Description

3D print head cleaning system

Technical Field

Background

The 3D printer builds a three-dimensional model through an additive manufacturing method. The wax pattern 3D printer belongs to one type of additive manufacturing equipment, and the wax pattern 3D printer takes blue wax as a printing material and white wax as a supporting material, sprays high-temperature heated wax to a printing platform, and builds a model by stacking layer by layer. As the wax-spraying 3D printing model has the advantages of high precision, smooth surface and the like, the wax-spraying 3D printer is widely applied to the manufacturing industries of jewelry, aerospace, engines and the like. The printing materials used by the wax-spraying 3D printer are white wax and blue wax, the wax is filled in a container, the container is filled in an ink supply assembly, the blue wax in the container flows into the ink supply assembly and flows into a spray head through high-temperature heating, and the spray head prints the wax on a printing panel layer by layer to construct a three-dimensional model.

After the printing of the existing wax pattern 3D printer is finished, residual waste wax is left in a wax cavity in the spray head and at the position of the nozzle. These waste waxes may block the nozzles, causing the print head to fail to eject, and thus, the print head needs to be cleaned periodically. Current shower nozzle clearance mode uses artifical clearance, prints the shower nozzle in the clearance and need heat messenger wax and melt, but this kind of clearance mode leads to the clearance personnel to scald very easily, leads to the shower nozzle clearance inconvenient.
