Abstract

The invention relates to the technical field of 3D printing, in particular to an optical control assembly and a 3D printing device and method, which are used to improve the accuracy of 3D printing. Anembodiment of the invention provides an optical control assembly which comprises a first LCD panel and a second LCD panel arranged in an overlapped manner, wherein the first LCD panel comprises a plurality of first sub pixels; the second LCD panel comprises a plurality of second sub pixels; in the thickness direction of the first LCD panel and the second LCD panel, the orthographic projection ofeach boundary of each first sub pixel is located within the area enclosed by the orthographic projections of the boundaries of at least one of the second sub pixels; and the orthographic projection ofeach first sub pixel partially overlaps with the orthographic projections of at least two corresponding second sub pixels. The optical control assembly, provided by the embodiment of the invention, is used to improve the accuracy of 3D printing.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a light control component, a 3D printing device and a 3D printing method. Background technique [0002] Since the advent of 3D printing technology, it has broad application prospects in health care, manufacturing, military and other fields. [0003] According to the current materials used in 3D printing, the molding technology can be divided into two types. One is the molding technology that uses various powders or films as raw materials and uses lasers to melt and sinter the molding technology; the other uses liquid resin as raw materials. Molding technology that controls light flux to cure liquid resin. Contents of the invention [0004] The main purpose of the present invention is to provide a light control component, a 3D printing device and a 3D printing method. To improve the accuracy of 3D printing. [0005] To achieve the above object, the present invention adopt...
