Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an ABS consumable for 3D printing and a preparation method thereof. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. It has been used in jewelry, There are applications in footwear, industrial design, architecture, engineering, automotive, aerospace and more. [0003] ABS is an acrylonitrile-butadiene-styrene-terpolymer, which has the advantages of heat resistance and corrosion resistance of acrylonitrile, the impact resistance of butadiene and the rigidity of styrene, and is an excellent comprehensive performance. Heat-shrinkable materials, but pure ABS resin still has disadvantages such as poor toughness and insufficient processing flow, so it must be modified. ...
