Research on measurement method of selective laser sintering (SLS) transient temperature

During selective laser sintering (SLS), transient temperature has direct effect on prototyping mechanism and quality. The infrared thermograph non-contact testing method is proposed in this paper. The testing results are compared with numerical simulation results. The results indicate that the on-the-spot survey trend agrees with the simulation trend, and the proposed method provides a steady experimental base for selecting sintering parameters and calculating thermophysical parameters reasonably.
