Description

Color ceramic 3D printer nozzle

technical field

The utility model belongs to the technical field of 3D printing, in particular to a nozzle of a color ceramic 3D printer.

Background technique

3D printing is widely used in medicine, aerospace technology, archaeological relics, manufacturing, construction and other industries. For ceramic materials, its 3D printing technology is difficult to process, and there are many unresolved problems, such as excessive surface roughness, unsatisfactory mechanical properties, excessive porosity, and low precision of parts.

Existing ceramic 3D printers use ceramic slurry as a raw material. Based on the excellent molding characteristics of ceramic slurry, the ceramic slurry is then extruded through a nozzle to achieve 3D printing of ceramic materials. However, the existing ceramic 3D printers can generally only print one color slurry. When multi-color printing is performed, a multi-nozzle 3D printer is required. When the multi-nozzle 3D printer is working, each nozzle corresponds to a color of printing. For slurry materials, when the color needs to be changed during the printing process, it is necessary to replace the nozzles corresponding to different colors, and the process of switching nozzles is cumbersome, resulting in low efficiency of multi-color printing, limited color types, and poor surface refinement of the model.
