| Abstract: | Fundamental experimental study on nano-Al 2O 3 bulk materials produced by selective laser sintering technology was achieved. At the same time, SEM and X-ray analysis were used to analyse the microstructure of the sample of bulk materials. The result shows that the nano-Al 2O 3 powder materials can be sintered to bulk materials with the proper process parameters. The bulk material is compact and behaves the sub-structure, and the grain dimension of it is close to the original dimension of powder materials. |
