Problems solved by technology

These materials not only have high hardness, the printed parts are brittle and fragile, but also require high printing conditions, and often cannot print tiny structures with high definition
The Chinese invention patent with the patent number ZL201010530017.X reports a method for preparing a material for rapid prototyping of 3D printing. Although the rapid prototyping material has been modified by surface dispersion, not only the molding accuracy is not high, but the details of the parts are not clear. Moreover, it is brittle after bonding and is easily damaged

Abstract

The invention discloses a three-dimensional printing forming material with toughness and high adhesive property. The three-dimensional printing forming material comprises a powder material and an adhesive material and is characterized in that the powder material comprises the following components in parts by weight: 40-85 parts of polyamide resin, 5-40 parts of pigments, 5-30 parts of filler, 1-6 parts of pigment and filler dispersing and wetting aid, 0.1-1.5 parts of flatting agent and 0.1-0.5 part of degassing agent; the adhesive material comprises the following components in parts by weight: 60-95 parts of epoxy resin, 5-40 parts of filler, 1-10 parts of toughening agent, 0.1-1.5 parts of flatting agent, 1-4 parts of pigment and filler dispersing and wetting aid, 0.1-0.5 part of degassing agent and 0.1-0.5 parts of powder flowing aid; and when the three-dimensional printing forming material is used, 1 part by weight of powder material and 0.01-0.5 part by weight of adhesive material are cooperatively used. A solid component printed by using the material disclosed by the invention has the advantages of higher adhesion strength and firmness, good flexibility and scratching resistance.

Description

technical field [0001] The invention relates to the field of 3D printing molding materials, in particular to a tough and highly cohesive 3D printing molding material and a preparation method thereof. Background technique [0002] 3D printing technology (Three Dimensions Printing, 3D printing technology, 3DP) is a form of additive manufacturing (AM) technology, and its principle is to create physical objects by adding materials to objects layer by layer. Stacked manufacturing technology was first standardized by ASTM International (formerly known as the American Society for Testing and Materials), but stacked manufacturing technology has 3 different terms: stereolithography (Stereolithography), three-dimensional stacked manufacturing (3-Dlayering) and 3D printing; where 3D printing is gradually becoming the most commonly used term as it best describes the additive manufacturing technology and its products. [0003] The principle of 3D printing technology is similar to the fo...
