Abstract

In this research, the thermal analysis of additive fabrication by DMLS method has been investigated. In the DMLS method, the metal powder is melted by a Laser Heat source and finally a solid t hree dimensional piece is formed This analysis was performed by finite element method in Abaqus software. L aser Heat distribution is considered Gaussian. T he mechanical and thermal properties of the powder are considered as a function of melting temperature. Finally, the results obtaine d by the finite element method are compared with previous re searches. The effects of Laser speed and power on temperature distribution have also been investigated.
