Abstract

The invention relates to a 3D (three-dimensional) printing material, which comprises powered ink and a bonder, wherein the powdered ink comprises 100 parts by weight of polyamide, 50 to 80 parts by weight of oxidized starch, 10 to 30 parts by weight of rosin resin, 5 to 80 parts by weight of pigment, 5 to 30 parts by weight of filler and 0.1 to 0.5 part by weight of degassing agent; the bonder comprises 100 parts by weight of epoxy resin, 10 to 30 parts by weight of rosin resin, 5 to 30 parts by weight of filler, 0.1 to 1.5 parts by weight of leveling agent and 0.1 to 0.5 part by weight of degassing agent. According to the 3D printing material, the thermoplastic oxidized starch is adopted, and can be well bonded with the epoxy resin, so that the bonding power between the powdered ink and the bonder is improved, and a solid part with high bonding strength and high firmness is favorably obtained.

Description

[0001] technical field [0002] The invention relates to a 3D printing material. Background technique [0003] 3D printing is a form of additive manufacturing that works by adding material to an object in layers to create a physical object. [0004] The current 3D printing molding materials are mainly thermoplastic materials such as polyethylene terephthalate, polybutylene terephthalate, polyarylate, and acrylonitrile-butadiene-styrene. 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. Contents of the invention [0005] The object of the present invention is to overcome the defects of the above-mentioned prior art, and provide a 3D printing material with high bonding strength and firmness of printed solid parts. [0006] To achieve the above object, the present invention adopts the following technical solutions: [0007] A 3D prin...
