Abstract

The invention discloses glue for a 3D (Three-Dimensional) printer and a preparation method thereof. The glue comprises the following components in parts by weight: 55-75 parts of deionized water, 12-18 parts of ethylene glycol, 15-20 parts of isopropanol, 10-13 parts of triethanolamine, 3-6 parts of nonyl phenol polyoxyethylene ether, 3-6 parts of polyvinyl alcohol and 0-5 parts of industrial dye. The preparation method comprises the following steps: stirring; standing; deoxidizing; filtering and the like. The glue disclosed by the invention shortens the curing time of a printed object, and isopropanol enhances dissolution of polyvinyl alcohol, so that the viscidity among layers is enhanced, the tensile strength and hardness of the printed object are enhanced, the hot wind curing and hardening time is shortened, the efficiency is improved and the energy consumption is reduced. The method provided by the invention is simple and strong in operability.

Description

Technical field [0001] The invention relates to the technical field of 3D printing consumables, in particular to a glue for 3D printers and a preparation method thereof. Background technique [0002] 3D printing technology, also known as three-dimensional printing technology, refers to a 3D printer that can "print" real objects, using layered processing and superposition forming to add materials layer by layer to generate 3D entities. The most prominent advantage of 3D printing technology is that it can directly generate objects of any shape from computer graphics data without machining or molds, which greatly shortens the product development cycle, improves productivity and reduces production costs. [0003] The core of the development of 3D printing technology is not printing, but the constraints of material technology. Only with the development of new material technology can 3D printing technology be further practical. At present, 3D printers have been used to make molds, human ...
