Pairing method and system for part slice and support file for laser additive manufacturing

Abstract

The invention discloses a part slice and supporting file paring method for laser additive manufacturing. According to the method, layering files used for describing parts and supports are distinguished and classified in multiple layering files loaded in batch; for each layering file used for describing the parts, the layering file which is correlated to a file name of the layering file used for describing the parts and is used for describing the supports is found from the layering file category used for describing the supports; and according to the minimum bounding box correlation of the partlayering file and the support layering file with the same name, whether the part layering file and the support layering file with the same name are matched is judged. According to the paring method and system, file names and bottommost height are adopted to distinguish the part layering files and the support layering files, and the risk of laser additive processing failure caused by a naming errorand support generation omission during part file preprocessing is lowered; and through the spatial relation of minimum bounding boxes, the paring relation of the supports and the parts is further confirmed, and the problem of wrong paring caused by spatial stacking of multiple parts with the same name is prevented.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and more specifically relates to a method and system for pairing part slices and supporting files for laser additive manufacturing. Background technique [0002] Additive Manufacturing (AM), also known as 3D printing technology, is a technology based on digital part files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. . In order to prevent problems such as dumping of the sintered or solidified semi-finished products caused by the movement of the scraper in the laser additive manufacturing, it is necessary to generate support files for the part files, and 3D print the corresponding parts before 3D printing the parts. support, and form a relatively firm connection between the support and the substrate, and between the support and the parts. When using third-party slicing software and support generation software to achieve slicin...
