Method for manufacturing a line component

A method for manufacturing a line component for conducting a fluid, the method comprising:

• additively fabricating a line component that includes a line element and a line branching by:
• piling, in a predetermined region, a particle-shaped material on a base layer of the line component to be fabricated;
• and
• heating up the piled particle-shaped material by means of a heat source such that particles of the particle-shaped material combine with each other and/or with the base layer within predetermined dimensions;
• incorporating a notch on an inside of the line element, the notch serving to relieve a tension in a loaded state of the line component or the line element;
• guiding a particle-filled gas stream through an interior of the line component in order to smooth an inside of the line component;
• and/or
• pressurizing the line component to produce a plastic deformation on an inner surface of the line component,
• wherein the line element is configured to conduct a fluid from a first opening to a second opening, wherein the line branching connected with the line element is configured to conduct the fluid to a third opening, and wherein an outer region of the line component is designed load-compliant by a numerical optimization program to include a multitude of irregular topological structures in the outer region.
