Process simulation of Multi-layer and Multi-channel Selective Laser Melt of Al2O3 Ceramics Based on Temperature Field

摘要

Based on the temperature field theory and ANSYS software,the simulation model of Al2O3 ceramics selective laser melting(SLM)temperature field of multi-layer and multi- channel was established,and the analysis process of SLM temperature field simulation was designed.The temperature distribution of Al2O3 ceramics SLM temperature field and molten pool forming characteristics were researched.When the laser power is 105W,the scanning speed is 50mm/s and the thickness of powder layer is 0.25m,there is no remelting in adjacent molten channels in the same layer and multiple layers.Laser power and scanning speed are the main factors that whether remelting occurs in adjacent molten channels and multiple layers.
