Abstract
With rapid prototyping introduced to the process of nano material,experiments on slective laser sintering of nano-alumina are carried out and effect of sintering parameters on the process is analyzed systematically.A reasonable selective laser sintering technique of nano-alumina which can be used to fabricate nano-structured parts with free shape is obtained and verified with a multi-layer sintering experiment.The component and the microstructure of the sintering production is tested.It is indicated that with the selective laser sintering technique obtained above,nano-alumina can be processed to manufacture three-dimension nano-structured parts with free shape,the crystal size of the production is almost kept the same as that of alumina powder.
