Abstract: A motor-vehicle lattice frame that includes a plurality of structural nodes each having a central body and at least one hollow arm protruding from the central body. The lattice frame also includes a plurality of beam elements connected to each other by means of the hollow protruding arms. The structural nodes are made by an additive manufacturing technique and at least one arm of one of the nodes has an end portion opposite to said central body having a channel shape with an open cavity both at a front end of the arm and along one side of the arm.

Abstract: A hinge of a motor-vehicle mobile part includes a first and a second hinge element mounted articulated with respect to each other about a hinge axis. The second hinge element is articulated to the first hinge element by an articulation portion having two pins defining the hinge axis, and projecting in opposite directions from two sides of the second hinge element. The first hinge element and the second hinge element are obtained by an additive manufacturing technique in an already reciprocally articulated condition, with the pins mounted with clearance within respective articulation seats formed on two flanges of the first hinge element adjacent to the sides of the second hinge element. The hinge also includes two bushing-shaped members, each interposed between one of said two pins and the respective articulation seat.
