Abstract
A polymer material in manufacture of 3D articles by means of additive manufacturing, the polymer material including: at least one polyethylene 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.-%, at least one solid filler, and at least one nucleating agent, wherein the at least one solid filler is a fibrous filler having a volume-based mean aspect ratio (length/diameter) of 3-60.
