| Popis: | Additive manufacturing has advantages of fabricating complex parts at very greater speed with complete freedom for designer. LENSTM is an additive manufacturing that uses 3D CAD model for depositing metal products directly from metal powder. The effect of process parameters like Laser Power, Scan speed, powder flow rate and working distance on Porosity, instrumented Vickers Hardness and Bulk Hardness Top and Bottom layers for LENSTM deposited components were investigated and the values are compared with wrought alloy. The density and Hardness obtained from LENSTM Samples are Higher than that of Conventional Methods. The Laser Power was significant factor according to Taguchi Analysis. |
