The invention relates to a low-temperature low-warpage ASA 3D printing wire and a preparation method thereof. According to mass ratio, 55–70 parts of ASA resin is used as raw material, added with 20–35 parts of elastomer-aramid pulp composite, 3–12 parts of compatibilizer, 3–8 parts of tackifier, 0.2–1 part of antioxidant and 0.2–1 part of paraffin oil. The low-temperature low-warpage ASA 3D printing wire is prepared through drying and dehumidification, material mixing, melt blending, extrusion shaping and traction winding. The wire forms without shrinkage and warpage at a low bottom plate temperature, and has excellent mechanical properties, good bonding performance and outstanding weather resistance, with a wide range of applications and high application value.
