Resumo

Several emerging rapid prototyping technologies are based upon laser-induced, non-isothermal sintering of solid materials from originally-porous powder. In this study, a model is developed which is capable of predicting the shape of a consolidated object fabricated by this method. The model includes description of the relevant modes of heat transfer, along with a description of powder motion induced by local heating. Model predictions are compared to experimental results, and the model is subsequently used to perform parametric simulations.
