layer-by-layer

Manufacturing prototypes with 3D printers costs are low compared to other manufacturing companies. We can increase the production of goods faster, cheaper and even strengthen the durability of the product. 3D printers may cost high but look at the benefits that it can give to society.

In 21st century 3D printer becoming one of the most discussed and popular technology in the world. There are many advantages and disadvantages of 3D printer are discussing on TV, in internet and in other well known magazines. Thus, positive and negative sides of 3D printing are one of the significant issues for today’s time. 3D printing technology is quickly advancing and is soon expected to become one of the basic leading technologies in society. With more advancements being made every day, a lot of discoveries have been unveiled on many other applications of 3D printing that make it an extremely important technology for society. Also, the fact that the price of 3D printers is declining, has attracted a lot of attention across the world to this revolutionary technology (Wellington).

According to 3Dprinting.com (n.d.), 3D-printing one of the additive manufacturing process by transforming 3D digital file in to a real solid object and it reach the using of additive processes. Additive process means creating an object by laying down successive layers of materials, we can see the sliced horizontal cross-section of the corresponding object during the manufacturing process. The essay is going to discuss about the recent insight of the 3d-printing industry base on the seminar that spoke by Dr. Wendy Lee.
