Zusammenfassung:	Use of a polymer material in manufacture of 3D articles by means of additive manufacturing, the polymer material comprising: a) At least one polyethylene PE having a density at 23 °C determined according to EN ISO 1183-1 :2019 standard of at least 0.930 kg/m3 and a crystallinity determined according to EN ISO 11357-3:2018 standard of at least 50 wt.-%, b) At least one solid filler F, and c) Optionally at least one nucleating agent N, wherein the at least one solid filler F is a fibrous filler having a volume-based mean aspect ratio (length/diameter) of 3 - 60, preferably 4 - 50. Utilisation d'un matériau polymère dans la fabrication d'articles 3D par fabrication additive, le matériau polymère comprenant : a) au moins un polyéthylène PE ayant une masse volumique à 23 °C, déterminée selon la norme EN ISO 1183-1:2019 d'au moins 0,930 kg/m3 et une cristallinité déterminée selon la norme EN ISO 11357-3:2018 d'au moins 50 % en poids, b) au moins une charge solide F et c) éventuellement, au moins un agent de nucléation N, l'au moins une charge solide F étant une charge fibreuse ayant un rapport d'aspect moyen en volume (longueur/diamètre) de 3 à 60, de préférence de 4 à 50.
