Abstract

The invention discloses a preparation method of a three dimensional printing rapid forming inorganic powder material, and the method is characterized in that: adding 8%-22% by mass of vinyltriethoxysilane and 78%-92% by mass of an inorganic powder material into a grinding machine, starting the grinding machine for grinding for 4-6h in 200 rpm/min speed at room temperature to obtain a preprocessed inorganic powder material; then adding 85%-96% by mass of preprocessed inorganic powder material and 4%-15% of EVA (ethylene vinyl-acetate copolymer) hot melt adhesive powder into the grinding machine, starting the grinding machine for grinding for 4-6h in 200 rpm/min speed at room temperature to obtain the three dimensional printing rapid forming inorganic powder material, The method has the advantages of being simple in preparation process, easy to control, low in production cost, and easy in industrial production. The material can be directly formed by heating at 140 to 180 DEG C and under the pressure in the 2MPa-6MPa range without spraying of an adhesive, and the forming operation is simple.

Description

technical field [0001] The invention relates to a method for preparing a 3D printing inorganic powder rapid prototyping material, which belongs to the field of rapid prototyping materials, and in particular to a preparation process for a 3D printing rapid prototyping inorganic powder material. Background technique [0002] Three Dimonsion Printing (Three Dimonsion Printing, referred to as Three DP) is a rapid prototyping technology, which can divide the three-dimensional model data designed by the computer into layer model data, and build specific raw materials layer by layer until the entire entity is constructed. Three-DP molding has the advantages of low cost, no pollution in the working process, and fast molding speed. [0003] Rapid Prototyping Technology, also known as Rapid Prototyping Manufacturing (RPM) technology, was born in the late 1980s. It is a high-tech manufacturing technology based on the material accumulation method and is considered to be a major achievem...
