Current variable elastomer material for 3D printing and preparation method thereof

Abstract

The invention relates to a current variable elastomer material for 3D printing and a preparation method thereof, and belongs to the field of a 3D printing material. The preparation method of the current variable elastomer material for 3D printing comprises the following preparation steps that a, after liquid-state silicon rubber and a cross-linking agent are uniformly mixed, the mixture is put into a freezing pulverization machine; through freezing pulverization, silicone rubber particles are obtained; the silicone rubber particles, starch and silicone oil are mixed; the temperature is raisedto 50 to 80 DEG C; stirring is performed for 1 to 4h to obtain starch silicone rubber; b, the starch silicone rubber is added into swollen cellulose ether; then, plaster and an antifoaming agent are added; after the mixture is uniformly ground by a ball grinding machine, the pasty 3D printing material containing a current variable elastomer is prepared. Compared with the current variable liquid for 3D printing, the prepared current variable elastomer material for 3D printing has the advantages that the defect that the printing product precision is influenced since the liquid state cannot be precisely controlled is overcome; the printing precision is higher.

Description

technical field [0001] The invention relates to an electrorheological elastomer material for 3D printing and a preparation method thereof, belonging to the field of 3D printing materials. Background technique [0002] Additive Manufacturing technology (Additive Manufacturing), also known as rapid prototyping technology, three-dimensional printing technology, the popular name is 3D printing manufacturing technology. It is an advanced manufacturing technology developed through the multidisciplinary integration of information technology, new material technology and high-end manufacturing technology in the past 20 years. 3D printing manufacturing technology is a rapid additive manufacturing technology that generates three-dimensional entities by increasing the accumulation of materials layer by layer. It not only overcomes the loss caused by traditional subtractive manufacturing, but also makes product manufacturing more intelligent, more accurate and more efficient. Especially...

Problems solved by technology

However, when 3D printing is performed with electrorheological fluid, the accuracy of the printed product is affected due to the inability to accurately control the liquid state. At the same time, there is water or solvent in the electrorheological fluid, which is slow to dry and solidify, which affects the printing efficiency.
