Modeling and Analysis of the Powder Deposition Mechanisms of Selective Laser Sintering Process, M.Sc. Thesis Sharif University of Technology ; Movahedi, Mohamad Reza (Supervisor)
Abstract
Selective laser sintering is a technique which uses a laser as the power source to sintering some selected points at a bed of powder in order to create a solid structure. In this research the SLS mechanisms of powder deposition is simulated and surface smoothness and layer density created by each mechanism is computed. For this purpose roller, blade and hopper mechanisms are simulated. For this simulation, polyamide 12 (PA2200) which is a common material is used. In this simulation at first powder specifications are extracted according to the references and for particle shape instead of using the spherical particle shape we use a certain shape that is more close to reality which created by...
