| Abstract: | Selective laser sintering of coated sand was investigated with a number of experiments.Effects of different process parameters such as laser power,scanning rate,preheat temperature,spot diameter on the dimension accuracy and sintered quality were studied systematically.The mutative tendency of the sample dimension along with the different parameters was summarized and the desired range of temperature of the processing sample after sintering was proposed. |
