NOVELTY - Forming electrically conductive deposition material extrudable in fluid state involves pre-mixing a polymer component and an extrudability component to produce a pre-mixed mixture; melting the pre-mixed mixture to produce a melted composition; mixing a filler component and the melted composition to produce a melted mixture; and extruding the melted mixture to produce the deposition material. The deposition material comprises 30-99.85 wt.% polymer component, 0.05-10 wt.% extrudability component, and 0.1-60 wt.% filler component. USE - Forming electrically conductive deposition material extrudable in fluid state for deposition via additive manufacturing system and forming three-dimensional (3D) object. ADVANTAGE - The method limit and/or make infeasible the use of high temperature polymer-filler compositions to form high temperature/high strength and/or electrically conductive production portions using additive manufacturing methods such as 3D printing. DETAILED DESCRIPTION - Forming electrically conductive deposition material extrudable in fluid state involves pre-mixing a polymer component and an extrudability component to produce a pre-mixed mixture; melting the pre-mixed mixture to produce a melted composition; mixing a filler component and the melted composition to produce a melted mixture; and extruding the melted mixture to produce the deposition material. The deposition material comprises 30-99.85 wt.% polymer component, 0.05-10 wt.% extrudability component, and 0.1-60 wt.% filler component. The polymer component comprises high temperature polymer; filler component comprises strengthening component and conductive component; extrudability component comprises rheological component and dispersion component; rheological component is polyhedral oligomeric silsesquioxane (POSS); and dispersion component is a silane compound such that, in the fluid state. The deposition material is characterized by the filler component uniformly distributed in the polymer component and electrically conductive deposition material has an electrical resistance of from 1\asterisk10^1 ohms to 1\asterisk10^4 ohms. An INDEPENDENT CLAIM is included for a Method of forming a three-dimensional (3D) object formed from an electrically conductive deposition material extrudable in a fluid state for deposition via an additive manufacturing system, involves (1) Heating the deposition material to a fluid state; (2) Selectively depositing layers of the deposition material in the fluid state onto a substrate to produce a layered material; and (3) Solidifying the layered material to form a three-dimensional (3D) object.
