Abstract
An acrylic alloy composition that can be 3-D printed by a material extrusion additive manufacturing process, an acrylic filament that has a very uniform diameter useful in the extrusion additive manufacturing process, acrylic articles made from the acrylic alloy composition by a material extrusion additive process, and a material extrusion additive manufacturing process for producing the acrylic articles. The acrylic alloy composition is an alloy of an acrylic polymer, and a low melt viscosity polymer, such as polylactic acid. The alloy may optionally be impact modified, preferably with hard core core-shell impact modifiers.
