Beschreibung
Zusammenfassung:	According to some examples, a method of forming a three-dimensional article includes contacting a substrate with a first quantity of a powder composition. The powder composition includes an amorphous thermoplastic component. The powder composition further includes a semi-crystalline thermoplastic component. The method further includes fusing at least a portion the first quantity of the powder composition to form a first layer. The amorphous thermoplastic component and the semi-crystalline thermoplastic component are substantially free of phase separation when combined in a melt state. Selon certains exemples, l'invention concerne un procédé de formation d'un article tridimensionnel comprenant la mise en contact d'un substrat avec une première quantité d'une composition de poudre. La composition de poudre comprend un composant thermoplastique amorphe. La composition de poudre comprend en outre un composant thermoplastique semi-cristallin. Le procédé comprend en outre la fusion d'au moins une partie de la première quantité de la composition de poudre pour former une première couche. Le composant thermoplastique amorphe et le composant thermoplastique semi-cristallin ne comprennent sensiblement pas de séparation de phase lorsqu'ils sont combinés dans un état fondu.
