Embodiment 1

[0020] 1. Fully stir and mix 50 parts by weight of diatomite, 20 parts by weight of sodium silicate, 5 parts by weight of silicon fluoride, and 50 parts by weight of water to obtain a 3D printing mixture;

[0021] 2. Design a 3D printing three-dimensional structural model in the computer as needed, and import the model into the 3D printer;

[0022] 3. Add the 3D printing mixture obtained in step 1 into the trough of the 3D printer, and put the printing platform of the 3D machine into a low-temperature environment with a temperature of -25°C;

[0023] 4. Start the 3D printer for 3D printing. The print nozzle will accurately control the mixture in the material tank according to the model and spray it on the printing platform. In a low temperature environment, the water in the mixture will quickly condense into ice due to the low temperature, thereby solidifying , repeat the spraying process, so that layers are piled up to form the required product shape, and the first embryo is ...

Abstract

The invention provides a 3D printing forming method of an inorganic material. 3D printing forming is performed on the inorganic material through an indirect forming method, and the principle that liquid-state water fast solidifies and ices under the low-temperature condition is utilized. Firstly, a mixed material formed by mixing the inorganic material and an inorganic adhesion agent is formed through condensation of water, then an adhesive in the formed inorganic adhesion agent reacts with a curing agent, the inorganic material is bonded to form a whole, a primary blank is prepared, finally the product is obtained after unfreezing and drying, the prepared product is good in size precision, the formed shape can be easily controlled, the method is simple and reliable, cost is low, the defects that during 3D printing forming of the inorganic material, forming is difficult and cost is high are overcome, application and popularization of the 3D printing forming technology in life are promoted, and the method has broad market prospects.

Description

technical field [0001] The invention relates to a 3D printing molding method, in particular to a 3D printing molding method of inorganic materials. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is an emerging technology in the field of rapid prototyping. It is based on digital model files and uses bondable materials such as powdered metal or plastic to print layer by layer. Techniques for constructing objects. With the development and application of 3D printing technology, materials have become one of the key factors limiting the future direction of 3D printing technology. To a certain extent, the development of materials determines whether 3D printing can be more widely used. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials, and ceramic materials. The field of printing has been applied. [0003] The development and use of many 3D printin...
