Problems solved by technology

At present, there are very few low-density 3D printing ceramic materials, which greatly limits the selection of 3D printing materials.
Moreover, the mechanical properties such as impact strength of existing 3D printed ceramic materials still need to be further improved.

Description

technical field [0001] The invention relates to a ceramic, in particular to a high-strength ceramic material and its preparation method and application. Background technique [0002] 3D printing, also known as additive manufacturing, is a type of rapid prototyping technology and is known as the core technology of the "third industrial revolution". Compared with traditional manufacturing technology, 3D printing does not need to manufacture molds in advance, does not need to remove a large amount of material during the manufacturing process, and can obtain the final product without going through complicated forging processes. Therefore, structural optimization and material saving can be achieved in production. and save energy. 3D printing technology is suitable for new product development, rapid single-piece and small-batch parts manufacturing, complex-shaped parts manufacturing, mold design and manufacturing, etc., and is also suitable for the manufacture of difficult-to-pro...
