Description

3D printing ink and preparation method thereof
Technical Field
The disclosure relates to the technical field of 3D printing, in particular to 3D printing ink and a preparation method thereof.
Background
3D printing, also known as additive manufacturing, belongs to one of the rapid prototyping technologies, and is a technology (namely 'lamination technology') for constructing an object in a layer-by-layer stacking and accumulating manner on the basis of a digital model file by taking a bondable material such as powdered metal or plastic as a base material. The 3D printing is a manufacturing process of accumulating materials from top to bottom, has obvious advantages of low manufacturing cost, short production period and the like, is known as a production tool with the most marking property in the third industrial revolution, namely 3D printing, also called additive manufacturing, and belongs to a rapid prototyping technology. 3D printing is a manufacturing process for accumulating materials from top to bottom, has the obvious advantages of low manufacturing cost, short production period and the like, and is known as a production tool which has the most marking property in the third industrial revolution. In recent years, with the temperature rise of the industry, 3D printing has raised a new wave in the world, and meanwhile, the 3D printing technology is widely applied to the fields of automobile manufacturing, aerospace, teaching and scientific research, health and medical care, building, entertainment and the like at present, and realizes innovative breakthrough in various fields, and is generally regarded by the manufacturing industry and various users.
3D printing has been a long-term development in the polymer processing field and has found important applications in many fields. The nylon, polylactic acid, ABS and other resins can be processed and molded in a 3D printing mode. In addition, the composite material prepared by the polymer and graphene, carbon nanotubes or clay can also be formed by 3D printing. However, despite the rapid development of 3D printing processing techniques for polymers, the mass production of polymer materials using 3D printing techniques still faces many challenges. One of the biggest challenges is that there are few and often expensive varieties of polymers that can be used for 3D printing technology modeling that have practical application value. The technology that ordinary engineering polymers can be applied to 3D printing processing through simple treatment processes has important significance for 3D printing technology and even the whole processing industry.
However, the toughness of common rubber materials is mostly poor, the molding shrinkage rate is large, and the 3D printing process is easy to shrink and deform to cause warping, so that the precision and the performance of products are affected.
