The subject of the invention is a method of producing composite elements (1) or (1 ') with a hybrid structure, a print head for their production and a composite element with a hybrid structure, applicable in the production of components with the required high directional stiffness and mechanical strength with minimal weight. The essence of the method according to the invention is that in the first stage of the method, a structural core (1a) or (1'a) with a non-homogeneous structure is printed in the 3D printing technology, and then, in the second stage of the method, the outer layer (1b) is printed with a continuous fiber in a polymer matrix on the surface of the structural core using a 3D printing technology.
