Problems solved by technology

[0003] In 3D printing technology, represented by FDM (Fused Deposition Type), there is a defect in printing: the product is easy to warp or even peel off the platform during the printing process; the printed product sticks to the platform and is not easy to remove, which may cause damage to the product cause damage
The Wolfbite Nano adhesive of Airwolf in the United States is a product specially developed for this purpose. Its price is relatively high, and it is mainly used for printing on PLA materials, and it needs to be coated on the surface of the platform, which is troublesome.

Abstract

The invention discloses an adhesive tape specially used for three-dimensional (3D) printing. The adhesive tape consists of an adhesive A coating layer, a base material, an adhesive B coating layer and release paper, wherein the two surfaces of the base material are firstly and respectively coated with adhesive A and adhesive B; the thickness of the adhesive A coating layer is 0.075-0.25mm, and the thickness of the adhesive B coating layer is 0.05-0.20mm; the release paper covers one side of the adhesive A coating layer. The adhesive tape provided by the invention has high temperature resistance; after the adhesive tape is stuck on a 3D printer platform and the printer platform is heated, a print product is firmly stuck on the printer platform, so that the phenomena of warping and even stripping can be avoided. When the printer platform is cooled, the adhesion degree of an upper surface bonding layer is reduced, so that the product can easily get away from the platform. After the adhesive tape is used, no adhesive residue exists on the surface of the product; furthermore, the adhesive tape can be repeatedly used for a plurality of times.

Description

technical field [0001] The invention relates to a special adhesive tape for 3D printing. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] 3D printing technology is represented by FDM (Fused Deposition Type), and there is a defect in printing: the product is easy to warp or even peel off the platform during the printing process; after printing, the product sticks to the platform and is not easy to remove, which may cause damage to the product when it is removed. cause damage. [0004] At present, there are few solutions to this problem. Most of them use 3M high-temperature-resistant masking paper to paste on the platform to solve the problem of warping or peeling off, but the effect is not good, and it aggravates the problem that the product is not easy to remove. It...
