Technical Field

[0002] 3D printing, also known as additive manufacturing, is a rapid prototyping technology with the advantages of short production cycle, complex printable structures, integrated manufacturing, and low cost of personalized products. It has broad application prospects in the fields of industry, medicine, aerospace, etc. Compared with the production process of traditional ceramic sanitary ware, the molding and firing time of 3D printing ceramic sanitary ware is greatly shortened, and the molding of ceramic sanitary ware is easier, and the molding can also be more complex and rich. You only need to design the model on the computer for printing without spending a lot of time making the mold.

[0003] Existing ceramic 3D printer slurries lack a synchronous mixing structure for the slurry, which makes the ceramic slurry inside the slurry box easily layered and uneven, and also lacks a secondary way to make the slurry uniform during extrusion and transportation, causing the slurry to have uneven uniformity as the printing time increases.

[0004] Therefore, it is particularly important to design a ceramic 3D printing device to change the above technical defects and improve the overall practicality. Utility Model Content
