Fundamental Models of Selective Laser Sintering of Metal Powders

Abstract

This project involves state-of-the-art, flindamental modeling of the laser beam-material interactions associated with Selective Laser Sintering (SLS) of single and multiple components powders. The research tasks carried out in the project include modeling of (I) coupling of laser beam and metal powders, (2) Liquid phase sintering of two-component metal powders, (3) Liquid phase sintering and Selective Laser Powder Remelting (SLPR) of single-component metal powders, and (4) the post-processing of the sintered parts with infiltration of liquid metal. The developed models are capable to handle any material combination, and can handle selective placement of different materials prior to laser scanning.
