Title
(EN) PROCESSES FOR MAKING 3-D OBJECTS FROM BLENDS OF POLYETHYLENE AND POLAR POLYMERS
(FR) PROCÉDÉS DE FABRICATION D’OBJETS 3D À PARTIR DE MÉLANGES DE POLYÉTHYLÈNE ET DE POLYMÈRES POLAIRES
Abstract
(EN) This invention relates to a process for making a three-dimensional object using an additive manufacturing process. A blend is prepared that includes polyethylene having a density of at least 0.94 g/cm3 and a polar polymer. The blend is extruded to make a filament. The filament can be inserted into an additive manufacturing apparatus that has a nozzle. The filament can be heated. A fluid bead of the filament is dispensed out of the nozzle to manufacture a three- dimensional object.
(FR) La présente invention concerne un procédé de fabrication d’un objet tridimensionnel faisant appel à un procédé de fabrication additive. Un mélange est préparé, lequel comprend du polyéthylène ayant une densité d'au moins 0,94 g/cm3 et un polymère polaire. Le mélange est extrudé pour former un filament. Le filament peut être inséré dans un appareil de fabrication additive présentant une buse. Le filament peut être chauffé. Un cordon fluide du filament sort par la buse pour fabriquer un objet tridimensionnel.
