Abstract: A method for the construction of three-dimensional fibre-reinforced structures from a pre-existing object, where said method comprises the following steps: —acquisition of the initial three-dimensional geometry of the pre-existing object and of the relative spatial coordinates of its position with respect to a numerically controlled machine (10) equipped with at least one printhead (12); definition of the path to be followed by the above-mentioned printhead (12) in order to add the desired amount of material to the pre-existing object to obtain a desired final object; —deposit of the material on the pre-existing object by means of said printhead (12) by layering the composite material on the pre-existing object according to programmed trajectories, where such programmed trajectories are calculated according to the path that said printhead (12) must follow to add the desired amount of material to the pre-existing object; —extraction of the reinforced object after operations are concluded.

Abstract: An apparatus and method for three-dimensional printing of composite materials of continuous fibre, in which a feed head for feeding a compound material of continuous fibre is moved so as to print a three-dimensional object; a means for relative movement between the feed head and the three-dimensional object exerts a drawing force on the compound material of continuous fibre, so as to bring about the feeding of the material; this material is realized at a station arranged upstream of the feed head.
