Abstract

The invention relates to a photocuring 3D printer. The photocuring 3D printer comprises a plurality of light-emitting sources, a grid plate, a lens and an LCD liquid crystal light-transmitting screen, wherein the multiple light-emitting sources are uniformly arranged and emit scattered light rays simultaneously; the grid plate is located above the light-emitting sources, a vertical light channel is formed in the position, corresponding to the position over one light-emitting source, of the grid plate, the light-emitting sources are located in the center of the light channel, and the light channel is defined by vertical light-proof side walls limiting light reflection; the lens is located above a light guide part, and a condensing lens unit is formed at the position, corresponding to the position over one light channel, of the lens; and the LCD liquid crystal light-transmitting screen is positioned above the lens, and the LCD liquid crystal light-transmitting screen is provided with a pixel dot matrix. According to the photocuring 3D printer, the control requirement for the light sources is simplified, the light uniformity is improved, and the product curing effect is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for photocuring a 3D printer optical machine, a printer and a light-emitting display. Background technique [0002] 3D printing technology is to obtain a 3D object by printing a 3D model layer by layer. Existing 3D printing technologies include LOM technology and photocuring technology, among which photocuring technology is widely used. Photocuring technology is to polymerize and cure the resin under light, while the part that is not exposed to light will not be cured. Some existing light-curing 3D printers use LED displays to generate exposure patterns. The LED display is a display composed of light-emitting diodes, so it is necessary to drive the light-emitting diodes of the LED display to obtain the corresponding exposure pattern. This exposure method needs to control the brightness and brightness of the LED light well. Exposure compensation and other parameter...
