Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and in particular to a texture replication production process and a production device based on 3D printing. Background Art

[0002] In today's glass processing industry, the appearance glass process with texture embossing technology as the technical support is basically finalized and often adopts traditional processes. The glass substrates are mainly ordinary glass, frosted glass, and ultra-thin glass. Processing textures on glass substrates is a routine operation. In addition, in today's rapidly developing era, product innovation is a top priority. In addition to glass printing and UV resin processing, coating is also an innovative way of glass processing. On this basis, coated glass with texture superposition is a new direction; based on the traditional coating process, the current coated glass has no texture pattern, so this increases the cost of purchasing coated glass.

[0003] Whether it is for ordinary glass substrates or coated glass, the processed texture is too single, and the processing effect of the glass surface is also relatively ordinary, which cannot quickly meet the diversified needs. Therefore, this plan proposes a glass texture reproduction production process and production device based on 3D printing, and explores how to solve the technical problem of combining 3D printing technology with mold texture to carry out diversified processing of glass plate surfaces. Summary of the invention

[0009] Step S4: Use universal wear-resistant protective primer ink and universal platinum ink to mix into metallic color, print on the air side of the glass, and undergo a 150-180° baking and curing process.
