The invention discloses a rapid photo-curing LCD 3D printer. The printer comprises a machine frame, a Z-axis motion module, a resin groove, an LCD liquid crystal screen and a light source, wherein theZ-axis motion module, the resin groove, the LCD liquid crystal screen and the light source are arranged on the machine frame, the Z-axis motion module is connected with a liftable forming platform, the forming platform, the resin groove, the LCD liquid crystal screen and the light source are sequentially aligned from top to bottom, the bottom surface of the resin groove is a transparent mold, thelight source is an ultraviolet light source, and the LCD liquid crystal screen is a high-definition black-and-white LCD liquid crystal screen with a picture input playing function driving plate. Compared with a color LCD liquid crystal screen, the black-and-white LCD liquid crystal screen is not provided with a color filter layer specifically for processing color display, no color filter sheet isarranged in a cell lattice of each pixel point, and ultraviolet light can be directly transmitted, so that the 3D printing precision, the printing speed and the printing success rate are greatly improved.
Description
technical field [0001] The invention relates to an LCD 3D printer, in particular to a fast photocuring LCD 3D printer. Background technique [0002] 3D printing technology is now a popular technology for additive manufacturing. It is different from the traditional subtractive processing and manufacturing industry. It manufactures products through the principle of multi-layer superimposed growth, which can overcome special structural obstacles that cannot be realized by traditional mechanical processing. In industrial production There are great advantages, and the simplified production of arbitrary complex structural parts can be realized. One of the 3D printing technologies is called photocuring 3D printing, which has quickly become a research hotspot because of its small size and simple technology. The existing light-curing 3D printing technology is divided into three types: laser three-dimensional printing technology SLA (curing with laser point light source), DLP (curing...
