The Selective Laser Sintering of Polycarbonate
TL;DR: In this article, a state-of-the-art adaptive mesh 2D finite difference code is used simultaneously to consider heating and sintering and its results compared with a classical moving heat source model and with experiments.

TL;DR: In this article, a comparison between the three and experimental results is used to evaluate their ability reliably to predict the behavior of the physical process, and the analytical model has some value, provided appropriate mean values are used for thermal properties.
