Embodiment Construction

[0018] The core of the present invention is a multi-material DLP three-dimensional printing method and its printing equipment. In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with specific examples.

[0019] refer to figure 1 , figure 1 It is a front structural view of a preferred embodiment of a multi-material DLP three-dimensional printer. Since the multi-material DLP three-dimensional printer proposed by the present invention can print two or more photosensitive resin materials, the number of specific resin tanks installed can be adjusted according to the needs of actual model printing. In this embodiment, three resin tanks are taken as an example for illustration.

[0020] A multi-material DLP three-dimensional printer, the printer includes a vertical motion platform 1, a model building table 2, a first resin tank 4, a second re...

Abstract

The invention provides a multi-material digital light processing (DLP) three-dimensional printing method and printing equipment thereof. The core of the multi-material DLP three-dimensional printing method lies in the multi-trough switching technique, that is, two or more resin troughs containing different kinds of photosensitive resin are arranged below a model building table, and the resin troughs are installed on a horizontal motion mechanism controlled by a motor. Each resin trough can be directly moved to the position below the building table when needed. After printing of one material is completed, the resin trough containing another material is horizontally moved to the position below the building table, the material replaces the original material to continue to receive irradiation of a projector, and thus printing operation can be continued. The overall arrangement of the multi-material DLP three-dimensional printer is conducted according to a lower exposure type three-dimensional printing system, the single trough structure and the motion mode of existing DLP three-dimensional printing equipment are converted into a multi-trough structure, printing of various resin materials can be conducted so that individual requirements of models can be met, and accordingly the application range of the DLP three-dimensional printing technology is broadened.

Description

technical field [0001] The invention relates to a multi-material DLP three-dimensional printing method and a printing device based on the method. The printing device includes a mechanical structure component, a control system and a DLP projection system. The invention belongs to the field of three-dimensional printing rapid prototyping manufacturing (rapid additive manufacturing technology). Background technique [0002] Three-dimensional printing or rapid prototyping (RP) technology is an advanced manufacturing technology developed in the late 1980s and early 1990s. It is an additive manufacturing technology based on the idea of ​​discrete accumulation, a "bottom-up" material additive manufacturing method, that is, through computer technology, the material is connected and accumulated layer by layer according to the three-dimensional digital model of the part, so as to manufacture the entity. Component. The manufacturing process is reduced from complex three-dimensional p...
