  • Publication number: 20220389262
    Abstract: The invention relates to an additive-manufacture feedstock, comprising an ethylene-vinyl ester polymer having a melt flow rate of from 0.1 to 150 g/10 min (190° C./2.16 kg), measured according to ASTM D 1238, and a vinyl ester content of from about 1.0 wt % to about 30 wt %, wherein the ethylene-vinyl ester polymer exhibits a Shore A hardness of at least about 60. The pellets and filaments produced from the additive-manufacture feedstock have a high degree of printability in material-extrusion-based 3D printing technology, and can be used to produce 3D printing articles with a high consistency to the targeted 3D model and substantially no warpage. The invention also relates to methods of making the additive-manufacture feedstock and methods of 3D printing using the additive-manufacture feedstock in various forms.
