Abstract: A method of fused filament fabrication (FFF) additive manufacturing comprises employing an olefin block copolymer. The method allows for the additive manufacturing article that retains the desirable mechanical properties of polyolefins such as polyethylene or polypropylene without experiencing the problems inherent in FFF printing of polyethylene or polypropylene particularly in the absence of solid fillers. In a particular embodiment, the additive manufactured article is comprised of the olefin block copolymer is comprised of block composite or crystalline block composite polymer or mixture thereof comprising the olefin block copolymer, wherein the olefin block copolymer is comprised of an isotactic propylene block and a polyethylene rich block.
