Beschreibung
Zusammenfassung:	The invention relates to an additive-manufacture feedstock, comprising an ethylene polymer blend composition having an ethylene polymer having a melt flow index of from 0.1 to 150 g/10 min (190° C./2.16 kg), measured according to ASTM D 1238, and at least one of the following components blended in the ethylene polymer: a polyolefin elastomer, an ethylene-vinyl ester polymer, a fiber, a nucleator or clarifier, or a polypropylene polymer. The additive-manufacture feedstock, when in the form of a printed article, exhibits an improved printability characterized by an improved warpage-resistance rating. The invention also relates to methods of making the additive-manufacture feedstock and methods of 3D printing or additive manufacturing using the additive-manufacture feedstock in various forms.
