Abstract

The invention relates to the technical field of 3D printing materials, and specifically relates to an ABS composite material used for 3D printing. The ABS composite material used for 3D printing is prepared from the following raw materials in parts by weight: 70 to 100 parts of ABS plastic, 20 to 40 parts of ASA plastic, 5 to 15 parts of a flexibilizer, 0.5 to 3 parts of a lubricating agent and 0.5 to 5 parts of an anti-aging agent. The ABS composite material used for 3D printing has the characteristics of high strength, high tenacity and good anti-aging performance.

Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to an ABS composite material for 3D printing. Background technique [0002] 3D printing is a technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. With the development of 3D printing technology, it has been widely used in industrial design, engineering, automotive, aerospace, dental and medical fields. [0003] ABS, also known as ABS resin; it is a material with high strength, good toughness, and easy processing; it is one of the commonly used materials for 3D printing. However, the anti-aging performance of ABS materials currently used for printing needs to be further strengthened. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an ABS composite material for 3D printing, and the ABS composite material has go...
