Title (EN) A PROCESS FOR PRODUCING A THREE-DIMENSIONAL GREEN BODY BY A FUSED FILAMENT FABRICATION (FFF) PROCESS
(FR) PROCÉDÉ DE PRODUCTION D'UN CORPS VERT TRIDIMENSIONNEL PAR UN PROCÉDÉ DE DÉPÔT DE FIL FONDU (FFF)
Abstract:
(EN) The invention relates to a process for producing a three-dimensional green body by a fused filament fabrication process employing at least one filament, which comprises a core material (CM) coated with a layer of a shell material (SM), and a three- dimensional extrusion printer (3D printer). The three-dimensional extrusion printer 0contains at least one nozzle and at least one mixing element. The invention further relates to three-dimensional objects and an extruded strand obtained by the process.
(FR) La présente invention concerne un procédé de production d'un corps vert tridimensionnel par un procédé de dépôt de fil fondu utilisant au moins un fil, qui comprend un matériau de cœur (CM) revêtu d'une couche d'un matériau de coque (SM), et une imprimante tridimensionnelle à extrusion (imprimante 3D). L'imprimante tridimensionnelle à extrusion contient au moins une buse et au moins un élément mélangeur. La présente invention concerne en outre des objets tridimensionnels et un brin extrudé obtenu par le procédé.
