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 a polyethylene and a cyclic-olefin copolymer. The blend is extruded to make a filament. The filament can be inserted into an additive manufacturing apparatus with a nozzle. The filament can be heated. A fluid bead of the filament can be 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 comprenant un polyéthylène et un copolymère de cyclooléfine est préparé. 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 peut sortir de la buse pour fabriquer un objet tridimensionnel.
