[0002] As an important structural material, ceramic materials have the advantages of high strength, high hardness, high temperature resistance, and corrosion resistance. They are widely used in both traditional industrial fields and emerging high-tech fields; The key is that the main molding methods at present are: extrusion molding, grouting molding, dry pressing molding, gel injection molding, etc. These methods first prepare corresponding molds according to the requirements of ceramic products. Changes, the need to re-prepare the mold, long production cycle, high production cost, and limited types of shapes, devices with complex structures cannot use traditional molding methods, and material waste is easy to produce during production; however, with the rapid development of industry, these Traditional molding methods can no longer meet the requirements of certain fields. 3D printing molding is a new molding method that has developed rapidly in recent years. The main advantages of this method are: high manufacturing precision, short production cycle, complex shape manufacturing, and personalized higher degree

[0003] So far, the technologies applied to ceramic 3D printing mainly include layered solid manufacturing (LOM), fused deposition modeling (FDM), shape deposition modeling (SDM), inkjet printing molding (IJM), stereolithography (SLA), Selective laser sintering (SLS); but the fusion deposition modeling precision is low, the vertical strength is small, the molding speed is slow, and the raw material is expensive; the shape deposition molding needs to be supported, and the support of the final fine structure is difficult to remove; inkjet printing method and selective laser Ceramic materials produced by sintering have large spacing between ceramic powder particles, low green body density, cannot be densified in high temperature sintering, and ceramic properties are low; stereolithography preparation of ceramic materials is costly, the selection range is small, and the molding material Toxic, expensive equipment, etc. cannot be widely used

[0004] In order to overcome the defects in traditional ceramic preparation methods and the deficiencies in the existing ceramic 3D printing technology, there is currently a Chinese patent document with the notification number CN205630921 disclosing an output device for ceramic 3D printers, which can be applied to ceramics Composite materials, reducing labor costs, but the device has the following defects: (1) The storage capacity of the storage tank is limited, which cannot meet the needs of larger products or long-term work; (2) The barrel is directly installed on the motion system of the 3D printer, increasing the Increased the load of the 3D printer, affecting its printing accuracy;

[0005] The Chinese patent document with the notification number CN205889473 discloses a desktop 3D printing ceramic equipment with gas-electric linkage. The air pressure in the storage tank is unstable, which makes the extrusion speed uneven and affects the molding quality
