N2 - For simulating the geometry of melt pool’s cross section more accurately in Selective Laser Melting (SLM) process, modeling the volumetric heat source is considered as the key issue. In the present study, a three dimensional finite element heat transfer simulation with new volumetric heat source is proposed to simulate the geometry of melt pool’s cross section during SLM process. The approach to build up the volumetric heat source is based on the modified sequential addition method to simulate the powder bed and the Monte Carlo ray tracing simulation in Zemax to calculate the energy distribution along the depth of metal powder layer. For validating the proposed simulation model, the simulated result of the contact-width between melt pool and substrate is compared with experimental result presented in the existing literature.
