Beschreibung
Zusammenfassung:	The present invention relates to a process for manufacturing a three-dimensional (3D) article, part or composite material, from a filament comprising a polyamide (PA) presenting 4,4'-diaminodicyclohexylmethane moieties, as well as to such filament. The present invention also relates to the 3D article, part or composite material 5 obtainable from such process, as well as the use of the article, part or composite materials in oil and gas applications, automotive applications, electric and electronic applications, aerospace, medical and consumer goods. La présente invention concerne un procédé de fabrication d'un article, d'une pièce ou de matériau composite tridimensionnel (3D), à partir d'un filament comprenant un polyamide (PA) présentant des fractions 4,4'diaminodicyclohexylméthane, ainsi qu'un tel filament. La présente invention se rapporte également à l'article, la pièce ou le matériau composite 3D, pouvant être obtenu par l'intermédiaire d'un tel procédé, ainsi qu'à l'utilisation de l'article, de la pièce ou des matériaux composites dans des applications pétrolières et gazières, des applications automobiles, des applications électriques et électroniques, des applications aérospatiales, médicales et relatives aux biens de consommation.
