Workpiece typesetting method for three-dimensional photocuring 3D printing

Abstract

The invention discloses a workpiece typesetting method for three-dimensional photocuring 3D printing, and relates to the technical field of 3D printing. The method comprises the following steps of (1) analyzing the characteristics of workpieces to be machined; (2) screening and sorting the workpieces to be machined, and separating out time-sensitive workpieces and time-insensitive workpieces; (3) typesetting a first row of time-sensitive workpieces; (4) typesetting a second row of time-sensitive workpieces; (5) typesetting the remaining time-sensitive workpieces; and (6) typesetting the time-insensitive workpieces. By means of the method, the time-sensitive workpieces and the time-insensitive workpieces are distinguished, the time-sensitive workpieces are intelligently placed on a printing plate, the time-sensitive workpieces are rotated and arranged according to the size, height and angle of each workpiece, the accumulated distance of back-and-forth movement of a scraper on each layer is reduced, and meanwhile, the workpieces are conveniently shoveled and taken.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a workpiece typesetting method for stereolithography 3D printing. Background technique [0002] Stereolithography 3D printing technology, which is a kind of rapid prototyping technology, is a technology based on digital model files, using bondable materials such as powdered metal or plastic, and constructing objects by layer-by-layer printing. Applied in many fields. [0003] Stereolithography 3D printing requires a scraper to squeegee the workpiece one or more times for each layer printed. The layout of the workpiece has a great impact on the time spent on 3D printing, and it also affects the convenience of picking up the parts. In the case that the height of the workpiece remains unchanged, how to arrange the workpiece reasonably to minimize the cumulative movement distance of each layer of the scraper is particularly important for reducing 3D printing time an...

Problems solved by technology

[0004] The purpose of the present invention is to provide a workpiece typesetting method for stereolithography 3D printing. By distinguishing between time-sensitive and insensitive workpieces, the time-sensitive workpieces are intelligently placed on the printing board, and the size, height, and angle of each workpiece are adjusted according to the size, height, and angle of each workpiece. Rotation and arrangement reduce the accumulative distance of the back and forth movement of the scraper on each layer, and solve the problems of low efficiency of manual adjustment and long printing time in the existing typesetting
