Photocuring multi-material 3D printer

Abstract

The invention discloses a photo-curing multi-material 3D printer which comprises a plurality of feeding modules, each feeding module can provide one printing material and can work independently, the feeding modules can be automatically switched during printing, gradient forming of various ceramic materials can be achieved in the mode that materials are changed through a plurality of charging barrels, and the printing efficiency is improved. Multi-gradient color printing of ceramic materials of different materials, different components and different colors can be achieved through the structure designed in the patent, the ceramic materials of different properties are integrally formed, and the problems that current printing materials are single and the like are solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a multi-material photocuring 3D printer for realizing multi-material printing Background technique [0002] DLP technology uses a higher-resolution digital light processor to cure liquid photopolymers and cures liquid polymers layer by layer, that is, photocuring technology. After being solidified into a surface in the XY direction, the three-dimensional printed ceramic parts are completed layer by layer through the movement of the lifting table in the Z axis direction. [0003] The existing DLP printing process is to place all the materials in the material tank, and immerse the printing table in the material tank for photo-curing printing. In this process, the material thickness of each layer is limited by the depth of immersion of the printing table, so the thickness of the material layer is controlled. more difficult. [0004] At present, most of the equipment that uses ...

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 with different materials. Move different troughs to the position of the printing table for printing. Every time a material is changed, the trough needs to be moved once. In this way, the efficiency of multi-material printing is not high, and the quality of the printed product is not good.

Moreover, the structure of this trough replacement mechanism is complicated, requiring a separate power mechanism, and the steps of replacing the trough are cumbersome, which increases the cost of post-processing
