Abstract

A thermoplastic material used for three-dimensional printing is disclosed. The thermoplastic material comprises inorganic powder and thermostatic resin. The weight of the inorganic powder is 60-99.9% of the total weight. The weight of the thermostatic resin is 0.1-40% of the total weight. The inorganic powder is ceramic powder or metal powder or ceramic-metal composite powder. An application method of the thermostatic material is also disclosed. The thermoplastic material and the application method provide more printing material choices for the three-dimensional printing technology, and achieve preparation of a three-dimensional structure of a ceramic material, a metal material, or ceramic-metal composites by utilization of the fused deposition modeling three-dimensional printing technology.

Description

technical field [0001] The invention belongs to the field of three-dimensional printing manufacturing, and in particular relates to a thermoplastic material for three-dimensional printing and an application method thereof. Background technique [0002] Three-dimensional printing technology has developed rapidly in recent years and has become a research hotspot. Its principle is to create three-dimensional objects through continuous physical layers. The preparation process of the entity has the characteristics of high precision and fast speed. Its biggest feature is that it can be completed in one step from design to molding, and it can prepare products with more precise and complex structures. Therefore, 3D printing technology has rapidly become a research hotspot since it came out, and its application scope has also rapidly expanded to many industries such as product prototype design, precision parts, architectural models, medical operations, and artworks, and has rapidly d...
