ABSTRACT
Shell-like or plate-like supporting structures, for example for hulls of watercraft or aircraft structures, for instance wing or tail structures, motor 5 vehicle bodies or their subassemblies, propeller-blade structures or wind rotor-blade structures, are obtained by forming one or more panels (P) using an additive-manufacturing technology, for example FDM (Fused Deposition Modelling) technology, in such a way as to obtain panels with a lattice of stiffening ribs (3) on at least one face of the panels. In one 10 example, the stiffening ribs are hollow and are formed simultaneously with forming of the panel, preferably using FDM technology, by moving a dispensing head (1) that dispenses a continuous thread of material according to a closed-loop path to form each layer, or else according to a path between two opposite ends that is followed back and forth in the two
15 directions to obtain different layers of the panel and that includes loop shaped stretches to define the aforesaid hollow ribs. The loop-shaped stretches can be defined with or without overlaying of the portions of thread corresponding to the start and end of each loop. The cavities of the ribs can be filled with additional reinforcement material, for example resin
20 (R) and/or are used for the passage of cables (4) or service ducts (5) or as ventilation ducts (6) and/or are used to engage within them elements of connection between the panels (P). The method makes it possible to obtain shell-like or plate-like supporting structures that are extremely light and that nevertheless present the necessary characteristics of structural
25 strength, at the same time guaranteeing that smooth and fair surfaces are achieved on the outside of the structure.
