Abstract

L'invention concerne un mécanisme d'alimentation en filaments pour une tête d'imprimante 3D pour alimenter sélectivement en filaments, comprenant une roue motrice (1) pour alimenter en filaments et un ensemble de rouleaux pinceurs (2, 3) montés sur un culbuteur (4). Il comprend également une tige poussoir (8) reliée au culbuteur (4), le culbuteur (4) étant monté pivotant avec l'axe de rotation (5) et adapté pour tourner par un mouvement latéral de la tige poussoir (8) pour presser l'un des rouleaux pinceurs (2, 3) sur le filament respectif.
