Abstract

The invention discloses an antibacterial 3D printing line and a preparation method thereof. The preparation method comprises the following steps: mixing a water-based epoxy resin, silver nitrate and water, filtering, and drying to obtain an antibacterial resin; mixing an acrylonitrile-butadiene-styrene plastic, the antibacterial resin, a polyamide resin, vermiculite powder, barium stearate, aluminum powder, glass fibers, an initiator, a crosslinking agent and a pigment, and melting to form a molten liquid M; and carrying out wire drawing formation on the molten liquid M to obtain the antibacterial 3D printing line. The method solves the following problems: nonuniform shrinkage of the common line caused by different cooling rates can easily result in warping of the formed line; and the surface of the printing material can easily become moldy since the printing material is stored in a humid environment for a long time.

Description

technical field [0001] The invention relates to a 3D printing material, in particular to a bacteriostatic 3D printing wire and a preparation method thereof. Background technique [0002] 3D printing materials are an important material basis for the development of 3D printing technology. To a certain extent, the development of materials determines whether 3D printing can be used more widely. At present, 3D printing materials mainly include engineering plastics, vermiculite powder, and rubber materials. , metal materials and ceramic materials. Ordinary wire rods cause uneven shrinkage due to different cooling rates, which can easily lead to warping of the wire rod after molding and affect the quality of the molded product. At the same time, the printed material is stored in a humid environment for a long time, and its surface is prone to mold and plaque. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a bacteriostatic 3D printing w...
