| description | The present in invention relates to powder mixtures for use in additive manufacture, which comprise three particle fractions A, B and C with different median particle sizes, wherein the median particle sizes relate to each other as 0.2 to 0.5 / 1 / 1.2 to 2. These powder mixtures have higher apparent density and/or conditioned bulk density compared to conventional additive manufacture powders and thus allow for faster processing with less defects. The present invention further relates to methods for the preparation of respective powder mixtures, methods and devices for the preparation of three-dimensional objects from such powder mixtures and three-dimensional objects, which have been prepared accordingly, as well as the use of the powder mixtures for reducing the amount of defects in additive manufacturing processes.
La présente invention concerne des mélanges de poudres destinés à être utilisés dans la fabrication additive, comprenant trois fractions de particules A, B et C présentant des tailles médianes de particules différentes, les tailles médianes de particules se rapportant entre elles de 0,2 à 0,5 / 1 / 1,2 à 2. Lesdits mélanges de poudres présentent une masse volumique apparente et/ou une masse volumique en vrac conditionnée plus élevée que les poudres de fabrication additive conventionnelles et permettent donc un traitement plus rapide avec moins de défauts. La présente invention concerne également des procédés de préparation de mélanges de poudres respectifs, des procédés et des dispositifs de préparation d'objets tridimensionnels à partir de tels mélanges de poudres et d'objets tridimensionnels préparés en conséquence, ainsi que l'utilisation des mélanges de poudres pour réduire la quantité de défauts dans les processus de fabrication additive. |
