Process for forming equal-wall-thickness reducing fuel spray rod through selective laser melting

The invention discloses a process for forming an equal-wall-thickness reducing fuel spray rod through selective laser melting, and belongs to the technical field of additive manufacturing. The processfor forming the equal-wall-thickness reducing fuel spray rod through selective laser melting comprises the following steps of: S1, establishing a three-dimensional model of an equal-wall-thickness reducing fuel spray rod; S2, determining the forming direction of the equal-wall-thickness reducing fuel spray rod; S3, adding supports; S4, setting selective laser melting forming process parameters; S5, forming the equal-wall-thickness reducing fuel spray rod through selective laser melting; and S6, carrying out post-processing. According to the process for forming the equal-wall-thickness reducing fuel spray rod through selective laser melting, the number of processing procedures of the equal-wall-thickness reducing fuel spray rod is greatly reduced, the turnover time is greatly shortened, tools and clamps are not ne
