Polyolefins having improved dimensional stability in three-dimensional printing, articles formed therefrom, and methods thereof

Abstract

A compounded polymer composition suitable for manufacturing of isotropic three-dimensional printed articles may include an impact copolymer, a low crystalline ethylene/α-olefin copolymer; a nucleating agent; and filler, where the impact copolymer may include a matrix phase comprising a propylene-based polymer or copolymer; and a dispersed phase in the matrix phase, the dispersed phase comprising an ethylene-based copolymer, the ethylene-based copolymer having a C3-C12 comonomer, wherein the dispersed phase has a different composition than the matrix phase.
