Description

Technical Field

[0001] The utility model relates to the technical field of inkjet 3D printing, in particular to a circulating filtration and drying system for sodium carbonate support ink used in inkjet printing. Background Art

[0002] In the inkjet 3D printing technology, in addition to using model ink, support ink is also required to support the inclined structure of the model green body or act as a mold for the model green body during the printing process. To ensure that the support green body is easily removed from around the model green body after printing to avoid the influence of the support green body on the model green body during the post-treatment process, sodium carbonate is used as the main material of the support ink, and the support material is removed by washing with water after printing. The nozzle diameter of inkjet printing is relatively small, generally 20 - 50 μm. The sodium carbonate support ink has the disadvantage that it is easy to absorb water, resulting in the re-agglomeration of the sodium carbonate particles that have been dispersed in the ink, thus clogging the printing nozzle during the printing process. If a circulating filtration and drying system for sodium carbonate support ink can be designed, so that the sodium carbonate ink can circulate through a filter element with a pore size of 10 μm, and the water in the sodium carbonate support ink can be volatilized by the heating action of the drying device, the risk of clogging the printing nozzle will be greatly reduced during the printing process, and the printing efficiency will be effectively improved. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a circulating filtration and drying system for sodium carbonate support ink used in inkjet printing, which can realize the volatilization of water in the support ink material before inkjet printing and avoid the re-agglomeration of sodium carbonate particles, prevent clogging of the printing nozzle.
