Problems solved by technology

[0005] Among them, ABS resin is the earliest material used in fused deposition modeling (FDM) technology. The printing temperature of this material is 210-260°C, and the glass transition temperature is 105°C. It has many advantages, such as high strength and good toughness. , impact resistance, insulation, corrosion resistance, and low temperature resistance. However, ABS needs to be heated when printing. At the same time, the material shrinks significantly when it is cold, and it is prone to quality problems such as warping and cracking.

Abstract

The invention provides a modified ABS material doped by carbon fiber nanoflakes and used for 3D printing, and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing dried SBS and ABS with a surfactant; and then adding glass fibers and carbon fiber nanoflakes, carrying out mixing and heating, and then carrying out screw extrusion and drying so as to obtain the modified ABS material. The modified ABS material for 3D printing in the invention is not prone to warping and cracking and has substantially improved cold contractility.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a modified ABS material for 3D printing of carbon-doped fiber nanosheets 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, ...
