Abstract

A motor-vehicle lattice frame (T) is described here that includes a plurality of structural nodes (N1, N2) each having a central body (1) and at least one hollow arm (2, 3, 4, 30) protruding from the central body (1). The lattice frame (T) also includes a plurality of beam elements (5, 6, 11, 27) connected to each other by means of the hollow protruding arms (2, 3, 4, 30). The structural nodes (N1, N2) are made by an additive manufacturing technique and at least one arm (2, 3, 4, 30) of one of the nodes (N1, N2) has an end portion opposite to said central body (1) having a channel shape (C) with an open cavity both at a front end (12) of the arm (2, 3, 4, 30) and along one side (13) of the arm (2, 3, 4, 30).
