Chinese invention patent "Preparation method of a rapid prototyping material for three-dimensional printing" (CN102093646A) discloses a preparation method of a rapid prototyping material for three-dimensional printing, but its powder material and the main components of the bonding solution are both It is an organic resin, its production process is relatively complicated, the cost is high, and it is not suitable for the preparation of human medical implant materials
In addition, the Chinese invention patent "A Highly Tough and Highly Cohesive 3D Printing Molding Material and Its Preparation Method" (CN103205107A) discloses a molding material and its preparation method. The bond strength of solid parts printed with this material is , firmness, good flexibility, scratch resistance and other properties are ideal, but because the adhesive uses a high-temperature thermal spray system, the production cost is very high, and it is only suitable for printing medical implant materials with very high quality requirements

Abstract

The invention discloses a polymer powder for 3D printing and a preparation method of the polymer powder. The polymer powder comprises the following substances in parts by weight: 30-90 parts of main body molding resin, 10-60 parts of bonding resin, 0-10 parts of composite resin and 0-10 parts of powder leveling agent. The preparation method for preparing the powder comprises: blending the substances at room temperature and then sufficiently stirring till the substances are evenly mixed. The powder can be used for printing human body medical implant materials with good flexibility and medical appliances; when the powder is used for 3D printing, only deionized water is used as bonding solution, so that the process is simple and the cost is low; therefore, the 3D printing environment is environmental friendly and can meet a modern green manufacturing direction.

Description

【Technical field】 [0001] The invention relates to the field of 3D printing molding materials, more specifically a polymer powder for 3D printing and a preparation method thereof. 【Background technique】 [0002] 3D printing (three-dimensional printing, ThreeDimensionalPrinting) technology is a rapid prototyping technology with the fastest development speed and the greatest development potential. It has the advantages of low cost, simple process, quick use, and diversity. Preparation of medical devices, automobile industry, etc. At present, the most commonly used 3D printing system is based on jet printing technology. The bonding solution is sprayed out in a dot matrix through the piezoelectric nozzle according to the design data, and the powder material is bonded into a two-dimensional cross-section, and this process is repeated back and forth. Finally, The various sections are bonded and superimposed layer by layer to obtain the required complete three-dimensional solid pro...
