采用激光选区熔化技术进行了Al2O3粉末和浆料的基础实验研究。实验结果表明，Al2O3粉末成形效果较差，而Al2O3浆料成形效果较好；激光功率对Al2O3浆料试样表面的质量具有重要影响，表面质量随激光功率的增加而不断提高。当激光功率为200 W，扫描速度为90 mm/s时，Al2O3试样维氏硬度均值约为14.7 GPa。

The technology of selective laser melting is used to conduct the basic experimental study on Al2O3 powders and slurry. The experimental results show that the forming effect of Al2O3 powder is worser, and in contrast that of Al2O3 slurry is better. Laser power has important impact on the surface quality of Al2O3 slurry samples, and the surface quality continuously upgrades with the increment of laser power. With the laser power of 200 W and scanning speed of 90 mm/s, the average Vickers hardness of Al2O3 sample is about 14.7 GPa.
