CA 2717677
Powder compositions and articles and methods of forming articles from powder compositions are provided. The powder compositions include at least one powder that preferably includes an amount of one or more branched polymers such as, for example, one or more branched polyamide polymers. The powder composition is preferably capable of being formed, via a layer-by- layer sintering process such as, for example, selective laser sintering, into a three-dimensional article.
La présente invention concerne des compositions pulvérulentes et des objets et des procédés de formation dobjets à partir des compositions pulvérulentes. Les compositions pulvérulentes comprennent au moins une poudre qui comprend de préférence une quantité dun ou de plusieurs polymères ramifiés tels que, par exemple, un ou plusieurs polymères de polyamide ramifiés. La composition pulvérulente est de préférence capable de prendre la forme, au moyen dun procédé de frittage couche par couche tel que, par exemple, un frittage laser sélectif, dun objet tridimensionnel.
