Abstract
The technology of laser sintering is introduced. Based on the researching of laser heating property, power thermal physics parameters, as well as laser sintering process, a numerical model of the temperature field during length- alterable line-scanning laser sintering of polymer-coated metal powder has been constructed. The calculations of numerical model have been finished by the using of Finite Element Method (FEM). The temperature field during laser sintering was measured to verify the calculated results. Experimental results show well conformity between them.
