3D printing system

Abstract

The invention belongs to the technical field of rapid proto-typing and discloses a 3D printing system. The 3D printing system comprises an ink-jet printer, a printing drive controller and a rapid proto-typing platform, wherein the ink-jet printer comprises a shell, a printer main board, a first drive mechanism, a printer cross beam, a binder supply box and a first sprayer; the first sprayer is installed on the printer cross beam; the binder supply box is connected with the first sprayer; the printer main board drives the first sprayer to move along the X axis and controls the first sprayer to spray binders towards powder; the printing drive controller drives the printer cross beam to move along the Y axis; the rapid proto-typing platform comprises a supporting frame, a proto-typing cylinder, a powder cylinder and a powder spreading roller; and the powder spreading roller is installed on the printer cross beam and consistent with the printer cross beam in longitudinal direction. Various kinds of parts can be formed when the binder is sprayed, high-performance plastic parts can be formed by directly spraying and printing resin, selectable materials are more diverse than FDM and SLA, the cost is low, and precision is high.

Description

technical field [0001] The invention belongs to the technical field of rapid prototyping, and more specifically relates to a 3D printing system. Background technique [0002] 3D printers are mainly divided into desktop 3D printers (personal consumption level) and industrial 3D printers (industrial level). According to the sales volume of "2016 Global 3D Printer Market Status" released by the research organization, 96% are personal / desktop 3D printers, and sales increased by 27% year-on-year. It can be seen that the market prospect of desktop 3D printers is broad. It is not only widely used in conceptual models such as architectural models, medical models, teaching models, and industrial samples, but also can print ceramic products, small toys (models or task dolls), and gadgets. , portraits in the 3D experience hall, etc. [0003] However, at present, domestic desktop 3D printers still have many shortcomings: (1) It is difficult to achieve color printing; (2) Core technolo...

AI Technical Summary

Problems solved by technology

[0003] However, at present, domestic desktop 3D printers still have many shortcomings: (1) It is difficult to achieve color printing; (2) Core technologies such as lasers, software, and materials still rely on imports, and the manufacturing cost is relatively high; (3) Desktop 3D printers currently on the market There are only two technologies of FDM (Fused Deposition Modeling) and SLA (Light Curing), among which FDM has slow printing speed, low precision, and severe material restrictions, so it can only print plastics; while SLA has high speed and high precision, but equipment and materials High cost and high environmental requirements, need protection from light
