Description

Technical Field

[0001] The utility model relates to the technical field of ceramic processing, in particular to an anti-corrosion feeding bin of light-curing ceramic forming equipment. Background Art

[0002] Additive manufacturing (3D printing) is a technology that uses the method of gradually accumulating materials to manufacture physical parts. Compared with traditional material removal-cutting processing technology, it is a "bottom-up" manufacturing method.

[0003] At present, the 3D printing technologies widely used in the industrial field include: Selective Laser Melting (SLM), Selective Laser Sintering (SLS), Stereolithography (SLA, DLP), Hot Melt Extrusion Molding (FDM), etc. 3D printing materials can include metals, photosensitive resins, ceramic materials, polymers, etc. The initial state of the molding material can be powder, liquid, paste slurry, filament, etc.

[0004] Photocurable ceramic 3D printing materials are generally mixed with photosensitive resin, ceramic powder, photoinitiator, dispersant, defoamer, etc., in liquid or paste form. When the solid content is very high, the ceramic material for 3D printing is generally in paste form. The use process is: a certain amount of material is squeezed out, the material is spread on the working substrate with a scraper, and the material is cured with ultraviolet wavelength light (usually ultraviolet laser galvanometer scanning) so that this layer forms a connection with the previous material, and the layers are stacked and cured layer by layer to finally obtain a formed part.

[0005] The curing process of this high-solid content ceramic slurry is similar to the laser selective melting (SLM), laser selective sintering (SLS), and laser curing (SLA) technologies, which all involve the scraping process of the scraper on the workbench. The material bin is raised to a certain height, and the scraper pushes the printing material to the substrate on the work bin. The material is solidified through laser scanning, the work bin drops a layer thickness, and the material bin is raised a certain distance. This is repeated to achieve additive manufacturing. The smaller the 3D printing layer thickness, the finer the molded parts. In order to achieve high printing accuracy, the material after laying should have a high flatness. Therefore, the distance between each position of the printing substrate and the scraper should be kept constant, otherwise the printing accuracy will be lost, and it will be unfavorable for the curing of the first layer, resulting in printing failure.

[0006] With the development of 3D printing technology, ceramic 3D printing technology has been widely used in the fields of architecture, handicrafts, etc. However, during the use of the existing ceramic 3D printer feed bin, due to the strong corrosiveness of the ceramic slurry, it is easy to cause damage to the feed bin, affecting the normal use and service life of the equipment. Therefore, it is of great practical significance to develop a ceramic 3D printer feed bin with anti-corrosion function. Utility Model Content
