Title (EN) SELECTIVE SINTERING ADDITIVE MANUFACTURING METHOD AND POWDER USED THEREIN
(FR) PROCÉDÉ DE FABRICATION ADDITIVE PAR FRITTAGE SÉLECTIF ET POUDRE UTILISÉE À CET ÉGARD
Abstract:
(EN) A method of selective sintering additive manufacturing comprises employing a powder comprising composite particulates comprising a first thermoplastic polymer and a second thermoplastic polymer interspersed with each other. In a particular embodiment, the first thermoplastic polymer and second thermoplastic polymer have differing absorbance of the irradiation used to sinter the particles when performing the additive manufacturing method. The first and second thermoplastic polymer may be continuously intertwined in within the particles or one of the polymers may be a discontinuously dispersed in a continuous matrix of the other polymer.
(FR) La présente invention concerne un procédé de fabrication additive par frittage sélectif comprenant l'utilisation d'une poudre comprenant des particules composites comprenant un premier polymère thermoplastique et un second polymère thermoplastique intercalés l'un par rapport à l'autre. Selon un mode de réalisation particulier, le premier polymère thermoplastique et le second polymère thermoplastique ont des absorbances différentes de l'irradiation utilisée pour fritter les particules lors de la mise en œuvre du procédé de fabrication additive. Le premier et le second polymère thermoplastique peuvent être entrelacés en continu au sein des particules ou l'un des polymères peut être un dispersé de manière discontinue dans une matrice continue de l'autre polymère.
