Abstract

The invention provides an optical system, an irradiation control system and applicable 3D printing equipment. The optical system comprises a projection device for irradiating optical radiation to a preset printing reference surface in a surface projecting manner, and a control device for compensatively controlling the projecting device based on captured and detected optical radiation intensity of the projecting device and corresponding irradiation parameters so as to enable actual characteristics of an optical curing layer cured by the projecting device to match with corresponding expected characteristics. The optical system can compensatively control the corresponding power, irradiation time length, gray level and the like of the projecting device through detecting normal optical radiation intensity attenuation of the projecting device in the use period, effectively reduces such product quality problems as insufficient thickness of the curing layer and part breakage caused by equipment aging, meanwhile, obviously prolongs the service life of the projecting device, and improves the stability of curing each curing layer in the service life.

Description

technical field [0001] The present application relates to the field of three-dimensional object manufacturing based on photocuring, and in particular to an optical system, an irradiation control method and applicable 3D printing equipment. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal, plastic and resin to construct objects by layer-by-layer printing. 3D printing equipment manufactures 3D objects by performing this type of printing technology. 3D printing equipment is widely used in molds, customized products, medical fixtures, prostheses and other fields due to its high molding precision. [0003] Among the various 3D printing devices currently on the market, a printing device based on stereolithography uses a method of solidifying and accumulating photo-curing materials layer by layer to produce three-dimensional objects. Due to its fi...
