Abstract

The invention discloses a light equalizing method for an LCD photocuring 3D printer. The light equalizing method comprises the steps of acquiring an initial gray value of each pixel point in image data to be printed; acquiring a pre-stored light equalization compensation value, and performing difference calculation on the pre-stored light equalization compensation value and the initial gray valueto obtain a target gray value; and controlling an LCD to perform photocuring printing on the image data to be printed according to the target gray value. According to the method of the invention, theproblem in the prior art that photocuring 3D printing exposure is not uniform can be solved, and the printing quality is improved. The invention further correspondingly discloses a light equalizing device for the LCD photocuring 3D printer and the printer.

Description

technical field [0001] The present application relates to the technical field of 3D printing, in particular to a method and device for homogenizing light for LCD photocuring 3D printers. Background technique [0002] Currently, photocuring 3D (3Dimensions, 3D) printers usually use a single light source or a matrix light source. Due to the error of the lamp bead itself, the limitation of the manufacturing precision of the optical device and the error of the light transmission of the LCD (Liquid Crystal Display, liquid crystal display), the magnitude of the light energy of the curing plane is deviated. For example, the energy in the middle of the screen may be high (e.g. 2000μW / cm 2 ), while the surrounding energy may be lower (for example, 1700μW / cm 2 ), or the energy distribution of the entire screen presents an irregular distribution, and the distribution is uneven. The uneven distribution of light energy will lead to uneven exposure of the printed model and poor printin...
