Abstract：Aimming at rapid manufacturing of complex shape of the product for single and small batch，the key technologies of 3D

printing based on stereo lithography appearance（SLA）were studied，with the centrifugal pump impeller which has typical complex shapes

as a research object. The main research contents of this include the CAD optimization design，the pre- processing technology，the

processing parameters design and the post- processing technology. The results have laid a solid theoretical foundation for further

application technology research of 3D printing.

Key words：3D printing；stereo lithography appearance（SLA）；optimization design；post-processing；impeller
