Abstract: A method of additive manufacturing an article in the ZX (upright) orientation utilizes a composition including specific amounts of a polycarbonate-polysiloxane and polysiloxane-treated titanium dioxide particles. Although addition of titanium dioxide particles to a plastic composition typically reduces impact strength, articles additively manufactured from this composition exhibit improved impact strength relative to articles manufactured from a corresponding composition lacking the polysiloxane-treated titanium dioxide particles.
