Abstract

One of the main goals of researchers in metal powders laser sintering, is optimization of process parameters in order to close out the main properties of the raw materials have been produced to the piece. For this purpose, many experiments have been carried and parameters such as density, hardness, micro hardness, strength, surface finish, appearance, and residual stress have been studied. In this paper the influence of parameters such as laser power, scanning speed, and powder material and etc. on output parameters such as penetration depth, strength, BALLING PHENOMENON is investigated. In order to produce a multi-layer fully dense parts by the process of pulsed laser, to optimize the performance of the laser and material parameters at first, it is necessary to single layers is investigated. Experiments carry out on free powder bed depth is 5 mm. Each piece of a single layer on the substrate with once laser scanning powder is produced. Movement of the laser beam on the surface produce a washer with 20mm diameter.
