Hinge of a motor-vehicle mobile part

A hinge of a motor-vehicle mobile part, comprising:

• a first hinge element intended to be connected to either a mobile part of a motor-vehicle or a motor-vehicle structure,
• a second hinge element intended to be connected to the other of said motor-vehicle structure or said mobile part of the motor-vehicle,
• wherein said first and second hinge elements are mounted articulated with respect to each other about a hinge axis,
• wherein said second hinge element is articulated to said first hinge element by means of an articulation portion having two pins defining the hinge axis and projecting in opposite directions from two sides of said articulation portion of the second hinge element,
• wherein said pins are formed in a single piece with the second hinge element,
• wherein the first hinge element and the second hinge element are obtained by an additive manufacturing technique in an already reciprocally articulated condition, with said pins mounted with clearance within respective articulation seats formed on first and second flanges of the first hinge element adjacent to said sides of the second hinge element, so that the two hinge elements are permanently bound to each other,
• two bushing-shaped members, each of said members interposed between one of said two pins and the respective articulation seat.
