Abstract

The invention relates to the field of a plastic cement raw material, in particular to a modified ABS material for a 3D printing machine and a preparation method thereof. The modified ABS material forthe 3D printing machine is prepared from the following ingredients in percentage by mass: 60 to 90 percent of ABS, 10 to 40 percent of ASA, 0.1 to 0.5 percent of antioxidants, 0.1 to 0.5 percent of lubricants and 0.3 to 0.8 percent of surfactants. The modified ABS material for the 3D printing machine has the advantages that the thermal stability is high; the physical performance is good; the weather-resistant performance is good.

Description

technical field [0001] The invention relates to the field of plastic raw materials, in particular to a modified ABS material for a 3D printer and a preparation method thereof. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. ...
