Effects Of Laser Scan Speed1EFFECTS OF LASER SCAN SPEED ON POROSITY AND DIMENSIONAL CHANGE OFTHE SELECTIVE LASER MELTING COMPONENTS.By NameCourseInstructorInstitutionLocationDate
Effects Of Laser Scan Speed2IntroductionAluminum alloy and selective laser melting.Over the years previous, the 3d that is also known as the fabrication of the substance has led tothe increase of the interest that will complicate it in the industry and the scholarly. more had beendone on the AM innovation with the result distribution that includes the ISO and the ASTMguideline survey papers, books unique AM diaries and report guides.in contradiction to thenormal assembling approaches, am gives the geometry without misuse of the materials andincreasing the cost.in most metals, the system of the AM that is the specific laser liquefying hasbeen the commonly used mostly and this can link to the general application ranges that is from3D to mechanical design with the low volume me.in the selective laser melting a tiny portion of the metal powder is then dispersed at first, and themelting will be specifically done laser shaft within the environment. Similarly, in theexamination of one layer, that stage has to be stopped by that one layer thickness and the powderis to be spread on the upper part of the metals[CITATION DDG12 \l 1033 ].Literature reviewIn most of the work had indicated that the aluminium alloy processing by the selective lasermelting has been so cumbersome, by this the production of understandable components is doneunder high laser power of about 130w to 150w and with laser scanning speed that is slow. Mostof the selective laser melting machine has higher power but that of the laser power is greater thanit thus a significant factor.by combining the higher power and the reduction of the speed leads tomelting thus forming a pool of the melted products that become very difficult to control. Thiswill eventually lead to the balling of the melt and the power distribution system might be

Additive manufacturingThis is a process by which the metal layers are joined together to form a CAD model through thebuilding of objects, this done by combining several layers together. This process is also knownas the standard tessellation language, where the shapes of the materials and the size of thecomponents are defined. The data files are slice into the single layers by the software thus theadditive manufacturing receives it as the instructions. The technology of the additivemanufacturing uses the material in powder form. When the components have been manufactured,several activities have to take place e.g. it has to be polished, filled, cured, or painted withregards to the materials used[CITATION Ian06 \l 1033 ].Advantages of the additive manufacturingIt is important as it uses small extraneous components to produce portions of the object thus anefficient process which reduces the waste during the manufacturing.By using less material during production this method reduces the steps of production thusreducing the amount of the energy consumed[CITATION Ian06 \l 1033 ].This method of production involves less waste thus the materials being used is not wasted duringthe manufacturing process thus an environmentally friendly process.This technique allows the producers to create a prototype. This will eventually save time, intimes of production and development thus reducing the requirements during production leadingto the use of few tools.
Effects Of Laser Scan Speed4With the reduction of the instructors, moulding and the required tools there will be the reductionin the cost of the manufacturing. The additive manufacturing technique allows for the innovation of the designs. Themodifications of the design can be done anytime without extra cost. This technique can help in the reduction of the design complexity. The manufacturing using thistraditional method can also be simply modified by this method[CITATION LEE11 \l 1033 ].Application of the additive manufacturingAutomobile industryThe automotive industries require the development of new products. Since the development ofthe new products are very costly the industry has resorted to the use of the additivemanufacturing technique in the designing and to develop automotive materials, the structure andthe functioning parts of the components like the gearbox, drive shaft, drive shaft of the vehicle,and wheels[CITATION Ian06 \l 1033 ].Biomedical applicationsThe additive manufacturing is a process that saves the life in the medical industry. The expansionof the applications of the additive manufacturing technology in the industry brought about by thedevelopment of the biologic science, biomaterials, and biomedicine has improved the use of thistechnology in the industry. The area of applications is, in the dental application, painted organsand in the bioprinting.Electronics industry
