Abstract: An additive manufacturing composition useful as a support material for common build materials (e.g., polyamide or polyester) is comprised of a blend of an elastomer toughened styrenic polymer having discreet domains of polymerized conjugate diene dispersed within a styrenic matrix and a vinyl aromatic-maleic anhydride copolymer. The composition may be used as a support material in additive manufacturing methods such as extrusion methods (e.g., fused filament fabrication). The compositions may be tuned to realize the desired adherence to facilitate the desired support while also allowing for the mechanical removal without breakage of the underlying part or residual adhered support material.
