Abstract：AIM:To analyze the temperature field distribution according to the finite element model of tem-perature field of Al2 O3 /ZrO2 ceramic powder in selective laser melting.METHODS:In consideration of the material thermal property parameters,“Element Birth and Death”of ANSYS12.1 parametric design language (APDL)was used to simulate the temperature field distribution and to verify experimentally.RESULTS:The three-dimensional fi-nite element model of temperature field was successfully established by APDL.Simulation results showed that the tem-perature field distribution was asymmetric.With the increase of scanning time,temperature roses and the temperature gradient reduced.CONCLUSION:The finite element model can effectively reflect temperature field distribution.And this finite element model can be used for further simulation experiments.
