  • Numerical computation model for the thermal process of selective laser sintering of powders were presented to predict the sintered depth in selective laser sintering.The factors of the material thermal physical properties varing with the temperature and the un-uniformed distribution of laser intensity across the beam diameter had been taken into account in the computation model.The problem was formulated by a three-dimensional transient heat transmission model and solved by the finite differential method.The results show that the predicted sintered depth accord with the measured value and the model can be used to estimate the sintered depth in selective laser sintering.
