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.
