Summary: | The invention discloses an SLM forming method of a high-temperature alloy valve body structural part. The SLM forming method comprises the following steps: 1, establishing a three-dimensional model ofa preforming part valve body; 2, designing the support structure of the valve body model; 3, decomposing the data of the valve body model: carrying out data decomposition and hierarchical processingon the valve body model along the Z-direction vertical plane of the valve body model; 4, printing the valve body model layer by layer: carrying out layer-by-layer printing from a substrate to obtain avalve body formed part; 5, cutting and separating: carrying out linear cutting along the upper end face of the substrate to cut and separate the valve body formed part and the substrate; 6, carryingout surface treatment: carrying out surface sand blasting; 7, carrying out thermal treatment: carrying out stress relief annealing and solution treatment; 8, removing the support structure; and 9, finish machining.
