Equipment and method for the three-dimensional printing of continuous fiber composite materials

Abstract

Equipment and a method for the three-dimensional printing of continuous fiber composite materials are described, and the equipment comprises:—a supplying head (1) to supply at least one filiform element of continuous fiber (4) comprising at least one fiber;—a movement assembly for the relative movement between the supplying head (1) and the three-dimensional object (20) so as to exert traction of the continuous filiform element (4);—a coupling unit to couple a quantity of material powder onto said filiform element (4); said coupling unit (2) being configured to deposit a determined quantity of powder on the continuous filiform element so as to form a prepreg filiform element (4′);—an energy source (6) configured to induce a phase change to the prepreg filiform element (4) from the solid state to the liquid state; said energy source (6) being positioned downstream of said coupling unit (2).
