According to the manufacturing method of the invention the line component, in particular an additively fabricated line component, comprises a line element for conducting a fluid from a first opening to a second opening, and a line branching connected with the line element for conducting the fluid to a third opening, wherein an outer region of the line component is designed load-compliant by means of a numerical optimization program and thereby includes a multitude of irregular topological structures in its outer region. In the manufacturing method of the line component a notch is incorporated on the inside of the line element, which serves to relieve a tension in a highly loaded state of the line component or the line element, a particle-filled gas stream is guided through the interior of the line component, in order to smooth the inside of the line component and/or the line component is subjected to a pressurization, in order to produce a plastic deformation on an inner surface of the line component.
