Abstract

La présente invention concerne une poudre de polymère adaptée à l’impression 3D par frittage. Plus particulièrement, la présente invention concerne une poudre comprenant une composition de polymère thermoplastique (composante (a)) particulière, permettant d’obtenir des articles fabriqués par impression 3D à partir de celle-ci ayant une propriété mécanique améliorée. L’invention concerne également son procédé de fabrication et son utilisation pour la fabrication des articles par impression 3D (appelés aussi « pièces imprimées »).The present invention relates to a polymer powder suitable for 3D printing by sintering. More particularly, the present invention relates to a powder comprising a particular thermoplastic polymer composition (component (a)), making it possible to obtain articles manufactured by 3D printing therefrom having an improved mechanical property. The invention also relates to its manufacturing method and its use for manufacturing the articles by 3D printing (also called "printed parts").
