Abstract

The invention provides a printing method and structure, and relates to the technical field of printing. The printing method comprises the following steps of determining a target curing area, wherein the target curing area is a pre-printed image area; obtaining a curing shape corresponding to the target curing area, wherein the curing shape is a pre-printed image shape; adjusting an exposure area according to the curing shape, wherein the exposure area is an area irradiated on a target plane, and the target plane is a plane formed by curing material; exposing curing material according to the corresponding position of the target curing area on the target plane, the exposure area and the exposure time, and judging whether the information corresponding to the target curing area meets area condition or not; and if the information corresponding to the target curing area does not meet the area condition, re-determining the target curing area until the re-determined target curing area meets the area condition. The method has the advantages that the exposure area of photosensitive resin in the irradiation area is increased, the curing area is not limited easily, so that printing requirements of a large area can be met.

Description

technical field [0001] The present invention relates to the technical field of printing, in particular to a printing method and structure. Background technique [0002] There are more and more light-curing processes based on DLP (Digital Light Processing, digital light projection). In this process, liquid photosensitive resin is used as raw material, and the photosensitive resin is used to cause polymerization reaction under the irradiation of an optical machine, so as to complete the curing of the photosensitive resin. A molding process. [0003] In related technologies, CAD (Computer Aided Design, computer-aided design) technology is used to generate a three-dimensional solid model, a two-dimensional cross-sectional image is obtained by using computer software to slice the three-dimensional solid model, and the two-dimensional cross-sectional image is irradiated into a liquid state through a digital projector. The surface of the photosensitive resin cures the resin in the...
