Abstract

The invention provides a liquid crystal device and a 3D printing system. The liquid crystal device comprises a first liquid crystal box and a second liquid crystal box which are parallel to each otherand arranged in an overlapped mode. The first liquid crystal box is a bi-stable liquid crystal box. Through the strong reflection ability of the first liquid crystal box on light under the powered-off condition and the blocking effect of the second liquid crystal box on the light under the powered-off condition, the light transmissivity is decreased jointly, the black state is generated, the transmissivity of the black state is decreased, thus the contrast ratio of the liquid crystal device can be increased, and the printing accuracy of the 3D printing system can be improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, and in particular to a liquid crystal device and a 3D printing system. Background technique [0002] 3D printing technology is based on the computer three-dimensional design model, through the software layered discrete and numerical control forming system, using laser beams, hot-melt nozzles, etc. to accumulate and bond special materials such as metal powder, ceramic powder, plastic, and cell tissue layer by layer , and finally stacked and formed to produce a physical product. Unlike the traditional manufacturing industry that shapes, cuts, and finally produces finished products through mechanical processing such as moulds, turning and milling, 3D printing transforms three-dimensional entities into several two-dimensional planes. The complexity of manufacturing is reduced. This digital manufacturing mode does not require complex processes, huge machine tools, or a lot of manpower. Parts of ...
