AI Technical Summary

Problems solved by technology

However, this solution has the disadvantage of slow curing speed. During printing, the ceramic particles are easily dislocated by external forces before curing. On the one hand, it is easy to cause deformation of the green body, and on the other hand, it will cause the casting structure to be loose. It is difficult to improve the hardness and strength of castings
At the same time, the residual adhesive sometimes blocks the print head after printing, which affects the normal use of the printer.

A rapidly solidified and formed ceramic material comprises a ceramic slurry and an adhesive, wherein the ceramic slurry comprises 75-80 parts of ceramic microspheres, 3-4 parts of metal fibers, 0.1-0.3 parts of a surfactant, 1-2 parts of an auxiliary adhesive and 80-90 parts of water; the adhesive comprises 5-10 parts of vinyl acetate, 6-8 parts of methyl methacrylate, 9-12 parts of butyl acrylate, 5-6 parts of VeoVa, 3-5 parts of dibutyl phthalate and 1-3 parts of polyvinyl alcohol. The invention also provides a 3D printing method of the rapidly solidified and formed ceramic material, wherein the 3D printing method comprises the following steps: constructing a three-dimensional model; conveying the ceramic slurry to a slurry nozzle through a feeding system; conveying the adhesive to an adhesive nozzle; feeding simultaneously by the slurry nozzle and the adhesive nozzle; performing layered printing; and dewaxing and sinteringa dried blank. The rapidly solidified and formed ceramic material provided by the invention has advantages of rapid solidification and forming, and high hardness and high strength of ceramics.

Description

Technical field [0001] The invention relates to the technical field of 3D printing, in particular to a rapidly solidified ceramic material and a 3D printing method thereof. Background technique [0002] In the 1990s, the Massachusetts Institute of Technology invented a three-dimensional printing technology, which is based on a digital model file, using powdered metal or plastic and other adhesive materials to construct objects by printing layer by layer. . In the past, it was often used in mold manufacturing, industrial design and other fields to make models, and now it is gradually being used in the direct manufacturing of some products. Especially some high-value applications (such as hip joints or teeth, or some aircraft parts) already have parts printed using this technology. With the in-depth research on the application of 3D printing technology in ceramic materials, the use of 3D printing ceramic devices has become a reality. Traditional ceramic production uses pottery c...
