3D printing material and preparation method thereof

Abstract

The invention discloses a 3D printing material and a preparation method thereof. The 3D printing material is formed by the following formula components by mass: 10-20 parts of graphite powder, 2-4 parts of a catalyst, 6-8 parts of polyether polyol, 2-3 parts of vinyl triethoxy silane, 3-6 parts of inorganic powder, 2-6 parts of nano zirconium dioxide, 13-15 parts of vinyl ester resin, 1-2 parts of food-grade pigment, 6-10 parts of expanded perlite, 10-20 parts of wood fiber, 4-6 parts of isocyanate, 3-5 parts of food-grade synthetic wax, and 1-3 parts of an organic solvent. The prepared 3D printing material is non-toxic, low carbon and environmental, and has the excellent combination property, and the higher economic value and the broad market prospect.

Description

technical field [0001] The invention relates to the field of 3D printing materials, in particular to a 3D printing material and a preparation method thereof. Background technique [0002] PLA and ABS resin are the most commonly used molding materials in 3D printing consumables. People have systematically studied the process parameters such as extrusion speed, wire output speed, extrusion height, scanning height, scanning deposition method, nozzle outlet temperature, and molding room ambient temperature. It affects the density, tensile strength and modulus, bending strength and modulus of molding consumables, as well as the precision and surface finish of the parts. However, with the rapid development of 3D printing technology, new requirements are put forward for 3D printing materials. Requirements, taking melt extrusion molding technology as an example, it is necessary to comprehensively consider the size of the plastic fuse and the molding performance to design the tempera...
