Equipment and process for three-dimensional printing composite materials

Abstract

Equipment and a process for three-dimensional printing of composite materials are described, said equipment comprising:—a feeding head for feeding at least one continuous filiform element; said continuous filiform element comprising at least one dispersed phase and at least one continuous phase; said feeding head comprising at least one deposition apparatus arranged in its end portion;—a movement assembly for the relative movement between the feeding head (50) and the three-dimensional object (20) to be printed and/or supporting surface (9);—at least one energy source (8) configured to deliver a pre-set amount of energy to said continuous filiform element (4); said deposition apparatus (50) comprises:—a device (40) for varying the shape of the section of the continuous filiform element (4) being deposited, comprising at least one side surface configured to be in contact with the continuous filiform element (4), thus occupying at least one portion of the outer perimeter of the section of said continuous filiform element (4) and so as to define an empty portion on the outer perimeter of the section of said continuous filiform element (4) equal to or greater than 5% of the outer perimeter of the section of said continuous filiform element (4).
