Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a 3D printing mud storage tank capable of draining all mud materials. Background Art

[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses adhesive materials such as powdered metal materials, plastics, and ceramic clay to construct objects by printing layer by layer.

[0003] Ceramics can also be formed through 3D printing, which requires clay for printing ceramics. However, the existing clay is stored in a clay storage tank, one end of which is an air inlet and the other end is a clay outlet. When in use, air is taken in from the air inlet to squeeze the clay out of the clay outlet. Figure 1 However, there is a problem when using this type of mud storage tank. When only about one-third of the mud is left, it is easy to become perforated and cannot be used (i.e., the air entering the air inlet passes through the mud and is discharged from the mud outlet), causing serious waste. Utility Model Content

[0004] The utility model proposes a 3D printing mud storage tank which can drain all the mud materials, thereby solving the problem that the mud materials cannot be fully utilized when the existing mud storage tanks used for ceramic 3D printing are used, resulting in serious waste.

[0007] Preferably, the mud storage tank is a cylindrical tank body, and the mud storage cavity is a cylindrical cavity.

[0008] Preferably, the mud storage tank comprises a tank body and an end cover, and the end cover is connected to one end of the tank body by threads.

[0009] Preferably, the air inlet or push rod hole is opened on the end cover.

[0010] Preferably, an air inlet is provided at the tail end of the mud storage tank, and a safety valve is also connected to the tail end of the mud storage tank.
