A dispensing head (1) for an apparatus for making three-dimensional physical objects of predetermined shape by sequentially depositing multiple layers of solidifying material on a base member is disclosed. The dispensing head (1) comprises a tubular passage (2), extending from a receiving inlet (3) to a dispensing outlet (4). As a special feature, the tubular passage (2) comprises integrated drive means (9), such that the drive means (9) can arrange strands (8) of solid material to be processed in a driving zone (D) located between the receiving inlet (3) and a liquifying zone of the tubular passage. L'invention concerne une tête de distribution (1) destinée à un appareil servant à fabriquer des objets physiques tridimensionnels d'une forme prédéterminée en déposant de manière séquentielle plusieurs couches de matériau de solidification sur un élément de base. Cette tête de distribution (1) comprend une passage tubulaire (2) s'étendant d'un orifice de réception (3) à un orifice de distribution (4). Ce passage tubulaire (2) est caractérisé par un dispositif d'entraînement intégré (9) qui peut arranger des brins (8) de matériau solide de manière que ceux-ci soient traités dans une zone d'entraînement (D) située entre l'orifice de réception (3) et une zone de liquéfaction du passage tubulaire.
