Selective laser melting forming process based on control surface bionic structure

The invention aims to provide a selective laser melting forming process of a control surface bionic structure. The selective laser melting forming process comprises the specific steps that 1, three-dimensional cartographic software UG is used for modeling of the control surface bionic structure, machining allowance adding and powder clearing hole setting; 2, three-dimensional digital-analog processing software Magics is used for conducting forming and placing, model repairing, support adding and slice filling processing on the control surface bionic structure; 3, the control surface bionic structure is prepared through selective laser melting forming equipment; and 4, after the selective laser melting forming process is completed, powder in an inner cavity is discharged through an inner powder removing hole and an outer powder removing hole, the lower surface grid supporting and solid supporting structure is removed, and the final control surface bionic structure with the same size as the three-dimensional mo
