1. A method for preparing a flat filament of an X-ray tube, comprising:
obtaining a three-dimensional (3D) model of the flat filament;
obtaining a predetermined parameter, wherein the predetermined parameter includes a scanning direction of laser, wherein the scanning direction of laser is perpendicular to a principal stress direction of the flat filament after the flat filament is heated and expanded during use, so that a growth direction of crystal grains of the flat filament is perpendicular to the principal stress direction of the flat filament; and
controlling a 3D printer to perform, based on the 3D model and the predetermined parameter, a laser scanning on a raw material to obtain the flat filament, wherein the flat filament includes a plurality of gaps so as to define a conduction path of the flat filament in a meander form.
