Method for improving surface light transparency of 3D printing transparent material

Abstract

The invention provides a method for improving the light transmittance of the surface of 3D printing transparent materials, which belongs to the technical field of transparent application of 3D printing objects. At normal temperature, the volume ratio of epoxy resin crystal glue and curing agent crystal glue is 2.5~3.5:1 mixing, stirring until the colorless transparent viscous mixed solution; evenly apply the mixed solution obtained in step (1) on the surface of the 3D printed object, the coating thickness is 1mm~3mm; wherein, the 3D printed object Made of transparent material; curing: place the 3D printed object coated in step (2) at a temperature of 60-70°C, and cure for 16-24 minutes, so that the mixed solution is cured on the surface of the 3D printed object. The curable material of the present invention is heated at a high temperature, thereby increasing the coagulation rate and improving the production and processing efficiency. The invention has simple process steps, high processing speed and low cost of raw materials, and is suitable for popularization.

Problems solved by technology

Among them, the demand for highly transparent materials in the medical field, jewelry, and industrial manufacturing is gradually increasing, such as the application of medical aided cognitive fusion in prostate biopsy, the preparation of transparent conductive electrodes, etc., but the existing 3D printing technology is difficult to meet this demand

Existing 3D printing materials mostly use chemical polymers, and the surface smoothness of the molded product model is not good, which affects the visual transparency of the product

Polishing is currently a more commonly used post-grinding method, but the accuracy and shape of the printed object have brought difficulties and restrictions to polishing

Therefore, although 3D printing materials with better transparency have been developed, it is difficult for the existing low-end 3D printing equipment on the market to produce finished products with ideal transparency. Generally, post-polishing is required to improve the transparency of finished products

However, the polishing and grinding technology is complex and difficult to deal with small or deep internal groove structures. Therefore, more convenient post-processing technology is urgently needed to improve the transparency of 3D printed products.
