Usages of 3D printing
3D printing is emerging as an extensively adopted technology by the additive manufacturing industry. This is a highly efficient and useful process that allows the printing and assembling of different materials in a single go. The creation of 3D objects by using this technology is much simpler and easier, and the cost associated with it is also affordable. In this process, basically a 3D file is generated on the computer initially, and then it is used as a basis for the purpose of slicing. These sliced parts or materials are than assembled and printed one over other. The parts or materials that have been sliced and then printed for the creation of 3D object can have different mechanical as well as physical properties. The major advantage of the 3D printing technology is that it is very cost effect and is great for desktop factories.
There are different methods that are being used for the purpose of this three dimensional printing, and depending upon the feasibility and availability of material; you can choose the one that suits you the best. The basic difference comes up at the time of the slice or layer creation. The layers can be produced by using different materials and techniques. Although, each method being used for the purpose of 3D printing has some pros and cons associated with it, therefore the choice of one over the other can differ depending upon the suitability of the company’s requirement.
Methods like SLS (Selective laser Sintering) and FDM (fused deposition modeling) basically make usage of the melting material; whereas others make usage of the liquid stuff. So the basic aspects that are given importance are those of the momentum, price, material being used and the color capacity. Selective laser sintering and direct metal laser sintering are the methods that make usage of the selective fusing of print media through the laser application for the sintering purpose. Ink jet printing system is considered the fastest method that allows full color prototype printing by making usage of the plaster or resins powder over the layers for the purpose of printing. On the other hand, digital light processing or DLP makes usage of the liquid polymer. Apart from this, molten polymer is used for the rapid prototyping in case of fused deposition modeling.
3D printing is certainly a great and inspiring technology that has brought several benefits and simplicities for the engineering world. Today, it has its applications in different areas majorly those of metal casting, artistic expression, education, design visualization, fossils reconstruction in paleontology, architecture, prototyping, pathology and medical to name a few. Moreover, a lot of research is still in progress in the area of three dimensional printing, and there is a lot that is yet to be explored in this vast area. Like, 3D printing is expected to bring advantages to the fields of bio printing, real object replication and organ printing. The usage of 3D printers that are considered costly today is expected to reach the normal users very soon, at their affordability.
