Title (EN) BIOCOMPATIBLE POLYMER POWDERS FOR ADDITIVE MANUFACTURING
(FR) POUDRES DE POLYMÈRE BIOCOMPATIBLE POUR FABRICATION ADDITIVE
Abstract:
(EN) The present invention is directed to biocompatible polymeric powders to be used for 3D printing applications. More specifically, the 3D printing process will allow a tool less manufacturing of medical devices in particular in the implantables or regenerative space. Its flow and other processing characteristics qualifies them for the use in selective laser sintering, but also could be suitable for other powder based 3D printing technologies.
(FR) La présente invention concerne des poudres polymères biocompatibles destinées à être utilisées pour des applications d'impression 3D. Plus spécifiquement, le procédé d'impression 3D permettra de fabriquer sans outil des dispositifs médicaux, en particulier dans le domaine des implants ou en médecine régénérative. Leurs caractéristiques d'écoulement et de traitement autres les qualifient pour l'utilisation dans le frittage laser sélectif, mais pourraient également convenir à d'autres technologies d'impression 3D à base de poudre.
