Embodiment Construction

[0053] The embodiment of the present invention describes a light-curing three-dimensional printing method, which can reduce the internal stress generated when the light-curing resin is cured in a large area, thereby improving the degree of warpage and deformation of the printed workpiece.

[0054] figure 1 The basic structure of the photo-curing 3D printing device is shown. This 3D printing device 100 includes a material tank 110 for accommodating photocurable resin, an image exposure system 120 for curing the photocurable resin, and a lift table 130 for connecting molded workpieces. The image exposure system 120 is located above the material tank 110 and can irradiate a beam image to cure a layer of photocurable resin on the liquid surface of the material tank 110 . Every time the image exposure system 120 irradiates the light beam image to cause a layer of photocurable resin to cure, the lifting table 130 will drive the formed layer of photocurable resin to drop slightly, a...

Abstract

The invention relates to a light curing type three-dimensional printing method and device. The light curing type three-dimensional printing method comprises the following steps that a three-dimensional data model of a printed object is obtained; the three-dimensional data model is divided into multiple layers; for at least some layers of the three-dimensional data model, the exposed area and internal area of each layer are recognized; for the exposed area in each layer, each layer is exposed, and for the internal area in each layer, one exposing process is carried out on every multiple layersat intervals.

Description

technical field [0001] The invention relates to three-dimensional printing technology, in particular to a photocuring three-dimensional printing method and equipment. Background technique [0002] 3D printing technology is based on the computer 3D design model, through the software layered discrete and numerical control forming system, using laser beams, hot-melt nozzles, etc. to accumulate metal powder, ceramic powder, plastic, cell tissue and other special materials layer by layer Bonding, and finally overlaying and molding to create a solid product. Unlike the traditional manufacturing industry, which shapes and cuts raw materials through mechanical processing methods such as moulds, turning and milling, and finally produces finished products, 3D printing transforms 3D entities into several 2D planes, and processes materials and superimposes them layer by layer for production, which greatly The manufacturing complexity is reduced. This digital manufacturing mode does no...
