Problems solved by technology

[0003] The existing DLP printing process is to place all the materials in the trough, and immerse the printing table into the trough for light-curing printing. In this process, the material thickness of each layer is limited by the immersion depth of the printing table, so the thickness of the material layer is controlled. more difficult
[0004] At present, the vast majority of 3D printing equipment using DLP technology can only print one material, which limits the demand for printing products wi

Example Embodiment

[0031] Example:

[0032] A light-curing multi-material 3D printer includes multiple sets of feeding modules, each set of feeding modules provides a printing material, and the printing materials can be of different materials, different components, and different colors, and each set of feeding modules works independently; The sleeve supply module includes at least one storage tank for storing printing material. The feeding module described therein adopts a casting process to cast the printing material to the printing area. The feeding module further comprises: a glue spraying valve connected with the storage tank for controlling the spraying of printing materials, and a casting nozzle connected with the glue spraying valve. A scraper is provided behind the casting nozzle; the glue spray valve is preferably a pneumatically controlled ejector pin type, and the ejector pin valve of the glue spray valve is opened or closed by controlling the on-off time of the air circuit. The front-
