▎ 摘  要

NOVELTY - Composite material for three dimensional printing guitar comprises 66.5-71 pts. wt. regenerated acrylonitrile butadiene styrene (ABS), 18-22 pts. wt. composite carrier, and 1-1.5 pts. wt. other additives. USE - The composite material is useful for three dimensional printing guitar (claimed). ADVANTAGE - The material has excellent mechanical properties, oxidation resistance, shrinkage resistance and warpage resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing composite material, comprising (a) adding regenerated ABS, composite carrier, and other additives into mixer, heating, stirring, and cooling to room temperature to obtain a mixture, and (b) adding mixture to twin-screw extruder for kneading, extruding, cooling, and drying to obtain composite material.
