Antibacterial 3D printing product with microporous structure, and preparation method thereof

Abstract

The invention discloses an antibacterial 3D printing product with a microporous structure, and a preparation method thereof. The 3D printing material is prepared from the following components, by weight: 120-140 parts of ABS, 2-8 parts of a light diffusing agent, 2-8 parts of an initiator, 10-20 parts of a cross-linking agent, 10-20 parts of a coupling agent, 10-30 parts of oyster shell powder, 2-8 parts of bentonite, 1-4 parts of medical stone powder, 1-4 parts of supermicron walnut shell powder, 1-6 parts of limonene, 4-20 parts of a plant antibiotic, 2-8 parts of a stevia extract and 0.2-0.4 parts of an auxiliary agent. The invention provides the novel variety of 3D printing product for users to choose according to needs. In the aspect of 3D printing, the application development space of 3D printing products with ABS as a main raw material is greatly expanded. The product and the method have an important significance.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a 3D printing product and a preparation method thereof. Background technique [0002] With the rapid development of 3D printing technology, the concept of 3D printing is gradually known to the public. FDM technology uses ABS, polycarbonate (PC), polyphenylsulfone (PPSF), PLA and other thermoplastic materials to be heated and extruded into semi-molten filaments, which are deposited on a layer-by-layer basis and constructed directly from 3D CAD data prototype. This technique is commonly used in prototyping, assembly, functional testing and conceptual design. In addition, FDM technology can be applied to proofing and rapid manufacturing. [0003] ABS material, ABS, formerly known as acrylonitrile-butadiene-styrene copolymer, is the main core of household fused deposition (FDM) type wire. In terms of the nature of the material, ABS plastic is fairly easy to print from a hot...

Problems solved by technology

However, on the one hand, the smell of this material is very uncomfortable when printing. On the other hand, the printed products have limited functions and cannot meet the diverse needs of the market.

[0004] With the development of science and technology and social progress, 3D printing products are not limited to industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns and other fields, but also It has begun to enter people's daily life to make some living utensils or decorations, but the current application in life is still reflected in the use of the shape of the printed product, as well as the artistic design formed by its color and shape, etc. , there is still a lot of room for the application and development of 3D printing, and at the same time, the degradability, toughness and strength need to be further improved
